Abstract

The pump has a main stage (1) and a second booster stage (2). The main pump is selffregulating. The booster pump has a rotor mounted on the main pump shaft. The booster pump consists of vanes (26) mounted radially in the rotor (24). The rotor is eccentric in the casing (10) and the pump has a discharge passage (37) which connects with the inlet of the main pump (13). The main pump has a control piston and a compensating piston.
