Locating blockage in Series-Flo systems
Locating blockage
If any blockage exists in a Trabon Series-Flo system it is caused by one of the
following reasons:
All servicing and disassembling should be carried out under the cleanest conditions possible.
A blockage will be centrally signalled by a pressure gauge, pressure switch,
controller or by the pump relief indicator, exhausting lubricant. Before proceeding
as outlined make a visual inspection of the system and check for crushed lines or
improper divider valve installation. Verify that each divider valve outlet required to
discharge lubricant can do so and that no pipe plugs have been installed in an outlet
designed to serve bearing or another divider valve.
Use filtered lubricant only!
Note!
Dirt and foreign material are the worst enemies of any lubricating system!
