The Eco-Steady™️ Submersible Pump Drive is a Variable Frequency Drive (VFD) designed for three-phase, 220V submersible well pumps up to 1.5 HP. Rather than running your pump at full speed every cycle, the Eco-Steady™️ Pump Drive continuously monitors system pressure and varies motor speed to match exactly what you need — delivering stable, consistent water pressure at every outlet regardless of flow rate.

No more pressure drops when someone opens a faucet while you're in the shower. No more spitting sprinkler heads when the dishwasher kicks on. No more sluggish flow at the end of a drip irrigation line. The Eco-Steady™️ Submersible Pump Drive eliminates the spikes and drops that come with traditional on/off pump cycling.

Setup could not be easier. No programming, no complicated wire splices, no contractor fees. Set your target pressure right out of the box, finish your plumbing connections, and the Eco-Steady™️ Submersible Pump Drive handles the rest. Our USA-based engineers are on the other end of the phone before and after the sale, because our job isn't done until your water is running. Total control over your water supply, without the middleman.

The Eco-Steady™️ Submersible Pump Drive delivers real, measurable savings on operating costs. By matching motor speed to actual demand rather than running at full power every cycle, customers typically see 30–50% reductions in pump running costs at average U.S. electricity rates.
High-capacity pump ends regularly drawing below their rated flow realize the greatest savings, since the drive eliminates the energy cost of repeated full-speed startups.
Less cycling also means significantly less wear on your motor, pressure tank, and plumbing components, reducing long-term replacement costs and extending the life of your whole system.
The Eco-Steady™️ Submersible Pump Drive enclosure is IP55-rated, providing protection against water and dust intrusion that is roughly equivalent to NEMA13-rated protection.
Every Eco-Steady™️ Submersible Pump Drive comes with the RPS Tri-Safe Protection Package:
- Dry Run Protection
- Over-voltage and Under-voltage Protection
- Electrical Protection Against Motor Overload
