Key points
An industry leading pump manufacturer says that the requirement to meet the UK Government’s ESOS (Energy Savings Opportunities Scheme) presents manufacturing and process plants with a real chance to invest in future competitiveness
Watson-Marlow Fluid Technology Group points out that plants viewing ESOS as a needless tick-box exercise are either ignoring or unaware of the numerous cost, performance and quality benefits that could be available.
ESOS came into force on 17 July 2014. In essence, the scheme is a mandatory energy assessment and energy saving identification scheme for large undertakings and their corporate groups.
Some 14,000 enterprises are affected in the UK, all of which have to file an energy audit delivered by one of around 500 registered auditors, no later than 5 December 2015 or risk fines ranging from £5000 to £50,000.
Energy audits
ESOS Energy Audits have the potential to increase businesses profitability and competitiveness by identifying cost effective savings which, if implemented, will improve energy efficiency.
Although there is no obligation to implement the recommendations that arise from the audit, plants that pass up the opportunity are ignoring the chance to improve their bottom line.
The scheme is estimated to lead to £1.6 billion of net benefits to the UK. According to UK government figures, plants implementing the suggested changes will make back some 13.5 times the initial investment.
Pump efficiency
Among the technologies set to offer the biggest rewards in relation to ESOS audits, are pumps. According to the BPMA (British Pump Manufacturers’ Association), pumps account for no less than 10% of the world’s electricity consumption, and two-thirds of pumps use up to 60% too much power.
With this in mind, ESOS auditors are likely to check the age, condition and size of any pumps installed to get an indication of the scope for savings. A subsequent recommendation would be to perform a specific assessment of the pumps to check their efficiency.
It is estimated that pumping system improvements can deliver up to 40% reduction in energy costs, possibly even more in the case of viscous fluids. Typically, the torque required to drive a pump increases in line with viscosity, thus resulting in the need for large electrical motors.
Larger motors draw more power, even when not operating at capacity. The BPMA says that on industrial sites, an average of two-thirds of the electricity cost can be attributed to running electric motors.
Smaller motors
The good news is that SineTMpumps are not affected by viscosity in the same way as lobe pumps and circumferential piston pumps. As a consequence, they can use smaller motors, a factor that has made them popular choices in the food, beverage and cosmetics industries, as well as in the chemicals and pharmaceuticals sectors. Ultimately, sine pumps offer up to 50% less energy consumption for the same flow, compared with other pump types.
To help show the benefits of the latest sine pump technology, Watson-Marlow is offering plants a free trial of MasoSine pumps to assess the efficiency gains available, first hand. It is hoped the move will help those affected by ESOS to make the right decisions moving forward.
Watson-Marlow can also provide a set of calculations, known as Mee (MasoSine Energy Efficiency) curves, which show the potential reductions in energy consumption, and how energy savings rise in line with viscosity.
Ahead of the curve
Mee curves have been developed from extensive research as a tool to 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.
For those interested in finding out more, Watson-Marlow is publishing a paper that outlines why Mee curves are a useful and proven way of demonstrating that sine pump technology can deliver significant user benefits in comparison with competing technologies. The paper will be published Autumn 2015.

About us
Watson-Marlow Fluid Technology Group (WMFTG) peristaltic tube and hose pumps meet requirements including: value for money; low cost of ownership; reliability and ease of maintenance to the food and beverage, chemical, pharmaceutical, mining and many other industries.
We demonstrate how pumps deliver significant process efficiencies over the lifetime of the equipment. Whether performing flavouring addition in food processing, chemical metering in water treatment or mineral recovery, we have a solution which can cut pump downtime and reduce costs through higher accuracy metering and transfer. WMFTG has dedicated application engineers available to help customers make the right pump and tubing choice from a range providing microlitres per minute to 80 cubic metres per hour flow rates.
The only part of the pump to come into contact with the product is the tube or hose. This means there are no seals or valves that can wear or fail. Replacing the tube or hose can be performed quickly and safely. Peristaltic pump benefits include:
Total fluid containment with no seals No ancillaries Handle viscous and abrasive slurries and sludge Self-priming capability Dry running without damage to the pump In addition to their range of positive displacement pumps, Watson-Marlow Fluid Technology Group has added PTFE-lined chemical and industrial hoses to their range. Aflex hoses are reinforced to withstand the most severe conditions and use.
Where we supply to
Europe, Africa, Asia, Australia, South America, North America
Industries we supply to
Automation, Chemicals, Consultants, Components Electronics, Energy and Power, Food and Beverage, Glass Ceramics Cement, Metals and Minerals, OEM, Paper and Pulp, Pharmaceutical Cosmetics Toiletries, Plastics and Rubber, Recycling, Textiles, Tobacco, Water and Wastewater
