Internal Gear Pump Single Pump HG0 HG1 HG2 HG Series

Features

Adopting axial and radial pressure compensation design to maintain high volumetric efficiency even at low speed and low viscosity.

Ultra-low noise, using high-strength cast iron and a unique internal noise reduction design, making the noise lower.

Very low flow and pressure pulsation, and stable flow and pressure output can still be maintained at low speeds.

High pressure design, the maximum working pressure can reach 35MPa.

Wide speed range, the highest speed can reach 3000r/min.

Can be combined to form a double pump.

Insensitive to oil pollution and long service life.

It can be widely used in hydraulic systems in industries such as plastic machines, shoe machines, die-casting machinery, and forklifts, and is especially suitable for energy-saving systems driven by servo inverters.

Structure

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).
