Hydraulic diaphragm metering pump Hydro/ 3 API 675

Capacity range of single head pump: 15 – 201 l/h; 100 – 10 bar

The Hydro/ 3 API 675 is designed to comply with API 675 due to its technical features, including full-motion drive, automatic bleeding etc.

Product description

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

The hydraulic diaphragm metering pump Hydro/ 3 API 675 (HA3e) meets the requirements of API 675, among other things due to its full-motion drive and automatic bleeding. Some of the many drive options are also approved for use in areas at risk from explosion.

Your benefits

Excellent process reliability:

  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system
  • Integrated hydraulic relief valve with ventilation function
  • Metering reproducibility is better than ± 1% in the 10-100% 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 (boxer principle) 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: 4,200 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 % within the 10 – 100% stroke volume range under defined conditions and with correct installation (API 675)
    • PTFE multi-layer diaphragm with electrical diaphragm rupture warning system via a contact
    • Integrated hydraulic relief and bleed valve
    • Full-motion drive
    • Wetted materials: PVDF, PTFE+25% carbon, stainless steel 1.4571, Hastelloy C.
    • A wide range of power end versions is available: Three-phase AC 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

    When pumps are selected in accordance with API 675 (control range 1:10), the permitted rated flow configuration in the stated range is possible.

    Example: a piston 26 mm, pressure 25 bar and stroke rate 150 strokes/min results in (40) - 59, i.e. the control range of 1:10 is met for a rated flow of between 40 l/h and 59 l/h.
