DOUBLE-CHANNEL · AISI 304
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.
Range technical data
- Power range
- 2.2–7.5 kW
- Maximum flow
- 120 m³/h
- Maximum head
- 24 m
- Solids passage
- 6–52 mm
- Electrical supply
- 3~ 380–415 V
These figures describe the catalogue range or stated subrange. Maximum flow and maximum head/pressure are not a single duty point. Select the exact model from its curve and confirm materials, electrical version and connections.

A closer look at the series
The FS stainless-sewage range uses a double-channel impeller for suspended solids within the passage limits specified by the relevant model. The pump casing, motor casing, impeller and shaft are listed as AISI 304 stainless steel, with mechanical-seal materials detailed in the catalogue. Suggested settings include water supply and circulation for farming and fisheries, garden or landscape equipment, and drainage or filtration.
Flow capacity and head differ among the listed pumps, so the series name alone does not define a duty point. Confirm the liquid condition, immersion depth, electrical variant and Q–H curve for the chosen configuration before assigning it to an installation.
Features
- Double-channel impeller
- AISI 304 casing, impeller and shaft
- Model-specific suspended-solids passage
- Mechanical-seal materials listed in brochure
Applications
- Farm and fishery water circulation
- Garden and landscape water features
- Drainage and filtration
Materials
Pump casing, motor casing, impeller and shaft are specified as AISI 304 stainless steel. The seal combination is SiC/SiC + carbon/SiC, with an NBR O-ring.
Operating conditions
Liquid temperature 0 to +50 °C; immersion depth no more than 5 m. The double-channel impeller brochure lists a 6–52 mm solids passage. Check the selected model rather than treating the range as a universal passage.
Construction and application
Before selecting
- Use the curves in the stainless-steel FS brochure for the required flow and head.
- Check actual solids, liquid temperature and immersion depth.
- Confirm the three-phase supply and compatibility of AISI 304, seals and NBR with the liquid.

Series questions
Is this the same selection table as the light-sewage FS brochure?
No. This stainless-steel FS brochure lists its own models, double-channel impeller and operating limits. Use this PDF for this range.
Can it be installed deeper than 5 m?
The catalogue limit is an immersion depth of 5 m. A deeper installation is outside the stated conditions.

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.

KTZ-LH submersible drainage pumps
KTZ and LH are submersible drainage pump families for civil engineering, mines and quarries, sewage-treatment plants and general pumping. Their construction and immersion limits must be checked separately for the selected family and model.
