Landustrie Archimedes screw pumps double capacity of water storage in Bangor, Northern Ireland

Posted on 2 February 2015

dws-landustrie-screw-pumps-bangor-ireland-770pxESC Engineering Services has delivered two Landustrie Archimedes screw pumps to Northern Ireland Water for Luke's Point pumping station in Bangor City, near Belfast.

Northern Ireland Water is modifying the pumping station and adding an underground 3,250 m3 storm water capacity. The two new screw pumps will double the pumping capacity to 1,200 l/s. The screw pumps were specially designed by Dutch leading manufacturer Landustrie.

The 3 million UK pound upgrading project will reduce the flooding in the city, and also reduce the discharge of untreated storm water in the Belfast Lough, thus improving Northern Ireland's coastal water quality.

Within the original footprint
Jamie Wesley, commercial manager of ESC Engineering Services comments, "Increasing the capacity of the pumping station while remaining within the original footprint required some innovative engineering – the key aspect was to increase the diameter of the screws – which required the removal of the original concrete dividing wall. This provided sufficient space to install the pair of larger screws, housed in steel troughs to provide optimum pumping efficiency."

Lower energy and maintenance costs
Jamie Wesley continues, "a new screw pump installation has been designed by Landustrie, specifically for this project and it will deliver significant savings in both energy costs and maintenance costs for the client. Capable of pumping 1,200 litres per second each, the increased capacity compared to the original will go a long way to improving the ability of the station to deal with periods of increased rainfall."

The new installation includes the Landustrie eco-friendly stainless steel, lower bearings which are sealed for life and require no annual maintenance.

The design of the bearing allows for 3-dimensional self-alignment, which absorbs the expansion and contraction of the screw in changing temperatures.

Legacy installations such as Luke’s Point used poly v-belts to transfer drive from the motor to the gearbox, in part to lessen the shock loading on start up.

With the introduction of variable speed drives (VSD) and improved drive couplings it is now possible to use direct power transmission which offers around 5% energy savings in addition to those provided by the VSD.
