How to Choose Power Source for Heavy Duty Sludge Pump

Heavy duty sludge pump is one kind of slurry pump or sediment pump which can be used to extract river sediment, silt or tailing slag, etc. According to the structure,  sludge pump can be divided into three types  such as horizontal, vertical and submersible sludge pump. Some of our customers often have a question on how to choose suitable power source for sediment pump. Normally we choose the power source according to the actual working conditions. Electric motor, diesel engine and hydraulic power are three commonly used power resources to drive heavy duty sludge pump.

Electric Motor Driven Heavy Duty Sludge Pump

We recommend the electric motor as a power source for the heavy duty sludge pump when there is three-phase industrial power at the work site. . Especially in the case of transporting sludge or mud with long distances, it has the following advantages:

1. With electric motor, the sludge pump has low noise and stable operation. Low noise has less impact on the surrounding environment and it is conducive to workers’ construction.
2. The supporting variable frequency control cabinet controls the operation of the electric motor, sot he start-up is more stable. During the operation, the power can be reduced by adjusting the frequency to reduce the useless power consumption, it could meet the requirements of transportation distance, to save power consumption and reduce the construction electricity cost.
3. The electric motor is also easy to maintain.
4. The electric motor connection mode can be directly connected by the coupling and also connected by the pulley. The installation is flexible and the occupied space is also small.
   
   
   
   
   
   
   

Diesel Engine Driven Sludge Pump

If the work site have no electric power supply or needs to be equipped with more than 500 KW electric power, we recommend diesel engine as power source. Diesel engines have the following advantages.

1. The diesel engine has the advantage of large torque, It is especially suitable for long-distance transportation and high concentration conditions.
2. When selecting the diesel engine, the engine rotation speed will be calculated according to the requirements of the heavy duty sludge pump. When calculating the heavy duty sludge pump speed ratio, we usually leave a certain amount of allowance. If the heavy duty sludge pump needs to run at the speed which is higher than the designed speed, the diesel engine power also has a certain margin to ensure safe using.
   
   
   
   
   
   
   

Hydraulic Power Driven Sludge Pump
There are many types of heavy duty sludge pumps,  the hydraulic station is often selected as the power source in some working conditions nowadays. The hydraulic power uses oil liquid as the working medium and uses the oil liquid pressure energy to transmit power. In this way, the heavy duty sludge pump is easy to control, it has a low failure rate, also have good overload protection.
In fact, there is no clear distinction for which kind of power source is better. As long as it is suitable for working conditions, try to use the most cost-effective and easy-to-operate power. This requires the more professional heavy duty sludge pump manufacturer. When communicating with customers, it is necessary to understand the requirements of the working conditions in detail, to provide the best solution for the customer to meet the requirements.

Electric Sand Dredge Pump Used for Construction Mud Conveying

Electric sand dredge pump is also called heavy duty sand pump. Electric sand dredge pump is the kind of sediment pump for extracting mud, fine sand, and other media and transporting them over long distances. The electric sand dredge pump designed by OCEAN Pump is precisely cast by high quality and high wear resistant material. It is suitable for marine mud absorption, sand pumping, reclamation and dock construction. Electric sand dredge pump can also be used for power, metallurgical transportation and river and lake dredging . At present, it is widely used in various conditions such as dredging and embankment in the Yellow River Basin, dredging in the Yangtze River Basin, coastal reclamation, and inland river sand mining.

An engineering company in Zhejiang has undertaken a mud transportation project in the underground engineering. About 5 million cubic meters mud obtained from underground construction requires to be delivered to a place 12 kilometers away from the construction site.
The site is on a relatively congested section of the local traffic, so the government designate the construction period to be 22:30 – 7:00 the next day. It also requires less noise during construction, minimizing the dust pollution, and reducing the impact on the lives of surrounding residents.
The customer currently uses trucks to transport mud to a designated area for stacking. However, this method is less efficient. Trucks need continuous round-trip transportation and can only work at specified times in the evening, which results in lower transporting efficiency. And environmental pollution problems such as dust and spills cannot be avoided. The customer contacted our engineers through our website to inquire whether there were other transportation modes that can improve efficiency while reducing costs and pollution.

OCEAN Pump put great emphasis on this new field and new construction requirements. Through deep communication with customers, OCEAN Pump engineers judged that it is similar to the previous sand pumping and transportation project. Therefore, our engineers recommended sand booster pump mode for sand pumping. The specific construction contents are as follows:

1. Use multiple vertical sediment pumps equip with high-pressure water pumps.Water pumps extract clean water from the river. The water pump can provide high-pressure water to impact the soil layer, thereby forming high concentration mud and water mixture, which is pumped and transported by a vertical sand pump.
2. The mud and water mixture extracted by vertical sand pumps was gathered to one electric sand dredge pump by mud transporting hose then is conveyed by electric sand dredge pump 3km away. There are other two electric sand dredge pumps as booster sand pump, the two sand pumps are in same model. The mixture will be conveyed and discharged to the river 12 km away by the booster pumps.

The Advantages of Electric Sand Dredge Pump

1. The electric sand dredge pump can be used for 24 hours without interruption, which effectively improves the working efficiency. The sand extracted by the sand pump machine will be directly transported to the designated discharge pool through the pipeline, and does not need to be transported by the vehicle, so the work efficiency will be much improved.
2. Compared to truck transporting, sand pump conveying has little impact on traffic. The environmental pollution is also minimal because the sediment is conveyed by pipeline, almost no leaks.
3. The electric motor has low noise during running, it has little effect on the normal life of the surrounding residents.
4. It doesn’t require many people for operation, and there are low requirements for operators. These can reduce the labor cost.

The customer is very appreciative of the electric sand dredge pump, and through inspection, it is judged that this method is conducive to the transportation of building soil. And the customer originally had 7 vertical sediment pumps that can be used, so it is only necessary to purchase a sand pumps as booster pumps. After confirming the plan, the customer immediately signed a purchase contract for 3 sets electric sand pumps and supporting equipment.

The parameters of the Electric Sand Dredge Pump 450 PNS-35

Flow	2600 m³/h
Head	35 m
Power	380 kw
Speed	730 rpm

After confirming the order, OCEAN Pump began to manufacture the sand dredge pump according to the contract. The electric sand dredge pump and supporting equipment were delivered to the customer’s designated site on May 18, 2019. After the complete sets of equipment includes the required pipeline installation finished production, OCEAN Pump engineers started to debug the equipment on site. During the trial operation of the heavy duty sand pump units, the water and mud mixture capacity was about 400 cubic meters per hour which can meet the customer’s expectations. And the overall operation cost is low, and the cost is much lower than the previous truck transportation. The customer is very satisfied with this. In view of the success of this cooperation, the customer is more confident about the next phase of the project (transport distance up to 40 kilometers), so signed a new procurement contract with our company.

The Influencing Factors on the Price of Horizontal Centrifugal Slurry Pump

Horizontal centrifugal slurry pump is specially engineered for transporting high aggressive, viscous and abrasive slurries or large size particles in construction, mining, chemical and industrial applications. There are many factors you would consider such as the size of the manufacturer and their customer group, the scientific research strength, the quality of the pump, the sand effect, the price, the production cycle, and the parts inventory, when you to choose a horizontal centrifugal slurry pump. These factors are based on the strength of the manufacturer and the cost performance of the product.

The calculation method of sand slurry pump cost and sales price are complicated. This article explains the price factors in the selection of horizontal centrifugal slurry pump and how to choose a wearable horizontal centrifugal slurry pump with good quality and low price.

1. Configuration Affects Slurry Pump Price

When you select a horizontal centrifugal slurry pump for your demand,  you should consider the flow capacity, head type, slurry pump materials and manufacturing process, the working conditions, then you ask the supplier for the price. Our engineer will select the appropriate slurry pump type according to  your specified conditions and tell you the price. If you don’t need too long distance or the amount of work is small, the first thing that should be considered is the small slurry pump. There are many  kind of horizontal centrifugal slurry pump with different configurations, and the price has big differences. Therefore, there are many kind of slurry pump can satisfy your demands. The price of sand pump machine cannot be judged solely by caliber.

2. Casting cost affects sand pump price

At present, the most commonly used overflow material of the horizontal centrifugal slurry pump is high chromium alloy. The price of chrome is much more expensive, and the high alloy chrome is resistant to strong abrasion. High quality material has greatly reduced the user’s replacement and time costs.

3. Processing and assembly costs affect slurry pump price

The main parts or components should be precisely machined or processed by professional CNC lathes, then the designed parameters and tolerances of assembly surface can be achieved. Therefore, lathe processing technology or skill affect parts precision. The assembly surface of the horizontal centrifugal slurry pump parts must be tightly jointed so that the assembly will meet the designed parameters. In this way, it will all matched when the accessory is replaced later.

Some standard parts need to be selected during the assembly process of the horizontal centrifugal slurry pump, which is often overlooked by customers. However, the standard parts are the basis for the stability of the horizontal centrifugal slurry pump, and the prices of different parts vary greatly.

4. Product inspection cost affects slurry pump price

Each casting of the horizontal centrifugal slurry pump must pass the material inspection to ensure the stable physical properties. After each part is processed, it must pass the hardness test to ensure the wear resistance and toughness. After each horizontal centrifugal slurry pump is installed, it must pass the clean water test and sealing test to ensure the high efficiency and stable operation.

5. Pre and after-sale costs can affect the price of pump

The horizontal centrifugal slurry pump is the heart of the dredging work. When the customer chooses the horizontal centrifugal slurry pump, it also needs the support of the whole product scheme. Excellent horizontal centrifugal slurry pump manufacturers have a complete team of engineers. In pre-sale communication, it’s necessary to understand the working conditions and horizontal centrifugal slurry pump requirements in detail, then creating a cost-effective horizontal centrifugal slurry pumping system solution. After the team of technical engineers will continue to track and ensure that every pump that is sold out will perform well.

The ocean pump is a professional horizontal centrifugal slurry pump manufacturer. The engineer team absorbs the advanced pump design concepts at home and abroad. The sand dredging pump has more than 20 series and more than 500 specifications. During the casting process, the heat treatment process is carried out twice to ensure the strength and toughness. The Rockwell hardness is over 60. All the standard parts are selected from the brand. With a professional-level inspection team, we have more than 20 pre-sales and after-sales engineers, complete product lines, and all departments work together to make sure the quality. The scientific procurement mechanism will reduce costs, ensuring the user’s procurement costs and achieving benefits.

All in all, back to the original question, how to choose a high-quality and low-cost horizontal centrifugal slurry pump? This problem is seen by the benevolent wise. I believe that after reading this article, you will have your own judgment. In the process of selecting the horizontal centrifugal slurry pump, I hope that the ocean pump will become your reliable partner. We are not the cheapest on the market, but we are a dedicated one-stop sand suction pump solution provider and your friend.

Material Differences of Centrifugal Slurry Pump

Centrifugal slurry pump is commonly used in pumping systems that move sand deposits to a long distance. Centrifugal slurry pump has good price and high performance in our sand pump machines. Small size and volume make centrifugal slurry pump easy to operate, transport and maintain. Centrifugal slurry pump is widely used for tailing, sediment, sand or slurry extraction in the power plant, river, lake, pond, etc.

Every manufacturer of sand dredging pump in the market claims to produce wear-resistant centrifugal slurry pumps. What are the differences? Except the working conditions, sand pumping machine rotation speed and other factors, which kind of casting material is better? This article elaborates on these issues.

1. Material A05, also known as chrome 27, material label Cr27, is mainly used in casting the over-current parts of large particle gravel pump. It is originally used by Australian WAMAN Company in the mining project. This material is a kind of wear-resistant white iron, with the advantages of corrosion resistance and erosion resistance. Compared with other casting material, it contains nickel instead of molybdenum.

2. Material Cr26.It is the over-current parts material of Centrifugal slurry pump. Cr26 is mainly used in submersible slurry pump and vertical slurry pump. Cr26 contains 26% chromium, and also contains nickel, molybdenum, copper. Cr26 has high wear resistance and high performance, so it is suitable for high speed sand suction pump.
   
   
   
   

3. Material Cr28, mainly used in marine sand pump and centrifugal slurry pump. The chromium content is 28%. It also contains nickel and molybdenum. It is harder than Cr26, and has good tensile properties. The application range is very wide.

3. Material Cr15Mo3. Compared with above three casting material, Cr15Mo3 has strongest wear resistance and is also the hardest casting material. But the production of molybdenum and nickel is low, so the price of Cr15Mo3 is very high. The casting parts cost of Cr15Mo3 is twice as much as high-chromium alloy. However China is vigorously mining nickel and molybdenum ore, the market prospect is good.

Wear resistance of the sand pump over-current components is mainly depends on the content of carbon. Then adding trace elements such as silicon, manganese, phosphorus, nickel, chromium, molybdenum, copper, aluminum, boron, vanadium, tin, etc. High wear resistance can be realized by changing the proportion of the elements. In the actual selection, customers can select different types of centrifugal slurry pump and over-current components materials according to the requirements of the sand output.

The centrifugal portable sand pump can work in different complicated working conditions. Centrifugal portable sand pump can be equipped with diesel engine or electric motor.

Our South Africa customers sent us an inquiry about sand suction pump which would be equipped on a portable sand dredger. They have made a 4 inch portable sand dredger by themselves, but the working efficiency was low. So they planned to make a large sand dredger and purchase a larger sand pump to increase the sand output.

Their requirements about the sand dredge pump were as follows.

1. The output was about 100t/h, the discharge distance was about 100m, no requirement of suction head.
2. The water depth was 8m, the sand source was relatively clean, and there were few pebbles and garbage.
3. It was better to use diesel engine connected with the sand pump by belt.
   
   
   
   

We chose 8 inch centrifugal portable sand pump which had thicker pump case, this could extend the wear resistance of the sand pumping machine. Considering the safety of the sand pump, we equipped a protective cover upside of the belt. Besides the centrifugal portable sand pump, we also discussed other details of the portable sand dredger with the customers. We sent the working video of our sand dredger which was shipped to other countries. They were very interested in our simple sand suction dredger. We may have more cooperation in the future.

Why Mining Pumps Can’t be Used to Suck Sand?

Mining pumps are the widely used powerful sand, trash and water handling pumps for efficient dewatering and residue handling in mining industries. Mining pumps are often used to handle particle concentration less than 30% and they are not suitable for sand sucking and dredging. Some many users may select mine pump to suck sand, especially he user who just comes to sand pumping industry. As a professional sand pump machinemanufacturer, we would like  explaining this problem for selection and application of mining pump correctly.

Here are Several Reasons Why Do Mining Pumps Can’t Suck Sand

1.The air in the mining pumps case caused mining pumps can’t suck sand.

In August 2018, Our customer from Malaysia wanted to purchase our sand extraction pump. At first, he considered to put the sand extraction pump on the sand shore, it is about 20 meters away from the surface of the water, then put the rubber hose into water to pump sand. Our engineer didn’t agree with this scheme. We recommended using a jet suction dredger, putting the sand extraction pump in the jet suction dredger for pumping. Because of the air in the centrifugal sand pump case may cause the mining pumps can not suck sand.

The design principle of the mining pumps is when pump is filled with liquid, the centrifugal force is formed by the high speed rotation of the impeller, so that the water is continuously sucked from the sand suction pipe. Almost everyone knows this principle, but when choosing the mining pumps, people often ignore the vacuum suction of the mining pumps. Then vacuum suction of the normal sand pump is about 6 meters, that means when the pump is 6 meters higher than water surface, the mining pump can not suck out the water, and the proportion of the sand is larger. So if the height exceeds 2-3 metiers, the effect of the sand pumping will be greatly reduced. Therefore, in the usual selection, the engineer always advise the user to put the mining pumps in the dredger or on the welding platform, so that the vertical height from water surface to centrifugal inlet is smaller. Moreover, if there is air in the sand pumping machine during work, cavitation will occur and the wear of the pump will increase.

2. Sand quality will affect sand pumping

The mining pumps are based on the foundation of the water pump. The difference between the mining pumps and water pumps is that the mining pump impeller has a wider flow path and better passability. The overflow parts are usually made of wear-resistant materials to ensure the life of sand pumping. But the basic principle is to suck the water and sand out by centrifugal force.

Since some construction sites are perennial sediments, some will have a knot. Therefore, it is necessary to impact the sediment by means of injection. How to achieve injection? It requires a set of high-pressure water gun. Using high-pressure water to disperse the sediment at the bottom of the river, increasing the concentration of the suction, and ensuring the amount of sand. If the sand is knotted for many years and the high-pressure water can’t disperse the sediment, you can use the types of cutter suction or bucket wheel. Using a reamer or bucket wheel to stir the sediment into the water to achieve high concentration.

3. The sand pump can’t suck sand because mining pumps loss or quality problem

After the long-term continuous operation of the mining pump impeller, there will be wear, or the gap between impeller and the front plate of the sand pump will be too large, resulting in a decrease in suction force, which will affect the amount of sand discharged; the mining pumps bearing is damaged, the mining pumps vibration is too large, causing the impeller to be eccentric, which also cause the suction to be affected. At this time, it is necessary to replace the overflow components or bearings.

4. The mining pumps can’t suck sand due to mismatched equipment

There exist power matching, pipeline matching, valve matching issues. The power matching is reflected in the diesel engine or the motor is too small, the power is insufficient, resulting in a problem with the load of the sand pumping machine, which causes the equipment to stop or malfunction; the pipeline is reflected in the leakage of the suction pipe, and the wear of the gasket causes the sand pipe to leak. It will affect the suction of the pumping equipment; the valve is mainly reflected in the excessive density of the bottom valve, the sand can not enter the sand pumping tube, thus affecting the efficiency of sanding.

Usually through these four aspects of investigation, it is basically possible to determine the reasons and solutions why the mining pumps can’t suck sand. This is also the knowledge that every mining pump industry practitioner needs to learn and master.
