Hyundai Hot Water Booster Pump 123W

This small stainless steel circulator pump is designed for boosting hot & cold water pressure in domestic properties. Boost hot & cold water circulation in domestic applications. Suitable for heating, ventilating and air conditioning HVAC circulation, pressure boosting of hot water in homes powered by solar energy, industrial auxiliary equipment, cold and hot water circulation. Designed for open vented systems, it can also be installed directly on the incoming water mains supply to feed a combination boiler subject to local authority approval. This integral flow switch design provides additional pressure to outlets where the required flow rate is up to 0.3 l/s. Operation is by three-position switch, OFF, MANUAL and AUTO. In the AUTO mode the pump starts and stops using the integral flow switch (activated by a gravity flow of 2 l/min). The gravity flow at all fittings should be checked to ensure that the pump will operate when the outlet fitting is opened. When the MANUAL mode is selected the pump will run continuously. Suitable for pumping clean, thin, non-aggressive liquids not containing solid particles or fibres (rain water, potable water, fresh water) 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. FEATURES • Boost water pressure in domestic applications • Flow switch for AUTO operation • Adds 0.5 - 0.75 bar of pressure to the inlet pressure at the pump • Quiet design • 1.5 metre flying lead for connection to a 3A fused switched spur • Suitable for pumping clean, thin, non-aggressive liquids not containing solid particles or fibres • 2 Year Hyundai Warranty To avoid cavitation noise and risk of damage to the pump bearings, a minimum inlet pressure of 1.5 m head (0.15 bar) is required at the pump during operation.
