Description
The JS Pumps JST-110 KZN-H (code 011-098) is a heavy duty high head submersible slurry pump with a built-in agitator, for sand, silt, sludge and muddy water. It delivers up to 2,585 litres per minute and a maximum head of 29 metres from an 11 kW motor, through a 4-inch top outlet, on a 400v three-phase supply, and passes solids up to 35 mm. It reaches the greatest head in the KZN-H range.
The standard JST-110 KZN uses the same 11 kW motor but is built for volume: up to 4,135 l/min through a 6-inch outlet, to 22 m. Choose the KZN-H when the lift matters more than the volume. If you need more lift with an agitator, the higher-head pumps in the JST KB range are worth comparing.
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 2,585 l/min and 29 m head
- 11 kW 4-pole motor, 1,500 rpm on 50 Hz, 400v three-phase
- 4″ 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 shafts and excavations
- Quarry pits discharging up to settlement lagoons
- Long, steep discharge runs
- Tunnel dewatering with sand and silt
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 standard JST-110 KZN will move considerably more water. A three-phase starter or control panel with motor protection is needed to run it.
