Watson-Marlow Fluid Technology Group (WMFTG) has produced a white paper that sets out how Mee (MasoSine energy efficiency) curves can be used as a powerful and proven tool for demonstrating that sine pump technology is able to deliver significant benefits for users in the food and beverage sector.
High viscosity? Even better
Many engineers in food and beverage plants are faced with pumping highly viscous products, ranging from frozen orange juice to cheese curd. Here, viscosities can register in the thousands, or even millions of centipoise (cP). Easy-to-use Mee curves show clear evidence that sine pumps require up to 50% less power than lobe or circumferential piston pumps, particularly when pumping viscous products. In fact, the curves are able to demonstrate that the higher the viscosity, the more the savings.
Further benefits of sine pumps include low net inlet pressure requirements and minimised potential for cavitation. In addition, the significant savings in electricity consumption mean a greatly reduced carbon footprint.
All of these facts can be evidenced using Mee curves, which were first developed by WMFTG due to the inherent energy efficient characteristics of sinusoidal technology. The curves help identify the correct size of pump and drive, and thus save money for the customer. They show how many kilowatts of power are required for a motor to run a particular application (relative to varying viscosities), as well as the efficiency of the pump.
Vast savings potential
The achievable energy saving is a very important factor. According to the BPMA, an average of two-thirds of the electricity cost on a typical industrial site will be spent on running electric motors. In addition, energy represents 95% of a pump’s life cycle cost, so the opportunities for savings are simply too good to ignore.
The WMFTG white paper sets out in clear language the ways in which food and beverage plants can leverage the latest sine pump technology to realise sizeable savings and rapid ROI. It addresses technical factors such as net inlet pressure requirements, net positive suction head requirements, cavitation, power requirements and the effects of viscosity. Importantly, it also shows how to use Mee curves, and the measurable outcomes that are possible in comparison with lobe pumps, for example.
Case study evidence
In a recent survey by the Food and Drink Federation of 100 decision makers at UK food and beverage plants, three-quarters said that coping with rising energy bills has affected their decision to expand. Clearly, the need to save energy has never been greater.
To illustrate what can be achieved using MasoSine pump technology, a selection of interesting and relevant case studies, focussing on products such as fruit juice concentrates, are included in the white paper. These show the annual savings in both electricity and carbon emissions. The latter is increasingly important in a business world where green supply chains are becoming the expected norm, rather than the exception.
