XH220 High-Pressure | Metal AODD Pumps

Wilden 25 mm (1") High-Pressure Threaded Bolted Metal AODD Pump - H220 (ATEX Certified)

Description
The Wilden 25 mm (1") High-Pressure Threaded Bolted Metal AODD Pump (H220) is an ATEX-certified, high-pressure solution for demanding industrial applications, featuring a specialty Air Distribution System (ADS) with Duplex technology and a double-acting power piston. This Air-Operated Double-Diaphragm (AODD) pump delivers discharge pressures up to 20.7 bar (300 psi), making it ideal for high-pressure duties like filtration and chemical sludge transfer. Its ATEX certification ensures safe operation in hazardous environments, while its bolted metal construction provides robust durability for handling viscous, solid-laden slurries.
