Spare Grundfos pump heads are available to fit the entire model range of circulator pumps. These circulator pumps are most commonly used in cooling and heating systems. All of the Grundfos circulator pumps incorporate the patented AUTOadapt feature that controls the pump's performance. This patented technology automatically adjusts the differential pressure to keep it in line with the flow, ensuring that the pump operates with optimal performance and efficiency at all times.
The motor design, which includes a permanent magnet, is highly energy-efficient and is able to reduce power consumption by 50 per cent or more compared with the circulator pumps of similar power consumption on offer from rival brands.
The heads fit 240 V pump models UPC/D 40-60, 40-120, 50-120, 55-120, UMC/D 50-60 and 65-60. The manufacturers recommend that the pump terminal boxes are changed along with the pump head in order to maximise the pump’s operational life span.
The UPC/D terminal box heads are also compatible with the UPS/D 30-60/2, UPS/D 40-30/4, UPS/D 50-30/4, UPS/D 32-120/2, UPS/D 40-60/4, UPS/D 50-60/2, UPS/D 32-120/2, UPS/D 40-60/4 and UPS/D 50-60/2 circulator pump head models. The UMC/D 65-60 replacement terminal box is compatible with pump head models UPS/D 50-60/4 and UPS/D 65-60/4.
