HPI

Brand reference:75425

HPI was established in 1966. In 1970, it developed the world's largest gear pump, 250cc/rev. In 1983, it developed gear pumps and gear motors with a proportional compensation system and bidirectional rotation, CIP 3G. In 1985, it developed electric hydraulic power units for automotive steering systems (Renault Super 5). In 1994, it became a member of the SMI Koyo Group. In 1998, HPI took over ENERFLUX. In 2000, a new factory in Blois was established. In 2005, it developed a fan cooling system driven by a hydraulic motor with directional rotation capability. In 2006, the JTEKT Group was established through the merger of Koyo Seiko and Toyota Machine Works in 2006-1. HPI joined the JTEKT Group, becoming JTEKT HPI. In 2007, it developed the third-generation hydraulic power unit capable of mounting cylinders. JTEKT HPI officially took over T.F.I. In 2011, it developed hydraulic power units for stackers. In 2013, business expanded to Asia: China, South Korea, and India. In 2016, JTEKT HPI celebrated its 50th anniversary and developed silent hydraulic power units for electric pallet trucks.

German HPI pump HPI model HPI price

HPI pumps are rotary pumps that transport liquids or increase their pressure by relying on the change and movement of the working volume formed between the pump cylinder and the meshing gears. Two enclosed spaces are formed by two gears, the pump body, and the front and rear covers. When the gears rotate, the volume of the space on the disengaging side increases from small to large, creating a vacuum that draws in the liquid. The volume of the space on the meshing side decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure at the discharge port of the gear pump depends entirely on the magnitude of the resistance at the pump outlet. HPI pump structural features 1
