Wilo-Stratos

Design

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


Application

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


Type key

Example:Wilo-Stratos 30/1-12
StratosHigh-efficiency pump (screw-end or flange-end pump), electronically controlled
30/Nominal connection diameter
1-12Nominal delivery head range [m]


Special features/product advantages

  • Used in heating, cooling and air-conditioning systems from -10 °C to +110 °C
  • Very high efficiency due to ECM technology
  • Front operation and access to terminal room, variable installation positions, display independent of position
  • Simple installation and commissioning thanks to "red-button technology“
  • Communication-capable for building automation in all system environments thanks to retrofittable interface modules


Technical data

  • Energy efficiency index (EEI) ≤ 0.23
  • Permissible temperature range ‐-10°C to +110°C
  • Mains connection 1~230 V, 50/60 Hz
  • Protection class IP X4D
  • Screwed connection or flange connection (depending on type) Rp 1 to DN 100
  • Max. operating pressure, standard version: 6/10 bar or 6 bar (special version: 10 bar or 16 bar)


Equipment/function

Operating modes
  • Manual control mode (n=constant)
  • Δp-c for constant differential pressure
  • Δp-v for variable differential pressure

  • "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
  • LC display for indication of pump data and fault 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 (double pump or 2 x single pump)
  • 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
