1, ultra-low noise performance: the noise value is very low, even if the pressure or speed increases the noise value is almost unchanged;
2, excellent durability: gear sliding with forced lubrication, very wear-resistant;
3. Low pulsation: almost no pulsation of 0.2mpa;
4, a very wide range of USES: can be a single pump, double pump, used for industrial purposes.
Gear pump QT series:
1. Low-pressure pump: maximum pressure 8Mpa, flow rate 10-250cc/rev; Used for precision machining machinery;
A. Power refers to the power required under the condition of instantaneous maximum working pressure. B. When the working speed n is not equal to 1500r/min, the driving power can be calculated according to the approximate formula "table value * n/1500" to obtain its approximate value. C. Can be combined into a double pump.
2. Medium pressure pump: maximum pressure 16Mpa, flow rate 5-125cc/rev; Mainly used in general industrial machinery, injection molding machine;
3. High pressure pump: maximum pressure 32Mpa, flow rate 5-125cc/rev; Used for stamping machine tools and other industries.
