Low Starting Torque Rubber Lobe Pump With Various Rotor Options
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.

Design and Materials:
- Pump casing: one-piece Block casing with protective liner plates at
both faces.
- Bearings: one side double bearings, oil bath in block-casing,
lateral drain plug
- Rotors: entirely NBR - coated, core not product wetted
- Rotor-form: dual lobe rotors, entirely elastomer coated
- Shafts: not wetted by pumped fluid, but oil lubricated Shaft
- Sealing: maintenance free single acting mechanical seals with
common oil quench, seal faces SISIC / SISIC; Seals easily
replaceable through pump casing.
- Seal monitoring: oil-filled intermediate chamber, integrated in the
pump casing, with lateral drain plug, as Quench, for seal
monitoring and for lubricating the shaft-rotor-connection, without
external fluid reservoir, without pressurization.
- Pump: 2-component-PUR-coat
- Drive: Manufacturers standard
- Maintenance: MIP™, Maintenance in Place, through quick release
cover opening, with 4 rings nuts and O-ring-seal, without
disassembling the pump and/or pipes.
Rotor types
Different forms of rotor design meets the diverse needs of users,
and the materials of the rotor are also diverse, such as NBR
rubber, EPDM rubber, FPM rubber, FFKM rubber, PU, Stainless steel,
copper, PTFE, etc.
Advantages
Good suction property, but depended from the pump speed.
Easier installation of pump-systems, through the suction property
Stainless steel rotors are available for all pumps, and some models
offer rotors from PTFE.
Starting Torque Low, as all rotating elements are guided in
anti-friction bearings. Star-Delta-Start is possible with
three-phase-motors.
