Fully submersible pump for vertical and horizontal installation.
For pumping in commercial areas of:
- Drinking water
- Process water with a max. sand content of 35 g/m³
Multistage hydraulics made of stainless steel with radial impellers in sectional construction. Motor connection in accordance with the NEMA standard. Discharge port with threaded flange and integrated non-return valve.
Three-phase current motor made of stainless steel for direct starting with varnish-insulated and resin-impregnated motor winding. The motor bearings are self-lubricating. Sealing on the fluid side is achieved by a mechanical seal. The motor is designed with a water-glycol coolant and has a hydraulic connection in accordance with the NEMA standard.
To ensure the motor is cooled, always operate the pump whilst it is immersed. Strictly adhere to the limit values for the maximum fluid temperature and the minimum flow velocity.
Depending on the minimum flow velocity, vertical installation is possible with or without a cooling shroud. Always use a cooling shroud for horizontal installation to ensure the required minimum flow velocity.
