HYDRAULICS 28 HYDRAULICS & PNEUMATICS January/February 2018 www.hpmag.co.uk Old pumps not only consume too much energy, they are also prone to failure which can adversely affect your maintenance budget and in turn your business. By replacing them with new, correctly sized, energy-efficient pumps, users can enjoy reliable, low-cost pump operation. As a way of helping pump users to undertake that all- important pump selection, the British Pump Manufacturers Association (BPMA) has developed a comprehensive online Pump Selection Search Facility, which is available for anyone to use. This online search facility can be readily accessed via the existing BPMA website http://www.bpma.org.uk/pump- search/1/Pumps and is completely free of charge. How to use The Pump Search There are two ways for users to search for the perfect pump and its supplier: Search One: You know the type of pump you need If you know the type of pump you are looking for, click on the Pump Type drop-down menu, select your Pump Type then click Show Results. This will offer a list of BPMA members who will be able to supply this type of pump. Search Two: You know the application, but not the pump type If you are not sure of your Pump Type, but know what it will be used for, click on the Pump Application drop-down menu, select your application and then click Show Results. This will offer you a list of BPMA members who can supply pumps suitable for that particular application. If your initial search delivers a large number of potential suppliers, it can be further refined by selecting extra parameters from the options available in the left-hand column, which include Head, Flow, Drive Type, Material etc. Only BPMA members are displayed on this search engine and all BPMA members have agreed to adhere to the BPMA Code of Conduct, so you are assured of high quality, fully compliant, energy efficient pumps on every selection. www.bpma.org.uk BPMA aids pump selection Drive specialist Bonfiglioli has extended its range of wheel drive with the introduction of the new 600WT drive series, which includes a new axial piston motor designed especially for agricultural equipment.
