2.1 Pump description
The CombiPrime V is a range of vertical self-priming centrifugal pumps. Hydraulic
application area complies with EN 733 (DIN 24255) (with the exception of 250B-315).
The flange dimensions, bolt circle and number of holes comply with ISO 7005 ND 10.
The CombiPrime V is characterized by the built-in vacuum pump. Thus it is possible to
pump fluids mixed with air (gas) or only air during the suction phase. The built-in vacuum
pump is based on the liquid ring principle. The pump is driven by a standard IEC flange
motor. The power is transmitted through a flexible coupling. Because of their modular lay-
out, constructional components are widely interchangeable, also with other pump types
of the Combi system.
