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

Dry-rotor twin pump in inline design for pipe installation or base mounting with integrated frequency converter for electronic control for, among others, constant or variable differential pressure (Δp-c/Δp-v).

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