Design
Electronically controlled glanded single pump in close-coupled design with flange connection and automatic power adjustment.

Application
The pumping of heating water (in accordance with VDI 2035), chilled water and water-glycol mixtures without abrasive substances in heating, chilled water and cooling systems.

Equipment / Function
Operating modes

• Δp-c for constant differential pressure
• Δp-v for variable differential pressure
• PID-Control
• Constant speed (n = constant)

Manual operation level

• Green button and display

Manual functions

• Differential pressure setpoint setting
• Setting the speed (manual control mode)
• Setting the operating mode
• Setting the pump ON/OFF
• Configuration of all operating parameters
• Fault acknowledgement

External control functions

• 1x “Overriding Off” control input
• 1x “External pump alternation” control input (effective only in twin-head pump operation)
• 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for constant speed (DDC) and remote setpoint adjustment
• 1x Analogue input 0–10 V, 2–10 V, 0–20 mA, 4–20 mA for actual value signal from pressure sensor

Signal and display functions

• Collective fault signal SSM

Dual-pump management (2 x single pump; Y-piece application only)

• Main/standby operation (automatic fault-actuated switchover)
• Pump alternation main/standby operation after 24 hours
• Parallel operation
• Parallel operation (efficiency-optimised peak load activation and deactivation)

Type key (example)
Example: BL-E 80/145-11/2-xx where BL-E = Close-coupled end suction pump with electronic control; 80 = nominal diameter DN of the pipe connection (discharge port); 145 = nominal impeller diameter in mm; 11 = rated power of motor P2 in kW; 2 = number of poles; -xx = version (e.g. R1 = version without differential pressure sensor).
