- Direction of rotation signal lamp for displaying the correct sense of rotation (only with 3~)
- Manual power adjustment with 3 speed stages
- Pump housing with cataphoretic coating (KTL) protects against corrosion due to condensation formation
Construction:
Glandless circulator with screwed connection or flange connection.
Materials:
- Pump housing: Grey cast iron
- Impeller: Plastic
- Shaft: Stainless steel
- Bearing: Carbon, metal impregnated
Application:
Hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits.
Operating Modes:
- Speed-stage switching
Manual Functions:
- Setting the speed stages: 3 speed stages (2 speed stages for 1~ pumps with P2 ≥ 350 W)
Automatic Functions:
- Internal protection against non-approved high winding temperatures (only for pumps for which P2 ≤180 W)
Signal and Display Functions:
- Thermal winding contact (WSK, potential-free NC contact) only for pumps for which P2 ≥180 W) for full motor protection in all speed levels with optional tripping unit SK 602N/SK 622N
- Direction of rotation control light (only for 3~pumps)
- Display of selected speed stage
Automatic Functions:
- Internal protection against non-approved high winding temperatures (only for pumps for which P2 ≤180 W)
Dual Pump Management (twin-head pump or 2 x single pumps):
- Main/standby operation or parallel operation (for automatic fault-actuated switchover/time-dependent pump cycling, a corresponding switchgear must be provided on-site)
Equipment:
- For flange-end pumps: Flange versions
- Standard version for DN 40 to DN 65 pumps: PN 6/10 combination flange (PN 16 flange according to EN 1092-2) for PN 6 and PN 16 counter flanges
- Standard version for DN 80/DN 100 pumps: PN 6 flange (designed for PN 16 according to EN 1092-2) for PN 6 counter flange
- Cable inlet possible from both sides (only for 1~pumps and 3~pumps with P2≥180 W)
- Thermal insulation as standard for heating applications
