THE QUIET REVOLUTION
Grundfos® VersaFlo® UP(S) Wet Rotor Circulators
Grundfos® Pumps is the only manufacturer of large, wet-rotor circulators in the U.S. commercial market with a proven track record of more than 25 years experience. Our VersaFlo® UP(S) wet rotor circulators are whisper-quiet and maintenance-free. They feature an integrated pump and motor design. Fewer parts means greater ease of installation and durability.
Fans are often a source of noise and vibrations that can resonate throughout a building via pipe work. Wet rotor design eliminates the need for a fan to cool the motor: water being pumped surrounds the rotor, cooling and lubricating the shaft and bearings. No noise. Just quiet.
The Grundfos® VersaFlo® UP(S) wet rotor circulators are virtually maintenance-free and offer many advantages over three-piece, dry rotor pumps.
> No seals - eliminates hot water leakage
> No oil - pumped water is the lubricant
> No couplers - ensures no maintenance required
INCREASED OPERATING EFFICIENCY
The VersaFlo® UP(S) uses dynamically balanced rotors and laser-welded, stainless steel, curved blade impellers. Stainless steel impellers provide a higher pump efficiency than cast-bronze or cast-iron impellers.
ENERGY AND COST SAVINGS
The speed switch on the VersaFlo® UPS motor allows you to adjust the pump speed to meet the needs of your system, thereby reducing energy consumption and saving you money.
VersaFlo® UP(S) pumps are available in varying sizes and material construction ideal for commercial buildings and large residences.
> Cast iron for closed systems (heating and air conditioning)
> Bronze for open systems (domestic hot water)
> Heating systems for apartments, colleges, and hospitals
> Hot water recirculation for apartments and hotels
> Snow melt, and hot water recirculation for large residential and light commercial
> Radiant heating for residential and com-mercial structures
Most VersaFlo® UP(S) pumps can replace other manufacturers’ three-piece dry runners without piping modifications − and occupy less space. For more information about VersaFlo® UP(S) pumps, contact your Grundfos® representative or visit www.versaflo.com.
BUILT TO LAST
The stainless steel impellers, rotor shaft, bearing plate, and rotor cladding on VersaFlo® UP(S) pumps are corrosion-resistant and built to last.
You can ensure that the electrical connections and rotation of your pump are correct by checking the indicator lights on the terminal box.
