CombiPrime is a series of self-priming centrifugal pumps, suited for pumping clean or slightly polluted liquids, with low viscosity. The pumps are available in 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 most important characteristic of the CombiPrime is the built-in vacuum pump. This makes it possible to pump a liquid/air mixture or exclusively air during the suction phase. The built-in vacuum pump is based on the liquid ring principle.
The CombiPrime is used when handling vapour, aerated liquids or air during the priming stage. The availability of several material options enables corrosive media to be pumped. Applications: bilge and ballast pumps in shipping, fire extinguishing, sprinkler sets.
Maintenance is simplified because of the applied ‘Back Pull Out’-principle for the horizontal and ‘Top Pull Out’-principle for the vertical construction.
