Stratos Circulating Pump

Technical Data:

  • Permissible temperature range -10 °C to +110 °C.
  • Mains connection 1~230 V, 50/60 Hz.
  • Protection class IPX4D.
  • Screwed connection or flange connection (depending on type) Rp 1 to DN 100.
  • Max. operating pressure of standard version: 6/10 bar or 6 bar (special version: 10 bar or 16 bar).

  • Energy savings due to greater system efficiency with the Q-Limit function (volume flow limiter).
  • Improved Energy Efficiency Index (EEI) ≤ 0.20 for all single pumps.
  • Enhanced display for better readability and ease of operation.
  • Space-saving installation thanks to compact design and variable-orientation LC display.
  • Modular concept for connection of all conventional bus systems (e.g. Modbus, BACnet, CAN, LON and PLR).
  • Tried-and-tested quality and reliability.

 

Phasing Out Program:

After 19 successful years, the Wilo-Stratos high-efficiency pump will be removed from our product range at the end of the year. It will be fully superseded by the new Wilo-Stratos MAXO smart pump. The successful era of the Stratos series will continue with the Stratos MAXO’s new pump technology.

 

Construction:

Glandless circulator with threaded connection or flange connection, EC motor with automatic power adjustment.

 

Materials:

  • Pump housing: grey cast iron with cataphoretic coating.
  • Thermal insulation: polypropylene.
  • Shaft: Stainless steel.
  • Bearing: carbon, metal impregnated.
  • Impeller: Plastic.

 

Application:

Hot-water heating systems of all kinds, air-conditioning systems, closed cooling circuits, industrial circulation systems.

  • Glandless circulator with EC motor and integrated automatic power adjustment
  • Green Button Technology and graphic display
  • Motor protection with trip electronics
  • Plug connection for functional extension with optional IF module for building automation (BA)
  • Impeller with three-dimensionally curved blades and plastic sealing tube made of carbon fibre composite material

Operating Modes:

  • Constant speed (n=constant)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure
  • Δp-T for temperature-controlled differential pressure (programmable via IR-Stick, IR-Monitor, Modbus, BACnet, LON or CAN)
  • Q limit for limiting the maximum volume flow (setting only via IR-stick)

 

Manual Functions:

  • Setting the operating mode
  • Differential pressure setpoint setting
  • Setting automatic setback operation
  • Setting the pump ON/OFF
  • Setting the speed (manual control mode)

 

Automatic Functions:

  • Continuous power adjustment according to the operating mode
  • Automatic setback operation
  • Deblocking function
  • Soft start
  • Full motor protection with integrated trip electronics

 

External Control Functions:

  • "Overriding Off" control input (possible with Stratos IF-Modules)
  • "Overriding Min" control input (possible with Stratos IF-Modules)
  • "Analogue In 0 - 10 V" control input (remote speed adjustment) (possible with Stratos IF-Modules)
  • "Analogue In 0 - 10 V" control input (remote setpoint adjustment) (possible with Stratos IF-Modules)

 

Signal and Display Functions:

  • Collective fault signal (potential-free NC contact)
  • Individual run signal (potential-free NO contact) (possible with Stratos IF-Modules)
  • Fault signal light
  • LCD display for indication of pump data and error codes

 

Data Exchange:

  • Infrared interface for wireless data exchange with IR-Stick/IR-Monitor
  • Modbus RTU serial digital interface for connection to building automation BA via RS485 BUS system (possible with Stratos IF-Modules)
  • BACnet serial digital interface MS/TP Slave for connection to building automation BA via RS485 BUS system (possible with Stratos IF-Modules)
  • CAN serial digital interface for connection to building automation BA via CAN BUS system (possible with Stratos IF-Modules)
  • LON serial digital interface for connection to a LONWorks network (possible with Stratos IF-Modules)
  • PLR serial digital interface for connection to BA via Wilo interface converter or company-specific coupling modules (possible with Stratos IF-Modules)

 

Dual pump management (twin-head pump or 2 x single pumps):

  • Main/standby operation (automatic fault-actuated switchover/time-dependent pump cycling): various combinations with Stratos IF-Modules (accessories) possible
  • Parallel operation (efficiency-optimised peak load activation and deactivation): various combinations with Stratos IF-Modules (accessories) possible

 

Equipment:

  • Wrench attachment point on pump body (for threaded pipe union pumps with P2 < 100 W)
  • For flange-end pumps: Flange versions
  • Standard version for DN 32 to DN 65 pumps: PN 6/10 combination flange (PN 16 flange according to EN 1092-2) for PN 6 and PN 16 counter flanges
  • Standard version for DN 80/DN 100 pumps: PN 6 flange (designed for PN 16 according to EN 1092-2) for PN 6 counter flange
  • Special version for DN 32 to DN 100 pumps: PN 16 flange (according to EN 1092-2) for PN 16 counter flange
  • Plug-in position for optional extension with Wilo-IF-Modules
