Eternal Hydraulic QT Sumitomo Type Internal Gear Pump
QT internal gear pump is a high-performance internal gear pump with high pressure, widely used in servo system and other hydraulic systems. The QT line with a long-term world-wide proven track record was improved once again with structural alterations. A specially designed gearing geometry reduces the noise level and allows the quiet operation even with high pressures and rotational speeds. Eternal Hydraulic provide complete pumps and accessories that can replace Sumitomo originals.

Application of QT Internal Gear Pump
Sumitomo QT series hydraulic internal gear pump is widely used in injection molding machines, precision industrial presses, forging machinery and elevators and other mechanical equipment.
Features
1. low noise performance
The QT series internal gears are smooth and mute, and their excellent features are specially designed for gears. The sound is very low when used, and the sound is still smooth even at high speeds.
2, high running wear resistance
In addition to the simple mechanical structure, the use of advanced hydraulic oil can reduce the mechanical surface and the wear and tear of the functional parts. QT chestnut can run at high pressure 320bar pressure, even if the use of general hydraulic oil, it is not easy to wear pieces.
3, very low pressure pulsation
QT pump can almost completely remove the pressure wave, it can be used as the system precision control of the ideal machine tool pressure
