The CM is a reliable, quiet and compact horizontal end-suction pump. The pump adopts a modular design, which allows for easy customization. The CM is available in cast iron and stainless steel versions.
Innovative Modular Design: CM Horizontal Multi-stage Pump
The CM horizontal multi-stage pump is a close-coupled pump that provides reliable flow control solutions for systems of different sizes. Utilizing centrifugal modular technology, its interchangeable modules make it an essential part in water treatment, cleaning and disinfection, temperature control, chemical processing, pharmaceuticals, and other fields.
The CM series of horizontal multi-stage pumps combines the features of being lightweight, low-noise, highly reliable, and easy to maintain. To a certain extent, it reduces the hidden costs of the system, such as energy consumption, operating temperature, vibration, and noise. The modular design of the CM horizontal multi-stage pump, together with the application of reliable heat treatment technology, ensures its long service life and high-efficiency performance.

CM 25-4 A-R-A-E-AQQE F-A-A-N
A compact and highly reliable horizontal multi-stage end-suction centrifugal pump with an axial suction port and a radial exhaust port. The shaft, impeller, and chamber are made of stainless steel, while the liquid inlet and outlet parts are made of cast iron. The mechanical shaft seal is a specially designed unbalanced O-ring seal. The pipe connection is achieved through internal Whitworth pipe threads (Rp (ISO 7/1)). A 3-phase asynchronous motor with a cooling fan and a mounting bracket is installed on the water pump.
