Technical data
Tender text

High-efficiency monobloc pump with EC motor of energy efficiency class IE5 in accordance with IEC 60034-30-2 and electronic power adjustment in glanded pump design. The pump is configured as a single-stage low-pressure centrifugal pump with flange connection and mechanical seal. The Stratos GIGA B 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:

  • 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 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. +120 °C and also for oil proportions in the water-glycol mixture.
  • 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 kits 0 – 10 V for pumps in version ...-R1
  • IR-Monitor
  • 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 displaying:
    • 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 (for Y-piece installation only: main/standby operation, parallel operation)

Additional functions:

  • Analogue interfaces 0-10 V, 2-10 V, 0-20 mA, 4-20 mA, built-in dual pump management for application in the Y-piece, 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, slot for Wilo IF module Modbus, BACnet, CAN, PLR, LON for connecting to the building automation.
