CEM ABR Bronze Multi Stage Self Priming Pump

CEM ABR electric Bronze Multi-Stage Self Priming Pump made of bronze fitted with radial impellers. These pumps are widely used in the nautical sector to empty bilges, fire-fighting washing of chains and for the transfer of fuel and oil

A multi stage self priming pump with radial impellers have an incredible ability to self prime in a very short time and produce incredible positive pressure on delivery

These pumps are specifically good for use for fire fighting and emergency pump out of the bilges

Installing a strainer and non-return valve at the suction inlet recommended

The liquid-ring pump compresses its medium by rotating a vaned impeller located eccentrically within a cylindrical casing. Liquid (usually water) is fed into the pump and, by centrifugal acceleration, forms a moving cylindrical ring against the inside of the casing. This liquid ring creates a series of seals in the space between the impeller vanes, which form compression chambers. The eccentricity between the impeller’s axis of rotation and the casing geometric axis results in a cyclic variation of the volume enclosed by the vanes and the ring

Liquid-ring systems can be single- or multistage. Typically a multistage pump will have up to two compression stages on a common shaft. In vacuum service, the attainable pressure reduction is limited by the vapour pressure of the ring-liquid. As the generated vacuum approaches the vapour pressure of the ring-liquid, the increasing volume of vapor released from the ring-liquid diminishes the remaining vacuum capacity. The efficiency of the system declines as a result
