Variable Displacement High Pressure Industrial FPM Rubber Lobe Pump
Working Principle
Lobe pump is self-priming, valveless positive displacement pump.
Through the two parallel shafts in the synchronous gear to driven
the rotor synchronous operation, chamber form a vacuum between the
rotor vanes and casting surrounding, so that the medium was
inhaled, then displaced through the discharge-side. Pump operating
direction can be reversed by changing the direction of rotor
rotation, to be a two-way pump for reversing operation.

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:
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.
Structure features
The pump cavity design is so simple. All models of pumps retain
simple design styles. The fast -opening pump cover is opened to
provide guarantee for user maintenance personnel without
disassembling the pipeline. The driver can guarantee online repair.
Greatly reduced the stop time. Before and after, the upper and
lower wear -resistant internal lining design, comprehensively
ensure the non -wear of the pump shell and ensure long -term
durability. Such a simple maintenance characteristics reduce the
operating cost of the entire life cycle of the equipment.
