Davey DynaDrive DD15-35NPT Constant Pressure Pump Brand: Davey | SKU: DD15-35NPT Product Overview The Davey DynaDrive DD15-35NPT is a compact variable-speed pump system designed to maintain a selected water pressure as demand changes. Its integrated drive and pressure controller increase or reduce motor speed as fixtures open and close, helping avoid the noticeable pressure swings associated with a fixed-speed pump in a changing-demand system. It can be used for compatible household pressure boosting, tank-fed water supply, turf watering, and irrigation supplied with clean water. A constant-pressure controller does not eliminate the need to size the pump hydraulically. Confirm the combined flow expected from simultaneous fixtures or irrigation outlets at the chosen pressure, then include elevation, pipe friction, suction lift, inlet conditions, and water-source capacity. The system must also match the listed 110-120V single-phase supply and 1 in. FNPT connections. Before installation, verify the pressure setting, pipe layout, priming method, available source water, and required duty point. Follow the DynaDrive instructions for electrical connection, water-source requirements, commissioning, and adjustment. Key Features: Integrated variable-speed drive and pressure controller Stainless steel impellers and hydraulic components Approximately 12 GPM at 43 PSI Maximum set pressure of approximately 87 PSI Air-purging valve and stage porting Compact constant-pressure system Common Uses: Household water-pressure boosting Tank-fed home water systems Irrigation and turf watering Applications with changing simultaneous water demand Technical Specifications: SKU: DD15-35NPT Pump Type: Variable-speed constant-pressure pump Flow at 43 PSI: Approximately 12 GPM Maximum Set Pressure: Approximately 87 PSI Voltage: 110-120V single phase Inlet: 1 in. FNPT Outlet: 1 in. FNPT Hydraulic Materials: Stainless steel Compatibility and Installation Notes: Select the pump using the required flow at the target pressure, not maximum values alone. Follow the Davey DynaDrive installation instructions for water source requirements, pressure settings, pipework, priming, electrical supply, and system commissioning.
