5.2 Shimming the shoes
Suitable shimming of the shoes lengthens the service
life of the hose.
5.2.1 SERVICE PRESSURE SPECIFIED AT ORDER
If the service pressure has been specified at order, the
pump is shimmed in the factory to allow pump running at
specified service pressure. No additional shimming is
needed.
5.2.2 SERVICE PRESSURE NOT SPECIFIED AT ORDER
OR MODIFICATION OF THE OPERATING PRESSURE
OR THE TEMPERATURE OF THE PUMPED PRODUCT
If the service pressure has not been specified at order,
the pump is pre-configured by the manufacturer for a
service pressure up to 5 bar (72,5 psi).
For higher pressure value, one or more removable shims
must be placed under the shoes. Similarly, for using the
equipment at a lower service pressure, one or more
removable shims should be removed from below the shoes.
The number of removable shims to be added to the pre-
shimming shims is specified in the table below.
Before modifying the shimming of the pump, check
that the equipment (motor and pump) is compatible
with the new operating conditions.
5.2.3. PUMP NOT PRE-SHIMMED IN THE FACTORY (KIT)
OR MODIFICATION OF THE DRIVE SPEED
The pre-shimming operation must be performed/updated
in the following cases :
• installation of a pump delivered as a kit (wheel not
installed),
• replacing the shoes,
• modification of the drive speed of the pump.
Refer to the Instructions 1101-Q00 SETTING THE HOSE
