High-efficiency in-line pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2, hydraulics with minimum efficiency index MEI ≥ 0.7 and electronic power adjustment in glanded pump construction. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Stratos GIGA2.0-D has been predominantly designed for pumping heating water (acc. to VDI 2035), cold water and water-glycol mixtures without abrasive substances in heating, air-conditioning and cooling systems.

  • Single-stage low-pressure centrifugal pump with one-piece shaft in monobloc 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 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.

Commissioning Glanded pumps

For perfect functioning of the pump(s) / system(s), it is recommended to have the commissioning carried out by the works' own WILO SE Customer Service Department. Optimum setting and efficient operation of the system are ensured as a result. Commissioning is comprised of the following points:

  • Commissioning of system(s) according to checklist
  • Parameterisation and setting of switchgear
  • Testing and adaptation of initial compressing of pressure tanks (filling up to 80 litres incl.)
  • Functional check of fitted system(s)
  • Practice-oriented operation instruction
  • Wilo commissioning protocol

The price for commissioning only applies to system(s) which have been installed in accordance with the installation and operating instructions and state-of-the-art technology. No costs for any materials which may be required are included.
