In end-suction centrifugal pumps, the suction line and the motor are parallel, and the water enters from the impeller's end. It is not possible to use bearings on both sides of the wheel because water only enters from one side. The pump cannot be used in high-flow applications because the bearing support is typically provided by the motor.

The primary advantage of end-suction pumps is their low investment cost. If certain pressure and flow requirements are met, this type of pump is preferred. If the pump is powered by diesel, the engine can be placed parallel to and close to the wall, taking up less overall room space.

This type of pump's disadvantage is that any maintenance on the pump requires the removal of the impeller. The engine must be disassembled in order to accomplish this. End-suction pumps are consequently more difficult to maintain.
