UPA 15-160
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. UPA 15-160 consumes up to 87 % less electrical power than a conventional constant-speed booster.
• 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 15-160 is energy-optimised due to improved hydraulics and an electronically commutated motor (ECM) with permanent-magnet rotor and frequency converter.
The pump controller is incorporated in the control box, which is fitted to the stator housing.
• The external flow switch is placed after the outlet of the pump.
• The 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).
• Fresh water
• Potable water without chemical additives
• Chlorinated potable water
• UPA booster pumps are not suitable for the transfer of flammable liquids such as diesel oil and petrol.
