Hydraulic gear pump

IGP Hydraulic Internal-Engaging Gear Pump is suitable for situations requiring low noise, high pressure, stable running and compact design, such as in plastic injection machines, blowing machines, vulcanization machines, bending machines and cutting machines. It is also used in steering wheels, deck cranes, as well as vehicle loading/unloading devices, lifting equipment and other hoisting machinery.

Mechanism & Features
When the internal-engaged gear set rotates, the fluid is sucked into the pump casing and the cavity between the inner and outer gears, whilst the bigger and smaller crescents and the engaged teeth form seal in the circumferential direction at all times due to the action of the spring plate and the supporting tray forms an almost gapless seal in the axial direction, thus minimizing the pump's volumetric loss and the sucked fluid is transferred from the tip of the teeth towards between the teeth and is ejected from there at a high pressure.

The internal engaging of the gear set, the slide bearing, the automatic compensation in both axial and radial directions, are all good guarantees for the unique and illuminated features of this pump, namely high pressure, low pulsation, low noise and compact design.
