JST-150 KZN 400v Industrial Heavy Duty Pump – 011-114

Description

The JS Pumps JST-150 KZN (code 011-114) is a heavy duty submersible slurry pump with a built-in agitator, for sand, silt, sludge and muddy water. It delivers up to 3,305 litres per minute and a maximum head of 32 metres from a 15 kW motor, through a 6-inch top outlet, on a 400v three-phase supply, and passes solids up to 35 mm. It is the high-lift choice in the standard range, reaching 32 m of head.

Its maximum flow is lower than the 11 kW JST-110 KZN, which moves up to 4,135 l/min to 22 m, so choose the JST-150 KZN for height rather than volume. For volume at 15 kW, the JST-150 KZN-L delivers up to 5,910 l/min to 23.5 m on the same 6-inch outlet size.

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.

Features

• Up to 3,305 l/min and 32 m head
• 15 kW 4-pole motor, 1,500 rpm on 50 Hz, 400v three-phase
• 6″ top outlet
• Solids passage up to 35 mm
• Built-in agitator keeps solids in suspension at the inlet
• High chrome iron impeller, agitator and suction cover
• Double silicon carbide mechanical seals in an oil chamber, with lip seal and shaft sleeve
• Water jacket cooling and built-in overload protector

Applications

• Deep excavations and shafts where slurry must climb a long way
• Long discharge runs to remote settling lagoons
• Quarry pits pumping up to processing or settlement
• Tunnel and civil engineering dewatering

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. At low heads the JST-110 KZN or JST-150 KZN-L will move more water. 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.
