Hydraulic Diaphragm Metering Pump Hydro/ 2

Capacity range of single pump: 3 – 72 l/h, 100 – 25 bar

As an extremely robust hydraulic diaphragm metering pump, the Hydro/ 2 meets the most exacting safety requirements. Its modular construction, with either one or two dosing heads, 4 gear ratios, 2 dosing head sizes and 3 dosing head materials, offers a very high degree of flexibility in terms of areas of application.

Product description

For flexible metering with excellent process reliability in the medium pressure range.

The Hydro/ 2 hydraulic diaphragm metering pump (HP2a) together with the Hydro/ 3 and Hydro/ 4 pumps represent an integrated product range with stroke lengths of 15 and/or 20 mm. This covers the capacity range from 3 to 1,450 l/h at 100 – 7 bar. A wide range of drive versions is available, including some for use in Exe and Exde areas with ATEX certification. The Hydro product range is designed to comply with API 675 among others.

Your benefits

Excellent process safety and reliability:

  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system
  • Integral hydraulic relief valve
  • Metering reproducibility is better than ± 1% within the 20-100% stroke volume range under defined conditions and with proper installation

Excellent flexibility:

  • The modular construction with single and double head versions permits a wide range of applications, with the double head designs being operated in push-pull mode
  • It is possible to combine up to 5 metering units, even with different pump capacities, in multiple pump systems
  • 5 different gear ratios are available

Field of application

  • Oil and gas industry
  • Volume-proportional metering of chemicals/additives in the treatment of boiler feed water
  • Metering of reactants and catalysts in the chemical industry
  • Level-dependent metering of auxiliary agents in industrial production engineering, for instance hot wax metering in the production of adhesive strips

    Technical Details
