More about this product
Overview
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 design. 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.

Features and equipment
Design
- 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 – drilled according to EN 1092-2
- Pressure measuring connections (R 1/8) for mounted differential pressure sensor (…-R1 version 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 maximum 50 % by volume and a fluid temperature of > +40 °C up to maximum +120 °C or fluids other than water.
- 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
