A Booster Pump Set “Pent-A-Boost” shall be installed – model BTAF3-10S - as manufactured and distributed by Arrow Valves Ltd - Tel 01442 823123 www.arrowvalves.co.uk. The unit shall have an 24 litre cistern, with a lid and screened DN40 overflow complying with G16.13 of the Water Regulations. The pumps shall be centrifugal with stainless steel impellors and housings. The pump speeds shall be varied by an integral inverter to provide a constant pressure. The pump controller shall feature alternate pump use. The duty at 100% output shall be 4.0 bar @ 0.9 lt/s and be controlled by a pressure transducer, which is damped with a 24 litre pressure vessel. The cistern level shall be controlled automatically by a servo solenoid valve operated via stainless steel conductive electrodes and controller. A low-level pump cut-out shall be controlled by electrodes in the cistern, which shall automatically reset once the cistern is sufficiently full. The cistern shall feature a high-level alarm linked to a volt free BMS relay – model BTBMS2. The unit shall feature a stainless steel base plate and be acoustically attenuated by anti-vibration feet and stainless steel braided flexible hoses. A 28 mm supply is required, which must maintain a dynamic pressure of 1.0 bar.
