High-efficiency in-line pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2 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 GIGA 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
– Spiral housing in in-line design (suction and discharge ports with the same flanges in one line), flanges PN 16 – drilled acc. 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. A glycol admixture of 20 % to +40 % by volume is permitted up to T ≤ +40 °C. An alternative mechanical seal must be provided in water-glycol mixtures with glycol proportions > 40 % up to max. 50 % by volume and a fluid temperature of > +40 °C up to max. +120 °C or fluids other than water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
– Connection voltages: 3~380 V +-10% 50/60 Hz; 3~400 V +-10% 50/60 Hz; 3~440 V +-10% 50/60 Hz

– Adjustable time interval for pump cycling (in dual-pump operation)
– Integrated full motor protection
– Different operating modes for heating (HV) or air-conditioning (AC) applications
– Access disable
– Different operation levels: Standard/service
