Hydraulic Gear Pumps and Hydromotors

IHI hydraulic pumps and motors are particularly well suited to mobile equipment applications; they are designed for extreme duty cycles, and continuous heavy-duty operation. Whilst the equipment is of a simple yet rugged design, it is manufactured to extremely precise tolerances.
Pumps are available in capacities ranging from 11 cc٫ rev to 200 cc٫ rev for each gear section. Several sections can be combined into one assembly. A wide selection of SAE and ANSI mounting flanges and drive shafts are available for all drive units. Pipe thread, O-ring seal, and split flange ports are available in both metric and SAE standards.
• IHI’s full range of gear set products comply with the international standard, ensuring the metallurgical elements of Molybdenum and Nickel are present in the base material for premium quality requirements necessary in hydraulic gear pump applications.
Multiple pump units: Several pump sections can be combined in a single drive to eliminate multiple drive P.T.O units.
Precision matched gears: All gears are manufactured from high alloy forged bars, surfaces are precision finished and each gear pair is matched for maximum efficiency. The deep 10-tooth pattern gives maximum output per revolution whilst ensuring low pulsation frequency.
Bearings: Heavy duty roller bearings are utilized on all gear journals to reduce wear caused by contamination.
Motors: are available with capacities ranging from 0.75kw to 75kw. Basically similar in design to pumps, they are engineered for extreme heavy duty applications, with high efficiency characteristic.
Motor speed is in direct proportion to the volume of oil delivered to the inlet port and output torque is in proportion to the pressure supplied to the motor. All other equipment required to match our pumps and motors is readily available.
