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), 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 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. +90 °C ... +110 °C and also if there is oil 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:

  • 1 Mounting bracket with fixation material for installation on a base
  • Installation aid for mechanical seal
  • IR-Stick
  • IF module PLR for connecting to PLR/interface converter
  • IF module LON for connection to the LONWORKS network
  • IF module BACnet
  • IF module Modbus
  • IF module CAN
  • Control system VR-HVAC
  • Control system CCe-HVAC
  • Control system SCe-HVAC
  • Differential pressure sensor (DDG)

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 (for Y-piece installation only: main/standby operation, parallel operation)

Additional functions:

Interfaces:

  • 1x “Overriding Off” control input,
  • 1x “External pump cycling” (effective only in twin-head pump operation),
