CEM – Electric Bronze Centrifugal Pumps inclusive of bronze head and impeller, widely used in the nautical sector to transfer and/or deliver fresh water and sea water to where a large flow rate is needed such as air conditioning, cooling and circulation

A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers.  Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impeller’s vane tips.  The action of the impeller increases the fluid’s velocity and pressure and also directs it towards the pump outlet.  The pump casing is specially designed to constrict the fluid from the pump inlet, direct it into the impeller and then slow and control the fluid before discharge
