Gardner Denver Vacuum Pump VCX 300

NOTICE: Property damage due to insufficient maintenance! If the air oil removal devices are strongly polluted, their functioning will be reduced, which can cause machine failures.

Check de-oiling elements for soiling at regular intervals.

Enter the filter resistance. Replace de-oiling elements if the filter resistance exceeds 700 mbar.

Do not clean the de-oiling elements. Always replace the de-oiling elements by new ones.

NOTE: For monitoring the level of soiling of the de-oiling elements, we recommend using a pressure gauge (ZDM). This enables a check of the filter resistance with temporary atmospheric suction.

The air oil removal devices (4x) may be contaminated with particles of dirt when the machine has been running for a long time (power consumption and pump temperature increase). Reduce the change intervals accordingly depending on how contaminated the discharged medium is.

Switch the machine off, secure it against accidental switching on and vent to atmospheric pressure. Let the pump cool down.

Unscrew air oil removal elements with a ring spanner (width across flats 19 mm) counter-clockwise.

Push in the new air oil removal elements and screw in clockwise. Tightening torque: max. 15 Nm Thee air oil removal elements shall be flush with the oil remover housing.

Switch off the machine and secure it against accidental switching on

Vent the pump to atmospheric pressure and let it cool down

Open the catch of the oil filling point (Fig. 7/H)

Open the oil discharge point (Fig. 7/K) and completely discharge the used oil

Close the oil discharge point (Fig. 7/K)

Fill in new oil through the oil filling point (Fig. 7/H)

Check the oil level in the sight glasses (Fig. 7/I)

NOTICE: Property damage due to bad lubrication! If the oil level is too low, this can cause damages to vacuum pump.

Check oil level every day and, if necessary, refill oil.

Check the oil level in the sight glass (Fig. 2/I) at least once daily.

To refill the oil, switch off the machine and bleed to atmospheric pressure. See chapter 7.6.1 “Refilling of oil”

The vacuum pump must regularly be checked for dust deposits and cleaned, if necessary. The cleaning interval depends on the operational requirements.

a) Clean the vacuum pump with a dump cloth or using a vacuum cleaner. Remove dust deposits:

• Between the cooling ribs of the motor

Cleaning can also take place in connection with the cleaning of the oil cooler. See chapter 7.8.
