Single Phase VFD for Water Pump – 220V to 3-Phase 380V/400V from One Outlet
A single phase VFD for water pump lets you run a standard three-phase pump motor directly from a 220V single-phase outlet. SHZK 300-S3 series is a practical single phase to three phase converter built for pumps: it takes 220V to 380V single-phase input and outputs true three-phase 380V/400V/415V, matching the three-phase motors common across Southeast Asia – no grid upgrade, no phase conversion add-on, no rewinding.
Run 3-Phase Pump Motors on Single Phase Supply
If you need to run a 3 phase motor on single phase for any pump duty, the S3 single-phase inverter covers 0.75kW to 18.5kW, including single phase VFD for irrigation pump, single phase VFD for deep well pump, borehole pump inverter single to three phase, and booster pump variable frequency drive setups.
- 220v to 380v converter for water pump – straight replacement for VFD + transformer combos
- True 3-phase output drives submersible, centrifugal and multistage pumps
- Built-in PID keeps constant pressure, ends water hammer via soft start
- Solar-ready models pair with PV for off-grid irrigation
Every S3 single-phase VFD is 100% full-load aged-tested on a rig like this before shipping – so your 3-phase pump motor is driven by a unit we know works.
Which Applications?
Agricultural irrigation, livestock watering, borehole and deep well pump supply, boosting home water pressure, fishpond aeration and small farms – any where a 380V/400V three-phase pump motor must run from a single 220V feed. Models from 0.75kW to 18.5kW suit pumps from 1HP to 25HP.
Stainless submersible / drain pump – one of the toughest pump classes an S3 single-phase VFD drives. Our aging-test and field record covers submersible, borehole and multistage duties.
