OPERATION

•
Hazardous situations
•
Additional downtime
Hose failure will result in additional downtime,
because you must clean the pump before a new
hose installation.
•
Large spill of product
In case the pressure in the process line
(reservoir) is above the pressure in the pump
housing (ambient pressure), the process fluid
can enter the pump housing. If there is no check
valve in the process line a serious amount of
fluid can flow from the reservoir into the pump
housing and escape through the breather onto
the floor. This could lead to a large spill of
product outside the pump. Reversed flow
protection is advised. This is not part of the
scope of delivery.
WARNING
Avoid direct contact between a strong
oxidiser or a strong acid and Bredel
Genuine Hose Lubricant. This can cause
unwanted chemical reactions. Use an
alternative lubricant to avoid hazardous
situations. Contact your Bredel
representative for more details.
Regularly replace the hose to avoid hose
failure and additional downtime. Hose life
depends on the operating condition,
process fluid and hose material. The end-
user should be aware of this and establish
the frequency of preventive hose
replacement. Contact your Bredel
representative for advice.
