Chongqing TOP Oil Purifier Co., Ltd. is one of the most reliable manufacturers and suppliers of vacuum pumping set in China, also supports customized service. Please feel free to buy advanced vacuum pumping set made in China here from our factory.
Products Description
The ZKCC pumping set pairs a Roots booster and rotary vane pump on a single skid to pull the vacuum levels required for transformer drying, oil degassing and industrial vacuum work. One operator can wheel it between workstations, and the automatic pressure control lets it run overnight without supervision.

Features
- The matched pump combination reaches 5×10⁻² Pa ultimate vacuum at a pumping speed of 70 L/s, pulling a medium-sized transformer to the required level within 30 to 60 minutes. This means one set can handle multiple units per shift without holding up the production or service schedule.
- A digital vacuum gauge shows real-time chamber pressure so the operator confirms the set point at a glance before oil filling or insulation testing begins.
- Once the pressure threshold is set, an automatic vacuum relay starts and stops the pumps as needed. The set runs unattended through overnight drying cycles, cutting labour hours and avoiding the energy waste of continuous pump operation.
- At 65 dB(A) the set can work in a test bay or lab without disturbing nearby stations. The skid frame and castors let one person move it between transformer assembly bays, storage areas and loading docks, eliminating the need for dedicated vacuum plant at each position.
Application Scenarios
- Transformer, capacitor and switchgear factories evacuating equipment before oil filling. A consistent, verified vacuum prevents moisture trapping inside insulation, which would otherwise lower breakdown voltage and shorten service life.
- Field service teams performing on-site transformer drying during outages. One mobile set can cover several substations, removing the capital cost of fixed vacuum installations at each location.
- Industrial workshops running batch vacuum drying, distillation or coating processes where repeatable vacuum levels directly affect product uniformity and rejection rates.
