| Features: With the oil circulation and rotary blade design, the lubrication of the cylinder is ensured, resulting in the stability and reliability for prolonged operation. The direct coupling of the motor with the pump renders a small dimension of the machine, making it potable and easy to set up. The enclosure of the pump is made of cast aluminum alloy, and the cylinder of the pump is made of anti-friction cast iron that makes the machine strong and durable. The parts and components are made with precision equipment such that degree of the vacuum of the pump is consistent over the time with less noise and vibration. The inside of the pump adopt the exhaust protective equipment and fixed oil-seal, thus there is no leakage and splitting. An oil return protection device is equipped within the air inlet nozzle, to prevent the counter flow of oil. Plug for power supply has been provided. Thus the machine can be put into operation after being unpacked. The structure is rational and the design is beautiful and appealing to the normal taste. |
