2.50 Intake And Discharge Provision
2.51
The vacuum regulator and vacuum dial gauge is attached to the collection jar. The vacuum regulator
allows the vacuum level to be set between roughly atmospheric pressure and the maximum vacuum
allowed for the pump model. The collection jar and hydrophobic filter keeps water from accidentally
being drawn into the unit. The regulator allows discharge pressure to be set between atmospheric and
the maximum possible for the pump model. Model 2511 is equipped with a pressure port.
Note: Adjusting the vacuum regulators will affect the performance of the pump.
WARNING
Never block the discharge port. If the exhaust is blocked, pressure will build-up
in the pump above its rated operating pressure.
Be sure to call Welch technical service prior to start up at 847-676-8800 if you have any questions.
