HG Series Single Hydraulic Internal Gear Pump
l Axial & radial pressure compensation design
l High volumetric efficiency at low speeds/viscosity
l Ultra-low noise (high-strength cast iron + internal noise reduction)
l Minimal flow/pressure pulsation
l Stable output even at low speeds
l Max working pressure: 35MPa
l Wide speed range: up to 3000r/min
l Combines into double pumps
l Oil contamination resistant, long service life
l Ideal for plastic machinery, shoe-making machines, die-casting equipment, forklifts
l Perfect for servo inverter-driven energy-saving systems
The HG series hydraulic pump is a backlash compensation internal gear pump with a fixed displacement.
lts basic composition is: front cover (1), pump body (2), rear cover (3), gear shaft (4), ring gear (5), sliding bearing (6), front and rear side plates (7) and positioning Rod (8), and the radial compensation function composed of the crescent sub-plate (9), the crescent main plate (10) and the plastic rod (11).

1.Working medium
Petroleum-based mineral oil with a viscosity range of 10-300mm/s can be used. ISO VG46 anti-wear hydraulic oil is recommended.
2.Working temperature
The working temperature range is -10℃-100℃. In order to ensure long-term reliable life, the best working temperature range is 20℃-80℃.
3.Cleanliness control
The cleanliness level of the control system oil is required to be no more than 9 (NAS 1638) or 17/14 (ISO 4066).
4. Pump installation
When connecting the shaft and the motor, use a flexible coupling as much as possible to avoid bending moment or axial thrust. The maximum allowable coaxiality error between the shaft and the motor shaft is less than0.15mm.
5. Inlet pressure and piping
Allow the absolute pressure ofthe suction port to be 0.2-2Bar. The reasonable piping diameter should not be smaller than the oil suction port of the pump to ensure an average oil suction speed of 0.6-1.2m/s.
6. Import and export connection
Try to avoid hard connection of steel pipes in and out of the oil pipes. Rubber hoses are recommended to avoid additional noise caused by additional loads.
7.Exhaust
Before the first operation, the pump should be filled with oil or an exhaust valve should be added to remove the air in the pump and the system pipeline. If there is air residue in the pump or pipelinelt will cause the vibration and noise of the pump, and indirectly affect the service life of the pump.
8. Maintenance
In order to improve the service life of the pump, the system should be regularly checked for abnormal vibration, noise, oil temperature, whether there is bubble formation in the oil tank, and whether there is leakage and other problems, and timely maintenance.
