The pumps offer single phase motors up to 1.5kW and three phase electric motors up to 7.5kW in power are held ex-stock, although three phase versions up to 22 kW will be able to be built to order.
The submersible drainage pumps offers five different range choices for dewatering, sewage or pumping waste liquids with a high component of soft or hard solids.
The new heavy duty products are designed for the building, mining, industrial, sewage and agricultural waste product sectors and come under five separate product categories including submersible sand and slurry drainage pumps; grinder pumps; sewage or single channel pumps with and without cutters; dewatering pumps and vortex or solids handling pumps.
Typical features include optional slide rails for easy installation and removal, top or side discharge outlets depending on model and a provision for lifting rings for rope suspension or submergence in the liquid material, which can contain up to 70% solids depending on model.
In each instance the five sump pump series pump ranges employ heavy duty construction especially in the materials chosen for the shafts, impellers, agitators, bearings and external bodies, according to the company.
Minimum materials of construction include 300 series stainless steels, hard faced silicon carbide mechanical seals in oil baths and high quality cast iron.
The extra heavy duty KZ/N range feature wear resistant chrome steel and especially hardened materials recognising that these pumps will be subjected to very demanding operating environments.
The KZ/N units also feature heavy duty inlet agitators and are suitable for pumping sand or slurry materials.
The design of the pumps also allows them to be safely run in shallow depths of liquid materials.
