End of life
Due to the repetitive compression cycles the hose will
eventually break down. A hose failure can be detected
by looking at the lubricant fluid level inside the pump. If
the fluid level is far above the lubricant level as
indicated on the inspection window this is an indication
for a hose failure.
After a hose failure the pump should be stopped and
thoroughly cleaned. See the product manual for the
cleaning- and hose (de)installation instructions.
2.5
Hose failure detection
If a hose failure occurs you should immediately stop the
pump. It is strongly advised to use a high level float
switch to make sure the pump stops after a hose failure.
See the product manual for additional details or contact
your Bredel representative.
For procedures on removing the hose, cleaning
instructions and installing the hose, refer to the pump
product manual.
2.6
Hose disposal
After use the hose should be disposed in accordance to
the local laws applicable for rubber articles. In case of
doubt contact your Bredel representative.
WARNING
After a hose failure it cannot be guaranteed
that the pumped fluid has only been in
contact with the hose.
