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

Dry-Running Twin Pump in inline design for pipe installation or mounting on a foundation, equipped with an integrated frequency converter for electronic control—offering, among others, constant or variable differential pressure regulation (Δp-c/Δp-v).

Design:
Electronically controlled dry-run twin pump in inline version with flanged connection and automatic power adjustment.

Application:
Circulation of heating water (as per VDI 2035), cold water, and water-glycol mixtures without abrasive substances in heating, chilled water, and cooling systems.

Equipment/Features:
