Questions buyers ask

Single-phase or three-phase for deep-well pumps?

Both are in the range: STM motors are single-phase 220–240 V or three-phase 380–415 V, 50 Hz. The model code tells you which — M in the code means single-phase.

Do the light submersibles switch themselves on and off?

The QDX models marked (F) include a float switch — the pump starts and stops with the water level, which is what you want for cellars, tanks and rain collection.

Can I get a complete pressure set?

Yes — pair the pump with a pressure tank, pressure switch or automatic pressure controller from the accessories range, and we ship the set together.
