Wilo-TOP-S

Design

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


Type key

Example:TOP‐S 40/10
TOP-SStandard pump (screw-end pump or flange-end pump)
40/Nominal connection diameter
10Nominal delivery head [m] at Q = 0 m3/ h


Special features/product advantages

  • Collective fault signal as potential-free contact (depending on type)
  • Direction of rotation indicator light for displaying the correct sense of rotation (only with 3~)
  • Pump housing with cataphoretic (KTL) coating protects against corrosion due to condensation formation


Technical data

  • Permitted temperature range -20 °C to +130 °C,
    for short periods (2 h) up to +140 °C (TOP-S 25/13, 80/15, 80/20 and pumps with Wilo-Protect-Module: -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, standard version: 6/10 bar or 6 bar (special version: 10 bar or 16 bar)


Equipment/function

Operating modes
  • Speed-stage switching

Manual functions
  • Setting of the speed stages: 3 speed stages (2 speed stages for 1~pumps with P2 ≥ 350 W)

Automatic functions
  • Full motor protection with integrated trip electronics (standard equipment only for 3~pumps with P2 ≥ 180 W and 1~pumps with P2 ≥ 350 W, optional for all types with Wilo-Protect-Module C)

External control functions
  • "Overriding Off" control input (optional for all types with Wilo-Protect-Module C)

Signal and display functions
  • Individual/collective fault signal (potential-free NC contact) (optional for all types with Wilo-Protect-Module C)
  • Collective fault signal (potential-free NC contact) (standard equipment only with 3~ pumps with P2 ≥ 180 W and 1~ pumps with P2 ≥ 350 W, optional in all types with Wilo-Protect-Module C)
  • Individual run signal (potential-free NO contact) (optional for all types with Wilo-Protect-Module C)
  • Thermal winding contact (WSK, potential-free NC contact) (only for 1~pumps with P2 = 180 W)
  • Fault signal light (standard equipment only for 3~pumps with P2 ≥ 180 W and 1~pumps with P2 ≥ 350 W, optional for all types with Wilo-Protect-Module C)
  • Direction of rotation control light (only for 3~pumps )

Dual pump management (double pump or 2 x single pump)
  • Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling): optional for all types with Wilo-Protect-Module C

Equipment
  • In flange pumps: Flange versions
    • Standard version for pumps DN 40 to DN 65: Combination flange PN 6/10 (flange PN 16 acc. to EN 1092-2) for counter flanges PN 6 and PN 16,
    • Standard version for pumps DN 80 / DN 100: Flange PN 6 (configured for PN 16 acc. to EN 1092-2) for counter flange PN 6,
    • Special version for pumps DN 40 to DN 100: Flange PN 16 (acc. to EN 1092-2) for counter flange PN 16,
  • Cable lead-in possible from both sides (only for 1~pumps and 3~pumps with P2 ≥ 180 W)
  • Standard thermal insulation for heating applications
