TOP-S Circulating Pump

Technical Data:

  • Permitted temperature range -20 °C to +130 °C, for short periods (2 h) to +140 °C (TOP-S 25/13, 80/15, 80/20: -20 °C to +110 °C)
  • Mains connection:
    • 1~230 V, 50 Hz (depending on type)
    • 3~230 V, 50 Hz (with optional switching plug)
    • 3~400 V, 50 Hz
  • Protection class IP X4D
  • Screwed connection or flange connection (depending on type) Rp 1 to DN 100
  • Max. operating pressure of standard version: 6/10 bar or 6 bar (special version: 10 bar)

  • 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
