Typical applications
- Automatic construction drainage
- Mine and quarry dewatering
- Sewage treatment plants
- Unattended sump drainage
Selection and ordering guide
- Provide the required flow and total dynamic head, including pipe and fitting losses.
- Describe the liquid, solids size, solids concentration, abrasiveness and temperature.
- Confirm sump depth, installation method, discharge connection and required cable length.
- Confirm voltage, frequency, control cabinet, level-control and intelligent-protection requirements.
- For slurry service, provide particle distribution and settling tendency so the agitator and wear materials can be verified.
Installation and service notes
Keep the pump within the minimum operating-water level shown in the catalog, verify rotation before continuous operation, and never lift the pump by its cable. Inspect the strainer, impeller, inlet plate or agitator, mechanical seals and cable entry at planned service intervals. Isolate power and pressure before maintenance.
