Hydraulic Diaphragm Metering Pump HYDRO API

Capacity range of single-head pump: 7 – 1,506 l/h, 100 – 7 bar

The HYDRO 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 API 675 hydraulic diaphragm metering pumps form an integrated product range with stroke lengths of 15 or 20 mm. Equipped with full-motion drive and automatic bleeding, they therefore cover the capacity range of 7 to 1506 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
  • 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

    Piston Ø 9 and 12, version with double ball valves.

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

    The litre capacity indicated using [...] is the maximum litre capacity with an applicable control range of 1:5 and does not therefore satisfy API 675.

    Example: a 12 mm piston, 40 bar pressure and stroke rate of 125 strokes/min results in (4.5) - 8.7, i.e. the control range of 1:10 is met for a rated flow of between 4.5 l/h and 8.7 l/h.

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

    The litre capacity indicated using [...] is the maximum litre capacity with an applicable control range of 1:5 and does not therefore satisfy API 675.

    Example: with 16 mm piston, pressure 25 bar and stroke rate of 150 strokes/min gives (14) - 17.5, i.e. the control range of 1:10 is met for a rated flow of between 14 l/h and 17.5 l/h.

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

    The litre capacity indicated using [...] is the maximum litre capacity with an applicable control range of 1:5 and does not therefore satisfy API 675.

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

    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.

    Overview

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

    The HYDRO API 675 hydraulic diaphragm metering pumps form an integrated product range with stroke lengths of 15 or 20 mm. Equipped with full-motion drive and automatic bleeding, they therefore cover the capacity range of 7 to 1506 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
    • 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
