Frequently Asked Questions

What is an Air Operated Diaphragm Pump?

An AODD pump uses compressed air to alternately pressurize two diaphragms, creating suction and discharge cycles. It’s self-priming, can run dry, and handles viscous, abrasive, and shear-sensitive fluids.

Can your pumps handle abrasive slurries?

Yes. Our AOK and AOE series pumps are designed with wear-resistant materials and robust diaphragms to handle abrasive media like mining slurries and wastewater sludge.

Are your pumps ATEX certified?

Many of our models are ATEX rated for use in explosive atmospheres, making them safe for chemical, petrochemical, and pharmaceutical applications.

Do you offer custom configurations?

Yes. We provide customization for materials, port sizes, diaphragm types, and accessories to meet specific application requirements.

What is the warranty on your pumps?

We offer a standard 12-month warranty on all pumps, covering defects in materials and workmanship under normal operating conditions.
