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. Mechanical seal made of wear-proof silicon carbide complete with a sealing ring. It includes heavy duty ball bearing motor with inbuilt overloads.

The pump is to be installed in an upright position for both fixed and portable plants. Do not run your pump dry. To prevent damage, use a rope or chain to position and retrieve your pump - never use the electric cable for this purpose. For a typical installation see page 4 of 4 of this document.
Don't use this pump for recirculating or filtering pools, spas, etc. While these pumps are built to a high safety standard, they are not approved for installations where people will be in the water while they are operating.
