In the “worlds” of electroplating and industrial washing, double diaphragm pumps and damper are indispensable components for the transfer and handling of liquid fluids present in the “galvanic baths” and washing tanks. These components have excellent mechanical qualities and chemical resistance and are suitable for all types of liquids, even when the working conditions are “severe”. The materials used for the construction of the double diaphragm pumps and the FLUIMAC series damper allow the use in both alkaline and acid solutions, even at high temperatures. Double diaphragm pumps and dampers treated by the company S & RIND S.r.l. are those manufactured by the Italian company FLUIMAC S.r.l ..
