3.6.1 Additional Routine Maintenance – Atex units.
Grease
-
Check for any signs of lubricant leakage on startup.
-
Check for any signs of overheating.
Low maintenance gearbox, factory filled with EP 00 semi-fluid grease. The
grease should not require replacement during the lifetime of the bearings or
until 14,000 hours of operation.
Oil
-
Check oil levels on startup.
-
Check for any signs of overheating.
-
Change the oil every 6 months or 1500 operating hours, whichever is
the sooner.
For lubricant capacities and grades refer to section 5.3.
After 14000 hours of use, the pump will need a general overhaul and it will
need to be re-certified for use within the Atex environment.
A general overhaul must include a full disassembly of all components and the
following work carried out.

Clean all pump components

Examination of all components for damage/wear

Replacement of all taper roller bearings

Replacement of all elastomeric components

Replacement of all seals, radial seals, and Gamma rings
The general overhaul must be carried out by qualified personnel in a specialist
workshop with the appropriate equipment. Re-certification must then be
carried out.
We highly recommend that the general overhaul is carried out by Wright Flow
