Hydraulic diaphragm metering pump Hydro/ 4 API 675

Capacity range of single head pump: 252 – 1,506 l/h; 40 – 7 bar

The Hydro/ 4 API 675 is an extremely robust hydraulic diaphragm metering pump, which meets the most exacting safety requirements and is designed in accordance with API 675. This is ensured by the PTFE multi-layer diaphragm with diaphragm monitoring, the full-motion drive and automatic bleeding, for example. Its modular construction makes it extremely versatile.

Product description

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

The Hydro/ 4 API 675 hydraulic diaphragm metering pump (HA4a), together with the Hydro/ 2 and Hydro/ 3 pumps, represents an integrated product range with stroke lengths of 15 and/or 20 mm. The Hydro API 675 family, equipped with full-motion drive and automatic bleeding, therefore covers the capacity range of 4 to 1,506 l/h at 100 – 7 bar. They also meet the requirements of API 675.

Your benefits

Excellent process reliability:

  • PTFE multi-layer diaphragm with integrated diaphragm monitoring with condition signals sent via contact
  • 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 correct 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

    • Metering reproducibility is better than ± 1% in the 10 – 100% stroke volume range under defined conditions and with correct installation
    • PTFE multi-layer diaphragm with electrical diaphragm monitoring with condition signals sent via 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 or standard three-phase motors or motors for use in areas at risk from explosion, different flange designs for use of customer-specific motors
    • Degree of protection: IP 55

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

    Example: a plunger 52 mm, pressure 10 bar and stroke rate 136 strokes/min results in (200) - 276, i.e. the adjustment range of 1:10 is met for a rate flow of between 200 l/h and 276 l/h.

    Version PVDF max. 25 bar

    Pump types with "–" do not meet the test requirements of API 675 with regard to the 1:10 adjustment range

    Motor data sheets can be requested for more information. Special motors or special motor flanges are available on request.

    The motors are designed in compliance with the Ecodesign 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/EU in premises at risk from explosion. Ensure that the explosion group, category and degree of protection specified on the label corresponds to or is better than the conditions prevalent in the intended field of application.
