CNSME is a professional Slurry Pump manufacturer and supplier in China. 

Because they offer longevity, efficiency, and adaptability, horizontal slurry pumps are crucial for sectors handling abrasive slurries. Knowing their values, applications, and maintenance needs allows businesses to maximize performance and reduce expenses.

Slurry pump commissioning must be strictly conducted in accordance with established procedures: Prior to startup, first activate the shaft seal water and adjust it to the specified pressure. Fully open the inlet valve. For non-backflow pumps, water must be injected. After opening the outlet valve to one-quarter, initiate startup; During operation, monitor flow rate, head, current, vibration, and bearing temperature (temperature rise ≤35°C, maximum ≤75°C). Mechanical seal leakage should be ≤3-5 ml/h. Before stopping the pump, flush with clean water for 30 minutes, close the outlet valve first, then shut down the pump, and finally close the shaft seal water and inlet valve. It is strictly prohibited to fully open the outlet valve when stopping the pump to prevent water hammer. Throughout the entire trial operation process, ensure that parameters remain stable, avoid cavitation and overload conditions, to ensure safe operation of the equipment.

Slurry pump including 6 performance parameters: flowrate, efficiency, head, speed, shaft power, permissible suction vacuum height, and NPSHr (net positive suction head)

Adjust the impeller clearance: Loosen the clamp bolt on the bearing assembly and use the adjustment screw to move the bearing assembly forward. At the same time, rotating the shaft clockwise until the impeller contacts the volute liner, and tighten the nut at the front end by adjusting the screw to move the bearing assembly backward, so that the clearance between the impeller and the volute liner will be within the range of 0.5-1 mm;

Slurry Pump Material: High-Chromium Wear-Resistant Cast Iron A05 (KmTBCr27):

This material offers high hardness, with a post-heat-treatment hardness reaching HRC 58-62. It possesses excellent abrasion and erosion resistance (wear resistance). For alkaline mixed liquids, it demonstrates relatively good corrosion resistance, making it suitable for highly abrasive service conditions. The casting process for high-chromium cast iron is complex and challenging, and machining is relatively difficult. Nevertheless, its long service life and moderate cost make it the most widely used material in slurry pump applications.

Looking for unmatched quality and range, CNSME is a top choice. You can depend on their Sand Gravel Pump series, which offers durability and reassuringly smoother operation. Any dredging or mining project can find a pump tailored to its needs.
