With a 6 metre head and a G1½\" threaded connection on the standard 180mm port to port body, it's the natural direct replacement for older fixed speed circulators in most UK three and four bedroom homes, and it's equally at home in ground source heat pump and secondary mixing loop applications. A permanent magnet motor with a built in frequency converter automatically matches flow and head to real system demand, so you get quieter running, lower running costs and a genuinely low maintenance canned rotor design with no shaft seal to fail. Whether you're a home owner replacing a tired circulator or an installer sourcing a reliable, easy to set pump for a client's boiler upgrade, the MAGNA1 25-60 delivers dependable, energy efficient circulation.\u003c\/p\u003e\n\u003ch2 style=\"font-family: Arial, Helvetica, sans-serif;
