3RP series high viscosity explosion proof motor stainless steel
rotary lobe pump for transfer food liquid
Rotor pump is also named rotary lobe pump, 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.

Product feature:
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 used 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.
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
It doesn'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, it won’t be any damage in theory, the rotor pump can work
at temperature of 220℃ in all environments.
Rotor Introduce:
Single impeller: used to transfer medium with a little large grains
because this impeller is not easy to damage grains. The shortage if
high impulse, low pressure, small capacity, so seldom using.
Double impeller: used to transfer medium with middle or small
grains, with low damage rate and low impulse, the capacity is
smaller than tr-impeller.
Tri-impeller: this is commonly type, the capacity and performance
is better than other rotors. The shortage is high requirement to
medium because its easy to damage grain medium.
Multi-impeller: when impeller quantity beyond three, the capacity
will decrease when impeller increase. Multi-impeller has high
stability while using, but easy to damage grain medium
