Description
The JS JST-110KB (code 011-130) is an 11 kW, 400v three-phase submersible slurry pump with a built-in agitator. It delivers up to 2,120 litres per minute and a maximum head of 41 metres through a 6-inch top outlet, and passes solids up to 10 mm.
The JST-110KB combines a large outlet with a useful amount of lift, which makes it a good all-round choice for bigger dewatering jobs. The JST-110KBH uses the same 11 kW motor to reach 53 m at up to 1,500 l/min, while the JST-150KB moves up to 2,700 l/min at 46 m if you need more volume.
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.
Features
- 11 kW, 400v three-phase motor
- Up to 2,120 l/min and 41 m head
- 6″ top outlet
- Built-in high-chrome agitator
- Solids passage up to 10 mm
- Double mechanical seals, lip seal and thermal overload protection
Applications
- Mine and quarry dewatering with moderate lift
- Large settling lagoons and silt ponds
- Major civil engineering excavations
- Emergency flood water removal
At 11 kW, check that your generator or site supply and the control panel are rated for the motor before you order. 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.
