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 suitable for installation in pipelines or mounting on a foundation with 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 flanged connection and automatic power adjustment.

Application
For pumping heating water (per VDI 2035), cold water, and water-glycol mixtures without abrasive substances in heating, chilled water, and cooling systems.

Features/Functions
