Application
MR is a liquid-ring pump specially designed for pumping
liquids containing air or gas.
The pump is for use in food, chemical, pharmaceutical and similar
industries.
The pump is mainly used for CIP-return application.
Standard design
All product wetted parts, i.e. pump casing, casing cover
and impeller are made of acid-resistant steel AISI 316L. Seals are made of
EPDM rubber.
Cap nuts, legs, leg brackets and shroud are made of stainless steel AISI
304. The shroud has noise absorbing lining inside.
MR-166S, 185S and 200S: Adaptor is in cast iron which is zinc coated and
laquered making it highly corrosion resistant.
Shaft seal
On MR-166S, -185S and 200S, the mechanical single seals
have stationary seal rings of acid-resistant steel AISI 329 and rotating
seal rings of carbon.
The MR-300 has mechanical single seal with stationary seal rings of carbon
and rotating seal rings of acid-resistant steel AISI 329.
