An End Suction Pump also known as a transfer pump is a type of centrifugal pump where the suction is axial and the discharge is at 90 degrees to the suction. Many designs have a centre line discharge to comply with worldwide or regional standards.

There are two types of end-suction centrifugal pumps: long coupled (separate coupling & motor) and close coupled (motor and pump are housed together) known as Monoblocs. A dual volute is usually found on larger end-suction pumps to reduce the force acting on the impeller, motor, shaft, and bearings

End suction pumps are mostly single stage pumps and the most common materials used are cast iron, bronze and stainless steel. The end suction pump is typically designed as a back pull-out pump with a spacer coupling that facilitates maintenance without affecting the alignment. This saves space and eliminates the need to align motors.

Frequently Asked Questions

What are the common applications of end suction pumps?

Some common applications of end suction pumps are the transfer or circulation of low-velocity liquids, solids handling, slurries, and chemicals.

What are the best piping practices for end suction pumps?

Air pockets should be eliminated by arranging the piping in such a way as to allow easy flow into the suction. Otherwise, they should be equipped with suction diffusers.
