Gear pumpThey can run clockwise or counterclockwise, depending on the direction of rotation, and the entrance and exit ports change. For applications that require fixed entry and exit ports, reverse functionality will be required.

Gear pump advantages:

• Viscous fluids that cannot be handled by a centrifugal pump can be easily moved by a gear pump

• Because the pumping action is very limited, the output is very controllable. Doubling the size or speed theoretically just doubles the output

• Unlike centrifugal pumps, the output of gear pumps is completely independent of discharge pressure

Running without centrifugal force means that pump speeds can be lower, making it controllable, smooth and less destructive

• This action makes the gear pump self-priming

• The discharge pressure of the gear pump can be very high due to physical limitations such as motor power, housing strength, shaft seal, and hydraulic factors such as volumetric efficiency

• The optimum efficiency point (BEP) of the centrifugal pump is very important. This does not apply to gear pumps

Gear pumps have a lower NPSHr than centrifugal pumps, which makes them useful when the available net positive suction head (NPSHa) is small

• Gear pump is double rotating
