Sub-zero Drinks Dispensing

The vending machine industry is an established user of peristaltic tube pumps but an installation in sub-zero temperatures demonstrates the benefits of the design particularly well. In cold climates, chocolate syrup used by a vending machine to make a cup of hot chocolate becomes highly viscous. So, to deliver the correct measure, in hygienic conditions and at a consistent flow rate the OEM chose a bespoke peristaltic tube pump. In this case a dovetail section silicone tube was specified that is suitable for high temperature fluids.

Peristaltic tube pumps with high suction capability are readily available. Standard models will lift a liquid, such as water, by as much as 8.5 mt. However, for this vending machine application even greater suction was required. This was achieved without altering the flow rate by fitting a modified autoclavable cartridge to the pump.

These Features Make Peristaltic Pumps Ideal for Heavy Duty Applications

In summary, although the attributes of the peristaltic pump makes it the prime candidate for heavy duty applications, it brings other benefits that greatly extend its scope. Its combination of seal-less design, low maintenance, gentle pumping action, high suction life, abrasion resistance, reversible operation and ability to run dry gives this technology the edge for a multitude of tasks.
