DAB EVOSTA2 1 1/139 SAN R 1/2'' SERIES BRASS BODY RE-CIRCULATION PUMPS - WITH FREQUENCY CONVERTER
General Information
Evosta2 11/139 SAN series has an extremely compact structure. The motor outer body is plastic, the pump body is brass. In hot water installations with boilers, they circulate hot water throughout the building, allowing residents to use hot water from their taps instantly without waiting. Domestic hot water re-circulation There are many differences between pumps and boiler or combi heating pumps. Since fresh water is continuously pumped into recirculation pumps, the risk of calcification is very high. In order to prevent the pump from getting blocked and burning due to calcification, the body is made of well-processed smooth brass material to prevent lime accumulation. In addition, since the pump is manufactured with a wet rotor, the rotor -Lime accumulation between the stator is minimized. They are very fast pumps. They prevent unnecessary water consumption, time loss and energy loss.
ATTENTION: Evosta2 11/139 and Evosta2 11/85 recirculation pumps are exactly the same in terms of motor power and performance. In the 11/139 model, there are 2 external thread adapters connected to the pump inlet and outlet. One of the external thread adapters has an internal check valve. In this way, re -Reverse water circulation in the circulation line is prevented.
