Design

Glandless circulation double pump with screwed connection, blocking-current proof EC motor and integrated electronic power control.

Application

All hot water heating systems, air-conditioning applications, industrial circulation systems.

Type key

Special features/product advantages

• LED display for adjusting the setpoint in 0.1 m increments and showing effective consumption
• Tool-free electrical connection using the Wilo-Connector
• Unique pump venting function per pump
• Double pump for individual (Δp-c and Δp-v) or parallel operation (Δp-c)
• Very high starting torque for reliable starting

Technical data

Energy efficiency index (EEI) from ≤ 0.23

Equipment/function

Operating modes

• Δ p-c for constant differential pressure
• Δ p-v for variable differential pressure

Manual functions

• Setting the operating mode
• Setting of pump output (delivery head)
• Venting function

Automatic functions

• Infinitely variable power adjustment according to the operating mode
• Automatic deblocking function

Signal and display functions

• Display of power consumption in W
• Display of the current pumping head for setting
• Indication of fault signals (error codes)

Equipment

• Quick electrical connection with Wilo-Connector
• Venting function
• Blocking-current proof motor
• Particle filter

Double pump function

• Main/standby mode (automatic fault-actuated switchover/time-dependent pump cycling). If the double pump is to be operated in the main/standby mode, the control mode and the delivery head must be set so they are identical.
• Parallel operation (efficiency-optimised peak-load activation and deactivation). If the double pump is to be operated in parallel/peak-load operation, the control mode Δp-c must be set with the same delivery head.

An additional switchgear is required for switching the pumps, e.g. in the event of a fault.
