Air-Operated Double Diaphragm Pump for Aggressive, High-Viscosity Fluids and Liquids With Suspended Solids

Engineered for total reliability in critical processes, GemmeCotti HAOD air-operated double diaphragm (AODD) pumps provide a dependable solution for demanding fluid transfer applications. They are specifically designed to handle difficult media, including aggressive chemicals, highly viscous liquids, and fluids containing suspended solids.

Each AODD pump features an advanced anti-stalling pneumatic circuit that ensures continuous and efficient operation without the need for lubricated air. This robust design delivers high operational reliability, allowing the pumps to run dry for extended periods without damage and to operate safely against a closed discharge, thereby protecting the entire system.

To ensure full chemical compatibility, the HAOD series is available in a wide range of materials, including polypropylene, PVDF, and AISI 316 stainless steel. In addition, intrinsic safety is ensured through the availability of certified ATEX versions, making these pumps suitable for use in potentially explosive atmospheres.

A solution for every industrial challenge

The HAOD series is designed for maximum versatility, offering a robust and efficient solution for a wide range of industries and applications. The product range covers diverse performance requirements, from small models for precise dosing applications to larger units for bulk transfer, with maximum flow rates of up to 310 L/min.

Whether used in the chemical, pharmaceutical, or water treatment sectors, HAOD pumps integrate seamlessly into existing processes, delivering consistent, reliable performance.
