摘要： The invention relates to an eccentric screw pump which includes a stator and a rotor rotating therein as well as a drive motor for driving the rotor. The armature of the drive motor is non-rotationally linked with the rotor and rotates inside a cylindrical pot on an eccentric orbit. The torque for driving the rotor is generated by means of a stator winding.

摘要： The present invention relates to the arrangement of a stator and a spare stator. In order to avoid a permanent correction in the length of the driving shaft, the spare stator is connected to the instantaneously operated stator or is configured in a single piece. Upon occurrence of a defined amount of wear, this stator combination is merely reversed through 180° relative to the longitudinal axis or an intermediate tube is inserted so that the spare stator arrives in the rotor region.

摘要： A rotary piston pump for the delivery of liquids and for the delivery of liquids containing solids. The rotary piston pump includes a pump housing which is provided with an inlet and an outlet. The pump housing includes a lining. Disposed in the pump housing, or inside the lining, are at least two counter-rotating rotary pistons, which form pump spaces during their rotation. During the rotational movement, the rotary pistons are sealed against one another, against the pump housing and against the lining. Disposed in the pump housing and/or in the lining, in the spatial vicinity of the inlet and/or the outlet, are means with which the pulsation can be reduced or even completely prevented.

摘要： Two pairs of axial force transmitting coupling members (22, 24) and one pair of torque transmitting coupling members (26, 28) are arranged inside a housing (20). An annular cavity (42) each is formed in the housing (20) between each of the two pairs of axial force transmitting coupling members 922, 24) and the pair of torque transmitting coupling members (26, 28). A lubricant inlet opening (44) adapted to be closed opens into one of the annular cavities (42). An air outlet opening (54) is provided at the housing (20) at least approximately diametrically opposite the lubricant inlet opening (44) and communicates with the other of the two annular cavities (42) and likewise can be closed. In this manner the cavities (42) can be filled with liquid lubricant and freed of entrapped air in full measure in a short time.
