An ECS and FCS Collaboration Achieves Remarkable Success with Recently Tendered Environment Agency MEICA Framework Agreement
ECS Engineering wins Archimedes screw pump order for NI Water
Northern Ireland Water is investing over £3 million improving the water and sewerage infrastructure in the Bangor area. The project is designed to improve the operation of the existing network, reduce the risk of flooding and meet Northern Ireland Environment Agency standards for water quality. The first phase will be upgrade work at Luke’s Point pumping station, which will be equipped with two new Landy Archimedes screw pumps, supplied by ECS Engineering Services through trusted NI Water contractor Williams Industrial Services.
The existing screw pump arrangement at Luke’s Point has reached the end of its design life, and can no longer match the demands of the local population due to their limited pumping capacity. The current Archimedes Screw Pumps are rated at just 600l/s each – the challenge was to up-rate the machines to double this capacity whilst utilising the same concrete structure already situated within the confines of the site.
After significant discussions with the client it was decided to modify the screw pumps to an innovative 3 bladed design and up-rate the current drive systems with WEG 45KW motors and uprated Siemens gearboxes to double the capacity to 1200l/s. This complicated design change was developed in house at Landustrie and meant that the total width increase of the screw pump bodies only had to increase by 300mm, this was followed up by the use of finite element analysis (FEA) to ensure the design met with the client’s Whole Lifetime Costs requirements.
ECS has designed out the requirement for the historical hand screeding process by manufacturing the units with cast-in steel liners. The innovative design of these liners allows for speedier installation, minimal manual intervention by civil engineers and a strong, durable and efficient lining to the trough that will last for years to come.
Jamie Wesley, Commercial Manager for the Water Control Division at ECS comments, “The new screw pumps have been designed by Landustrie, specifically for this project and they will deliver significant savings in both energy and maintenance costs for the client together with increased flood protection for the Bangor area. Our engineers will be providing the technical expertise to ensure the screw pumps are properly installed and commissioned to give years of trouble-free service”
