UPA 120
UPA booster pumps increase the pressure of domestic water to make the required pressure available at showers, taps and other tapping points.
UPA booster pumps are designed for pressure boosting of domestic water supplied from an external source in residential homes. UPA booster pumps are used in open systems and can also be connected directly to the water main
• Flexibility: Suitable for installation in existing systems.
• Comfort: : Low-noise operation.
• User friendliness: Plug and play.
• Reliability: : Proven Grundfos quality.
• Energy-efficiency: : High-efficiency PM technology.
• Corrosion-resistant: Cataphoresis-coated pump housing.
UPA circulator pumps for pressure boosting are of the canned-rotor type, that pump and motor form an integral unit without shaft seal. Only two gaskets are required for sealing. The bearings are lubricated by the pumped liquid.
UPA 120 pumps have a 2-pole, asynchronous, squirrel-cage motor. The motor incorporates thermal overload protection, so no external motor protection is required.
• An external flow switch is available as an accessory.
• The external flow switch is placed after the outlet of the pump and starts or stops the pump when a tapping point is turned on or off.
