Grundfos UP series circulators:
Designed for basic zoning applications, Grundfos UP series circulator pumps are available in a wide range of models to match the needs of any heating system. These models are a straightforward solution for most common recirculation applications where heat load, pressure drop and flow parameters are known.

Grundfos UPS series circulators:
Grundfos UPS series cast iron circulator pumps are 3-speed models, equipped with a Hi/Med/Low switch which allows to easily adjust the circulator output, thus matching the head and flow requirements of a system.
