A closer look at the series
SF is described for water supply from wells or reservoirs and high-head transfer. Its construction includes a cast-aluminium impeller, plus an AISI 304 stainless-steel strainer, external motor casing and top cover, together with a rewindable motor. Single-phase and three-phase configurations appear in the range, and certain single-phase models can have a float switch identified by the model suffix.
The catalogue also records limits for liquid temperature and sand content. Choose an SF pump from its own Q–H curve and operating conditions for the intended supply or irrigation duty.
Features
- High-head submersible hydraulic range
- AISI 304 external casing, cover and strainer
- Single- and three-phase variants
- Float-switch option on identified single-phase models
Applications
- Water supply from wells or reservoirs
- Garden water systems
- Irrigation
Materials
Cast-aluminium impeller; AISI 304 stainless-steel strainer, external motor casing and top cover; graphite/ceramic mechanical seal. This is not an all-stainless impeller construction.
Operating conditions
Maximum liquid temperature +40 °C; maximum sand content 0.1%. Single-phase models with suffix F can have a float switch. The brochure distinguishes single-phase models with m from three-phase models without m.
Construction and application
Before selecting
- Match the required supply or irrigation duty to the exact SF curve.
- Check sand content and the liquid temperature limit.
- Choose electrical phase and confirm the m and F model suffixes.
Your questions
Series questions
Is the SF impeller made of stainless steel?
The SF materials table specifies cast aluminium for the impeller. The strainer, external motor casing and top cover are AISI 304 stainless steel.
Does every SF model include a float switch?
No. The catalogue associates a float switch with single-phase models carrying suffix F. Confirm the complete model code.

WC
WC cutter submersible sewage pumps
The WC series combines a submersible sewage pump with a cutter for water containing fibrous material. The catalogue spans several discharge sizes and hydraulic curves, allowing the duty point to be checked for wastewater treatment, industrial drainage and agricultural irrigation.
FS
FS stainless-steel submersible pumps for light sewage
This FS catalogue covers AISI 304 submersible electric pumps for clean or slightly dirty water in domestic, workshop and industrial systems. It specifies solids passage by model and gives separate electrical variants, so the correct configuration depends on both liquid and duty point.
FS-INOX
FS stainless-steel submersible sewage pumps
The FS stainless-sewage range combines a double-channel impeller with AISI 304 wetted components. Its model range addresses clean water and sewage, with passage of suspended solids stated in the catalogue for each configuration rather than assumed across all FS pumps.
