Stratos GIGA2.0-D 50/1-8/M-0,37

High-efficiency pump as twin-head pump with EC motor of efficiency class IE5 in accordance with IEC 60034-30-2, hydraulic minimum efficiency index MEI ≥ 0.7 or MEI ≥ 0.4 (depending on the pump type) 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 GIGA2.0-D 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 or split shaft (depending on the pump type)
• Volute 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 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:
  • 3~440 V ±10% 50/60 Hz; 3~400 V ±10% 50/60 Hz; 3~380 V -5% +10% 50/60 Hz
  • Variant M-: 1~220 V – 240 V (±10%), 50/60 Hz
• Compliance with electromagnetic compatibility without additional measures
  • Interference emission for residential environment according to EN 61800-3:2018
  • Interference immunity for industrial environments according to EN 61800-3:2018

Control modes:

• Permanent, automatic power adjustment to system requirements without setpoint specification Wilo Dynamic Adapt plus (factory setting).
• Constant temperature (T-const.)
• Constant differential temperature (dT-const.)
• Demand-based volume flow optimisation of the feeder pump through connectivity and communication between multiple secondary pumps (Multi-Flow Adaptation).
• Constant volume flow (Q-const.)
• Variable differential pressure (dp-v) with the option to set the nominal duty point Q and H
• Constant differential pressure (dp-c)
• Differential pressure control (dp-c) to a remote point in the pipe network (index circuit evaluator)
• Constant speed (n-const.)
• User-defined PID control

Functions:

• Selection of the field of application in the setting assistant
• Heat quantity measurement
• Cooling quantity measurement
• Adjustable volume flow limiter using the Q-Limit function (Q_min. and Q_max.)
• Operating modes of twin-head pump/two-pump system: Main/standby operation, efficiency-optimised parallel operation for dp-c and dp-v
• Pump automatically deactivates when no flow rate 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

• 2 configurable digital inputs (Ext. OFF, Ext. Min, Ext. Max, heating/cooling, manual override (uncoupled from building automation), operation lock (key lock and remote operation configuration protection))
• 2 configurable signal relays for run signals and fault messages
• Slot for Wilo-CIF modules with interfaces for building automation (BA) (optional accessories: CIF modules Modbus RTU, BACnet MS/TP, LON, PLR, CAN)
• Wilo Net as a Wilo system bus for communication between Wilo products, e.g. Multi-Flow Adaptation; dual-pump operation
• Automatic emergency operation with definable pump speed for exceptional circumstances, e.g. bus communication or sensor value malfunction
• Rotatable, graphic colour display (4.3 inches) with one button manual operation level
• Bluetooth interface via Wilo-Smart Connect module BT
• Use the Wilo-Assistant app to read and set operating data and –among other things– set up a commissioning protocol through the Bluetooth interface
