High Viscosity Rotor Pump

High viscosity gear pumps achieve liquid delivery through volume changes caused by gear meshing. Their compact structure and high pressure characteristics make them the preferred equipment for high viscosity fluid processing. Magnetic seals, mechanical seals and packing seals are optional.

Product Introduction

Main features of high viscosity rotor pump

The high-viscosity rotor pump is a positive displacement pump that achieves the purpose of conveying fluid by means of the periodic conversion of multiple fixed-volume conveying units in the working chamber.

The high viscosity rotor pump has a wide range of adaptability to viscosity, and has the characteristics of low speed, high efficiency, smooth operation and convenient operation. The pump adopts advanced sealing, reliable performance and long life.

It is a special equipment for petrochemical, grease, asphalt, food, light industry industries to transport high temperature, high viscosity or high hygienic requirements.

Application characteristics of high viscosity rotor pump

1.Long service life; maintain a certain gap between the two wheels, without friction and wear

2.Wide scope of application: conveying high viscosity and high concentration media

3.Energy-saving products: novel design, low running speed and high efficiency

4.Reliable sealing: Due to the low speed, the sealing surface is not prone to high temperature, there is little wear and long service life.

5.Jacket insulation type: Jacket insulation device can be installed in the pump

High viscosity rotor pump advantage

1. Comparison with centrifugal pump

The rotor pump is a positive displacement pump, and the delivery flow rate can be controlled more accurately and can be easily made into a variable pump. The output flow of the centrifugal pump cannot be controlled and decreases with the increase of resistance; the pump has strong self-priming ability, and the centrifugal pump must be filled with liquid before rotating

2. Comparison with screw pump

Both are positive displacement pumps, so their performances are basically similar-they can stably transport high-viscosity materials, and all have higher delivery pressures. However, one of the biggest shortcomings of the screw pump determines its unsuitability in occasions with hygienic requirements-it is impossible to become a hygienic pump due to the non-streamlined surface of the screw pump and the many defects in the chamber. Or the damage of the rubber material is more likely to cause pollution to the conveyed material. In the rotor pump, due to the streamline structure of the rotor and basically no dead spots and non-metallic parts in the rotor chamber, strictly speaking, in industries with high hygienic requirements such as food, beverage and medicine, the universal pump is more suitable for application, especially The current production line is becoming more and more automated, and more and more online (in-place) cleaning (CIP) is being used, which shows the importance of selecting a rotor pump.
