UPA 15-90
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. The integrated flow switch starts or stops the pump when a tapping point is turned on or off.
• 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 is 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 15-90 pumps have a 2-pole, asynchronous, squirrel-cage motor. The motor has a built-in impedance protection and is short-circuit-proof. No external motor protection is required.
• The integrated flow switch starts or stops the pump when a tapping point is turned on or off
• The flow switch consists of an arm with a magnet (1), that moves in a chamber (2)
• The chamber is separated from the pumped liquid and the terminal box
• The magnetic field activates a magnetic contact (3).
