Aspen Endurance boiler pump / condensing pump | Endurance

The Aspen Endurance, the most powerful boiler pump in its class

The Aspen Endurance is built tough to maximise reliability in boiler applications. The design allows for short irregular temperature fluctuations of up to 85°C. In addition to the very high flow rate of 550 l/h, the pump is characterised by a very low running noise of 44 dB(A) and a very good pH value of >2.2. For applications with upstream neutralisation, condensates with pH <2.2 can be pumped.
