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

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

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

    PVDF version max. 25 bar, PTFE + 25 % carbon; PTFE up to 10 bar

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