GRUNDFOS says today the Grundfos Product Center (GPC) is well-known as the ‘go to’ pump selection tool of choice for an increasing number of industry professionals. This could be because much thought and consideration went into its design to deliver an online tool that would make choosing the right pump solution as straightforward as possible. The company says this ease of selection is also true when a replacement pump is required. Simply log onto the Product Center and select the REPLACEMENT option on the home page. From here, enter the name of the old pump into the Quick Search field or alternatively, you can enter the pump name and other data into the Classic Search field. The Product Center will then display the top three replacement pump choices and you can filter your selection by choosing either the pump with the lowest purchase price, the pump with the lowest energy consumption or the pump with the lowest total lifecycle costs. This then offers the option not just to simply replace, but to e-place by selecting the most energy efficient options. Grundfos says additional requirements, such as fluid type, lifecycle costs and evaluation criteria provide additional filtering options and will ensure that finding the best pump replacement choice is there waiting for you, whenever you need it. w | www.grundfos.co.uk Thanks to their unique, seal-less design, Hydra-Cell pumps are able to operate at exceptionally high efficiency levels, claims WANNER INTERNATIONAL… And higher efficiency translates directly to ‘lower energy costs’. The Hydra-Cell pump drive mechanism is submerged in a reservoir of oil, which keeps it permanently lubricated and allows power to be transmitted through the drive train with minimal frictional losses. With no dynamic seals in the pumped liquid to further consume energy, industry leading pumping efficiencies as high as 85% minimise Hydra-Cell’s power requirements. This compares with around 45-50% pumping efficiency for a typical multi-stage centrifugal pump and, as a result, Hydra-Cell pumps can frequently be fitted with smaller motors than would be needed to meet the same flow and pressure requirements. t | 01252 816847 e | Brenda@wannerint.com w | www.hydra-cell.co.uk Pumps for high efficiency During 25 years of providing solids pumping and mixing solutions to numerous sites in the UK and Ireland, P&M PUMPS says it has met the demands of some of the most varied, large scale and interesting applications and a good example of this is the recent supply of 2 self- priming Vaughan Chopper pumps to replace 2 dry-dock sump scavenge pumps in Aberdeen Harbour. The existing scavenge pumps, originally installed to provide a duty of 600gpm at 35ft head, including a 7” suction lift, were failing due to problems of blockages. The solution was to replace the existing dual macerator and sump scavenge pumps with progressing cavity pumps, specifically Vaughan Chopper Pumps with motors rated at 18.5kW at 1470 rpm, 415V/3ph/50Hz. t | 01487 830123. e | matt@pumpmix.co.uk w | www.pumpmix.co.uk Chopper pumps solve pumping problems SENSATA TECHNOLOGIES a leading supplier of sensor, industrial control, power management and electrical protection solutions, has announced it has published a new white paper that shows how new technology water pumps with pressure sensors are meeting the needs of 21st Century living. Distributing water on a large scale has been a challenge that the world has tackled for decades. It is a particular challenge in high-rise buildings. The white paper looks in particular at how ‘old technology’ water pumps that tend to operate at full speed or not at all are being replaced by Variable Speed Pumps (VSP) that use a Variable Frequency Drive (VFD) or Variable Speed Drive (VSD) to continuously optimise the pump speed and power consumption while maintaining constant outlet pressure of the pump. w | www2.sensata.com/water E-place your pumps New technology water pumps 40 | Plant & Works Engineering www.pwemag.co.uk July/August 2019 Energy, the Environment & Water By Karl Lycett – RITTAL UK’s product manager for climate control: Winter may have been the focus of the hugely popular TV drama Game of Thrones but in the real world the mercury is rising and we will soon be firmly into summer. Despite any rainclouds that may still be lingering, don’t be fooled. Summer will bring higher temperatures, which may be good for the weekend BBQ, but it doesn’t bode as well for your electrical equipment. At this point in the year, the alarms on your cooling units will probably still be non-existent which means you’re spending less time maintaining overheating panels. However, this is the ideal time to start considering your climate control, to understand what changes or improvements need to be made.
