Description
The JS JST-150KB (code 011-134) is a 15 kW, 400v three-phase submersible slurry pump with a built-in agitator. It delivers up to 2,700 litres per minute and a maximum head of 46 metres through a 6-inch top outlet, and passes solids up to 10 mm.
The JST-150KB is a big step up in volume from the JST-110KB (2,120 l/min, 41 m), which suits large pits and lagoons where a lot of water has to move quickly. Only the JST-220KB goes further, with up to 2,800 l/min and 60 m head from a 22 kW motor.
Every KB pump shares the same build. The impeller, suction wear plate and agitator are abrasion-resistant high-chrome iron, the motor casing is cast iron and the shaft is 410 stainless steel, protected by a shaft sleeve where abrasives cause wear. Double mechanical seals (silicon carbide and carbon) run in a separate oil chamber, with an additional lip seal to keep grit away from them. The motor has Class H insulation and thermal overload protection, which trips on high current or high temperature, and JS Pumps uses an enhanced cable entry sealing system. The outlet is at the top, so the pumped liquid passes the motor and helps cool it for continuous duty.

This is a heavy, high-power pump: plan a suitable lifting point and a 15 kW-rated supply and control panel before it arrives on site. These pumps are built for water carrying sand, silt and light slurry with particles up to 10 mm. They are not designed for raw sewage, rag or fibrous material, for which the JST SV sewage vortex pumps are the better choice, or for chemicals and hydrocarbons.
