Low Space Requirements Convenient Maintenance Rotary Lobe Pump

 

 

Working Principle Of ACCUVON Rotary Lobe Pump

 

Rotary Lobe Pumps are self priming, valveless positive displacement pumps. The synchronized counter-rotating rotors seal towards each other.

Chambers are formed between the rotor vanes and the casing surrounding them. These chambers move from the suction to the pressure side creating a vacuum. The conveyed product in the chambers is displaced through the discharge-side casing opening. The flow direction is easily reversible by changing the direction of rotation. Therefore Rotary Lobe Pumps are best suitable for reversing operation

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.

 

Advantages Lobe Pumps

 

• Superior for highly viscous fluids
• Excellent for fluids containing compressible solids, corrosives and fine abrasives
• Suited for variable flows and viscosities, and processes with entrained air or gas
• Provide a low shear, low pulsation, and measured flow - valuable as a feeder
• Bi-directional / reversible - can do the job of two pumps
• Can run dry for limited periods of time - forgiving to busy operators Can self-prime wet and pull a suction lift up to 25 feet - low NPSH requirementSpace-saving compact design - frees up space for other activities
• Energy efficient
• Long lifespan
• Pressure-resistant
• Pump made of stainless steel
• Quick emptying of tank wagons
• Max. differential pressure for each pump: 50% of the total pressure
