11-55KW Three Lobe Pump , Petroleum Rotary Lobe Positive Displacement Pump
Double Mechanical Seal Three Lobes Rubber Lobe Pump For Oil Industry
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.

Working Principle of Rotary Lobe Pump:
The rotary lobe pumps we also called them lobe rotor pumps. They are one popular transfer pump to conveying the food, beverage, pulp and paper, chemical, pharmaceutical and so on. The rotor lobe pump relies on two synchronously rotating rotors that generate suction (vacuum) at the inlet during the rotation. Thereby sucking in the material to be conveyed. Both rotors split the rotor chamber into different spaces. Then operate in the order of 1-2-3-4. The medium is delivered to the discharge port. In this cycle, the medium (material) is continuously transported out by the source.
