The Davey DynaDrive DD90-11NPT is built-tough constant pressure for demanding water systems. Integrated Variable Speed Drive technology adjusts motor speed to maintain steady pressure whether you're running the shower, dishwasher, and washing machine at once or watering the garden. All-stainless hydraulic components are built to resist corrosion and deliver years of reliable service. An integrated LCD panel makes it easy to monitor live system data and dial in your preferred pressure setting. An air purging valve simplifies priming and makes the system less susceptible to air leaks in your suction line.
For residential pressure boosting, agricultural systems, irrigation, and general water transfer. Indoor installation only. Two units can be linked for parallel operation with automatic lead-lag rotation (communication cable required).
Key Specs: 0.9 kW output, 220-240V, 1-1/4" NPT inlet / 1" NPT outlet, NSF/ANSI 61 certified
