CM / EN733 horizontal pump range
CM is a close-coupled centrifugal range presented to the EN733 pump standard. The catalogue describes a coated cast-iron casing, alternative impeller materials and continuous-duty motor construction. It addresses clean-water supply and circulation across a broad set of civil, agricultural and industrial uses.
Range bounds are a catalogue overview. Check flow and head together on the selected model curve; maximum values are not a guaranteed combined duty point.
Series catalogue ↗Series overview
The CM series uses a close-coupled arrangement and is documented with performance curves, materials, operating limits and model codes. Its catalogue lists a grey cast-iron casing with protective coating and impeller material options that vary by build. The described applications include water supply, cleaning systems, pressure boosting, firefighting sets, irrigation and air-conditioning circulation.
The pumped liquid should be clean and non-aggressive to the selected pump materials. Because the family spans many sizes, the installation and motor selection should follow the specific model curve and connection details. The range is presented to the EN733 pump standard; installation details depend on the selected model.
Grey-cast-iron casing; cast-iron, AISI 304 or brass impeller; 45# steel or AISI 316 shaft, according to configuration. Mechanical shaft seal and grease-lubricated rolling bearings.
Clean water and liquids that are not chemically aggressive to the pump materials. Liquid temperature −10 to 120 °C, ambient temperature −10 to 50 °C, maximum working pressure 16 bar and continuous duty S1.
The catalogue lists cast iron, AISI 304 and brass options. Confirm the material of the selected configuration.
The catalogue limits use to clean water and liquids that are not chemically aggressive toward the pump materials. Check the actual liquid before specifying a pump.

2CDX places twin centrifugal impellers in a horizontal stainless steel pump. Its catalogue lists water supply, water treatment, irrigation and air-conditioning duties. The two-impeller arrangement offers a different flow-head selection from the single-impeller CDX range, so the published curve should guide specification.

3M is a stainless steel standard-pump series for clean-water and selected industrial transfer duties. The catalogue identifies stainless steel wetted parts and a back pull-out arrangement that gives access to the rotating assembly without removing pipework. Its application and material profile differ from the cast-iron CM range.

CDX is a compact horizontal centrifugal pump with a single impeller, axial suction and radial discharge. The catalogue identifies AISI 304 stainless steel hydraulic components and threaded connections. It covers pressure boosting and general water transfer where the selected liquid matches the pump materials.
