Troubles related to water/steam exhaust

Troubles related to the exhaust of water and water vapor

When a large amount of water and water vapor are exhausted by an oil rotary vacuum pump.

  • The pressure may be bad or the exhaust time may be longer.
  • Water accumulates inside the pump, causing rust and abnormal wear of parts.
  • The pump may break (lock).

Recommended pump to solve the problem

ULVAC recommends
the Dry Vacuum Pump GR Series.

It can be evacuated with water vapor without liquefying!
In other words, you can eliminate the trouble of water.
