Application
The ZWQ submersible pump without a float switch is designed for pumping sewage from septic tanks in domestic and agricultural settings, as well as for draining flooded rooms, houses and garages. The pump is also suitable for pumping rainwater and surface water from ponds, lakes and rivers, and for supplying garden ponds.
The grinder integrated into the impeller shreds solid contaminants contained in the sewage before it is pumped onward. The device operates in a vertical position, with a maximum pumped-liquid temperature of up to 35°C.
Features of the ZWQ pump without a float switch
The pump has a motor housing and impeller housing made of gray cast iron. The shaft is made of AISI 304 stainless steel, so it does not corrode during constant contact with sewage and maintains precise impeller alignment. NSK bearings ensure stable operation under the high loads typical of professional use.
The absence of a built-in switch allows the pump to be connected to any external control equipment selected for the specific installation. Thermal protection built into the winding protects the motor from overheating.
