Resistant Wear NBR Rotor Positive Displacement With Gooseneck Flange
Accuvon rotary lobe pumps
Accuvon rotary lobe pumps convey different fluids, whether with low or high viscosity, containing solids or pure, chemically aggressive or up to a temperature of 200°C. Due to the large selection of different materials, rotors and sealing systems, the pumps can be customized.
Our pumps are available in the series of 4 series with 16 different sizes andflow rates of 1 to 3200 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 over pressure on the discharge side of the pump. The flow direction can easily be reversed by changing the direction of rotation.

Construction
1. The quick-release cover
Access to all wetted parts by simply loosening four ring nuts – maintenance without removal of pipe or drive systems.
2. The rotors
Large selection of high-quality rotors for almost pulsation-free pumping of the medium.
3. The casing protection
Depending on its size, the BLUEline pump is available with and completely without protection plates and liners. When pumping abrasive media containing solids, the protection plates and liners protect the pump casing from wear and can be replaced in a matter of minutes.
4. The intermediate chamberand shaft seal
The large-volume quench chamber is oil-filled and ensures the highest degree of safety. The ideal mechanical seal is selected depending on the medium.
5. The carrier and timing gear
The high-quality and maintenancefree carrier and timing gear guarantees a smooth and even operation of the rotors. The result is a long service life of the pump.
