Reserve Circulation Pump, Pressure : Atmospheric To 15 kg/cm2

Type HR reverse circulation pumps are designed for fluids & chemicals with relatively high vapour pressure, low specific gravity, low specific heat liquids. Liquids with steep vapor pressure curves may vaporize on picking up the motor heat and result in cavitations conditions The circulationpumping 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 vapor zone in the suction tank, through the reverse circulation line.
