Recirculating pump COMFORT 15-14 BDT PM Grundfos

The high-efficiency Grundfos COMFORT BDT PM and BXDT PM pumps are designed for the recirculation of domestic hot water in single-family houses and homes, ensuring instant hot water at all taps.

The pumps have a corrosion resistant casing suitable for potable water and are powered by a high efficiency single phase ECM with permanent magnet rotor. The integrated digital timer has been developed for the recirculation of domestic hot water in systems with hot water tanks or plate heat exchangers for hot water production.

The timer allows you to customize the periods of operation of the pump, ensuring optimal comfort and reducing energy costs. In addition, the pump can be configured for 100% continuous operation for pump commissioning or 24-hour instant hot water. COMFORT BXDT PM has a built-in isolation valve and check valve (fitting). This ensures that maintenance can be performed without draining the system. The check valve also prevents reverse flow during operation.
