To satisfy demand for hydraulic pump capacity on engines, Transfluid offers the Stelladrive pump drive family. The drives provide up to 550 hp (410 kW) and eight pads and offer a high capacity flywheel and flywheel housing for mounting PTOs, hydraulic pumps, compressors, and transmissions. Stelladrive is comprised of two standard design types, the SPD and the MPD. The SPD pump was designed for engines producing less than 413 lb·ft (560 N·m), has a single pump tower, and is available with input and output housings. Suitable applications include small cold planers and pump sets as well as a class of generators that improve utility by providing an auxiliary drive for hydraulic pumps and compressors. The MPD family is applicable on engines producing up to 4650 lb·ft (6305 N·m) and offers two towers with four pump pads. Typical applications include rock crushers, grinders, chippers, drill rigs, and pump sets.
