Adjust The Compression Force (Shimming) - Bredel 40-100 Operating Manual

8.9

Adjust the compression force (shimming)

Fitting and removing shims is a simple action which can be carried out via the inspection window on
the front of the pump housing. The pump hose or the pump cover does not need to be removed.
In order to determine the correct number of shims for your specific application Refer to "Shims
specifications" on page 96.
CAUTION
Too many shims, this means a too high compression force on the pump
hose, create a too high load on the pumphead and pump hose, which
results in a reduction of the life of the pump hose and bearings.
CAUTION
Too few shims, this means a too low compression force on the pump hose,
create a loss of yield and slip or backflow. Backflow results in a reduction
of the life of the pump hose.
