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 foundations, equipped with an integrated frequency converter for electronic control, e.g. for constant or variable differential pressure (Δp-c/Δp-v).

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

Application
Pumping of heating water (according to VDI 2035), cold water, and water-glycol mixtures without abrasive substances in heating, chilled 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 Level
- Setting the differential pressure setpoint
- Setting the rotational speed (manual mode)
- Setting the operating mode
- Switching pump ON/OFF
- Configuration of all operating parameters
- Error acknowledgement
External Control Functions
- Control input “Priority OFF”
- Control input “External Pump Changeover” (active only during 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
- 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
Indication and Reporting Functions
- Collective fault signal (SSM)
- Collective run 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 integration into building automation
Safety Functions
- Full motor protection with integrated trip electronics
- Access lock
Twin Pump Management (Twin or 2x Single pump)
- Duty/standby operation (automatic switchover in case of fault)
- Duty/standby operation with pump changeover every 24 hours
- Parallel operation
- Parallel operation (efficiency-optimized peak load cut-in/cut-out)

Your benefits
- Energy savings due to integrated electronic performance adaptation
- Easy operation via Green Button Technology and display
- Multiple operating modes: duty/standby and parallel operation
- Configurable error behavior tailored for heating and climate applications
- Integrated full motor protection (KLF) with tripping electronics
