Stratos GIGA B 32/7-92/18,5

High-efficiency close-coupled pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2 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 Stratos GIGA B 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:

• Single-stage low-pressure centrifugal pump with one-piece shaft in close-coupled design including foot on pump housing
• Flange and housing measurements according to EN 733
• PN 16 flange – drilled according to EN 1092-2
• Pressure measuring connections (R 1/8) for mounted differential pressure sensor (version ...-R1 without differential pressure sensor)
• Pump housing and motor flange with cataphoretic coating as standard
• Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
• Connection voltages: 3~480 V ±10 % 50/60 Hz; 3~440 V ±10 % 50/60 Hz; 3~400 V ±10 % 50/60 Hz; 3~380 V -5 % +10 % 50/60 Hz
