Wilo-Stratos GIGA

High-efficiency inline pump with EC motor and electronic duty adaptation in glanded construction. Version as single-stage low-pressure centrifugal pump with flange connection and mechanical shaft seal.

Pumping of heating water (acc. to VDI 2035), chilled water and water/glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Operating modes

• Δp-c for constant differential pressure
• Δp-v for variable differential pressure
• PID control
• Constant speed (n=constant)

Manual operation level

• Green button and display

Manual functions

• Differential pressure setpoint setting
• Setting the speed (manual control mode)
• Setting the operating mode
• Setting the pump ON/OFF

• Fault acknowledgement

External control functions

• "Overriding Off" control input
• “External pump cycling” control input (effective only in dual pump operation)
• Analogue input 0 – 10 V, 0 – 20 mA for constant speed (DDC) and remote setpoint adjustment
• Analogue input 2 – 10 V, 4 – 20 mA for constant speed (DDC) and remote setpoint adjustment
• Analogue input 0 – 10 V for actual value signal from pressure sensor
• Analogue input 2 – 10 V, 0 – 20 mA, 4 – 20 mA for actual value signal from pressure sensor

Signal and display functions

• Collective fault signal SSM
