Wilo-Stratos

Wilo-Stratos Glandless circulation pump with threaded or flange connection, electronically commutated motor with automatic speed control.

Overview

  • Energy savings due to increased system efficiency with Q-Limit function (flow limitation)
  • Improved energy efficiency index EEI ≤0.20 for all single pumps
  • Optimised display for improved readability and control
  • Space-saving installation due to compact design and position-independent LCD display
  • Modular concept for connection to all common bus systems (e.g. Modbus, BACnet, CAN, LON, PLR)
  • Proven quality and reliability
  • Withdrawal program
  • After 19 years of success, the Wilo-Stratos high-efficiency pump will be completely removed from the product range by the end of March 2020 and replaced by the new Wilo-Stratos MAXO smart pump. The new Wilo-Stratos MAXO pump technology will continue the success of the Stratos series.

Type
Glandless circulation pump with threaded connection or flange connection, EC motor with automatic speed control.

Application

  • All hot water heating systems, air-conditioning systems, closed cooling circuits, industrial circulation systems.
  • Equipment/function

Modes of operation

  • Manual operation (n = constant)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • Δp-T for differential pressure dependent on temperature control (programmable via IR-Stick, IR-Monitor, Modbus, BACnet, LON or CAN)
  • Q-Limit to limit max. flow (can only be set on the IR-Stick)

Manual control

  • Setting of operating modes
  • Setting the flow rate value
  • Setting for automatic speed reduction mode
  • Pump ON/OFF setting
  • Speed setting (manual switch-over)

Automatic control

  • Infinitely variable speed control according to mode of operation
  • Automatic downmilling operation
  • Lockout function
  • Soft start
  • Full motor protection with integrated electronic shutdown

External control

  • Priority off control input (possible with Stratos IF-modules)
  • Minimum power priority input (available with Stratos IF-modules)
  • Control input "Analog In 0 - 10V" (remote speed switching), possible with Stratos IF-modules
  • Control input "Analog In 0 - 10 V" (remote setpoint adjustment), possible with Stratos IF-modules

Alarms and display

  • Generalized fault indication (potential free NO contact)
  • Separate fault indication (potential free normally open contact), possible with Stratos IF-Modules
  • Lighted fault indicator
  • LCD display for the indication of pump parameters and error codes

Data exchange

  • Infra-red interface for wireless data exchange with IR-Stick/IR monitor
  • Modbus RTU serial digital interface for connection to a building automation system via RS485 bus system (possible with Stratos IF-modules)
  • BACnet MS/TP Slave serial digital interface for connection to a building automation system via RS485 bus system (possible with Stratos IF-modules).
  • CAN serial digital interface for connection to a building automation system via a bus system (possible with Stratos IF-modules).
  • LON serial digital interface to connect to a LONWorks network (available with Stratos IF-Modules)
  • PLR serial digital interface for connection to a building automation system via a Wilo interface converter or special communication modules (available with Stratos IF-Modules)

Twin pump control (twin pump or two single pumps)

  • Main/standby operation (automatic switchover in the event of malfunction/pump timer operation): various combinations with Stratos IF-Modules (accessories) possible
  • Dual pump operation (switch-on second pump during peak demand with efficiency optimisation): various combinations with Stratos IF-Modules (accessories) possible

Accessories

  • Keyed casting on pump casing (for pumps with threaded pipe connection P2< 100 W)
  • For pumps with flange connection: flange version
  • Standard version for pumps DN 32 to DN 65: Combination flange PN 6/10 (flange PN 16 as per EN 1092-2) for counter flanges PN 6 and PN 16
  • Standard version for pumps DN 80/DN 100: Flange PN 6 (designed PN 16 as per EN 1092-2) for counter flange PN 6
  • Special version for pumps DN 32 to DN 100: Flange PN 16 (acc. to EN 1092-2) for counter flange PN 16
  • Socket for the optional addition of Wilo IF-Modules
  • Thermal insulation for pumps used in heating systems as standard
