Abstract

The present invention relates to a pump assembly of displacement-type, comprising a pump housing (1) having a pump housing chamber (14) with inlet and outlet conduits (13, 17) for the pump medium, pump rotors (19) in said pump housing chamber (2), which interact with each other, said assembly also comprising two electrical motors, one for each pump rotor, each one with a motor rotor, enclosed in the pump housing and designed to drive the respective pump rotor, each one of said motor rotors and the corresponding pump rotor forming a motor rotor-pump rotor-unit (18), integrated in the pump housing. In accordance with the invention each one of said motor rotor-pump rotor-units is provided with the rotary part (25) of a unit designed to detect the angular position and the rotary speed of the motor rotor-pump rotor-unit, whereas the other part (33) of said unit is stationarily mounted. Also, a common electronic unit (26) for the two detection units is mounted, designed to control said motors and then also said pump rotors angle-synchronously, dependent on said detection.
