Overview

Direction of rotation indicator lamp for indicating the correct direction of rotation (only on 3~)
With thermal insulation as standard.

Type

Glandless circulation pump with threaded connection or flange connection. With variable speed step selection possible

Application

Drinking water circulators, industrial applications and building services equipment.

Equipment/function

Mode of operation

Switching speed steps

Manual control

Speed step setting: 3 speed steps

Automatic control

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

Indication and signalling

Winding protection contact (WSK, potential free normally closed contact) (only for pumps with P2 ≥ 180 W)
Pilot indicator light for direction of rotation (only for 3~pumps)

Accessories

For pumps with flange connection: flange version
- Standard version for pumps DN 40 to DN 65: Combination flange PN 6/10 (flange PN 16 as per EN 1092-2) for counter flanges PN 6 and PN 16
- Standard version for pumps DN 80: Flange PN 6 (designed for PN 16 acc. to EN 1092-2) for counter flange PN 6,
- Special version for pumps DN 40 to DN 80: Flange PN 16 (acc. to EN 1092-2) for counter flange PN 16,
- Cable entry is possible on both sides (only for 1- and 3-phase pumps with P2 ≥ 180 W)
Thermal insulation as standard
