Grundfos UPA15-90N Hot Water Circulator Pump

The Grundfos UPA15-90N is a domestic home booster pump designed for boosting pressure on potable water and domestic hot water.  The pump provides additional pressure to showers, taps and similar outlet points. The pump incorporates a flow switch which starts or stops the pump when a tap is turned on or off and is supplied with a 1.5 metre flying lead. This pump has 160mm port to port dimensions.

The Grundfos UPA 15-90 N is a small stainless steel circulator pump, designed for water pressure boosting in domestic properties to provide additional pressure to hot and cold water taps and similar outlet points. The UPA 15-90 N is mainly for use in open vented systems, but may also be installed directly on the incoming water mains supply to feed a combination boiler, provided approval has been obtained from the local Water Company. The pump incorporates a flow switch which starts and stops the pump according to flow when a tap is opened or closed. The pump is supplied with a 1.5 metre flying lead for connection to a 3A fused switched spur.

Applications & Operation

The UPA 15-90 N is a circulator booster pump with integral flow switch designed for pressure boosting of hot or cold water supplies in domestic properties. The pump provides additional pressure to taps and similar outlet points, where the required flow rate is up to 0.3 l/s. The operation of the pump can be selected by means of a three position switch, OFF, MANUAL and AUTO. In the AUTO position the pump is started and stopped by the integral flow switch. The flow switch is operated by a gravity flow of 2 l/min. The gravity flow at all fittings which require boosting should be checked to ensure that the pump will operate when the outlet fitting is opened. When the MANUAL position is selected the pump will run continuously. The pump should not be operated for long periods without flow through the pump. Minimal maintenance of the pump is required. Periodically the flow switch may need cleaning depending on operating conditions.
