Centrifugal pump Yonos GIGA-N series

glycol waterwith electric motornormal priming

Overview
The Wilo‑Yonos GIGA‑N is a high‑efficiency, single‑stage centrifugal baseplate pump designed for heating, air‑conditioning and cooling systems that require moving large water volumes at high delivery heads.

Key features

• IE4 efficiency class motors
• Cataphoretic coating on all cast components for enhanced corrosion resistance
• Standardised dimensions according to EN 733 for universal replacement
• Green Button Technology for simple adjustment and clear display
• Back‑pull‑out spacer coupling for easy maintenance (option: variant without spacer coupling)
• Plug‑in slot for IF modules (Modbus, BACnet, CAN, PLR, LON) for building automation

Design
Electronically controlled, single‑stage low‑pressure centrifugal pump with axial suction, mounted on a baseplate with flanged connections. Integrated electronic speed control optimises power consumption according to demand.

Applications

• Pumping heating water (VDI 2035), chilled water and water‑glycol mixtures without abrasive substances
• Building services (heating/chilled water/cooling), irrigation, general industry, power stations

Equipment / Functions

• Drive with integrated electronic speed control (multiple operating modes)
• Mechanical seal (standard AQEGG; alternatives on request)
• Infrared interface for wireless parameter exchange
• Plug‑in position for Wilo IF modules

Operating modes & control

• Δp‑c (constant differential pressure)
• PID‑Control
• Constant speed (n = constant)
• Manual operation via Green Button and display: setpoint, speed, mode selection, ON/OFF, parameter configuration, fault acknowledgement
• External control inputs: “Overriding Off”, analogue inputs 0–10 V / 0–20 mA / 2–10 V / 4–20 mA for remote setpoint and actual value signals
