Wilo-Stratos D high-efficiency pump

electronically controlled,

Glandless double 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. One-button manual operation level for each pump as standard, for:

  • Pump on/off
  • Selecting the operating mode: Main/standby operation, parallel operation (efficiency-optimised peak load cut-in / deactivation)(accessories: 2 pcs. Stratos IF-modules necessary)
  • 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 and speed adjustment

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

  • Operating state
  • Control mode
  • Differential pressure or rotation speed setpoint
  • Fault and warning signals
  • Double-pump operating mode

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: 2 pcs 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.
