MU-Series
Mutiny®
Steam or air-operated condensate return pump that recovers hot condensate without an electrical drive.
Product overview
A displacement pump driven by steam or compressed air, used to move hot condensate from a low-level collection point back into a pressurised return line. Because it has no electrical drive and no mechanical seal, it handles condensate at temperatures that would cavitate a centrifugal pump.
The problem it solves
Hot condensate at or near saturation cavitates electrically driven pumps, and flash at the pump suction destroys seals. The usual workaround — cooling the condensate or dumping it to drain — throws away recoverable energy and treated water.
Working principle
Condensate fills the pump body under gravity until a float trips the inlet motive valve. Steam or air pressure admitted above the liquid displaces it into the return line against backpressure. When the body empties, the float reverses the mechanism, the motive supply closes, the exhaust opens and the cycle repeats.
Applications
- Low-level condensate collection points and pits
- Pressurised condensate return against backpressure
- Hazardous areas where an electrical drive is undesirable
- Recovery of near-saturation condensate for boiler feed
