37kW QXN20-230/7-37 Deep Well Submersible Pump 230m | For Quarry Shaft Dewatering

The QXN series is a slim, multistage submersible pump for jobs where space is tight but pressure must be high. Its radial dimensions are small enough to drop into narrow well casings, cramped pits and crowded pipe runs, while stacked centrifugal impellers build heads of over 200 metres — several times that of a standard submersible. Because the motor is cooled by an internal jacket rather than the surrounding water, the pump keeps running with the motor partly or fully above the water line. A bottom-suction inlet sits flat against the floor, draining a pit to the last centimetres instead of leaving a puddle behind. Typical duties: deep well lifting, mine shaft drainage, high-rise pressure boosting, orchard irrigation and ship bilge work.
