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
