Product Overview

The Davey DynaDrive DD90-11NPT is a higher-capacity variable-speed constant-pressure pump for compatible clean-water systems with substantial or changing simultaneous demand. Its integrated drive and controller vary motor speed as water use increases or decreases, helping maintain the selected delivery pressure for large household systems, acreage water supply, irrigation, and selected small commercial boosting applications.

This model should be selected from the manufacturer's performance information using the required flow at the intended pressure. Confirm simultaneous demand, elevation, suction conditions, pipe friction, inlet and outlet sizing, source-water capacity, and electrical requirements before ordering. Maximum pressure and flow figures should not be treated as one combined operating point. The pump also requires correct priming, unrestricted supply piping, appropriate pressure settings, and proper commissioning. Follow the Davey DynaDrive installation documentation for the complete electrical, hydraulic, control, and service requirements.
