TOP-Z

Design

Glandless circulator with screwed connection or flange connection. Pre-selectable speed stages for power adjustment

Application

Domestic hot water circulation systems in industry and building services.

Equipment/function

Operating modes

Speed-stage switching

Manual functions

Setting the speed stages: 3 speed stages

Automatic functions

Internal protection against unacceptably high winding temperatures (only for pumps with P2 < 180 W, optional for all types with switchgears SK 602N and SK 622N).

Signal and display functions

Thermal winding contact (WSK, potential-free NC contact) (only for pumps with P2 ≥ 180 W)
Direction of rotation signal lamp (only for 3~ pumps)

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 pumps DN 80: PN 6 flange (designed for PN 16 according to EN 1092-2) for PN 6 counter flange
- Special version for DN 40 to DN 80 pumps: PN 16 flange (according to EN 1092-2) for PN 16 counter flange,
Cable inlet possible from both sides (only for 1~pumps and 3~pumps with P2≥180 W)
Thermal insulation as standard
