High Efficiency Wear-Resistant NBR Rotary Lobe Pumps With 18.5kw
Motor
Rotary lobe pumps
Accuvon rotary lobe pumps can effectively transport sludge with a
solid content of 3-6% for a long time.We add axial wear-resistant
protective lining plates to the pump to effectively protect the
pump shell.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 Principle
Rotary lobe pumps are not sensitive to dry running and are
self-priming positive displacement pumps. The synchronized rotation
of the rotor pair and the increasing suction chamber
create a vacuum on the priming side of the pump. This vacuum draws
the liquid into the pump chamber. The pumped medium is conveyed
past the pump wall into the pressure area by the
rotors. The synchronized rotation of the rotor pair and the
decreasing pressure chamber create an over pressure on the
discharge side of the pump. The flow direction can easily be
reversed by changing the direction of rotation.

Construction
The powerful rotary lobe pump is designed and manufactured
individual to suit your application.
The electric motor is coupled directly to the cylindrical pump
shaft by means of a hollow shaft
The pump is driven by an electrical parallel shaft helical gear
motor.Upon request, the motor can be equipped with a frequency
converter.
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
ACCUVON rotary lobe pumps are designed based on the exploration of
more than 3,000 fluids in various industries. They are particularly
pumping for high viscosity, high solids, sanitary and corrosive
fluids. The pumps are widely used and have long service life
benefits from the below features
- 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.
