Sumitomo Hydraulic Internal Gear Pump QT23-4 Features:

1.Special gear design, low noise, stable audio frequency under high-speed operation

2. Wear resistance under high-speed operation, simple mechanical structure, the high-grade hydraulic oil is used to reduce abrasion of the machinery surface and functional parts.

3. QT pump can be under high-speed operation at 250bar, it is not easy to cause abrasion of parts by using the common hydraulic oil.

4. Low pressure fluctuation, QT pump can prevent pressure wave, so it is an ideal machine with precise speed control and low noise, QT internal gear pump with smooth contact of the internal gear, mute operation

Japan-Sumitomo Internal Gear Pump

(Sumitomo is mainly engaged in injection molding machine, die casting machine, oil press, hydraulic pump (variable pump, vane pump, gear pump), QT internal gear pump (antiwear hydraulic oil viscosity 40cst (ISOVG32 oil, oil temperature: 50℃), revolving speed: 1500r/min, inlet pressure: 0MPa)
