Working Principle

1.Before startup, the float is positioned at the lowest point of the pump body, with the drive gas inlet closed and the exhaust outlet open.

2.Upon startup, condensate from the steam?using equipment enters the collection tank and opens the inlet check valve by gravity. System backpressure keeps the outlet check valve closed, and the float begins to rise as condensate fills the pump.

3.As more condensate enters, the float continues to rise, increasing spring tension through a linkage. When the spring reaches its upper extension point, the tension is released suddenly, moving the linkage upward to open the drive gas inlet and simultaneously close the exhaust outlet.

4.Drive steam, air, or other gas enters the pump through the inlet valve, raising internal pressure, closing the inlet check valve, and forcing condensate to open the outlet check valve for discharge to the recovery tank via the condensate return line.

5.As condensate is discharged, the float descends, increasing spring tension through the linkage. When the spring reaches its lower extension point, the linkage moves downward to close the drive gas inlet and open the exhaust outlet.

With the exhaust outlet open, gas in the pump flows to the collection tank, reducing internal pressure. System backpressure then closes the outlet check valve, and fresh condensate opens the inlet check valve by gravity to re?enter the pump, beginning a new cycle.

Performance Features

1.Improved Production Efficiency – Condensate removal and recovery help enhance production efficiency and product quality, conserve energy, reduce water treatment costs, and optimize steam heat utilization.

2.Prevention of Heat Exchanger "Stagnation" – Stable temperature control improves heating efficiency. Water hammer is minimized, reducing equipment damage risk and enhancing reliability. Accumulated condensate is effectively managed to prevent cavitation.

3.Cavitation?Free Operation – Capable of recovering high?temperature condensate (up to 185°C) without cavitation. Low suction head requirement enables use with low?positioned equipment. Common issues found in centrifugal pumps—seal, bearing, and impeller failures—are effectively avoided.

4.No Electrical Power Required – Ideal for hazardous or power?limited locations. Mechanical operation is reliable, with no complex controls needed. Installation and maintenance are quick and straightforward, with low upkeep costs.
