Gardner Denver Vacuum Pump VC 100

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

Switch off the motor and ensure 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.

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.

If you are going to use another oil type, empty the oil removing device housing and oil cooler completely.

Was the oil completely emptied?

Enter the amount of oil refilled

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)

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

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

Check the pipes and screws for leaks and to ensure they are seated properly and if necessary seal again or tighten up.

Check the terminal box and cable inlet holes for leaks and if necessary re-seal.

Clean the ventilation slots on the machine and the motor cooling ribs.

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.

Sign off on the Intake Air Filter Maintenance

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 (Fig. 7/L) every 2000 operating hours or when the filter resistance is 0.7 bar (see pressure gauge ➝ Accessories, Checking with short term, atmospheric suction) because it is not possible to clean them.

Check if the filter resistance is 0.7 bar

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

Check if the discharged medium is heavily contaminated

Changing: Undo the air oil removers (Fig. 7/L) with a ring spanner (spanner width 19 mm or 3/4”) rotating counter clockwise.

Check if the air oil removers are undone

Insert new air oil removers with the open lock symbol (see Fig. 8) with the arrow ▼ on the insert and fix turning clockwise (until it clicks into place).
