High-efficiency monobloc pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2 and electronic power adjustment with a glanded pump design. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Stratos GIGA2.0-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 monobloc 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. A glycol admixture of 20% to 40% by volume is permissible up to T ≤ +40 °C. 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:
– 3~440 V +-10% 50/60 Hz; 3~400 V +-10% 50/60 Hz; 3~380 V -5% +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.)
– Needs-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 (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
