Description
The JST-75SKSS (code 011-386) is the largest pump in the JST SK SS stainless steel cutter range. Its 7.5 kW, 400v three-phase motor delivers up to 2,935 litres per minute and up to 24 metres of head through a 4″ outlet.
It is the model to choose when a big corrosive sump needs both high flow and high lift. Compared with the JST-55SKSS it adds 2 metres of head and keeps more of its flow on a long or high rising main. If you need the same lift with much less volume, the JST-37SKSS also reaches 24 metres. Plan lifting equipment and a control panel rated for a 7.5 kW three-phase motor.
The pump body, impeller, shaft and motor casing are AISI 316 stainless steel. A single-channel impeller with tungsten carbide tips runs against a serrated suction cover, cutting soft and fibrous solids into smaller pieces before they leave the pump. Double mechanical seals with silicon carbide and carbon faces protect the motor, with lip seals keeping grit and abrasives away from them. The pump is supplied with 10 metres of power cable.
Features

Applications
- Large industrial effluent and process waste sumps
- High-volume leachate transfer over long rising mains
- Commercial stainless steel pumping stations
- Upgrading a JST-55SKSS installation that needs more head
This is a sewage and effluent pump, not a slurry pump. Keep sand, gravel, stones and other hard abrasive solids out of the sump, as they wear the cutting edges and seals, and check chemical compatibility with 316 stainless steel and the seal materials before pumping anything other than water-based effluent. Do not use it for flammable liquids or solvents.
