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
  • Spiral housing in in-line design (suction and discharge ports with the same flanges in one line), flanges PN 16 – drilled acc. 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 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: 3~380 V ±10% 50/60 Hz; 3~400 V ±10% 50/60 Hz; 3~440 V ±10% 50/60 Hz

Accessories:

  • Mounting brackets for fixing to the foundation
  • IR-Stick
  • IF module PLR
  • IF module LON
  • IF module Modbus
  • IF module BACnet
  • IF module CAN
  • Control systems VR-HVAC/CCe-HVAC/SCe-HVAC
  • Differential pressure sensor (DDG) sets 0-10 V for pumps in version ...-R1

Standard equipment:

  • One-button manual operation level for:
    • Pump On/Off
    • Setpoint and speed adjustment
    • Selecting the control mode: Δp-c (constant differential pressure), Δp-v (variable differential pressure), PID controller, n-constant (constant speed)
    • Selection of operating mode in dual-pump operation (main/standby operation, parallel operation)
    • 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)

Additional functions:

  • Interfaces: Control input “Overriding Off”, “External pump cycling” (effective only in dual-pump operation), analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) or for remote setpoint adjustment, analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal of the pressure sensor, infrared interface for wireless communication with the operating and service device Wilo-IR-Stick, slot for Wilo IF modules for connecting to the building automation, configurable, potential-free fault and operating/ready message, interface for dual-pump communication

  • Integrated full motor protection
  • Different operating modes for heating (HV) or air-conditioning (AC) applications
  • Access disable
  • Different operation levels: Standard/service
