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

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

Dry-running twin pump in inline design for installation in pipelines or on a foundation, with an integrated frequency converter for electronic control, for maintaining constant or variable differential pressure (Δp-c/Δp-v), among other functions.

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

Application
Pumping of heating water (according to VDI 2035), cold water, and water-glycol mixtures without abrasive substances in heating, cold water, and cooling systems.

Features/Functions
Operating Modes

- Δp-c for constant differential pressure
- Δp-v for variable differential pressure
- PID control
- Setpoint operation (n=constant)

Manual Operation

- Setting the differential pressure setpoint
- Setting the speed (manual mode)
- Setting the operating mode
- Pump ON/OFF setting
- Configuration of all operating parameters
- Fault acknowledgment

External Control Functions

- Control input "Priority OFF"
- Control input "External pump changeover" (effective only in twin pump operation)
- Analog input 0-10 V, 0–20 mA for setpoint operation (DDC) and remote setpoint adjustment
- Analog input 2–10 V, 4–20 mA for setpoint operation (DDC) and remote setpoint adjustment
