Impro White Motor 505750A5120AFAAA Impro

White Roller Stator Motor – 505750A5120AFAAA is a high-displacement RE 505 Series motor on a 6-hole mount, built for heavy fixed installations where both sustained high torque and overpressure protection are required. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. With 748 cm³/rev displacement and 9,400 in-lbs continuous torque, this motor pulls hard at very low shaft speeds, and its 1,750 psi relief valve protects the motor and system when load spikes threaten to exceed safe operating pressure. This motor also replaces 500750A3120AFAAA.
