Our JST KZN Industrial Heavy Duty Pumps 400v range of heavy-duty submersible pumps benefit from an in-built high-chrome agitator, which helps keep solids in suspension. The agitator makes this model suited to troublesome slurry and sludge applications and agricultural waste and drainage projects.

The pumps contain a top outlet providing maximum motor cooling for continuous operation. A built-in agitator is specially designed to create a mixing action at the pump inlet, causing the solids to move in suspension and help keep the impeller and flow chamber clear and unclogged.

Heavy duty Hi Chromium impeller, diffuser plate and agitator. Male BSP threaded outlets, direct online starting and 20 metres of power cable. 1500 RPM motors. Maximum liquid temperature 40°C.
