CHECK PUMP ROTATION

PRINCIPLE OF OPERATION

-

The pumps are of the positive displacement rotary type with lobed rotors. The volume at

the inlet increases when the rotors rotate and the product is drawn into the pump. It is

then transported in the space between the lobes and the periphery of the pump housing to

the discharge side. The volume between the rotors is reduced here and the product is

forced out through the outlet.

DIRECTION OF ROTATION

-

The direction of flow is dictated by the direction of rotation of the drive shaft. Reversing

the direction of rotation will reverse the flow direction. Top and bottom shaft drive.
