Wilo - TOP-S 25/7 REPLACEMENT Head - 230V - Single Phase

• Direction of rotation signal lamp for displaying the correct sense of rotation (only with 3~)
• Manual power adjustment with 3 speed stages
• Pump volute casing with cataphoretic coating (KTL) protects against corrosion due to condensation formation

Construction:

Glandless circulation pump with screwed connection or flange connection.

Application

Hot-water heating systems of all kinds, industrial circulation systems, air-conditioning systems and closed cooling circuits

Equipment/function

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 overload 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

Dual pump management (twin-head pump or 2 x single pumps)

• Main/standby operation or parallel operation (for automatic system fault condition-actuated switchover/elapsed operating 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 in compliance with 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 in compliance with 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
