The improved vacuum pump chamber can empty the air in the pipeline in a short time, achieving faster water outflow and higher priming; it also has the environmental advantage of zero oil contamination, with no need for oil refilling.

Ensures safe operation in extreme scenarios such as cold regions, tropical climates, and high-altitude areas.

Replaces the traditional mechanical panel with a liquid crystal panel. It not only enables one-click start-stop, lighting control, real-time viewing of working hours and equipment status, but also displays fault alerts simultaneously, making operation convenient even in dark environments.
