Packaged pump solution helps keep railway project on track

Armstrong Pumps, package pumpset
Prefabricated pump solutions from Armstrong have been installed as part of the refurbishment of London Underground’s Neasden Depot.

Offsite manufacture of Armstrong 8000 Series packaged pump solutions played a key role in helping to meet extremely tight project timescales for the refurbishment of London Underground’s Neasden Depot. This is the largest depot on the London Underground network and the main depot for the Metropolitan Line. The refurbishment will create facilities suitable for a new fleet of air-conditioned trains.

The Armstrong package included a motive-power distribution board requiring a single point of mains supply for each module. Control was supplied via an integrated Armstrong IPS multi-zone controller. This controller is mounted on the module and wired in the factory; it maximises energy savings by modulating pump speed to suit demand.

On the appropriate date in the build schedule, the fully assembled and tested modules were delivered to site for assembling into the system pipework.

8000 Series pump solutions are predesigned by Armstrong, so costs typically incurred by the contractor at system design stage are reduced. The package also provides the best integration of pumps with efficient variable-speed pump-control technology to deliver exceptional performance throughout its life.

Dominic Cutts, of Armstrong Systems, says, ‘There is growing awareness that where the system is integrated with control and automation by the equipment manufacturer, there are opportunities for energy efficiency that cannot generally be achieved when using traditional on-site assembly approaches.’
