GNWQ Cutter Sewage Pump – 220V vs 380V, How to Choose Voltage

GNWQ cutter pumps come in single-phase 220 V and three-phase 380 V, and picking the right one matters. The rule of thumb is simple: small pumps for homes and small premises run on 220 V, while anything larger — and all industrial and municipal duty — uses 380 V.

Which one for you?

The smallest models (around 0.75–1.5 kW) are offered in 220 V so they work on an ordinary domestic supply — ideal for a house, shop or small guesthouse. From roughly 2.2 kW upward, GNWQ pumps are three-phase 380 V, which suits the higher power and steady running that industrial and municipal sites demand.

If you’re not sure what supply your site has, tell us and we’ll match the pump to it.
