Rollers and shoes are the rotating components in peristaltic pumps, they are two different designs for different application types. Although different, both operate in a very similar manner. The shoes/rollers are connected to a shaft from the motor/gearbox, these rotate at a low speed and squeeze the hose inside the pump to force the fluid round.The roller design has the main benefit that far less lubrication is required for the hose, however the pump is limited to a maximum pressure of 8 bar. Other benefits of the roller design include; • Longer hose lifespan, energy savings up to 30% compared to a shoe pump design.• Easier maintenance (there is no need to drain lubricant from the pump and then to refill again, less mess).• Any product leakage is 100% recoverable from the drainage port (lubricant from a shoe pump can mix with the leaked product and is then not recoverable).The shoe design requires the hose to be submerged in large quantities of lubricant, however the pump can achieve pressures up to 15 bar.Both designs are available with the same types of inlet/outlet connections and accessories such as variable speed drive and leakage sensor. The best solution for you is entirely dependent on the application, fluid and flow rate/pressure requirements.
