G type screw pump
G type screw pump
Single-screw pumps have been widely used in developed countries. Most of them are called single-screw pumps "Mono Pump" "MONOPUMPS", and Germany is called "eccentric rotor pump". Due to its excellent performance, its application range in China has also expanded rapidly in recent years. Its feature is the adaptability to the medium, the flow is stable, the pressure pulsation is small, and the self-priming energy is honest, which is not replaceable by any other pump. At present, the products of our unit have been self-contained, and the pressure is 0.4∽1.2MPa, which can meet the different needs of the users for single-screw pumps.
Main Feature
The single-screw pump is a new type of pump that works according to the principle of oscillating meshing volume. The transmission can be directly driven by a coupling, or transmitted by a low-speed motor V-belt, gearbox, stepless transmission and other devices. The flow rate is 0.8-150 m3/h, and the pressure is 0.4-1.2 MPa.

说明：
1、以上性能参数是常温清水试验时的试验数据；
2、对于不同的介质、不同的转速，性能参数都将变化，其流量值与浓度、粘度成反比，与转速成正比；
3、用户必须根据使用要求、输送介质的状况、选型原则选择泵的类型，或者和本公司技术部门协商来决定泵的类型。
4、对于水煤浆泵传动形式为齿轮调速配套电磁调速电机或机械无级变速电机，流量随转速变化无级可调。
