OPEN IMPELLER · FIBROUS WATER
SS and SSM submersible sewage pumps

SS and SSM are submersible sewage pumps with an open impeller for water containing fibers. The catalogue distinguishes three-phase SS versions without a float switch from single-phase SSM variants fitted with a float switch, with hydraulic selection made from the model table.
Range technical data
- Power range
- 0.15–3 kW
- Maximum flow
- 60 m³/h
- Maximum head
- 22 m
- Electrical supply
- SS: 3~ 380–415 V, without float; SSM…F: 1~ 220–240 V, with float; 50 Hz
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 SS brochure groups two related electrical configurations under one wastewater family. The SS codes identify three-phase pumps without a float switch, while the SSM codes with an F suffix identify single-phase pumps fitted with one. An open impeller is stated for the series, together with suitability for water containing fibers.
The document lists a cast-iron outer motor casing, graphite-ceramic mechanical seal and rewindable motor. Application examples include sewage treatment, industrial drainage and agricultural irrigation. Flow and head vary by model; select from the tabulated Q–H data and verify the electrical and float-switch configuration rather than assuming all SS and SSM units are interchangeable.
Features
- Open-impeller hydraulic design
- SS three-phase versions without float switch
- SSM single-phase versions with float switch
- Cast-iron outer motor casing
Applications
- Sewage-treatment plants
- Industrial drainage
- Agricultural irrigation
Materials
G20 cast-iron outer motor casing, graphite–ceramic mechanical seal and shaft listed as AISI 304 SS–ASTM 5140. The brochure identifies an open impeller.
Operating conditions
Maximum liquid temperature +50 °C; suitable for water containing fibres. SS models are three-phase without a float switch; SSM…F models are single-phase with a float switch, as labelled in the catalogue.
Construction and application
Before selecting
- Select the flow–head point from the exact SS or SSM model row.
- Check liquid temperature and whether the liquid contains fibres.
- Confirm SS three-phase without float or SSM…F single-phase with float.
Your questions
Series questions
What is the difference between SS and SSM…F?
The brochure labels SS as three-phase without a float switch and SSM…F as single-phase with a float switch.
Are maximum flow and maximum head one operating point?
No. The table explicitly defines Q max at H = 0. Read the required head at the actual flow on the selected model curve.
Original catalogue
SS / PDF
Use the single-page SS/SSM table and its labelled electrical/float versions. Q max is expressly defined at H = 0, so read the required duty on the actual model curve.
