that impeller will always be immersed in water. This is a compact design which saves space and makes the installation easy. An air ejector is connected to the pumps suction side. Automatic start and stop of the air ejector makes the pump self priming. The pump is manufactured from stainless steel with seawater resistant bronze impeller.

gal pumps: radial flow, mixed flow and axial flow based on the direction the fluid enters the inlet (eye) of the impeller, see figure 1.2. Radial and mixed flow pumps are either single or double suction designs. A centrifugal pump produces head, H as a function of the rate of fluid flow, Q through the impeller, see figure 1.3. Head

Problem Solving - Centrifugal Pumps

Centrifugal pumps should never be allowed to operate in the wrong direction of rotation. If the pump is not fitted with an impeller screw the impeller may unscrew from the shaft making contact with the casing, thereby causing seizure. To ensure correct direction of rotation the motor can be started and stopped momentarily to check the
