GRUNDFOS OPTIMISATION SERVICES asks “which assessment is right for you?” and continues: Pumps are at the heart of your facilities. Day in and day out, pumps make your business run, but they come at a price. Not so much to purchase, but in the daily operation of the pump. In fact, 85% of the total costs of your pumps relate to the energy used to run the pumps - and there is money to be saved. An Energy Check of your pumps can provide a solid foundation for saving 30-50% on the operational costs of your pumps. Any installation with old, over-sized, inefficient or unsuitable pumps is likely to hide this kind of savings – and the Energy Check helps you discover the potential. Grundfos offers a number of different energy efficiency assessments: Energy Check, Energy Check Advanced, Pump Audit and Thermo Dynamic Testing. The company says if you want a quick assessment of the typical savings that can be made by upgrading to high efficiency pumps on one or more of your pumps, then the Grundfos Energy Check is a good place to start. With an advanced energy check it can monitor the energy and performance characteristics of every pump in your facility at once, this can often provide wider benefits than just energy monitoring, often highlighting problems with valve performance and incorrectly specified pumps. t | 01525 850000 e | grundfos-uk@sales.grundfos.com w | www.grundfos.co.uk Pumps of all shapes and sizes can be looked upon as the beating hearts of the UK wastewater treatment process, especially when recurring storm events lead to increased volumes of rag and debris entering the system. VAUGHAN CHOPPER PUMPS offers uninterrupted pumping even in the most challenging, arduous conditions and there is a growing list of success stories to prove this. An ongoing example of reliable pumping performance with VAUGHAN is at Thames Water Banbury. As it was back in June 2006 a 10” Vaughan SP10R, the only auto self-priming chopper pump on the market, was installed in the RAS (Return Activated Sludge) line at Banbury. It was the first of its kind to be used in the UK and was replacing one of 4 existing old style, extended shaft axial flow pumps. However, when rag and solids content became more and more evident failures were common due to continual blockages. As floor space in the pump house was restricted a powerful, yet compact pump set was required and the SP10R with an over/under drive configuration and its suction line simply dropped approx. 3m down the existing axial flow discharge line, with no down well fittings, was installed in 2006. It has been operating 24/7 for almost 13 years at the Banbury site with a reported flawless performance and no requirements to unblock or inspect the pump. With this success a second SP10R was soon installed. t | 01487 830123 e | matt@pumpmix.co.uk w | www.pumpmix.co.uk Pumps prove to be the solid solution Which assessment is the right one? 32 | Plant & Works Engineering www.pwemag.co.uk February 2020 Energy, the Environment & Water HADLEY GROUP has announced that following the move of Hadley Steel Framing to its Oldbury site, an extension to scope of the existing ISO 14001:2015 Environmental Management System registration has been completed and successfully audited by the UKAS accredited Steel Construction Certification Scheme. The scope of registration is: ‘The manufacture of cold roll-formed metal sections and allied products, including the design and assembly of steel framing systems’ which now covers the site activities of both Hadley Group - Building Products Division and Hadley Steel Framing. ISO 14001 certification was originally achieved by Hadley Group on its Oldbury site in February 2010. The latest extension to scope further demonstrates Hadley Group’s continuing commitment to determine its environmental aspects, reduce impacts and maintain legal compliance through the application of ISO 14001:2015 the International Environmental Management Systems Standard. w | www.hadleygroup.com/about-us/environment- sustainability Achieving ISO 14001:2015 Certification On a recent Yorkshire Water contract J N Bentley of Skipton was faced with the complexity of replacing approximately 25m of a 350mm diameter rising main pipe at Whitby, which was situated within a shaft. J N Bentley employed PMP Utilities of Burnley to install the rising main after using WINN & COALES (DENSO) SeaShield 80 system to provide protection from the sea water. To make the installation easier the SeaShield 80 was applied to the barrel lengths of the pipe prior to lifting the 25m long pipe into place. PMP Utilities then applied the system to the bolted flanges in-situ. SeaShield 80 System comprises Denso S105 Paste, Denso Marine Piling Tape, Densoclad Tape and Denso SeaShield Smart Band. Densyl Mastic was also used to profile the joints. t | 020 8670 7511 e | mail@denso.net Protecting marine-side rising main
