Gardner Denver Vacuum Pump VC 303

NOTICE: Always change the oil when the machine is at operating temperature and in an atmospherically ventilated area. If it is not completely emptied the amount that can be refilled is reduced.

The waste oil must be disposed of in compliance with the local environmental protection regulations.

Was the oil completely emptied?

Was the oil removing device housing and oil cooler completely emptied?

Enter the current hours of operation

The oil level must be checked at least once a day, if necessary top the oil up to the upper edge of the sight glass (Fig. 7/I)

Was the oil level checked today?

Was the oil topped up to the upper edge of the sight glass?

First oil change after 500 hours of operation. Subsequent oil changes after 500-2000 hours of operation.

Warning: This maintenance check requires trained personnel with PPE!

CAUTION: Defective coupling sprocket. Defective sprockets may lead to the rotor shaft breaking.

Switch off the motor and ensure that it cannot be switched on again.

Undo the screws on the motor flange.

Remove the coupling half on the motor side and the motor flange axially and suspend with a lifting device.

Check if the sprocket is damaged or worn. If yes, replace it.

Check the fan for damage from time to time and replace if necessary.

NOTICE: Frequent starting up and high ambient temperature. The service life of the sprocket is reduced as a result of this.

WARNING: Heavily contaminated air oil removing devices lead to increased pump temperatures and in extreme cases may cause the lubricating oil to ignite spontaneously.

Check if the oil separator elements are contaminated by dust particles

Replace these components every 2000 operating hours or when the filter resistance is 0.7 bar because it is not possible to clean them.

Enter the current filter resistance

Reduce the change intervals accordingly depending on how contaminated the discharged medium is.

Undo the air oil removers with a ring spanner rotating counter clockwise.

Insert new air oil removers with the open lock symbol with the arrow on the insert and fix turning clockwise.

NOTICE: Insufficient maintenance on the air filter. The power of the machine lessens and damage may occur to the machine.

Intake air filter: The micro filter (Fig. 4/f2) must be cleaned by rinsing out or purging or replaced more or less often depending on how dirty the discharged medium is.

Remove the cover (Fig. 4/G) after undoing the screws ( Fig. 4/s1)

Remove the suction flange (Fig. 4/D) after undoing the screws (Fig. 4/s2)

Check the function of the valve

For this purpose fit a shut-off device (enclosed volume min. 1 litre) on the suction side and starts vacuum pump shortly. Afterwards the vacuum achieved must remain constantly.
