Series description

Design

High-efficiency, fully automatic, ready-for-connection multi-pump system for high volume flows in heating, chilled water and cooling systems. 3 to 4 electronically controlled, glanded in-line pumps connected in parallel from the Yonos GIGA2.0-I series. One of these pumps acts as a standby pump. Incl. Smart Controller SCe.

Application

For pumping heating water (in accordance with VDI 2035), water-glycol mixtures, cooling water and cold water without abrasive substances in heating, chilled water and cooling systems.

Equipment/function

  • 3-4 pumps per system of the Yonos GIGA2.0-I series, of which 2 or 3 pumps in operation, 1 standby pump
  • IE5 motor
  • Automatic pump control via Smart Controller SCe
  • Parts that come in contact with the fluid are corrosion-resistant
  • Base frame made of galvanised steel, with height-adjustable oscillation absorbers for insulation against structure-borne noise
  • Steel distributor, corrosion-resistant coating
  • Flanges PN 16 to EN 1092-2 on the pressure and suction side for connection to the pipeline system
  • Pre-assembled seals on the pressure and suction side
  • Shut-off devices on the suction and discharge side
  • Non-return valve on the discharge side
  • Differential pressure sensor
  • Pressure gauge on both pressure and suction side
