Series E/F - Stainless steel gear flange pumps

The gear flange pumps of the Series E/F are designed as stainless steel flange pumps with housing and gears made of material 1.4571 (V4A).
The pumps are suitable for corrosive and chemically demanding media for which a gray cast iron design is not sufficiently resistant.
