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.
