Product Description

Product Introduction

1. Compact size, small footprint, corrosion resistant, and equipped with wheels for easy movement.

2. 7-inch touchscreen panel allows for setting parameters such as pressurization pressure, vacuuming pressure, pressurization time, and vacuuming water injection time.

3. Pneumatic quick-clamping, faster and more efficient than traditional hydraulic clamping, requiring no external high-pressure water source.

4. One-button start, one-button selection (manual or automatic), safe operation.

5. Suitable for mass production, used in conjunction with fully automatic Water Meter Test Benchs and automatic meter Meter Screwing Machines to improve production cycle time and increase capacity.

6. Low power consumption, energy-saving, requires only one operator, saving labor and time.
