CM(E) range of electronically operated pumps available in stainless steel, (‘EN 1.4301/AISI304’ or ‘EN 1.4401 /AISI316’) and cast iron. The pumps are supplied with Sic-Sic mechanical shaft seals and FKM or EPDM seals. Maximum operating parameters: Cast iron models: Maximum working pressure 6.0 bar @ 90°C. Maximum working pressure 10.0 bar @ 40°C. Stainless steel models (not self-priming variants): Maximum working pressure 10.0 bar @ 99°C. Maximum working pressure 16.0 bar @ 90°C. Stainless steel self-priming models (CM(E) 1, 3 & 5 (AISI 304) only): Maximum working pressure 10.0 or 16.0 bar @ 60°C.
