DAB.EVOPLUS SMALL - electronic circulation pumps for small heating/air conditioning

The DAB.EVOPLUS SMALL range includes electronically controlled circulation pumps designed for small heating and air conditioning systems. These pumps use a synchronous motor with permanent magnets and frequency control to adapt to hydraulic system changes, ensuring efficient operation while meeting European energy regulations. They are suitable for systems requiring low to moderate flow rates and head pressures, such as compact residential HVAC units, underfloor heating, and small commercial ventilation systems.

Available in both threaded and flanged connection options, these pumps support a wide range of installation requirements. The liquid temperature range accommodates both heating and cooling applications, and the pumps are compatible with glycol-based mixtures up to 30% concentration.

How to choose

• Assess the required flow rate (2 to 12 m³/h) and head pressure (up to 11 m) to match the system’s hydraulic needs.
• Select the appropriate connection type: threaded (1 1/2” or 2”) or flanged (DN 32 or DN 40) based on the system piping configuration and pressure class (PN 6, PN 10, or PN 16).
• Ensure the pumped medium is clean, chemically neutral, and has properties similar to water or a glycol mixture with no more than 30% concentration.
