NBR Rubber Screw Lobe Rotor Pump , Sewage Positive Displacement Water Lobe Pump
Resistant To Solids Positive Displacement Rotary Lobe Pump
ACCUVON Rotary Lobe Pump
Rotary Lobe Pumps are self-priming, valve less, positive displacement pumps. With speed-proportional flow, they continuously deliver trouble-free pumping of liquids of various consistencies and multiphase mixtures. They are compact and operate with low shear and low pulsation.

Components
1. Bearing and Timing Gear
The timing gear is in a separately sealed construction element. The high quality and robustly designed gear wheel ensure a precise transmission and long service life.
2. Intermediate Chamber
The fluid-filled and separately-sealed intermediate chamber divides the timing gear from the wetted pump chamber. It protects the gear from penetration of conveying liquid and the pump chamber from contact with gear oil. It is also the seal quench.
3. BLOCK-Pump casing
The wetted pump casing is made from a single block - casing with low tolerances. It is available from high quality gray cast iron, ductile iron or stainless steel. A quick release cover fitted with just four ring nuts closes the casing. This allows an easy and quick access to the inner parts of the pump.
4. Axial and radial casing protection liners
Axial casing protection liners are fitted as standard at both face ends of the wetted pump casing. The liners are made from hard metal, hardened steel or specially treated stainless steel. The front side clamped in liner between the casing face and the quick release cover as well as the screwed-in rear plate is easily accessible because of the quick release cover.
5. Shaft Seals
These maintenance free shaft seals are available from different materials, adapted to the pumped liquid. Also, the elastomers are selected individually for each application. Special designs such as double acting mechanical seals are available upon request.
6. Rotors
The rotors are adopted to each individual application. Beside different metals there are different elastomers, plastics or special materials available. The building kit system ensures that almost all rotors can be retro fitted to previously supplied pumps.
7. Quick Release Cover
One side bearings as a matter of principle allows the quick release cover with the best access possible to all parts being wetted and subject to wear. All of these parts can be easily inspected and simply be replaced if needed.
8. Non-wetted Shafts
The self-sealing design of the entirely elastomer coated rotors prevents any contact of the pumped liquid with the shafts. With all other rotors this is ensured by separate O-rings.
