The pump selection in accordance with API 675 (adjustment range 1:10) is possible for the rated flow given in the above table.
Example: with plunger 52 mm, pressure 10 bar and stroke rate 136 H/min gives (200) - 276, i.e. the adjustment range of 1:10 is met for a rated flow between 200 l/h and 276 l/h.
Version PVDF max. 25 bar
Pump types marked with "–" do not meet the requirements of the API 675 concerning the adjustment range 1:10

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.
