3M / Horizontal centrifugal process pump
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.
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 3M catalogue describes an AISI 304 stainless steel standard pump with stainless steel wetted components and a back pull-out design. Square and round motor configurations are shown, and AISI 316 is listed as an option on request. Applications cover domestic, civil and industrial clean-water service, with some impure liquids mentioned subject to the documented operating limits.
The back pull-out arrangement can simplify access to internal parts during maintenance while the connected pipework stays in place. For specification, check the actual curve, motor and liquid compatibility rather than applying one material statement to every optional build. This family is catalogued separately from the close-coupled CM series.
AISI 304 wetted hydraulic parts, including casing, impeller and shaft, with a SiC/carbon/SS304 mechanical seal. AISI 316 construction is available on request.
Liquid temperature −10 to 120 °C, ambient temperature 0–50 °C, maximum working pressure 16 bar and continuous duty S1. Check compatibility for liquids other than clean water.
The catalogue describes AISI 304 wetted parts and offers AISI 316 on request. Confirm the material configuration before ordering.
The catalogue states that the design allows access without removing the pipes. Plan service access for the selected installation.

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.

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.

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.
