Wilo-Stratos high-efficiency pump

electronically controlled,

Glandless circulation pump with minimum operating costs, for pipe installation. Can be used for all HVAC applications (-10 °C to +110 °C). With built-in electronic power control for constant/variable differential pressure. Standard-equipped thermal insulation shells. One-button manual operation level as standard, for:

  • Pump On/Off
  • Selecting the control mode:
    • dp-c (differential pressure constant )
    • dp-v (differential pressure variable)
    • dp-T (differential pressure temperature-controlled) by means of IR-Monitor/IR-Module/IR-Stick, Modbus, BACnet, LON or Can
    • Q-Limit to restrict the maximum volume flow (setting only via IR-Stick)
    • Manual control mode (setting constant speed)
  • Automatic setback operation (self-learning)
  • Setpoint or speed adjustment

Graphical pump display with rotatable display horizontal and vertical module mounting, for display of:

  • Operating status
  • Control mode
  • Differential pressure or rotation speed setpoint
  • Fault and alarm signals

Synchronous motor using ECM technology with very high efficiency and high starting torque, automatic deblocking function and built-in full motor protection.

Fault signal light, potential-free collective fault signal, infrared interface for wireless communication with Wilo IR-Monitor/IR-Stick operating and service device.

Plug-in slot for Wilo Stratos IF-modules with interfaces for building automation (BA) or dual pump management (accessories: IF-modules Stratos Modbus, BACnet, LON, CAN, PLR, Ext.Aus, Ext.Min, SBM, Ext.Aus/SBM or DP).

Pump housing made of cast iron with cataphoretic coating, impeller made of glass-fibre reinforced plastic, stainless steel shaft with metal impregnated carbon plain bearings.

For flange-end pumps - flange versions:

  • Standard version for pumps DN 32 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 32 to DN 100: Flange PN 16 (acc. to EN 1092-2) for counter flange PN 16
