JST-220 KZN 400v Industrial Heavy Duty Pump – 011-116

Description

The JS Pumps JST-220 KZN (code 011-116) is a heavy duty submersible slurry pump with a built-in agitator, for sand, silt, sludge and muddy water. It delivers up to 5,960 litres per minute and a maximum head of 33.5 metres from a 22 kW motor, through a 6-inch top outlet, on a 400v three-phase supply, and passes solids up to 35 mm. It is the largest pump in the standard KZN range, combining the highest flow with the highest head.

The JST-220 KZN-L uses the same 22 kW motor with an 8-inch outlet; on the JS curves it reaches the same maximum flow with a lower maximum head of 29 m. If you do not need this pump’s full capacity, the JST-150 KZN reaches 32 m on a 15 kW motor.

Like every KZN pump, it has a high chrome iron impeller, agitator and suction cover (wear plate) to resist abrasion, with the agitator stirring settled solids back into suspension at the inlet so they are carried out rather than left to block the pump. Double silicon carbide mechanical seals run in an oil chamber, protected by a lip seal and a shaft sleeve. The top outlet and water jacket use the pumped liquid to cool the motor, and the 4-pole motor runs at 1,500 rpm on 50 Hz with a built-in overload protector.

Applications

• Large-scale site and mine dewatering
• Emptying lagoons, settling ponds and flooded pits
• High-volume slurry transfer on quarry and aggregate sites
• Major civil engineering and river works

Built for abrasive solids such as sand, silt, grit and sludge. It is not a sewage pump for rag, wipes and fibres, and is not intended for oils, solvents or chemicals. This is a large, heavy pump on a 22 kW motor: plan lifting gear, cable and a supply rated for its starting load. A three-phase starter or control panel with motor protection is needed to run it.

The JST KZN range

All models are 400v three-phase. Flow and head are maximums from the JS Pumps performance curve. See the JST KZN slurry pump range page for help choosing a model, or compare the KZN-H high head and KZN-L high flow versions.
