A. sumitomo gear pump has the following characteristics:
1. Ultra-low noise performance, smooth contact of internal gear of gear pump in QT, and continuous rotation of mute. Gear pumps feature special gear designed for extremely low sound when used, even at high speed, the audio is smooth and even.
2. High operation and wear resistance. In addition to simple mechanical structure, the use of advanced hydraulic oil can reduce wear on mechanical surfaces and functional parts. QT gear pump can run at high speed with 250bar pressure. It is not easy to wear out the parts even using ordinary hydraulic oil. The extremely low pressure pulsating QT gear pump can almost completely avoid pressure wave, so it can be used as an ideal mechanical tool for accurate speed control of the system.
B. There are three kinds of gear pumps with a wide range of pressure: high pressure, medium pressure and low pressure.
1. Low-pressure gear pumps, such as qt41-63f /A (qt31/41/51/61 series)
2. Medium-pressure gear pumps, such as qt52-f /A (QT22/QT32/QT42/QT52/QT62 series)
3. High-pressure gear pumps, such as qt63-100f /A (QT23/QT33/QT43/QT53/QT63 series).
