Pneumatic Sump Pump — IMPA 591635-591637

This pneumatic submersible sump pump is engineered for emergency dewatering of ballast tanks, bilge wells, and cargo holds aboard cargo ships, container vessels, tankers, and offshore support vessels. It is particularly valued where electrical equipment poses an ignition or explosion risk, making it the preferred choice for tankers and gas carriers. The pump is also widely used for draining cargo holds during and after washing procedures, ensuring safe and efficient water removal in hazardous environments.

Designed as a two-part integrated unit, it combines a tangential intake blade-type pneumatic motor with a high-efficiency spiral vortex chamber pump section. The tangential compression at the cylinder center reduces intake airflow resistance and pressure loss, while the balanced velocity energy design minimizes uneven blade wear at both ends, extending service life. Optimized structural parameters and intake/exhaust positioning increase the expansion working chamber, significantly boosting shaft power. The motor and pump are matched to improve head performance. The full series covers IMPA codes 591635-591637 (3 variants), each available and priced individually.
