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 (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.
