VacUUM Pumps

MAINTENANCE: The Vacuum Pump requires occasional flushing. Remove the pressure gauge and run ¼ cup of flushing solvent (GAST AH225 or equivalent) through the pump. If the pump fails to produce a vacuum when it is first turned on, a brief warm-up may free the blades and restore the normal functioning. The initial inspection should be performed at 500 hours.

LUBRICATION: the automatic oiler should be refilled as needed with the proper oil. Use a high detergent automotive engine oil with a viscosity equivalent to SAE 10 or less.

AIR FILTER: Clean the air filter regularly by removing it from its holder and washing thoroughly in the solvent. Replace the dried out filters.

CONNECTIONS: Be sure all connections between primer and pump are tight.

BEARINGS: Bearing life is dependent upon pump application, proper lubrication, proper cooling and general operating conditions.

VANES: Vane life is affected by general operating environment and such factors as pump speed, vacuum levels and duty cycle.

INSTALLATION:

• If you are using the Pump separately: This unit and its solid base should be anchored to a shelf, floor, or another piece of machinery.
  
• To save time and avoid inconvenience, position the unit to provide an easy access to all lubricators, filters, and mufflers.
