Internal Gear Pump
Internal gear pumps are very versatile. These pumps are often used on thin liquids such as solvents and fuel oil. Still, they are also ideal in the petroleum, chemical, paint, dye, food, grease, and pharmaceutical industries.
In addition to their wide viscosity range, the internal gear pump also has a wide temperature range. The single point of end clearance which is adjustable, allows the pump to accommodate high temperatures, maximize efficiency for handling high-viscosity liquids, and accommodate for wear.
The internal gear pump is non-pulsing, self-priming, and can run dry for short periods. The bi-rotational design allows the pump to be used to load and unload vessels. With the simple structure of only two moving parts, these pumps are reliable, simple to operate, and easy to maintain.
- Unique design of axial and radial pressure compensation maintains high volumetric efficiency even at low rotation speed and low viscosity
- Ultra-low noise. High-strength cast iron and unique noise-deduction design to prevent the noise
- Extremely low flow and pressure pulsations, maintaining stable flow and pressure output at low speeds.
- Designed for high-pressure applications, with a maximum operating pressure of 25-35 MPa
- Wide speed range, maximum speed up to 3000 r/min
- Can be assembled in a duplex pump
- Non-sensitive to oil and grease pollution, long service life
- Widely applied in the hydraulic system in plastic moulding machines, shoe machines, die-casting machines and forklifts, especially suitable for a frequency conversion servo energy-saving system
