Self-priming centrifugal pumps

The SPX Johnson Pump Combi system is a modular programme of single stage centrifugal pumps with a high degree of CombiPrime Self-priming centrifugal pumps CombiPrime is a series of self-priming centrifugal pumps, suited for pumping interchangeability of parts between the clean or slightly polluted liquids, with low viscosity. The pumps are available in different pump constructions. horizontal as well as in vertical construction. The pump’s self-priming ability is performed by a built-in vacuum pump, based upon the liquid ring principle. The Combi pumps cover an extensive series The most important...

Typical product applications When reliable, direct duty is of ‘prime’ importance! Shipbuilding CombiPrime pumps can handle fresh water as well as sea water, both clean and slightly contaminated. Common applications aboard ships are fire-fighting and general duty • Always ready for direct use • Available in horizontal or vertical construction • Sea water resistant version available • High pump efficiency benefit that serves well in the • Suitable for a wide span of duties narrow spaced machine rooms. • Rigid construction General industrial duty • Back/Top Pull Out principle CombiPrime pumps can...

Built-in vacuum pump The built-in vacuum pump makes it possible to pump a liquid/ air mixture or exclusively air during the suction phase. Vacuum and centrifugal pumps use the same drive mechanism, but they operate independently. This makes the CombiPrime extremely flexible, with regard to both application and installation. To maintain adequate operation of the vacuum pump a sufficient supply of service liquid to the vacuum pump is necessary. Excess service liquid is drained. There are 2 ways of doing this: • a service liquid tank, where liquid and air are being separated and vented and drained...
