Lobe Pump

Lobe pump, also named rotary lobe pump, is a type of positive displacement pump. The structure of lobe pump is similar to gear pump, but the lobes are not touch and turn each other, just almost meet.

Lobe pump without suction and discharge valves, is made up of rotating rotor and stationary pump body, changing the working space by the relative movement between the lobes and the pump body, and squeeze out the liquid by the rotating lobes, at the same time leave space on the other side, creating a low pressure, so that liquid is continuously sucked in.

Lobe pump can transfer various mediums, including but not limited to, solid, liquid and gas. It is an all-purpose pump which is widely used in various industries including beverage, food, chemical, pulp and paper.

Lobe Pump Design Featurer

● The wear-resistant plates in axial and radial direction are replaceable, and the material can be specified.

● Particular designed helical lobe, make the pump more stable, and high efficient up to 90%. The self priming head of the lobe pump are up to 9 meters. And Yaness also produce straight blade lobe with various materials, like viton, rubber, HNBR, and stainless steel, etc.

● Double support construction R&D by Yaness, with high stability and pressure resistance up to 25 bar.

● Original design of intermediate isolation chamber, ensure the gearbox not be corrode by medium, even if the seal is lost efficacy.

● Yaness adopt unique sea and structure of the lobe pump, do not to need disassemble pipe to maintain.

● Bulit-in reduction gear is optional, for save floor space and cost.

● Shafts use 4140, 42CrMoTi or Monel alloy material.

● Adopt AGMA9 high standard gear.

● Yaness lobe pump adopt NO 220 closed gear oil, overheat & low over alarm device is an optional feature that is available.

● DDS modular design, symmetrical synchronous structure, positive and negative transfer is avliable, also can CIP (clean- in-place) and SIP (steam-in-place).

Lobe Pump Principle

● Vacuum Production

With lobes do synchronized relative motion, a space produce at cavity, and vacuum production at the inlet in the meantime.

● Inhalation of Medium

Medium will be suction to cavity after vacuum production.

● Full of Cavity

Medium will full of the cavity as the pump runs.

● Discharge Medium

The medium will press out of the pump chamber as the lobes continuous movement.

Lobe Pump Advantage

● High Flow

Straight channel design, like inline pump, improved the transfer performance. It’s with higher flow than other types pumps.

Flow rang: 0.5-5000m3/h

● High Pressure

The outlet pressure of single support type’s pump can reach 8 bar, double support type’s pump are 18 bar, and multistage pump can top to 30 bar.

● High Suction Pressure

The self head of Yaness lobe pump are up to 9 meters.

● High Integration

Yaness lobe pump with bulit-in reduction gear, compact structure, great save floor space.

● High Pasing Capacity

The lobe pump with high pasing capacity can transfer various types medium, the max dia passage is 80mm.

● High Efficiency

The energy consumption of Yaness lobe pump is only 65%-85% of other positive displacement pumps.

● High Viscosity

Yaness lobe pump not only can transport low viscosity medium, but also high viscosity medium, even million CP.

● Easy to Maintain

Online quick maintenance, do not need to replace pipe.
