Peristaltic Pumps
The Proof is in the Pudding !
A bakery and confectionary goods producer contacted Castle Pumps looking for some pumps to help them move away from the manual handling of some of their ingredients , and upscale their production .
They required a pump for transferring the fillings of their doughnuts and apple fritters , as well as a model for dosing vanilla essence and other flavourings . It wasn ’ t long before it became clear that peristaltic pumps were the perfect choice !
The beauty of the peristaltic design is that its inner tube is the only part that encounters the fluid . Not only does this make it simple and low cost to maintain compared to other pump technologies with multiple wearing parts such as impellers and seals and bearings , but it also makes it highly versatile in terms of the fluids it can handle .
Why did peristaltic pumps “ rise ” to the occasion ?
For the doughnut and fritter filling , an AMP peristaltic pump with an inverter was supplied . The addition of the inverter was important to allow the bakery to adjust the speed of the motor when being used with the fillings of differing viscosities . For example , when pumping the more viscous jams , the motor speed needs to be slowed considerably compared to when transferring the apple pulp .
Due to there being a single wetted part as previously mentioned , there are no valves to clog or impellers to jam . This design means that the peristaltic pump can easily handle the apple chunks and stringy solids present within the fillings without damage or downtime to the bakery ’ s process . Infact , peristaltic pumps ’ solid handling capabilities are only limited to the diameter of their internal hose , meaning if it fits , it can usually be pumped !

The beauty of the peristaltic design is that its inner tube is the only part that encounters the fluid .
When it came to the dosing of the flavourings , Castle Pumps specified a DS-M peristaltic dosing pump . This model has excellent accuracy even at low flow rates , making it ideal for handling small volume transfer and highly precise quantities .
For both models , Castle Pumps specified a food grade thermoplastic internal hose and tri-clamp connections for a smooth , non-contaminating pipework joint , ensuring that the pumps are safe for handling products for human consumption .
Getting the wrong pump for your food grade process can result in inconsistency in the finished product , crushed solids , clogging , excessive wear , loss of productivity , waste of costly product or at worst , contamination . Always trust technical experts to specify the
right pump for your application .
