CEM – Jet pumps

Self priming centrifugal electric Jet pumps with a closed impeller, featuring a high suction capacity, widely used to deliver pressurized water to onboard appliances such as showers, kitchens, galleys, washbasins, toilets, for air-conditioning units, fire fighting, washing of decks and chains

Automatic operation of jet pumps is achieved by equipping the pumps with small or medium-sized surge tanks

At the jet, the increase in water velocity creates the partial vacuum that draws standing well water into the second pipe and then back into the pump and plumbing system. Deep-well jet pumps use both the suction at the jet to bring water into the system and pressure applied by the impeller to lift the water

This pump type has a very good ability to perform well in high pressure environments, this is shown with the curve being a gentle incline. Combined with an accumulator and pressure switch this is a tried and tested pump for use in water pressure systems
