Rotory lobe Pump

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´╝îmedium(material)is transpor-ted continuously.

Special Structure
Rotor Pump Configuration

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.


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 do not 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 will not be any damage in theory, so the rotor pump can work at temperature of 220 degree celsius in all environments.


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.
