3.11. Shoe shimming – PT25 – PT80
During pump operation as the hose starts to wear, internal leakage inside the hose can occur. In
order to avoid this, additional shims can be added under the shoes in order to increase the
compression of the hose. This is an important procedure, as internal leakage reduces the hose
lifetime and affect the pump flow. The shoe shimming varies based on pump rotation speed,
discharge pressure and liquid viscosity. This operation can be done without complete pump
disassembly, through the sight glass.
NOTE! Proceed with this procedure only after familiarizing oneself with the instructions at the
beginning of chapter 3. Maintenance and all safety instruction in chapter 1.8. Health and safety .
