Grundfos CM-A 240v Series Horizontal Multistage Cast Iron/304ss End Suction Pumps
Grundfos CM-A Horizontal Multistage Cast Iron Pump with 304ss Wetted Components - Single Phase
The Grundfos CM-A Series are compact, horizontal multistage centrifugal pumps engineered for reliability, quiet performance, and seamless integration. Designed with a modular construction (Centrifugal Modular), these pumps are ideal for a range of light industrial and commercial applications including water treatment, temperature control, cleaning systems, and general pressure boosting.
Each pump features a close-coupled motor, axial suction and radial discharge, and wetted components made from robust cast iron and corrosion-resistant 304 stainless steel. The mechanical shaft seal is an unbalanced, O-ring design for dependable leak prevention. These single-phase models come pre-fitted with IP55-rated fan-cooled asynchronous motors and are available with or without a lead and plug, depending on the version.
With inlet and outlet ports designed for Rp internal threads and a broad operating temperature range from -30°C to +120°C, the CM-A Series offers a flexible, plug-and-play solution for compact installations requiring performance, durability, and low maintenance.
