Rotary lobe pumps are positive-displacement type pumps that use two or more lobes rotating around parallel shafts in the pump's body to move liquids. They are widely used in the hygienic processing industries, including food & beverage processing and biopharmaceutical manufacturing.Vane Pumps are ideal for low-viscosity and non-lubricating liquids. Sliding Vane Pumps are used for vacuum services. Lobe Pumps are used in food and beverage processing. Lobe Pumps can handle both low and high viscosity fluids.Rotary lobe pumps are designed so the rotor does not touch any part of the housing. This allows the pump to run dry with only a small increase in temperature and without the risk of damage to any part of the unit.Gear pumps are characterized by close internal clearances and tight gear meshing action. Lobes pump product similarly to external gear pumps, but the lobes do not contact and can be made from stainless steel, which makes them excellent candidates for food applications.The pumping action of the rotary lobe pump principle is generated by the counter rotation of two pumping elements (rotors) within a chamber (rotor case). As the rotors pass the suction port, the cavity generated increases creating a pressure decrease, which induces the pumped medium to flow into the rotor case.Piston pumps are used for water and oil hydraulics, industrial processing equipment, high pressure cleaning and the pumping of liquids.A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet.Rotary lobe pumps are self-priming, i.e. they can build up pressure to such a high level without external help that the medium can be sucked in independently.
