400ST-L Light Duty Slurry Pump

Closed Metal Impeller

The 400ST-L uses a closed impeller with an 825 mm diameter. The basic impeller code is STL10147. The impeller works with the pump's internal flow passages to transfer energy to the pumped medium and generate the required flow and head.

Metal Liner and Impeller

The supplied technical chart specifies metal for both the liner and impeller. Material selection is an important consideration when handling solid-containing slurry, particularly where particle impact and abrasion affect wet-end wear. The suitability and service life of the selected metal depend on the actual slurry composition and operating conditions.

Performance Curve for Pump Selection

The supplied performance curve shows flow rate, head, rotational speed, and efficiency relationships. Engineers can use this information to identify a potential operating point and evaluate whether the pump suits the required duty.

The curve is a clean-water performance reference. Actual slurry performance should be assessed with appropriate corrections and application-specific engineering data

Selection Benefits

• Large suction and discharge connections

• Performance curve for flow and head evaluation

• Metal wet-end configuration for suitable slurry applications

• Hydraulic selection based on actual operating requirements
