This pump replaces the UPS 15-50 (130) and UPS 15-60 (130) directly. No alteration to pipework or fittings is necessary. The new Grundfos UPS2 15-50/60 (130) is a high-efficiency circulator pump with permanent-magnet motor (ECM technology) and continuously variable speed control for circulation of clean heating water. The UPS2 is the ideal replacement for UPS 15-50 and 15-60s in domestic heating systems, it comes complete with modern motor technology and electronic control which enables it to exceed new EuP/ErP standards. It is also available as a complete pump or as a pump head only. Features and benefits Three Pumps in One - The UPS2 can be set to meet the requirements of a UPS15 model designed for either 4m, 5m or 6m performance. Control Box - The control box of the UPS2 can be mounted on the left, right or on the top. Cable Gland - The cable gland of the UPS2 is the same design as that used on both the UPS15-50 and UPS15-60 circulators. This minimises time taken on changeover. Pump Head - Where the existing pump base is in good condition a pump head option can be chosen in order to minimise installation time by replacing the pump head only. Dimensions - The UPS2 is almost identical in overall dimensions to the UPS15-50/UPS15-60 models. Vent screw - The UPS2 is fitted with a screw which allows manual venting to remove air from the heating system.
