How to choose a submersible centrifugal slurry pump?

Slurry pumps are crucial equipment in industry for conveying slurries containing solid particles. Selecting the right submersible slurry pump directly impacts production efficiency, operating costs, and equipment lifespan. So, how can we select a slurry pump to extend its service life and maximize benefits? Below, TR Solid Control Plant analyzes several aspects of submersible slurry pump design, including determining pump operating conditions based on pump characteristics, rationally arranging slurry pumps, and selecting high-quality slurry pumps.

TR Solids Control's centrifugal slurry pumps are single-stage, vertical cantilever pumps specifically designed for conveying high-concentration solid-liquid mixtures. They are widely used in the transportation of solid-liquid mixtures in industries such as oil drilling, mining, metallurgy, and coal.

I. Product Technical Structure Characteristics

1. Structural advantages

   It adopts a semi-open impeller, and the blade inlet extension is equipped with stirring blades, which can effectively break up sediments and prevent clogging.

   There are no bearings or shaft seals between the pump body and the propeller, achieving a maintenance-free design and outstanding high-temperature resistance.

   The pump shaft has sufficient rigidity, and there is no shaft seal in the submerged part, reducing the risk of leakage.

   For example, the impeller of the TRSB series sand pump adopts a semi-open design, combining packing seal and mechanical seal dual sealing technology to effectively prevent leakage and extend service life.

   
   

2. Materials and workmanship

   The pump body is made of alloy cast iron, which has better wear resistance than ordinary cast iron and extends its service life.

   Impellers, jackets and other flow-through components can be equipped with high-chromium alloy or rubber linings to meet the needs of different working conditions.

   The bearings are imported brands such as SKF to ensure operational stability.

   
   

3. Performance parameters

   Flow range: 20-135 m³/h

   Lift range: 12-60m

   Power range: 3kW-55kW

   Applicable media: solid content ≤45% (mortar), ≤60% (mineral slurry), particle diameter ≤15mm.

II. Application Scenarios and Industry Cases

1. Oil drilling solids control system

   Submersible slurry pumps, as core equipment in mud circulation systems, supply slurry to shale shakers and centrifuges, handling cuttings and additives in drilling fluid. They are commonly used in mud-free systems and shield tunneling mud-water separation systems. For example, in oil drilling, they deliver 200 m³/h of mud at a pressure of 0.3 MPa, working in conjunction with hydrocyclones to achieve efficient separation of sand-sized particles. Tianrui Solids Control provides complete solids control systems to companies such as CNPC and CNOOC, enabling drilling fluid reuse rates to exceed 90%.

   
   

2. Mining and metallurgical industries

   In iron ore beneficiation plants, it is used to transport high-concentration slurries (such as slurries with a solids content of 60%) and handle high-concentration, highly abrasive media. It replaces traditional positive displacement pumps (such as cam pumps) and is more efficient under low flow and high head conditions.

   
   

3. Environmental protection engineering industry

   It is used in river dredging and sewage treatment to transport sand-laden wastewater and prevent sediment from clogging pipes. When used in conjunction with a desander and centrifuge, it achieves solid-liquid separation.

III. Selection Recommendations and Comparison

Select the appropriate slurry pump based on the characteristics of the medium, such as solid content, particle size, and corrosivity.

TR Solids Control's submersible slurry pumps are 30% cheaper and offer customization services (such as impeller material and outlet diameter adjustment). Slurry pump components are interchangeable with those from the Mission brand, reducing users' spare parts procurement costs.

TR Solid Control has obtained ISO9001 certification and American Petroleum Institute (API) certification, and its products comply with the industry standard GB/T 13008-2018 "Centrifugal Slurry Pumps". Its self-developed ceramic-coated impellers have increased wear resistance to 1.5 times that of traditional alloy impellers and have been piloted in a mine in Shanxi Province.

IV. User Cases and Feedback

Feedback from oil drilling customers indicates that the TRSB series pumps have operated continuously for 2,000 hours without failure during shale gas horizontal well construction, extending their service life by 50% compared to previous models.

Mining users use YZ type submersible slurry pumps to transport copper-containing slurry, with an impeller life of up to 12 months (compared to only 6 months for ordinary pumps under the same operating conditions), reducing maintenance costs by 40%.

TR solid control centrifugal slurry pumps have become the ideal choice for solid-liquid transportation in mining, petroleum, and environmental protection fields due to their wear resistance, cost-effectiveness, and fast service.
