Tender text

This circulator is suitable only for drinking water.

Maintenance-free domestic hot water circulator (glandless twin-head pump) with screwed connection, blocking-current proof synchronous motor according to ECM technology and built-in electronic power control for continuous differential pressure control. Suitable for all domestic hot water systems (+2 to +95 °C).

Each pump can be operated in individual operation (main/standby operation) or both pumps can be operated at the same time in parallel operation (parallel/peak-load operation).

All control modes are possible (Δp-c, constant speed, 3 fixed speed stages C1, C2, C3), but the settings must be identical for both pumps.

For an automatic fault-actuated switchover, a corresponding switchgear must be provided on-site.

Standard-equipped with:

  • Preselectable control modes for optimum load adjustment:
    • Δp-c for constant differential pressure
    • Constant speed (3 constant speed stages)
    • Constant speed (continuously adjustable)
  • LED display for setting the setpoint, displaying current consumption in watts and flow rate in m³/h
  • Integrated motor protection
  • Automatic deblocking function
  • Manual pump venting function for venting the rotor chamber
  • Manual restart
  • Pump housing made of stainless steel
  • Quick electrical connection with Wilo-Connector
