The Grundfos UPS2 is the ideal replacement for UPS 15-50 and 15-60s in domestic heating systems.

The UPS2 comes complete with modern motor technology and electronic control which enables it to meet current EuP/ErP standards. The UPS2 comes as a complete pump or as a pump head only.


The Grundfos UPS circulator pumps are designed for the following:

  • Domestic heating systems


Watch this short video to see how easy it is to replace a boiler pump head with a Grundfos UPS2.

  • Air-conditioning & cooling systems
  • 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.
  • The control box of the UPS2 can be mounted on the left, right or on the top.
  • 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.
  • 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.
  • The UPS2 is almost identical in overall dimensions to the UPS15-50/UPS15-60 models.
  • The UPS2 is fitted with a screw which allows manual venting to remove air from the heating system.
  • 5 year warranty
