ROTARY LOBE PUMP
The pumps offer high performance with low space requirements and minimum energy
consumption. Our product reliability and durability guarantee market leading system safety, giving you peace of mind. Rotary lobe pumps convey different fluids, whether low or high viscosity, clean or containing solids, chemically aggressive or up to a temperature of 392 °F (200 °C). Due to the large selection of different materials, rotors and sealing systems, the pumps can be customized. Our pumps are available in 24 different sizes and flow rates of 1–7,000 gpm (1–1,600 m³/h) – high performance with smallest footprint.
OPERATING PRINCIPLE
Rotary lobe pumps are not sensitive to dry running and are self-priming positive displacement pumps. The synchronized rotation of the rotor pair and the increasing suction chamber create a vacuum on the priming side of the pump. This vacuum draws the liquid into the pump chamber. The pumped medium is conveyed past the pump wall into the pressure area by the rotors. The synchronized rotation of the rotor pair and the decreasing pressure chamber create an overpressure on the discharge side of the pump. The flow direction can easily be reversed by changing the direction of rotation.
OUTSTANDING RANGE OF MATERIAL
The correct selection of material is important for the durability of a pump. For this reason, all components of our pumps are available in different materials. Using a modular principle, the most resistant material suitable for the relevant pumped medium is selected for each
pump component, from the o-rings to the pump casing.
VARIETY OF ROTORS
We offer a range of linear and screw rotors differentiated by geometry and material. Whether made of NBR, EPDM, FKM, stainless steel, steel or another material, we offer a suitable rotor for your application. Only single-piece rotors are used quality down to the last detail.

Applications
Rotary lobe pumps are ideal for applications involving slurries, or liquids with solids in suspension. The capability of these pumps to easily pass solids gently and without damage makes them an ideal candidate for water/sewage/effluent treatment applications, along with general industrial applications. Pumps are not only robust and designed for difficult applications, but are easy to maintain and can often be serviced in situ without removing connected pipe work. Slurries, Mud, Oils, Heavy oils and crude oils loading and unloading application are frequently using lobe pumps.
