Yes, but it won’t last long.

When the intake screen lifts the water line, the motor continues to rotate and no water is surrounding the intake screen. Water usually cools the motor and lubricates the shaft seal. Without that liquid, heat builds quickly. Metal parts expand, plastic parts soften, and the seal can burn in minutes. A 300 W garden pump and a 20 kW deep-well unit face the same danger. Even stainless-steel impellers cannot survive long without water.

The problem has nothing to do with the power source. Direct current does not prevent damage. Fast shut-off is the real safeguard. SAMKING controllers track flow and motor current. A sudden drop in flow or a sharp rise in current tells the logic that the well is dry. The controller stops the pump and waits for water to return. Hybrid AC/DC versions share this feature, so protection works whether the system runs on solar panels, batteries, or the grid.

Extras such as GPRS links, cloud dashboards, and PayGo locks let an owner or technician clear a dry-run alarm from a phone. That cuts downtime and repair costs.

Always order dry-run protection and keep probes clean. Regularly.
