Heating systems
Common uses:
• Ground-source heat pumps
• Radiant floor heating
• Hydronic and fan-coil heating
• Solar heating
• Heat recovery/heat pumps.
Pump types with cast iron housing are generally used
for these applications, considered to be closed systems
pumping water or water/glycol mixtures. However,
when water conditions exist that are not compatible
with cast iron, we recommend the use of bronze or
stainless steel.
Building on success
Due to the popularity of the UPS15-58 SuperBrute, we designed four
new models to expand the 3-speed circulator range. For most hydronic
heating applications, the UPS15-58 is the only circulator you will ever
need. But, since some situations require unique demands, the UPS26-
99, UPS43-44, UPS15-35 and UPS15-55 were designed to complete the
SuperBrute range. All the pumps contain the same features that made
the original SuperBrute such a sought-after alternative. Flexibility, ease
of installation, and reduced inventory are the benefits that make the
SuperBrute team the new standard in circulators.
General Overview:
A wet rotor circulator pump is designed to be smaller and more efficient than standard pumps. Standard pumps use a mechanical seal to connect the motor to the “water moving side.” A wet rotor circulator pump does not have this type of connection (coupling) since all the rotating parts are totally immersed in water by means of a stainless steel barrier (canister) that isolates these rotating parts from the motor. The water keeps the circulator lubricated and running cool. Since there is no
mechanical seal, there are fewer moving parts that might fail and cause the pump to leak. Grundfos® Pumps has developed several wet rotor circulator pump models to meet the needs of domestic hot water recirculation systems. |

• 5 models replace 63 competitor pumps on the UP(S) S = 3-speed
• SuperBrutes offer a 3-speed switch for extreme flexibility
