Bakery opts for a jam-proof pump

23 May 2024

When a bakery and confectionery goods manufacturer needed a pump for transferring apple pulp for the filling of its apple fritters, it quickly became apparent that a peristaltic pump would provide the best solution.

The design of a peristaltic pump results in the inner tube being the only part that comes into contact with the fluid being pumped. This makes the solution simple and low cost to maintain when compared to other pump technologies which will feature multiple wearing parts such as impellers and seals and bearings. A peristaltic pump is also highly versatile in terms of the fluids it is able to handle.

With no valves to clog or impellers to jam, a peristaltic pump – in this application, supplied by Castle Pumps –is easily able to handle the apple chunks that are present within the filling without damage or downtime to the bakery’s process. Indeed, the solid handling capabilities of peristaltic pumps are only limited to the diameter of their internal hose, meaning if it fits, it can usually be pumped.

For this application Castle Pumps suggested the use of a food grade thermoplastic internal hose and tri-clamp connections for a smooth, non-contaminating pipework joint, ensuring that the pump is safe for handling products for human consumption. 

While primarily being used for apple pulp for the filling of apple fritters, the addition of the inverter supplied allows the speed of the pump to be controlled which may be required if the pump is required to handle other, thicker fluids on site, such as jams.
