Permco® is the industry-leading manufacturer of high-pressure hydraulic gear/vane pumps and motors, flow dividers, intensifiers, and accessories. Established in 1964, the Perfection Machining Company initially designed and manufactured replacement parts for the mining industry. After it was renamed Permco four years later, this family-owned business developed a wide array of replacement hydraulic parts. Eventually, it expanded its manufacturing capabilities to include cast iron parts and the resulting complete units. Today, Permco focuses more on customer service while continuing its decades-long tradition of developing and manufacturing fluid power systems that meet customers' needs. Permco's product offering now includes flow dividers, intensifiers, gear and vane pumps/motors, and a variety of truck parts and accessories.
