In-line pump with high energy efficiency with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2, hydraulics with minimum efficiency index MEI ≥ 0.4 and electronic power adjustment in glanded pump design. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Yonos GIGA2.0-D has been predominantly designed for pumping heating water (acc. to VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, air conditioning and cooling systems.

Design ...-R1-S1

• Single-stage low-pressure centrifugal pump with one-piece shaft in close-coupled design
• Spiral housing in in-line design (suction and discharge ports with the same flanges in a line)
• PN 16 flange – in accordance with EN 1092-2
• Pressure measuring connections (R 1/8) for retrofitting of a differential pressure sensor (version ...-R1 without differential pressure sensor)
• Pump housing and lantern/motor flange with cataphoretic coating as standard
• Mechanical seal S1 recommended for water-glycol mixtures with glycol proportions up to max. 50% by volume and a fluid temperature of -20 °C up to max. +90 °C – +110 °C and also if there is oil in the water-glycol mixture.
• Connection voltages:
  • 3~440 V ±10 % 50/60 Hz; 3~400 V ±10 % 50/60 Hz; 3~380 V -5 % +10 % 50/60 Hz
  • Version M-: 1~220 V … 240 V (±10%), 50/60 Hz
• Compliance with electromagnetic compatibility without additional measures
  • Interference emission for residential environment according to EN 61800-3:2018
  • Interference immunity for industrial environments according to EN 61800-3:2018

Control modes:

• Variable differential pressure (dp-v)
• Constant differential pressure (dp-c)
• Constant speed (n-const.)
• User-defined PID control
• Only possible with differential pressure sensor:
  • Variable differential pressure (dp-v)
  • Constant differential pressure (dp-c)

Functions:

• Operating modes of twin-head pump: Main/standby operation, efficiency-optimised parallel operation for dp-c and dp-v
• Integrated full motor protection
• Only possible with differential pressure sensor:
  • Efficiency-optimised parallel operation for dp-c and dp-v
