Pump Dismantling and Assembly.
Before undertaking any work on the pump the Shutdown Procedure should be
followed in section 3.5, and site safety practices must be observed.
While dismantling or assembling the pump it is essential to ensure that the
pump and/or components are secured to provide adequate stability.
Large pump components or assemblies should be lifted using suitable
devices. Use threaded holes for attaching lifting eyes where appropriate.
During dismantling or before assembly all components should be inspected for
fit, wear, and damage. If worn or damaged the components should be
replaced before re-assembly.
The position of all parts should be identified as they are removed to ensure
they are reinstalled in the same position.
Lipseals and o-rings are incorporated within the assembly. Regular inspection
and correct maintenance of these items will ensure that the lubrication is
sustained and the pump maximum working life is achieved. To ensure this, it is
extremely important that care is taken when removing and installing new o-
rings and lipseals. When removing and replacing lipseals ensure that the
location bore for the outside diameter and the seat for the back of the lipseal is
not damaged as this may create a leakage path.
When removing lipseals or o-rings care should be taken to avoid cutting
or tearing the sealing faces as they pass over splines, threads or other
potentially sharp or abrasive edges. All lipseals and o-rings should be
carefully examined and if damaged in any way, replaced on assembly.
All o-rings and sealing lips of lipseals should be lightly lubricated with a
suitable lubricant (silicon grease, etc.) before installing.
Prior to assembly, ensure all parts are clean and free from burrs or damage.
Where a vice is to be used, it should have protective jaws to avoid damage to
components. Do not apply undue force to install or position components.
All fasteners are required to be tightened to the required torque setting during
assembly, refer to section 5.2.
Bearing cones may be pressed into position providing the proper equipment
and procedures are employed to prevent component damage.
Under no circumstances should bearing cones or cups be hammered
into position.
For torque settings of fasteners and shaft rolling torque, see section 5.2.
