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 pipe installation or base mounting, featuring an integrated frequency converter for electronic control of, among others, 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
Suitable for pumping heating water (in accordance with VDI 2035), cold water, and water-glycol mixtures without abrasive particles, in heating, chilled water, and cooling systems.
