High Viscosity External Gear Metering Pumps

The high-viscosity external gear metering pump is an industrial-grade precision conveying and metering device specifically developed for various high-viscosity and viscous media. It utilizes an external gear transmission structure and is suitable for the constant-volume conveying and precise metering of high-viscosity media such as paraffin wax, resins, adhesives, greases, pastes, and heavy oils. Optional electric heating/thermal oil insulation modules are available to perfectly match the conveying needs of high-viscosity and easily solidified media like paraffin wax. Widely used in chemical, petrochemical, daily chemical, coatings, and rubber and plastics industries for production line feeding, proportioning, and quantitative discharge, it boasts core advantages such as high metering accuracy, strong pressure resistance, and stable, leak-free operation, making it a core conveying and metering equipment for automated production of high-viscosity media.

 

 

Advantages of high viscosity external gear metering pumps

The high viscosity external gear pump is a high performance metering pump with the following advantages:

1. High viscosity external gear pump has high hydraulic performance.

    Its structure is compact, the pump body has good rigidity, can withstand large pressure, and has stable flow rate and no pulsation.

2. The high-viscosity external gear pump has high volumetric efficiency, small power loss, and certain energy-saving effect.

3. Simple manufacturing process and long service life.

    The high viscosity external gear pump consists of two meshing gears with simple structure and high processing accuracy.

    The gears are made of wear-resistant materials, making the performance more stable and durable.

Application for the high viscosity external gear metering pumps

High viscosity external gear pumps have a positive effect on improving production efficiency and production quality.

It is widely used in petroleum, chemical, pharmaceutical and other industries, and its performance is more significant under corrosion resistance, high viscosity and high pressure conditions.
