9.16 Maintenance and repair
Maintenance and repair work on the pump should only be carried out by trained service personnel, who
should have read and understood this manual prior to installing, operating or servicing this equipment.
Inform operating personnel before starting maintenance and repair work. Protect all plant parts and
operating media connected before and after the machine, such as compressed air and hydraulics, against
unintentional start-up. In all maintenance, inspection and repair work, switch the machine off and secure
the main switch against unintentional start-up.
Secure larger assemblies carefully to lifting gear. Check loosened screw connections for firm seating. Use
only original spare parts.
After maintenance work is finished, check the safety devices are functioning.
Bearings maintenance
Note: Remove the bearing housing only to replace or adjust the shim ring. Do not attempt to
dismantle the power end of the pump or replace the bearings. Pumps needing repair, servicing,
new bearings or other work on the power end must be returned to MasoSine for attention. Special
training is available. Please contact MasoSine for further information.
