PUMP CONSTITUENTS
PUMP WORKING
1
This is a Vane Type Pump driven by an electric motor. A slotted rotor (carrying five vanes) is eccentrically supported in a cycloidal housing
forming a crescent-shaped cavity.
When the motor starts, the rotor, being attached to the armature shaft with a key, starts rotating. As the shaft reaches 2600 RPM, centrifugal
force & hydraulic pressure push the vanes to the walls of the housing. It generates sufficient suction to draw fluid into the pumping chamber
through inlet port. Fluid enters the pockets created by vanes, rotor and cover plate.
As the rotor continues to rotate, the vanes sweep the fluid to the opposite side of the crescent where it is squeezed through outlet port into
the delivery hose.
