Gear metering pumps

For continuous metering of adhesives, sealants and lubricants

Gear metering pumps from DOPAG offer all the features that are required in industry today. They meter a wide range of materials, including adhesives, sealants and lubricants, continuously and with consistently high precision. They are also designed in such a way that they are extremely robust and have a high level of efficiency.

Gear metering pumps are extremely versatile. Each version is available in different forms, making them suitable for metering low to high-viscosity as well as pasty media. DOPAG gear metering pumps are suitable for use in general engineering as well as in other industries, such as aviation or wind energy.

Product properties

  • Versatile use thanks to different pump sizes, clearance classes and seal systems.
  • High-quality, hardened steel ensures operation even under difficult conditions.
  • Special coating for protection against excessive wear and to ensure a longer service life
  • Meter optionally available with gear flow meter
  • Special versions available for special applications

Seal systems

The gear metering pump can be fitted with one of four different seal systems. The seal systems have a modular design and can be replaced.

  1. URF high-pressure seal: This seal type ensures opti- mum fill level with highly viscous media by keeping the input pressure of the pump as high as possible.
  2. VCR sealing sleeve: This seal system is always used when the materials have a high proportion of fillers and when high chemical resistance is required.
  3. RSS 3-fold shaft seal: this cost-effective seal type is used to good effect in a large number of applications. It can be used to cover a wide range of requirements.
  4. MSE mechanical seal: this complex seal is particularly suitable for highly filled materials, as it is extremely low-wear.
