Safety instructions for maintenance
For normal operation, the maintenance of 5 to 21 m
3
/h series pumps only require
regular oil changes (
see Operating instructions
).
Insufficient tightness after servicing could result in chemical hazards. Always
perform a leak test after maintenance.
Certain gases can become corrosive and toxic after decomposing when
trapped in oil. Always wear protective gloves when handling used and
dirty pump oil, drain it into a closable container, and do not breathe the oil
fumes. Always use fully self-contained breathing apparatus.
During pump removal, draining or maintenance operator could be in
contact with process residues which could cause severe injury or death.
Ask your safety department for instructions according to the local
regulations.
We recommend:
- To purge the pumping installation with dry nitrogen.
- To wear gloves, protective glasses, breathing mask or any appropriated
safety equipment.
- To ventilate the premises well.
- Not to eliminate maintenance waste via standard disposal channels. Have
it destroyed by a qualified company if necessary.
- To install the inlet and exhaust blanking plates, these accessories are
delivered with the pump.
