7.5 Hose failure
Cause of a hose failure
The hose in a peristaltic pump has to withstand many
load cycles of considerable magnitude. The repetitive
stress cycles will cause the hose to deteriorate and
eventually fail.
Result of a hose failure
A hose failure will result in direct contact between the
pump lubricant and the pumped fluid.
Consequences of a hose failure
In general, this will not cause a hazardous situation
because the Bredel Genuine Hose Lubricant is
harmless (approved by the United States Food and
Drug Administration). However, there is an exception in
case of pumping a strong oxidiser or a strong acid.
