The pump set prevents the temperature in the boiler from falling under the dew point, thus reducing contamination of the boiler.The pump set is mounted between the buffer tank and the boiler.The actuator PM2 is is controlled by an external controller.The actuator opens the 3-way valve only when the boiler circuit has reached the opening temperature set.Then the pump can charge the tank.
The pump sets DN 40 and DN 50 with pumps DN 32 are delivered with reducer flanges.The pump sets DN 25 and DN 32 are delivered with insulations.
