A closer look at the series
The 3M catalogue presents an industrial-style centrifugal pump with AISI 304 stainless-steel wetted components. Its back pull-out construction permits access to the rotating assembly without removing connected pipework, as described by the source. The brochure lists square or round motor configurations and provides a model code based on discharge size, nominal impeller diameter and power.
It also notes that some impure liquids may be suitable, but this must be assessed against the exact solids characteristics and the selected pump. Use the catalogue curves and operating limits to choose the hydraulic size. Check motor supply, materials and seal details for the chosen configuration before specifying it.
Features
- AISI 304 wetted components
- Back pull-out construction
- Square or round motor configurations
- AISI 316 option stated on request
Applications
- Clean-water distribution
- Civil pumping systems
- Industrial water transfer
Materials
AISI 304 wetted parts, including pump casing, impeller and shaft; SiC/carbon/SS304 mechanical seal. AISI 316 construction is available on request, not a universal standard for the series.
Operating conditions
Liquid temperature −10 to +120 °C; ambient temperature 0 to +50 °C; maximum working pressure 16 bar; continuous duty S1. The overview lists three-phase 380–415 V supply.
Construction and application
Before selecting
- Select the 3M size and curve from the required flow and head.
- Check liquid and ambient temperatures and the 16 bar pressure limit.
- Confirm standard AISI 304 or requested AISI 316 and the electrical supply.
Your questions
Series questions
Is AISI 316 the standard construction?
No. The description specifies stainless steel 304 and lists AISI 316 on request. Confirm the ordered construction.
Can the pump be serviced without removing the pipes?
The brochure describes a back pull-out design and says pipe removal is not required for that access.
