WQ-QG heavy duty cast iron grinder sewage pumps

Product Code : SEW - 2

Pump Application:

This range of heavy duty cast iron submersible grinder pumps are suitable for both commercial and industrial use.   These pumps can be used for pumping polluted water containing, fibrous bodies and raw sewage.   Fitted with an effective hardened corrosion resistant grinding device and anti clogging grinder system that reduces pump blockages, maintaining pump efficiencies.   Easy to install with the special coupling device.   Complete with a Sic-Sic carbon ceramic mechanical seal contained in an oil chamber and includes a heavy duty ball bearing motor.
