The Grundfos SPE range gathers submersible pumps fitted with an internal permanent-magnet (IPM) motor and variable speed. The SPE 125 covers a flow rate up to 160 m³/h and a head up to 120 m, with a pump efficiency of 79%.

The MS6000P permanent-magnet motor delivers 8 to 10% extra efficiency compared to an equivalent asynchronous motor, for reduced energy consumption and a longer service life. Construction is fully stainless steel (EN 1.4301 standard, EN 1.4401 or EN 1.4539 as an option for corrosive environments).

The IPM motor is synchronous: it requires a variable-frequency drive. The SPE 125 operates with the Grundfos CUE drive on a three-phase mains supply, or with a solar inverter for autonomous photovoltaic pumping.

Applications: drinking-water supply, agricultural and horticultural irrigation, groundwater lowering, boosting and constant-pressure systems. Rp 6 connection, 10" diameter.

SINES Export is the wholesaler, distributor and exporter specialised in SPE submersible pumps for worldwide markets. Our teams support installers, resellers and distributors for export to Africa, the Maghreb and the Middle East.

SPE + RSI solar pumping: paired with the Grundfos RSI solar inverter, the SPE 125 adapts its speed in real time to the available sunlight, with no battery and no grid. Our solar pump inverters GRUNDFOS RSI and ABB ACS355 pair easily with the SPE range, creating a solar powered system with maximum flexibility.
