If there is the danger that the operating

agent may present a hazard in any way due

to decomposition of the oil, or because of

the media which have been pumped, you

must determine the kind of hazard and

ensure that all necessary safety precauti-

ons are taken.

We can only guarantee that the pump ope-

rates as specified by the technical data if

the lubricants recommended by us are

used.

Maintenance

3.2 Oil Change

For proper operation of the pump, it is essential that the

pump has an adequate supply of the correct and clean

oil at all times.

The oil must be changed when it looks dirty or if it

appears chemically or mechanically worn out (see Sec-

tion 3.1.1).

The oil should be changed after the first 100 operating

hours and then at least every 2,000 to 3,000 operating

hours or after one year. At high intake pressures and

intake temperatures and/or when pumping contaminated

gases, the oil will have to be changed more frequently.

Further oil changes should be made before and after

long-term storage of the pump.

If the oil becomes contaminated too quickly, install a dust

filter and/or oil filter (see Section 1.3).

Only change the oil after the pump has

been switched off and while the pump is still

warm.

Required tool: Allen key 8 mm.

Remove the oil-drain plug (9/4) and let the used oil drain

into a suitable container. When the flow of oil slows

down, screw the oil-drain plug back in, briefly switch on

the pump (max. 10 s) and then switch it off again. Remo-

ve the oil-drain plug once more and drain out the remai-

ning oil.
