Gardner Denver Vacuum Pump VC 50

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, replace if necessary.

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

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 number of operation hours since the last oil change.

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

Check if the viscosity of the oil complies with ISO VG 100 as per DIN 51519.

If the oil is subject to high temperatures (ambient or intake temperatures over 30°C, insufficient cooling, 60 Hz operation etc.) the oil change interval may be extended by using the recommended synthetic oil.

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

Enter the current hours of operation

Was the oil changed at operating temperature?

Was the oil completely emptied?

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

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

Enter the filter resistance in bar

If the filter resistance is 0.7 bar or more, replace the oil separator elements

Successfully removed the air oil removers with a ring spanner?
