The design of HF series low-pressure spiral gear pump has the most leading technical advantages in China. The spiral teeth, shape and tooth surface are completely meshing, and the flow of the fluid is stable and no pulsating. From the structural design, the root cause of noise has been eliminated - pressure fluctuations, no trapped oil phenomenon, modular design can be selected in a variety of configurations, especially suitable for the use of media with high viscosity and high gas content.
