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．
