Gardner Denver Vacuum Pump VC 150 (20)

Warning: Always change the oil when the machine is at operating temperature and in an atmospherically ventilated area.

Notice: 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.

Enter the hours of operation since the last oil change.

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

Check the contamination level of the discharged medium.

Select the type of vacuum pump oil used

The viscosity of the oil must comply with ISO VG 100 as per DIN 51519.

Warning: This maintenance check requires trained personnel with PPE!

Clean the cooling coil by purging.

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 so, replace it.

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

Check the pipes and screws for leaks and to ensure they are seated properly

Check the terminal box and cable inlet holes for leaks

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

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 (spanner width 19 mm or 3/4”) rotating counter clockwise.

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

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.
