Armstrong has published a free eight-page energy saving guide which identifies various upgrade options and their paybacks. Scenarios range from simply replacing a belt-driven pump with a close-coupled alternative (requiring no pipe changes and offering a payback period of around three years), right up to replacing the pump with a new high efficiency unit (which requires pipe changes but offers payback periods within two years).
Each scenario suggests the types of existing system for which it might be suitable (naming specific legacy pumps) and explains the necessary pipe changes. Results include pump curves and other charts, and estimated savings.

Meanwhile, following successful completion of the British Pump Manufacturers' Association's recent PSAT course, Armstrong's aftermarket sales director, Peter Wolff, is accredited to carry out independent assessments to the standards laid down by the American Society of Mechanical Engineers (ASME) - the EA-2 - 2009 standard for Energy Assessment of Pumping Systems.
