Grundfos Pumps - Cast Iron
Grundfos pumps set the industry standard for circulator pumps in radiant heating and hydronic heating applications. Models such as UPS15-58FC and UPS26-99FC are extremely versatile and are suitable for a large number of applications where flexibility and reliability is needed.
Cast Iron Grundfos Pumps are available in standard UP models and 3-speed UPS models.
For models with rotated flange, see SKU#'s that include "R", for example, UP15-42FR.
For models with built-in check valve, see SKU#'s with "C", for example UPS15-58FC.
A pair of O-rings (gaskets) is included with every flanged circulator. Pump flanges are sold separately.
Grundfos Cast Iron Circulators are common for radiant, hydronic, baseboards, radiators, fan coils heating and other closed loop hot water heating and snow melting applications.
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.
