Internal Gear pump HG for Plastic Injection Molding Machine

1.The axial and radial pressure compensation design is adopted to maintain high volumetric efficiency even at low speed and low viscosity. The ultra-low noise is made by using high-strength cast iron and unique internal noise reduction design to reduce the noise

2.With extremely low flow and pressure pulsation, stable flow and pressure output can still be maintained at low speed. With high pressure design, the maximum operating pressure can reach 35 MPa.

3.The speed range is wide, and the maximum speed can reach 3000 r/min. It can be combined to form a duplex pump

4.It is insensitive to oil pollution and has a long service life

5.It can be widely applied to hydraulic systems in industries such as plastic machines, shoe machines, die-casting machines and forklift trucks, especially to energy-saving systems driven by servo frequency conversion

Detailed Description

This hydraulic pump adopts axial and radial pressure compensation structure, which effectively guarantees stable and high volumetric efficiency, even under low speed and low oil viscosity working conditions. It uses high-strength cast iron materials and a specialized internal noise reduction structure, greatly lowering operating noise to achieve ultra-low noise operation. The equipment features extremely low flow and pressure pulsation, sustaining stable flow and pressure output stably during low-speed operation. Built with a high-pressure structure, its maximum working pressure reaches 35 MPa. It supports a wide operating speed range with a top speed of 3000 r/min and can be assembled into a duplex pump for combined use. In addition, the pump has excellent oil pollution resistance, effectively reducing component wear and extending overall service life. It is widely applicable to hydraulic systems of plastic machines, shoe machines, die-casting machines, forklifts and other industrial equipment, and is especially suitable for servo variable-frequency driven energy-saving hydraulic systems.
