Heat Jacketed Rotary Lobe Pump With Stepless Speed Regulator 3RP Series

Product Specification

3RP series speed adjustable stepless speed regulator heat jacketed rotary lobe pump

Brief introduction

3RP rotor lobe pumps are rotary positive displacement pumps, developed after decades of research and design. The manufacture engineering and accuracy has come up to advanced world level.

How It Works

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
