White Roller Stator Motor – 505750A5120AAAAA is a high-displacement RE 505 Series motor on a 6-hole mount with a straight keyed shaft — the standard-configuration variant at this displacement, built for heavy fixed-installation drives where the keyed connection locks the drive positively and no integral relief valve is required. Impro Fluidtek builds these motors on the same patents and manufacturing know-how as the original White Drive Products, acquired directly from Danfoss in 2022. With 748 cm³/rev displacement and 9,400 in-lbs continuous torque, this motor barely turns but pulls hard when the job demands maximum output without the overpressure protection of a relief valve. This motor also replaces 500750A3120AAAAA or 500750A5120ZAAAA.
