Reversible MBR Membrane Treatment Lobe Pumps For Water Treatment Plants

Rotary lobe pumps

Rotary lobe pumps are ideally suited for use in membrane processing in wastewater treatment plants, where high flow rates and adjustable steering greatly reduce costs and efficiency, making the workflow of cleaning membranes in both directions much easier. When the medium is severely worn in the equipment,it only needs to replace the wear -resistant lining plate, which saves the cost of equipment maintenance in the later stage.The rotor uses NBR coated rubber,which also has abrasion resistance.

Operating Principles:

When pump lobes rotates, the space between 2 lobes increase, it will create a partial vacuum to transfer fluid into pump chamber, The pump shaft keeps turning, lobes will continue to create space to delivery fluid, the tolerance between lobes and chamber ensure the space is suitable to filled. When the pump chamber is fully filled, the fluid will be transfer to outlet.

Specifications:

Our pumps are available in the series of 4 series with 16 different sizes and flow rates of 1 to 3200 m³/h – high performance with smallest footprint.

Construction

• The rotary lobe pump

The powerful rotary lobe pump is designed and manufactured individual to suit your application.

• Direct drive coupling

The electric motor is coupled directly to the cylindrical pump shaft by means of a hollow shaft

• The motor

The pump is driven by an electrical parallel shaft helical gear motor.Upon request, the motor can be equipped with a frequency converter.

• The chassis

The pump is installed on a chassis made of stainless steel Thanks to the four solid-rubber tires the pumps very easy to move By slightly pressing down the pushing device. The pump can be steered very easily.

Advantages

• Compact construction,high performance in a compact design,taking less area than normal screw pump does (2/3~1/4 of which only)
• Convenient Maintenance in Place ,reduce the time of maintenance and downtime.No need to disassemble the piping or lift machine.. Replacement of wear parts in the blink of an eye, in-situ by service personnel.
• Smooth pumping action.
• Large bucket geometry and short passage through the pump provide a smooth transfer of the pumped fluid.
• Can be used for delivery mixing gas,liquid,particle , big lumps,fiber, hair, and never be blocked.
• Pump works in unrestricted reversible.
• High capacity of self-priming,maximum at 9.5 meters.
• With a Has a separated sealing cavity,keeping wet, which makes short time running idle available when lacking medium.
• Suitable for transfer different medium, casing and rotor can be customized according to client’s request.
