Innovation the lifeblood of Calpeda pumps Product development is the lifeblood of any portfolio but, in the case of Calpeda, they have totally embraced the principle with innovative new products constantly coming on stream. Two of the latest introductions are the GQS 40 submersible pump range and e-idos plug-andplay energy-efficient packaged booster sets. The GQS family of submersible pumps for dirty water now includes the GQS 40 model which, alongside GQS 50, extends the range to cover lessdemanding applications. It still delivers the ultimate performance, combined with reliability and affordability. GQS 40 pumps are ideal for nonaggressive domestic and industrial waste water; for draining flooded areas or emptying tanks; for extracting water from ponds, streams and rainwater collection tanks; and for irrigation. Features include a double mechanical seal on the shaft, triple impregnated dry windings for greater resistance to humidity, a relief valve and free-flow impeller (vortex). As for booster sets featuring several pumps in parallel,

energy savings, design simplicity and system cost containment make them more sophisticated than ever. With Calpeda e-idos pumps, this aspect has been greatly simplified. e-idos pumps are supplied already equipped with a pressure sensor so pressurisation groups can be created without having to add control panels, and without needing to wire any connection. The pumps used only need to be hydraulically connected and, apart from performance excellence, this also helps keep the system pressure constant. By programming each pump at start/stop set points, they

operate in cascade mode according to the increases in flow rate and the falls in pressure, making for automatic duty cycling. In the event of power failure, the pump set resets automatically. For engineers designing pump system solutions, configuring the product before purchasing it, choosing the model and selecting optional accessories needs to be just a few clicks away. The Calpeda online pump selector tool is designed to do just that, but to also offer additional advice, guidance and an interactive knowledge resource to help with system design. It is not intended as a replacement for direct contact with Calpeda’s technical team, more as a complementary tool that allows individuals to autonomously find the most suitable pump for a particular application 24 hours a day, from wherever their location. “With digitalisation now underpinning the whole process of building services engineering, solutions providers such as ourselves need to be dynamic and forward looking,” says Graham Fay, Managing Director, Calpeda Ireland. “Hence our commitment to product development, and even more so of the nature of the innovations we constantly bring on stream.” Contact: Graham Fay, Calpeda Ireland.
