Wilo DL-E 100/145-11/2-S1

Wilo DL-E 100/145-11/2-S1 Dry-Running Twin Pump

Dry-running inline twin pump for pipeline installation or foundation mounting with integrated frequency converter for electronic control, including constant or variable differential pressure regulation (Δp-c/Δp-v).

Design
Electronically controlled dry-running twin pump in inline design with flange connection and automatic power adjustment.

Applications
Pumping of heating water (as per VDI 2035), cold water, and water-glycol mixtures without abrasive substances in heating, cooling, and air conditioning systems.

Features/Functions
Operating Modes
- Δp-c for constant differential pressure
- Δp-v for variable differential pressure
- PID control
- Controller mode (n=constant)

Manual Operation Level
- Setting differential pressure setpoint
- Setting speed (manual controller mode)
- Setting operating mode
- Pump ON/OFF
- Configuration of all operating parameters
- Fault reset

External Control Functions
- Control input "Priority Off"
- Control input "External pump switchover" (only effective in twin pump operation)
- Analog input 0–10 V, 0–20 mA for controller mode (DDC) and remote setpoint adjustment
- Analog input 2–10 V, 4–20 mA for controller mode (DDC) and remote setpoint adjustment
- Analog input 0–10 V for actual value signal of pressure sensor
- Analog input 2–10 V, 0–20 mA, 4–20 mA for actual value signal of pressure sensor

Signaling and Display Functions
