Peristaltic pumps simplify moving apple pie mix

Watson-Marlow Bredel Pumps product story

The introduction of hose pumps to an apple pie mixing and food processing plant has made production faster and completely eliminated the need for seals, valves and manual handling of products
A manufacturer of traditional baked foods is achieving improved process efficiencies and extended profit margins thanks to the installation of peristaltic technology.
Engineers at the manufacturer were tasked with introducing a modern method of transferring food mixtures that would minimise damage to the product and reduce the amount of manual handling required.
Following consultation with the Watson-Marlow Bredel food applications specialists, the company opted for SPX hose pumps.
The low-shear design of the SPX range of hose pumps allows the manufacturer to protect the contents of its pies, in this case apple chunks, thereby safeguarding its reputation for quality foodstuffs.
Other pumps can damage the product by using impellers, vanes, lobes or valves.
"We have a lot of peristaltic pumps" stated the project engineer tasked with implementing the upgrade.
"They are the best method of getting the job done.
The SPX hose pumps simplify transferring the apple mix from the mixing bowl to the depositor hopper.
Unlike other pump types, they provide a low shear transfer method, which was one of our main considerations".
The company initially considered diaphragm and volumetric pumps for the new apple pies, but opted for the protection offered by Watson-Marlow Bredel hose pumps.
"We needed a big transfer pump, so we originally tested diaphragm pumps.
They were not suitable because they became blocked by the apple mix".
The Watson-Marlow Bredel hose pumps are designed to suit the stringent requirements of the food industry.
They are self-priming and dry running and require no seals or valves and the fluid is totally contained within the tube (it is therefore separated from the pump).
No other positive displacement pump offers this unique separation of pump and fluid.
