GrowoniX DDP4-VARI Variable Speed Delivery Pump
A storage tank of RO water is only useful if you can get it where it needs to go with steady pressure. The DDP4-VARI is a variable speed delivery pump that reads demand and adjusts on the fly—speeding up as more valves open and easing back as they close—to maintain 55 PSI at up to 4 GPM. It runs on 115V (60Hz, 1.6A) with a high-pressure cutoff at 60 PSI, so the pump isn't fighting itself once the lines are charged.
On-Demand Water Delivery That Holds Pressure
Plumb it on the outlet side of a reservoir or RO storage tank and let it pressurize feed lines, float-valve top-offs, or a few drip zones at once. The 1/2" OD tube ports make it an easy inline fit, and the intermittent duty cycle suits start-stop delivery rather than nonstop recirculation. Thermal shutdown protects the motor if it overheats, and an automatic shutoff trips after about two minutes of wide-open flow—handy insurance against a left-open valve or a line that pops loose.
Key Features
- Variable Speed Motor: Digitally adjusts flow to hold 55 PSI as valves open and close.
- 4 GPM Max Flow: Feeds multiple valves or zones at once from a storage tank.
- High-Pressure Cutoff (60 PSI): Stops the pump from over-pressurizing charged lines.
- Thermal Shutdown + Auto Shutoff: Motor protection plus a ~2-minute wide-open-flow safety stop.
- 1/2" OD Tube Ports: Drops inline on standard 1/2" delivery plumbing.
- 115V / 1.6A: Standard household power with low current draw for intermittent delivery duty.
