Description
Overview
This 4″ submersible pump range is built for boreholes, wells, and reservoirs with a minimum diameter of 6″. It covers two construction types — a slimline design with a hexagonal shaft and floating impellers for abrasion resistance, and a standard configuration with bronze delivery casing and suction lantern — giving you a model to match almost any duty point from small domestic supply through to higher-volume industrial and agricultural demand.
Applications
