SA / Multistage submersible well-water range
SA groups several well-pump sizes within one borehole catalogue. The range uses multistage hydraulics for water supply, with plastic impellers identified in its construction pages. Select the listed size and model by well conditions, required flow and head, electrical supply and the catalogue’s operating limits.
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 SA catalogue covers submersible water supply across several well sizes and includes model codes, motor options, performance tables and curves. Applications include water supply from wells or reservoirs, domestic, civil and industrial systems, and garden irrigation. The construction tables identify plastic impellers and AISI 304 stainless steel external casings, with other materials specified by pump size and component.
The overview states a maximum fluid temperature of 35 °C and maximum sand content of 0.25%. Check the actual water quality against these limits rather than inferring suitability from impeller material alone. Confirm the well opening, dynamic water level, required flow and total head, then select the exact model and electrical arrangement from its table.
AISI 304 stainless steel external pump and motor casings, plastic PC diffusers and plastic POM impellers in the listed constructions. Delivery casing materials vary with the selected size and configuration.
Maximum fluid temperature 35 °C and maximum sand content 0.25%. Select the well-size range and electrical configuration from the applicable model page.
The construction tables specify POM plastic impellers and PC plastic diffusers, with stainless steel external casings. Check the material table for the selected size.
Use the model performance curve and required flow and total head. The model code includes the number of impellers, so models in one flow family can have different heads.

Choose the pump by the liquid, required flow and total head, electrical supply and installation conditions.
SP is the stainless steel borehole family, with curves and performance tables across several listed well-pump sizes. Stainless steel impellers distinguish it from SA's plastic-impeller construction. The catalogue gives the data needed to match water supply duty to well size, stage count and motor arrangement.
