Circulation pump DAB A 80/180 XM

The DAB A 80/180 XM circulation pump is the most powerful model in the DAB A series, designed for heating, air-conditioning, and heat supply systems requiring high flow rates and stable operation under significant hydraulic loads. This pump is ideal for commercial and industrial facilities handling large volumes of heat-transfer fluid.

The maximum flow rate reaches 8.7 m³/h, and the head is up to 9 meters, making it highly effective for central heating networks, large-scale cooling circuits, ventilation systems, and extensive HVAC installations.

Construction and materials

▪️ Hydraulic body made of high-strength cast iron, built for long-term operation under heavy loads.
▪️ Impeller made of technopolymer, resistant to chemical impurities and abrasive wear.
▪️ Stainless steel rotor with wet-rotor technology — quiet, stable, and durable.
▪️ EPDM sealing, optimized for high-temperature applications.
▪️ Motor bearings lubricated by the heat-transfer fluid — maintenance-free.

Operating characteristics

▪️ Pumped liquid: clean water or glycol mixtures up to 30%.
▪️ Fluid temperature range: –10 … +110°C.
