Versamatic Air-Operated
Double-Diaphragm Pumps

For more than 30 years, Versamatic has been at the forefront of advancing air-operated double-diaphragm pump technology. Each Versamatic positive displacement diaphragm pump features two diaphragms that operate under balanced pressure to move fluid while minimizing wear.

Frequently Asked Questions

Yes, Chamco provides comprehensive installation services for diaphragm pumps. Tailoring the process to meet your specific operational requirements, our team handles the setup to deliver optimal performance. That includes expert guidance, seamless integration with your existing systems, and post-installation support to maximize efficiency and longevity on track.

A self-priming pump can evacuate air from the pump chamber and initiate fluid flow without external assistance. This capability matters most in suction-lift applications such as emptying a tank or pit, where you’d otherwise need to prime the pump by hand or add separate priming equipment. Because self-priming pumps tolerate some air or gas in the fluid, they can continue running under conditions that would interrupt other pump types, improving operational efficiency and simplifying maintenance.

Yes. AODD pumps are available in stainless steel, metal, and plastic, so you can match the pump’s construction to your fluid and avoid premature corrosion. This makes them suitable for challenging chemical or slurry applications.

Yes, Chamco’s comprehensive maintenance services for diaphragm pumps cover part replacements, routine inspections, and troubleshooting. Our 24/7 service support ensures minimal downtime, and our team of factory-trained technicians can handle repairs for any air-operated double diaphragm pump throughout its lifecycle.

Air-operated diaphragm pumps run on compressed air, using an air valve to move the diaphragms back and forth. Electric diaphragm pumps use a motor to drive the diaphragm instead. AODD pumps are often the better choice in wash-down areas, hazardous locations, or anywhere a spark from electrical equipment is a safety concern, since they have no electrical components in the pump itself.

Pump size depends on your required flow rate, the fluid’s viscosity and solids content, and your suction and discharge port requirements. Chamco’s team reviews your application details, including flow rate targets and line size, to recommend the right industrial diaphragm pump from the Versamatic lineup.

Yes. Versamatic AODD pumps are compatible with hydraulic fluid when fitted with the correct diaphragm and seal material for that fluid’s chemical makeup. Talk to Chamco’s team about your specific hydraulic fluid before ordering to confirm the right elastomer and wetted-part combination.

We take pride in partnering with leading pump manufacturers, such as Versamatic, to ensure the highest quality and reliability in every engineered system we deliver. Chamco also works with other trusted manufacturers for engineered pump and compressor systems, including Sullair, Vanair, Omega, Peerless, Cornell, and Grundfos.
