The Grundfos CONLIFT is a professional range of condensate pumps designed for long-life and silent operation. The solution is an excellent choice for applications where the condensate produced falls to below the dwelling’s normal discharge height.


The robust pump and a built-in reservoir of 2.6 litres make the CONLIFT a reliable and efficient addition to any system. The range contains two variants.


CONLIFT L - a basic version (Hmax=4.5m, Qmax.=342 l/h). An extra level switch with a potential free contact for shutting-off of condensate source (e.g. boiler) or external alarm device.


CONLIFT - an advanced (Hmax=5.4m, Qmax=420 l/h) with an extra level switch for internal acoustic alarm and additional start of pump for more safety. Both versions are delivered with cable and a plug, an integrated non-return valve, a discharge hose and adapters.




CONLIFT removes condensate from boilers, chimneys, as well as air-conditioning systems, cooling and refrigerator systems, when it is collected below sewer level, or cannot be led away via natural gravitation to the sewer or the building's drainage system. Condensates from boilers are aggressive.


CONLIFT can pump condensate with a pH value > 2.7 from boilers with a useful output of less than 200 kW.
