A closer look at the series
The CM brochure describes radial-impeller pumps designed for medium to high flow and substantial discharge head. Its range overview separates several nominal pump sizes, each with further impeller and motor combinations, and provides individual Q–H tables on later pages. The pump body and base support are listed as G20 cast iron, while the impeller may be cast iron, AISI 304 or brass according to configuration; the shaft is specified as AISI 316 stainless steel.
CM is intended for chemically clean liquids free from foreign matter. Choose the actual size and impeller trim by the target duty and confirm materials, motor and temperature conditions.
