The Grundfos SP 1A is designed for reliable groundwater abstraction from narrow boreholes and wells. The hydraulic parts are made from corrosion-resistant AISI 304 stainless steel.

This page lists only the standard three-phase AISI 304 complete pump sets from the Grundfos 2026 catalogue. Single-phase and N/R material variants are not included.

The published HMT values are read at Q=0 from the official 50 Hz performance curve and rounded to the nearest metre.

Typical applications include drinking and process water supply, agricultural irrigation, pressure boosting and groundwater lowering.
