This circulator is suitable only for drinking water.

Can be used for domestic hot water circulation systems in the industry and building services.

Glandless circulator with screwed 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 with thermal winding contacts in conjunction 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
Fault signal light
Contact for collective fault signal
Direction of rotation signal lamp
Mains connection 3~, 230 V with optional switching plug
Pump housing in red brass or grey cast iron (stainless steel depending on type)
PN 6/PN 10 combination flange (for DN 40 to DN 65)
Thermal insulation shells
Additional functions by retrofittable Protect Module C:
- SSM fault signal as potential-free NC contact
- SBM run signal as potential-free NO contact
- "Overriding Off" control input via external potential-free contact (NC contact)
- Blocking detection
- Full motor protection with tripping unit
- Fault acknowledgement
Dual pump management (two single pumps installed in parallel): Main/standby operation (automatic fault-actuated switchover/time-dependent pump cycling)
