Delta circulation pumps are used for pumping both cold and hot liquids in heating systems, industrial washes, irrigation and pressure rise. Impeller housings and impellers are made of cast iron, impellers are alternatively available in polymer.
From connection 50 there are pumps with a maximum working pressure of 16 bar and a maximum temperature of 140 °C, which means that they can also be used for district heating.
Parts of the Delta series can also be used to replace many of the older 3x400V pumps with a short construction length. The short construction length is available in DN40 to DN80 and has a double-drilled flange for both PN6 and PN10. This means that the pump fits directly without rebuilding.
