Stratos GIGA 40/1-51/4,2

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 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 – 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 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

Accessories:

• Mounting brackets for fixing to the foundation
• Differential pressure sensor sets 0 – 10 V for pumps in ...–R1 version
• IR-Stick
• IF module PLR
• IF module LON
• IF module Modbus
• IF module BACnet
• IF module CAN

Standard equipment:

• Green button manual operation level for:
  • Pump On/Off
  • Selecting the control mode: Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (constant speed)
  • Setpoint and speed adjustment
  • Configuration of operating parameters
  • Fault acknowledgement
• Pump display for indication of:
  • Control mode
  • Setpoint (e.g. differential pressure or speed)
  • Error and warning messages
  • Actual values (e.g. power consumption, actual value of the sensor)
  • Operating data (e.g. operating hours, energy consumption)
  • Status data (e.g. status of SSM and SBM relay)
  • Device data (e.g. pump name)
  • Operating mode (only for dual-pump operation: main/standby operation, parallel operation)
  • Status of the pressure values correction

Additional functions:

• Analogue interfaces 0-10 V, 2-10 V, 0-20 mA, 4-20 mA, built-in dual-pump management, two configurable signalling relays for run signals and fault messages, configurable fault response adapted to HVAC applications, access disable on the pump, built-in full motor protection (PTC thermistor sensor) with trip electronics, condensation drain holes in the motor housing as standard (sealed in delivered condition), infrared interface for wireless communication with the operating and service unit Wilo-IR-Monitor and Wilo-IR-Stick, plug-in position for Wilo IF Module Modbus, BACnet, CAN, PLR, LON for connecting to the building automation.
