​Wilo Atmos GIGA-I, 65/250-30/2, Circulation Pump

Description

Single-stage centrifugal pump with dry motor with Inline design for pipe installation or placement on a base plate. Vibration and noise dampened block construction with lantern and standard flange motor (norm motor) with fixed coupling. With pleated mechanical shaft seal with forced circulation, independent of direction of rotation (from 37 kW/4-pole and with a mechanical cartridge seal in the replacement coupling system as an option for changing the mechanical seal without disassembling the motor) and cavitation-reducing impeller. Flange with pressure measurement connections R 1/8.
