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.
A high-level float switch can be applied to detect
fluid escaping through the breather. Refer to

WARNING
Avoid direct contact between a strong oxi-
diser 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, proc-
ess 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.
