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.
Design ...-S1:
- 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 mounted 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. +110 °C and also if there is oil in the water-glycol mixture.

- Adjustable volume flow limiter using the Q-Limit function (Qmin. and Qmax.)
- Operating modes of twin-head pump: Main/standby operation, efficiency-optimised parallel operation for dp-c and dp-v
- Pump automatically deactivates when no flow is detected (No-Flow Stop)
- Switchover between heating and cooling mode (automatic, external or manual)
- Ability to save and restore configured pump settings (3 restoration points)
- Display of current duty point in the hydraulic duty chart
- Correction of viscous fluids via adjustment of viscosity and density
- Fault and warning messages shown in plain text with advice on resolving the issue
- Integrated full motor protection
