GRUNDFOS CONLIFT 1

Product detailed description

Compact pump GRUNDFOS CONLIFT 1

CONLIFT is a professional range of condensate pumps designed for a long service life and quiet operation. The product is an excellent choice for situations where condensate is generated at a point below the building's normal drainage level.

Frequently asked questions

• How to choose the right performance (head) of a circulation pump? The head (expressed in metres) must cover the pressure losses of your specific heating circuit - these depend on the pipe length, the number of radiators/circuits and the resistance of the fittings. For a typical family house, a pump with a head of up to 6 m is usually sufficient; for larger or multi-zone systems, a higher head is chosen (8 m or more) - if in doubt, consult a heating engineer who can precisely calculate the flow and head for you.
• What does the connection size (e.g. 6/4") on a pump mean? This is the threaded connection of the pump to the pipe - it must match the pipe diameter in your system, or a reducer must be used. This value must not be confused with the DN of the suction/discharge port, which indicates the bore of the pump's port itself.
• What is the difference between a single-speed and a multi-speed/electronic pump? A multi-speed pump allows you to manually switch between several fixed power levels according to the needs of the system, while an electronic (controlled) pump smoothly adjusts its output automatically according to current demand - this means lower electricity consumption and generally quieter operation.
• Why is the pump noisy, and can this be solved? Increased noise may be related to an incorrectly set (too high) power level relative to the needs of the system, the presence of air in the system, or the fact that the chosen model is not primarily designed for quiet operation in residential spaces. If the noise bothers you, we recommend trying a lower power level, thoroughly bleeding the system, or considering an electronically controlled model, which is generally quieter, especially at partial output.
• Must installation be carried out by a professional? A handy DIY enthusiast can manage the actual installation of the pump into already prepared piping (with the correct threading); however, we recommend having the electrical connection to the power supply and commissioning, together with balancing the entire system, checked by a heating technician.
