Characteristics of Sumitomo QT gear pumps and common models

Thread Content

Features of the Sumitomo QT gear pump: Ultra-low noise performance. The internal gear contacts of the QT internal gear pump are smooth, ensuring silent operation. Its outstanding feature is its special gear design, which results in extremely low noise levels during operation; even at high speeds, the sound remains smooth and quiet. In addition to a simple mechanical structure, high operational wear resistance is achieved by using high-quality hydraulic oil, which helps to reduce wear on the mechanical surfaces and various functional components. The QT pump can operate at high speeds under a pressure of 250 bar, and even with ordinary hydraulic oil, it does not easily cause wear to the components. The extremely low-pressure pulsating QT pump virtually eliminates pressure waves, making it an ideal mechanical tool for precise speed control of systems. The wide pressure range is as follows: 1 The power value refers to the power required under the condition of the highest operating pressure. 2 When the operating speed n ≠ 1500 r/min, the drive power can be approximated using the formula “value in the table × n/1500”. 3 can be combined to form a double-pump unit. Features: 1 Low noise, with maximum noise level below 65db(A). 2 Long lifespan. 3 Good resistance to pollution. 4 Low pressure pulsation. 5 Strong self-priming ability. 6 It is widely used in various hydraulic systems. 【Anti-wear hydraulic oil viscosity 40 cSt (ISO VG32 oil, oil temperature 50°C), speed 1500 r/min, inlet pressure 0 MPa】Common models of Sumitomo QT gear pumps: Umitomo QT32-12.5, Sumitomo QT32-16, Sumitomo QT42-20, Sumitomo QT42-25, Sumitomo QT42-31.5, Sumitomo QT52-40, Sumitomo QT52-50, Sumitomo QT52-63, Sumitomo QT62-80, Sumitomo QT62-100, Sumitomo QT62-125, Sumitomo QT31-20, Sumitomo QT31-25, Sumitomo QT31-31.5, Sumitomo QT41-40, Sumitomo QT41-50, Sumitomo QT41-63, Sumitomo QT51-80, Sumitomo QT51-100, Sumitomo QT51-125, Sumitomo QT61-160, Sumitomo QT61-200, Sumitomo QT61-250, Sumitomo QT33-12.5, Sumitomo QT33-16, Sumitomo QT43-20, Sumitomo QT43-25, Sumitomo QT43-31.5, Sumitomo QT53-40, Sumitomo QT53-50, Sumitomo QT53-63, Sumitomo QT63-80, Sumitomo QT63-100, Sumitomo QT63-125.
