Circulation pump Wilo-Star-Z NOVA A
Circulation pump Wilo-Star-Z NOVA A
This circulation pump is designed exclusively for domestic hot water and is ideal for single-family buildings. The glandless version of the Wilo-Star-Z NOVA A is mounted directly on the pipeline, which allows efficient circulation of hot water in heating systems. The unit is equipped with a synchronous motor resistant to current at blockage, which is characterized by high starting torque
The pump body is made of brass (CW617N) and the impeller is made of noryl, while the shaft is made of ceramic material. The pump features very low power consumption - from 3 to 5 watts. As standard, the unit is equipped with a thermal insulation cover and has a Rp ½ body thread. It also comes with a ball shut-off valve and a check valve with G1 thread
