Operation Principle:
Rotor pump is also named rotary lobe epump, three-lobe pump, sole
pump,etc. When the 2 simultaneous reverse rotating rotors(with 2-4
gears)revolve, it produces suction force at the inlet(vacuum),which
intakes the material delivered.The 2 rotors divide the rotor
housing into many smaller parts and revo-Ive in the sequence of
a→b→c→d.When it revolves to position a,only housing I is filled
with medium;when it revolves to position b,housing B encloses part
of the medium,when it goes to position c,housing A encloses
medium,and finally it goes to position d,then housing A,B and II
are interlinked and the medium is transported to the outlet.As this
process is repeated,medium(material)is transpor-ted
continuously.
ROTOR PUMP STRUCTURE:Special Structure:
Butterfly rotor pump:
with butterfly rotor,it is superior to other rotor pump when
transferring material with high viscosity and largerpowder and
effectively transports extremely stiff material.
Single butterfly curved rotor pump(powder rotor
pump):
this pump series are specially design to transport material with
larger powder.Its unique shape and curve makes it more
outstanding compared to other pumps in delivering material
withlarger powders.It effectively prevents powders from
clashing,which is the top choice of pumps transferring material
with powders.
Main parameter:
Note: the flow in tile table refers to the
aata tested taking water as the medium.
Adopts stepless speed regulator or frequency transformer to adjust
the speed,with speed adjustable in 200—900rpm.
The motor power should be increased when delivering high viscosity
liquid
For mediums that flow slowly,pumps of matched flow rate should be
equipped in the inlet.

Main Application Characteristices:
High Viscosity Material Feeding
Pump:
With the characteristics of volume pump, low rotation speed, high
output torque, high temperature resisting, the rotor pump plays a
very important role in feeding high viscosity, high temperature
material fields. It has a unique operation principle matching and
can be sued matching a powerful driving system, so that the rotor
pump can output a powerful driving moment at a low speed and ensure
material feeding consistently, without stagnancy, and also can
ensure that the material performance in the process of material
feeding not be damaged. The medium viscosity can reach 1,000,000CP
fed by this pump.
Thin medium feeding pump:
When rotor pump feeding special thin medium, especially feeding
thin medium without pulse as required, a big performance advantage
can be shown. If the viscosity of the fed medium descends and
leakage increases, driving system matched with rotor pump can
improve the rotation speed and ensure the invariance of the output
flux.
Sanitary Feeding
Pump:
All parts contacting with material are made of stainless steel
which is conforming to sanitary standard, applicable to sanitary
and erosion resisting place in fields of food, drinks, pharmacy,
chemical industry, etc.
Water cleaning mechanical seal:
Mechanical seal configuration with water cleaning function can be
provided, preventing equipment normal operation on the end surface
of the mechanical seal from coagulation during feeding high
viscosity material, and the service life mechanical seal in bad
environment can be ensured.
Almost Have No Consumable Parts:
There don’t have any damage on the part during the rotor pump is
operating (except mechanical seal), all parts contacting with
material is made of stainless steel. A pair of rotors run
synchronically during operating in a space with each other, no
contact, there won’t be any damage in theory, so the rotor pump can
work at temperature of 220℃ in all environments.
Choosing the driving system:
Motor+mechanical abrasive stepless speed regulator:the speed
regulator changes the speed by manual adjustment,which is
safe,reliable and infinitive flow adjustment.But
thenon-automatic adjustment is also troublesome. Speed regulating
should be done in operation not in shutoff state.Pleasereferto
manufacturer instruction for maintenance and service.
Motor+fixed relative ratio speed reducer:the driving is easy with
cons-tant rotary speed of the rotor,which also leads to
nonadjustablity of flow.
Frequency transformed motor+frequency transformer:it realizes
both automatic adjusting and infinitive adjustment of flow.It is
highly automatic and has large torque in low speed.But the
frequency transformer is expensive.ase refer to manufacturer
instruction for maintenance and service.
