𝗕𝗲𝘀𝘁𝘀𝗲𝗹𝗹𝗲𝗿
Bronze circulator with nine programs for drinking water circulation and recirculation. For 130 mm port to port.
𝗨𝘀𝗲 𝗶𝘁 𝗳𝗼𝗿: secondary hot water returns in houses and flats where the demand swings through the day · cylinder loops on vented and unvented cylinders · hot water return loops in hotels, guest houses, care homes and student halls · commercial kitchens, sports clubs and changing rooms · calorifier and water heater circuits in plant rooms · cold potable water circulation from a storage tank · any drinking water loop where a pump that matches its output to demand will cut the running cost against a fixed speed pump
𝗥𝗶𝗴𝗵𝘁 𝗳𝗼𝗿 𝘆𝗼𝘂 𝗶𝗳
• The water is drinkable, so the body needs to be bronze
• You want the pump to match its output to demand instead of running flat out
• Your pipework measures 130 mm between the union centres

𝗡𝗶𝗻𝗲 𝗽𝗿𝗼𝗴𝗿𝗮𝗺𝘀, 𝗮𝗹𝗹 𝘀𝗲𝘁 𝘄𝗶𝘁𝗵 𝗼𝗻𝗲 𝗯𝘂𝘁𝘁𝗼𝗻
𝗔𝗨𝗧𝗢. The pump works out the right operating range for your system on its own.
𝗖𝗼𝗻𝘀𝘁𝗮𝗻𝘁 𝗽𝗿𝗲𝘀𝘀𝘂𝗿𝗲, 𝗖𝗣𝟭 𝗮𝗻𝗱 𝗖𝗣𝟮. Holds the same pressure whatever the flow rate.
𝗣𝗿𝗼𝗽𝗼𝗿𝘁𝗶𝗼𝗻𝗮𝗹 𝗽𝗿𝗲𝘀𝘀𝘂𝗿𝗲, 𝗣𝗣𝟭 𝗮𝗻𝗱 𝗣𝗣𝟮. Adjusts in proportion to the flow, which saves the most energy.
𝗧𝗵𝗿𝗲𝗲 𝗳𝗶𝘅𝗲𝗱 𝘀𝗽𝗲𝗲𝗱𝘀. The full power range, minimum to maximum.
𝗡𝗶𝗴𝗵𝘁 𝗺𝗼𝗱𝗲. Drops to 5 W in the quiet hours without losing the system.
𝗚𝗼𝗼𝗱 𝘁𝗼 𝗸𝗻𝗼𝘄
Bronze body, so it suits drinking water. Down to 5 W when demand is low, against 72 W for a fixed speed bronze pump running constantly. Electrical and thermal protection is built in. Insulation jacket in the box at no charge.
𝗕𝟭, 𝗕𝟯 𝗼𝗿 𝗕𝟰? All three are bronze, for drinking water. B1 has three fixed speeds and is the cheapest. B3 and B4 have nine programs and adjust their own output, using far less power.
𝗕𝟯 𝗼𝗿 𝗕𝟰? Same pump inside, nine programs, same job. Two differences. The B3 is the standard body at 130 mm port to port. The B4 is the compact body, built to fit where a standard looking pump will not go, at 180 mm port to port. Measure between the centres of your two unions and look at the space around the pump, and the choice makes itself.
