$ 294.84The Grundfos circulator pumps, Series UP, are specifically designed for heating systems. The pumps are also suitable for circulation of hot domestic water and for circulation of liquid in cooling and air-conditioning systems.
Heating systems - Common uses:
Ground-source heat pumps
Radiant floor heating
Hydronic and fan-coil heating
Heat recovery/heat pumps
Pump types with cast iron pump housing are generally used for these applications, considered to be closed systems, for pumping water or water/glycol mixtures. However, when water conditions are not compatible with cast iron, we recommend the use of bronze or stainless steel.
Optional variable-speed and mixing-reset controls are available to customize heat output vs heat demand for increased comfort.
Domestic hot-water systems - Common uses:
Solar water heating
Domestic hot-water heating.
Pump types with bronze, brass or stainless steel pump housing are used for these applications, considered to be open systems, for pumping potable water.
Optional timer and thermostat controls are available to limit pump operation to periods when hot water is required and to save energy.
Cooling systems - Common uses:
Pump types UP(S) 25, 26, 43, 50 and pump housings compatible with the pumped liquids are recommended for chilled water due to their motor construction, which is suitable for 32 ?F (0 ?C) water.
Construction - Characterized by:
Ceramic shaft and radial bearings
Carbon thrust bearing
Stainless steel rotor can and bearing plate
Impeller of corrosion-resistant material
Pump housing of cast iron, bronze or stainless steel.
