The DynaDrive features an integrated controller that is easy to set up and use. It allows you to set your desired water pressure while also being energy efficient. By reducing the pressure on your system when it's not needed, Davey DynaDrive reduces the energy consumed, saving you money. Davey DynaDrive has been certified and tested to comply with the requirements of the UL778 standard. The UL778 standard covers submersible and non-submersible motor-operated pumps intended to be used in ordinary locations in accordance with the National Electrical Code, NFPA 70.Davey DynaDrive is a horizontal multistage centrifugal pump with all hydraulic parts in stainless-steel - suitable for high water temperatures, corrosion and wear resistant, compact design and easy to install.Product Features Stainless-steel impellers with high efficiency impeller profile and thick self-centering impeller neck rings for: High efficiency, Reduced power consumption, Low noise output Air purging valve and stage porting: Easier priming, Less susceptible to air leaks, Improved dependability Impellers mounted directly on extended motor shaft: Maximize performance per stage, High efficiency, Long motor and pump life, Increased wear resistance Pump casing assembly attached to motor bracket at 8 points with o-ring seal: Complete stainless casing, Better sealing, Longer service life Davey built, totally enclosed fan cooled (TFEC) electric motor: Sealed and greased for life motor bearings, Oversized drive bearing, Longer life, Easy service, Economical and quiet running Product Specifications Inlet: 1-1/4" FNPT Outlet: 1" FNPT Voltage: 220-240V Max Set Pressure: 87 psi Max. flow rate @ 300kPa (43psi): 16 gpm Max. flow rate @ 400kPa (58psi): 13 gpm Max. casing pressure 145 psi Min. cut-in pressure (gauge): 1-1/2 psi Default cut-in pressure: 7psi less than set pressure Max. cut-in pressure: 3psi less than set pressure Operating water temp range: 32° - 176ºF
