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.
