Alfa Laval FM Centrifugal Pump

The Low Capacity Pump

FM-OS Centrifugal Pump

Application
Centrifugal pump FM-OS is designed for use in food, pharmaceutical, chemical and other industries where acid-resistant steel is resistant to the products to be pumped.

Standard design
All product wetted parts, ie. pump casing, impeller and pump shaft, are made of acid-resistant steel 1.4404 (316L). Screws, yoke and nuts are made of stainless steel 1.4301 (304). Seals are made of Nitrile (NBR).

Shaft seal
Mechanical single or flushed seal with stationary seal ring of acid-resistant steel AISI 329 with sealing surface of silicon carbid and with rotating seal ring of carbon.
