Project Description


Rotary Vane Vacuum Pump

  • The 2XZ series rotary vane vacuum pump belongs to two stage direct connection structure rotary vane vacuum pump, which can be used for drying, sealing the container and other ancillary pumping air or net vacuum equipments.
  • It has the advantages of small size, light weight, low noise, convenient for using and more.
  • The 2XZ series rotary vane vacuum pump can not be used as the compression type delivery pump

2XZ-series industrial grade dual-stage vacuum pumps are designed for reliable long time continuous operation. They have a balance between low cost and high performance.

They come with gas ballast, which is designed to allow purposefully pull a less deep and slower vacuum by opening the gas ballast, allowing dry air to go directly into the pump and diluting the vacuum pull, and it also helps keep moisture, solvent, and other contaminants from getting stuck in the pump, and instead passing through to the exhaust. The built-in check valve prevents pump oil backflow.

We offer all necessary fittings (KF25 clamps and hose barb connectors, etc) and a high capacity exhaust oil mist filter which also returns trapped pump oil back to the pump and makes the pump quieter to run.

It is important to note that pumps should always be ran in a well ventilated area.

  •  it can be a separate role, can also be used as various types of high-vacuum system of the pre-pump and pre-pump.
  • the inlet continuous open air operation, shall not exceed three minutes.
  • the pump does not apply to the extraction of metal corrosive, the chemical reaction of the oil from the pump, containing dust particles of gas to the body oxygen is too high, there is explosive gas.
  • the pump has to be used for compression pump or pump.
  • working environment: temperature 5 ℃ -40 ℃ range, the relative temperature is not greater than 90%, inlet pressure less than 1333Pa under the conditions allow long-term continuous operation.
  • the installation of the power supply, according to the provisions of the motor tag wiring, motor rotation should be noted that the direction of the arrow on the bearing the same direction.
  • continuous pumping container pipe, the diameter should not be less than the pump inlet diameter, and the pipe should be short and less elbow, while paying attention to pipeline leakage.
  • before each start focusing on the oil level to stop the pump oil to the oil standard glass diameter of 4/5 height is appropriate.
