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

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

Design
Electronically controlled dry-running twin pump in inline design with flanged connections and automatic performance 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
- Set point operation (n=constant)

Manual Operation Level
- Setting of differential pressure setpoint
- Setting speed (manual set point operation)
- Selection of operating mode
- Pump ON/OFF
- Configuration of all operating parameters
- Fault acknowledgement

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 set point operation (DDC) and remote setpoint adjustment
- Analog input 2–10 V, 4–20 mA for set point operation (DDC) and remote setpoint adjustment
- Analog input 0–10 V for actual value signal from pressure sensor
- Analog input 2–10 V, 0–20 mA, 4–20 mA for actual value signal from pressure sensor

Alarm and Indication Functions
- Collective fault signal (SSM)
- Collective running signal (SBM)

Data Exchange
- Infrared interface for wireless data exchange with IR monitor/IR stick
- Slot for Wilo IF modules (Modbus, BACnet, CAN, PLR, LON) for building automation integration

Protection Functions
- Full motor protection with integrated electronic trip
- Access lock
- Twin pump management (twin or two single pumps)
- Duty/standby operation (automatic fault changeover)
- Duty/standby pump changeover every 24 hours
- Parallel operation
- Addition mode (energy-efficient peak load activation/deactivation)
