Chemical Standard Pumps

(ISO 2858 / DIN 24256)

Application

Chemical industry, food industry, water treatment and manufacture of apparatus.

Applicable for any kind of liquids which do not tend to crystallize and do not contain a very low percentage of solids. The material combinations are selected under these aspects.
