Can be used for hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits.
Maintenance-free glandless circulation pump with threaded or flange connection, preselectable speed stages for power adjustment.
Equipment and function
- Manual power adjustment with 3 speed stages
- Pumps with 1~ motor:
- P2 up to 90 W: Internal protection against unacceptably high winding temperatures
- P2 = 180 W: Full motor protection by thermal winding contacts in combination with tripping unit
- Pumps with 3~ motor:
- P2 up to 90 W: Internal protection against unacceptably high winding temperatures
- P2 ≥ 180 W: Full motor protection with integrated trip electronics
- Mains connection 3~230 V with optional switching plug
- Cataphoretic-coated pump housing for optimal corrosion protection
- Combination flange PN 6/PN 10 (with DN 40 to DN 65)
- Thermal insulation shells for heating applications
- Additional functions with retrofittable Protect Module C:
- SSM fault signal as potential-free normally closed contact
- SBM run signal as potential-free normally open contact
- "Overriding Off" control input by external potential-free contact (normally closed contact)
- Blockage detection
- Full motor protection with built-in tripping
- Fault acknowledgement
- Dual pump management (two single pumps installed in parallel): Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling)
