The PU-series is a vortex pump designed for handling raw sewage, wastewater, industrial and commercial sump pump applications. The solid handling design provides practically unchokable operation in sewage pumping. Since the pump is made of special resin and stainless steel, it is corrosion-resistant and lightweight.
- Draining sewage from factory, residence, hotel, restaurant, etc.
- Pumping rainwater and springwater at a place where foreign objects are likely to run into the water.
- Transferring wastewater between the tanks at small-scale treatment facility.
