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： A method and a device for fixing and synchronising rotary pistons in a rotary piston pump are disclosed. The rotary pistons are introduced into the pump space of the rotary piston pump. A shaft stub of each rotary piston is then pushed through a pump rear wall onto a driveshaft provided for the respective rotary piston. The rotary pistons are aligned and synchronised in the pump space by means of a template, the template being fixed detachably to a pump housing. The shaft stubs of the respective rotary piston are connected, after the synchronisation, in each case by means of a clamping device in a friction-locked manner to the respective driveshaft, outside the pump space.

摘要： An eccentric screw-type pump has a pump section with a tubular pump casing, a stator cladding and a pump cavity (30) configured in correspondence with a double-thread or multi-thread screw. A screw-type rotor is connected to a driving shaft via a flexible shaft. The flexible shaft is connected at its two ends via rigid coupler elements to the rotor and the driving shaft, and is surrounded by a preloaded coaxially disposed screw.
