Sumitomo QT hydraulic pressure Gear Pump is widely used in injection molding machines, forging machinery and elevators and other mechanical equipment.

QT hydraulic pressure Gear Pump 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
