The rotary pump may be classified as a volume pump and is used for the transportation of various fluids and generating necessary pressure. The rotary pump comprises the following main elements: pump housing (1), geared rotors (3) located on shafts (2) mounted into the housing and partitions (4). In order to decrease vibration and prolong useful utilisation period the pump housing comprises at least two pairs of rotors separated by partitions. The rotors located in separate chambers of the driving shaft are mounted at certain angles. The rotors mounted on the driven shaft can freely rotate regarding each other.
