Series Characteristics
- Electric Circulator pumps with in-line suction and discharge ports, designed for direct installation onto piping, with threaded connections.
- The design is based on the spherical rotor/stator technology. This implies that:
- The only moving part is the spherical rotor. Impeller block group that turns on a hard ceramic ball bearing.
- Shaft seals or conventional bearing bushings with a shaft have been eliminated for a single self realigning spherical bearing.
· Blockage free rotor: the special motor principle does not require a manual unblocking device thanks to the small touching surface of the bearing on the ball. The starting torque required is minimal.
· Automatic regulation by setting a single selector switch place on the motor housing. This ensures considerable energy savings and a low noise level during operation.
Advantages
- Energy saving.
- Blockage free.
- Minimal maintenance
