1. The tank body is subject to strict overall pickling and anti-corrosion treatment, and coated with special anti-corrosion non-toxic water tank paint, which has good anti rust performance;

2. The domestic first-class vacuum pump is adopted, which has good lubrication, low oil consumption, low noise, large suction force and long suction range, so as to ensure the reliable use of the suction and discharge system;

3. It has three functions of vacuum suction, pressure discharge and gravity discharge. The pipeline design is novel and advanced, which is convenient for installation and maintenance, and greatly simplifies the operation;

4. An anti liquid overflow device controller is installed at the top outlet of the tank. When the liquid reaches the rated range, the floating ball of the controller immediately closes the vacuum pipeline to prevent the liquid from overflowing into the vacuum pump and affecting the normal operation of the vacuum pump.
