Gardner Denver Vacuum Pump VC 200

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.

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.

Enter the current operating hours of the vacuum pump

Is the oil level at the upper edge of the sight glass?

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.

Only vacuum pump oils as per DIN 51506-VDL, ISO 6743-3 DVA and DVC or a synthetic oil released by Elmo Rietschle may be used.

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.
