The technology of manufacturing the rotary lobe pump 

Rotary lobe pumps are self-priming, valveless and rotating positive displacement pumps with two rotary lobes running in a mesh. The rotation of the rotors creates a vacuum on the suction side, which draws in the pumped medium.

The rotors displace the medium into the pressure area. Two to six-room fillings are substituted per rotation, depending on the number of Rotorrotor,Rotors,rotorsrotor blades. This enables dosing proportional to rotation speed. Due to the unique spatial separation between pump and gear chamber, TORNADO® rotary lobe pumps also offer you maximum operational reliability. With the best technology for manufacturing rotary lobe pumps, you can pump both low and high viscosity media. Due to the significant free ball passage and the low speeds, they are insensitive to blockages, clogging and foreign bodies. Varying solids contents have just as little influence on the flow rate as pressure changes. This enables continuous and powerful self-priming pump.
