KGN Pillinger has supplied and installed this new booster set for the County Hall Hotel in London.

KGN Pillinger has designed, made and installed the new 4-pump booster set to replace a 15-year-old set at the County Hall Hotel in London of Marriott Hotels. The hotel is next to the London Eye. There was a problem with the phase loop controller, an expensive item to replace, and the bearings of one pump needed attention. An inline PRV also required regular servicing.

Adam Faulkner, Marriott’s assistant chief engineer says, ‘We received three quotations. Although KGN was not the cheapest, we were impressed by the thought and time that was put into the quotation and the methodology behind it.’ The KGN quote include the core product and regular servicing of equipment.

KGN engineers removed the old set and installed the new one — including pipework modifications and electrical connections to existing supplies.

The new set delivers a flow rate of 48 l/s at 7.5 bar. The pumps operate on a duty-assist-assist-assist combination, producing 12 l/s per pump. Each 15 kW motor has been fitted with a Hydrovar inverter.

Alan Faulkner remarks that the pumps run less often and that the variable-speed drives makes them noticeably quieter and slows them down when demand is low.
