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
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
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
●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
●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
●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
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
●Full of Cavity
Medium will full of the cavity as the pump
The medium will press out of the pump
chamber as the lobes continuous movement.
Lobe Pump Advantage
Straight channel design, like inline pump,
improved the transfer performance. It’s with higher flow than other types
Flow rang: 0.5-5000m3/h
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
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.
The energy consumption of Yaness lobe pump
is only 65%-85% of other positive displacement pumps.
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
Lobe Pump Application
Crude oil, heavy oil, heavy oil, sludge,
fuel oil, polymers, solid-liquid-gas heterogeneous mixtures, suspended solids,
latex, etc., oil discharge, warehouse sweeping, etc.
