Rotary Lobe Pumps / Solids-Resistant / Self-Priming /
Pulsation-Free
Accuvon is a specialist in rotary lobe pumps. We offer
solids-resistant rotary lobe pumps with flow rates of 1 – 4,000
m³/h and a large selection of equipment and additional parts. The
pumps can be used as mobile, stationary or submerged versions.
OPERATING PRINCIPLE
Accuvon rotary lobe pumps are self-priming, valveless, positive
displacement pumps. The synchronized rotation of the rotor pair
creates a vacuum on the priming side of the pump. This vacuum draws
the liquid into the pump chamber. The medium is pumped into the
pressure area due to the rotation of the rotors. If the direction
of rotation is changed, the flow is reversed.
CONSTRUCTION
1 . The quick-release cover
Access to all wetted parts by simply loosening four ring nuts.
2 . The rotors
Large selection of high-quality rotors for almost pulsation-free
pumping of the medium.
3 . The casing protection
The casing liners and casing protection plates protect the pump
casing from wear and can be replaced in a matter of minutes.
4 . The intermediate chamber and 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 maintenance-free carrier and timing gear
guarantees a smooth and even operation of the rotors. The result is
a long service life of the pump
