The world meals and beverage sector is under growing pressure to clean up its act and guarantee its operations are as environmentally friendly as potential. Pumps type an integral part of manufacturing so how are they serving to meet difficult government legislation?
Ambitious targets continue to be set in meals and beverage manufacturing – for instance in the UK, the Food and Drink Federation and the British Beer and Pub Association have each pledged to achieve internet zero carbon emissions by 2040 across manufacturing sites and their supply chain.
This is in a sector which is the fourth highest industrial energy person within the country based on a government report. Fans and pumps accounting for 12% of food and drinks sector emissions and, in accordance with the Carbon Trust, a completely loaded motor consumes its personal purchase cost in electrical energy in 30 to 40 days of continuous running.
With pumps, a direct energy saving can be made by utilizing extra environment friendly motors corresponding to an IE3 drive which may be retrofitted to current technology. But motor alternative is only a half of the answer that pumps can deliver to manufacturing.
Ultimate aim
The ultimate aim is a lean manufacturing operation realising optimum product yields while using fewer resources and, critically, a healthier bottom line.
Vipul Mistry, global product leader for diet and health, pumps at SPX Flow based mostly in the US, said: “Energy consumption is on the top of customers’ minds so designing more efficient pumps is vital.
“The whole value of ownership for the customer must be optimised for their specific course of covering reliability, effectivity and productivity and keeping downtime to a minimal.
“For example, when utilizing positive displacement pumps for viscous media we now have to make sure there is much less slip in the course of by way of the way we design inside clearances to maximise effectivity which is important for the preservation of the product.”
SPX Flow has greater than 25 innovation and design centres worldwide, providing support from food technologists, product specialists, course of and manufacturing engineers, electricians and other consultants working immediately with customers.
“We stay related to clients, fixing problems and offering solutions to ensure their processes are attaining optimum performance and sustainability,” added Mistry.
New challenges
For example, new challenges for pumps in the meals and beverage trade embrace processing of plant-based meals similar to vegan cheese in response to consumer demand and producers flip to manufacturers to supply the specific expertise required in areas including pressure and viscosity.
Logically, the more viscous the media, the extra energy might be required to course of it. Significantly, UK-based Watson-Marlow Technology Group’s Masosine division’s sine pumps aren’t affected by viscosity in the same method as lobe pumps and require decrease torque to drive them so can use smaller motors.
The sinusoidal rotor produces powerful suction with low shear, low pulsation and mild dealing with of a broad range of viscous merchandise without modification to the pump and with minimal impact on power requirements. Continuous move ensures up to 50 per cent less energy utilization in contrast with different pump types.
Smaller pumps are naturally more power efficient however care have to be taken to make sure they are as much as the duty. However, a US-based fruit juice producer was capable of choose small sine pump instead of a bigger lobe pump to transfer frozen fruit juice concentrate leading to an US$11,000 saving in electrical energy costs in addition to slicing annual CO2 emission by 33,880kg.
Product restoration
Meanwhile, according to French manufacturer Mouvex, financial savings created by product recovery far outstrip any vitality saving initiatives. It claims cost savings can be as much as 32 times larger than the yearly price of the power needed to run the pump. In a big manufacturing operation, that can lead to hundreds of thousands of dollars of savings per yr.
If a pump can’t strip suction or discharge manufacturing traces then there is a major environmental impact with more power, water and chemical substances required for cleansing along with higher levels of disposal of wastewater and residue.
Traditional pumps similar to lobe and exterior circumferential piston (ECP) pumps, for instance, do not possess the flexibility to clear strains whereas they also put on inflicting product slip and waste from leaks in seals.
Mouvex’s eccentric disc technology can pump air when no fluid is present making a vacuum impact on the pump’s suction facet and a compressor effect on the discharge aspect. So once the product has been discharged, air is pumped to push out the product “plug” for restoration.

For example, at a Coca-Cola HBC production plant in Hungary, unloading viscous orange juice concentrate from trucks was proving time and power consuming while also inflicting issues with cavitation. A Mouvex SLS pump lowered unloading time by two hours with increased product recovery and energy financial savings.
Plant maintenance manager Zoltan Marincsak stated: “We reduced waste from 300 kilos to 100 kilos – with six unloading’s per week, it’s multiple tonne and saves us thousands of euros.”
