Reverse Circulation Pump

The pumps are designed for fluids with relatively high vapour pressure, low specific gravity, low specific heat liquids. Liquids with steep vapour pressure curves may vapourize on picking up the motor heat and result in cavitation conditions & vapour locking. The circulation/pumping fluid is passed from the casing volute chamber into the rotor chamber through the front bearing housing. After being extracted from the outlet of rear bearing housing, the liquid is returned to vapour zone in the suction tank, through the reverse circulation line.

Suitable for volatile liquids, liquefied gases & refrigerants such as ammonia and synthetic fluro and chloro hydro carbons.
