Direct-drive radial-piston motor

The Hydre-Mac direct-drive radial-piston motor handles variable-speed applications. The low-speed, high-torque motor, featuring a cam-lobe design, employs a MacTaggart Scott heavy-duty motor design. The motor increases component life with two inlet and outlet ports that reduce pressure drops at high power; generating less heat overall. A symmetrical 18-piston/roller assembly eliminates piston side loading and reduces wear and tear. Hydre-MAC’s repairable wear surfaces include shaft seals, wear rings, piston seals, and bearing pads that can be replaced on-site.
