Rotary Lobe Pump


Rotary Lobe Pumps are self-priming , valveless, positive displacement pumps. The even rotation of the rotor pair creates a vacuum on the priming side of the pump, which can be defined by the direction of rotation of the drive. This vacuum draws the liquid into the pump chamber. With further rotation, the pumped medium is conveyed past the pump wall into the pressure area. Up to six chamber charges are displaced with each drive rotation– depending on the rotor type. When the rotor is at a standstill, the pump seals off almost completely.


The low number and compact nature of the individual components will astonish anyone that has disassembled a rotary lobe pump. The different sizes of the housings and rotors are manufactured in a single piece construction, quite different from the high number of components normally found in comparable pumps. The result of course are robust and compact rotary lobe pumps, which are known for quiet, safe and reliable operation, long operational life and for ease of maintenance. The replacement of wear parts can be managed, in-situ, by service personnel in the blink of an eye without the removal of pipe systems o rdrive units. Rotary lobe pumps are universally mountable and are suited for many different types of installation. For example, electric, combustion and hydraulic drives are used.
