It can be used in the food-processing, pharmaceutical and chemical industries. It can also be used for wine, oil, syrups, volatile products such as alcohol, acetone and other solvents, or with products at temperatures close to boiling point. However, the main use of this pump is for CIP return.

​The Prolac SA pump is a self-priming pump which does not require the use of a vacuum pump or other equipment such as a foot valve or additional piping. The pump must be primed with liquid only once before starting-up. When the pump starts, it suctions the air or gas present inside the suction pipe and mixes it with the fluid inside the pump casing. The centrifugal force drives the liquid-gas mixture to the higher part of the casing. Due to the large dimensions of the casing, the fluid looses the speed and the air is expelled through the discharge pipe. Thus, the air is eliminated from the suction pipe till the liquid reaches the pump casing and then the pump operates as normal centrifugal pump. It is very important that the suctioned air can escape when running along the discharge pipe without being subject to any kind of counter-pressure. Users are strongly advised not to reduce the hydraulic power of the pump by reducing the size of the impeller or reducing the speed of the motor by means of a frequency converter since this would affect the suction power of the pump.
