Advice on specifying a food transfer pump

08 June 2020

With fluids varying from shear sensitive creams, to viscous, solid laden sauces to high temperature vegetable oils, the process of specifying a food transfer pump requires technical knowledge to make sure that you have the right pump to deliver your process without downtime.With 10 years’ experience supplying food processing plants, dairies and breweries, Castle Pumps Ltd can help. 

Food and drink manufacturing plants rely on pumps throughout the production process; for dosing specific quantities of ingredients on the line, transferring the finished product into containers and removing any waste product leftover. With fluids varying from shear sensitive creams, to viscous, solid laden sauces to high temperature vegetable oils, the process of specifying a food transfer pump requires technical knowledge to make sure that you have the right pump to deliver your process without downtime. With 10 years’ experience supplying food processing plants, dairies and breweries, this is something Castle Pumps Ltd can help you with and the proof is in the pudding…

Castle Pumps received an enquiry from a food manufacturer in the UK who wanted to increase the volume of spaghetti bolognese production on site. In order to make the process more efficient, they required a pump to transfer the hot, viscous bolognese sauce containing meat solids from a drum, to move it quickly from production to packaging.

This application meant several key requirements had to be fulfilled by the pump:
• Safe for hygienic food handling
• Capable of handling a viscous product containing soft solids
• Suitable for drum emptying

The customer had two additional requests that also needed to be fulfilled:
• That they could control the speed of sauce delivery
• That they could use a nozzle to dispense it into containers. 

The right pump for the process
Due to the product being for human consumption, the pumping solution of course needed to be food grade and easy to clean. We chose an eccentric worm food grade barrel pump approved to FDA and 3A standards, with the body and connections of the tubeset all manufactured of electro polished stainless steel (316 Ti). This pump model is designed with minimal areas for food to congregate, and can easily be stripped down in no time for cleaning and/or sterilisation. 

This specific  food grade drum pump is from the positive displacement family of pumps, meaning that it can generate the pressure required to move the viscous, bolognese sauce with little shear, preventing the meat solids from being churned into a slurry.  

To fulfil the additional requirements from the food manufacturer, we supplied the pump with a variable speed drive, allowing the operator to adjust the motor as they please to run at the capacity required to meet the specific delivery requirements, and a bespoke food grade T piece. This T Piece, which included a pressure relief valve, allows the fluid to be circulated back to the tank to prevent the pump from working against a dead head when the nozzle is closed, which can result in damage to the pump.

The end result was a bespoke food grade pumping solution supplied to the customer within 5 weeks of order placement, enabling them to meet their objective of quicker bolognese production.
