4 inch portable vertical slurry pump exported to Thailand

Portable vertical slurry pump is  designed for delivering abrasive and high density mixed particles like sand and mud. It is applied for the fields such as metallurgy, mining, coal, power, building materials and environmental protection. The slurry pump is also widely used in the coastal shoal farm’s excavation, river dredging, diking, transformation, sand extraction, the basic construction of farmland and underground works, etc.
The customer wanted to buy a small potable slurry pump that can work in a manhole of 450mm x 600mm to suck seawater and seashell at the bottom of pit.


According to his requirements, the 4 inch portable vertical mud pump was recommended. This kind of slurry pump machine can suck out the seashell, most importantly, it is has the characteristics of easy operation, movement and space saving. The potable slurry pump is made by alloy material to keep the long life of the sand pump. In addition to a full set of pumps, The customer also ordered related impellers, pump casing and pump cover.

Submersible slurry pump with multiple agitators

Product Description

Multiple agitators submersible slurry pump is kind of electrical and mechanical submersible slurry pump equipped with two or three agitators to mix the precipitated sludge at high concentrations. It is suitable for conveying contains the liquid containing solid particles such as sand or coal cinder. This slurry product is made of wear-resisting materials,  it has the characteristics of advanced structure, high conveying ability, strong sewage capability and long life span.

  Product features of multiple agitators submersible slurry pump

  1. All water contact parts are all constructed with abrasion resistant materials – chromium alloy; so pumps have better stability & longer service life.
  2. Unique mechanical seal device can prevent the electric motor from high pressure water and impurities; thus high suction efficiency can be ensured.
  3. Except the main impeller, two or three of extra agitators can be equipped to the main pump body to help break and mix the sludge, greatly improve the work efficiency 
  4. Easy installation, operation and cost saving, no need additional vacuum pump or pump house.
  5. Professional technology support is provided during the whole process of the usage and maintenance.

Application of multiple agitators submersible slurry pump

  1. Suitable for conveying liquid with slurry, solid particles of gravel, cinders, tailings, etc.
  2. Commonly used in river dredging, sand pumping vessel, sewage treatment plants, metallurgical industry, mining, power plants, etc.

Heavy duty big particle gravel sand pump

Product Description

Gravel sand pump is designed for continuously handing the most difficult higher abrasive slurries which contain too big solids. The big particle gravel sand pump is casted as a single pump casing structure with smooth over-current channel .The overflow part is made of hard nickel and high chromium wear resistant alloy. The outlet direction of gravel pump can be adjusted according to the request direction. The gravel sand pump is suitable for delivering strong abrasive slurry containing bigger particles in mining, explosive sludge in metal melting, dredging and so on. The advantages of the pump are heavy flow, easy installation and operation, good performance of NPSH and abrasion resistance.


Product features and application of the gravel sand pump 

1. the gravel pump is horizontal, single pump casing structure centrifugal pump.
2. Use special clamp clamping pump body and pump cover, the pump outlet can be adjusted in the any direction of 360 degrees, easy to install and use.
3. The bearing components with cylindrical structure, easy to adjust the gap between the impeller and the pump body to keep long working life .
4. Bearing with grease lubrication.
5.Gravel pump has three kinds of shaft seal including packing seal, vice impeller seal, mechanical seal.
6. Wide flow channel , good cavitation performance, high efficiency, abrasion resistance.
 7.Transmission methods are: V-shaped V-belt driven, flexible coupling driven,  gearbox transmission, hydraulic coupling driven, thyristor speed control speed  and so on.
8.Over-flow components Material: nickel-containing high-chromium wear-resistant alloy.
9.Using variety speed and variants, making the pump running in the best conditions .
10. Long working life and high operating efficiency can meet a variety of bad working conditions .
Applicable to: sand dredge pumping , dredge river, mining and transport metal smelting .Flow range: 36-3800 m 3 / h Head range: 3.5-80 m. Maximum through particle size: 254 mm .Maximum efficiency: 72% Cavitation allowance: 2-8 NPSH (r).

Dredger parts was ready for Nigeria Customer

Dredger parts like sand pump, water pump, worm reducer, propeller and rubber hose are the important components of dredger. All of these dredger parts are manufactured with strict process and equipment. Ocean Pump is the professional sand pump, slurry pump and dredger designer and manufacturer, it provides one stop solution for all sand pump and dredger requirements.
The customer from Nigeria sent us inquiry about dredger parts for his own designed dredger body in December 2016. The designing and manufacturing of sand dredger is the professional and complex work because dredger is the integrated platform for sand suction, transport and discharge. Our engineers discussed and analyzed the inquiry with the customer for 2 weeks, the scheme was composed by three kind of dredgers:
  1. The master dredger for sand suction.
  2. The relaying dredger to transport sand for long distance.
  3. The shoreline discharge dredger for delivery sand to land.
We cooperated with each other for scheme planning and designing, he constructed the dredger body locally,  we manufactured all dredger parts for him.  We had engaged in such projects, so this project was running smoothly.
According to our engineer’s experience and mature technology, we designed, manufactured and sourced suitable pumps, winches, worm reducer, rubber hoses and propeller for the project.
      (1) Sand pump is used for suck sand on dredger.
      (2) Water pump is to supply high pressure water pump to jet sand up to increase efficiency of sand suction.
      (3) Winch is used on master dredger and shoreline dredger, to drag and lifting the suction hose and suction head.
      (4) Worm reducer is used on sand transport boat, to Control the bottom door open and off.
      (5) Propeller is the dredger navigation equipment.
      (6) Rubber hose is used to suck sand or jetting water into sand.
It took us about 1 month to finish all ordered dredger parts, now they were finished packaging and was ready for delivery. Our customer applied Form M for SONCAP certification from Nigeria Government, which will be helpful to shipment.
