Hydraulic Diaphragm Metering Pump Hydro/ 2

Capacity range of single head 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, represents 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 power end versions is available for use in areas at risk from explosion 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

    • Stroke length: 15 mm, Rod force: 2,000 N
    • Stroke volume adjustment range: 0 – 100%
    • Stroke volume adjustment: manually by scaled rotary dial (optionally with electric actuator or control drive)
    • Metering reproducibility is better than ± 1% in the 20 to 100% stroke volume range under defined conditions and with correct installation
    • PTFE multi-layer diaphragm with electrical diaphragm rupture warning / signalling system via a contact
    • Integrated hydraulic relief and bleed valve
    • Wetted materials: PVDF, PTFE+25% carbon, stainless steel 1.4571, Hastelloy C.
    • A wide range of power end versions is available: Three-phase or 1-phase AC motor, motors for use in areas at risk from explosion, different flange designs for use of customer-specific motors
    • Degree of protection: IP 55
    • Design in compliance with API 675  see page →

    Motor data sheets can be requested for more information. Versions 265/460V - 60Hz, special motors or special motor flanges are available on request.

    The motors are designed in accordance with the Eco Design Directive 2009/125/EC.

    Information for use in areas at risk from explosion

    Only use pumps with the appropriate labelling in line with the ATEX Directive 2014/34/EC in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label correspond to or are superior to the conditions prevalent in the intended application.
