the pump, the regulations of the "Additional operator's manual and assembly
instructions" as well as any additional documents of the order-related pump
documentation regarding the performance of inspection and maintenance work must
be strictly observed.
Danger of explosion!
- The maintenance of the pump units must be carried out in a non-
explosive environment or in an area without existing explosion
hazard.
- When maintaining the pump units, an explosive atmosphere inside
the equipment must be excluded by the operating company.
- For pump units with electric motors or geared motors, the control
cycles, change intervals and lubricant qualities described or
required in the "Additional operator's manual and assembly
instructions" as well as in the documentation of the motors and
geared motors used must be strictly complied with.
- Wear parts, such as mechanical seals, shaft seals, bearings and
gear units, must be checked regularly and replaced if necessary in
order to ensure permanent explosion protection.
- Control, monitoring and checking devices must be maintained in
accordance with the manufacturer's instructions, and checked
regularly for functionality.
Maintenance: Bearings and bearing seals
- Check running noises, vibration and temperature of gearwheels and
bearings on a daily basis.
- Check the oil level daily. When the pump is at a standstill, the sight
glass must be filled to the middle.
- Daily visual check of seat and for damage and leakage on radial
shaft seals, V-rings and lip seals. Replace if necessary.
- Lubrication intervals, oil changes, and replacement intervals of the
bearings must be strictly observed in accordance with the
specifications of the "Additional operator's manual and assembly
instructions" or the order-related documents.
Maintenance: Shaft seal, sealing system and seal
- Regular check for inadmissible leakage at the shaft seal.
- Assembly, disassembly and most maintenance work on the pump
unit must only be carried out with the electrical connections
disconnected.
