Diaphragm Pumps

Chamco proudly distributes Versamatic air-operated double diaphragm (AODD) pumps, known across the industry for raising the bar on performance and versatility.

A Robust Pumping Solution for
Low-Pressure Applications

Air-operated double diaphragm pumps offer numerous advantages for a wide variety of low-pressure transfer applications including everything from the transfer of clear liquids like water to highly solid-laden liquids like wastewater. These pumps are self-priming and can operate dry with no hydraulic fluid. Unlike electric diaphragm pumps, AODD pumps are powered only by compressed air, which is ideal for applications without electricity.

Industrial Diaphragm Pumps

At Chamco, we are committed to only supplying industrial diaphragm pump products that are on the leading edge of technology with a proven track record of:

  • Durability
  • Reliability
  • Performance

Versamatic Air-Operated
Double-Diaphragm Pumps

For over 30 years, Versamatic has been refining and advancing its air-operated double-diaphragm pump collection. Each Versamatic positive displacement pump features two diaphragms, resulting in less wear due to pressure balancing between each diaphragm.

Versamatic AODD pumps come in a variety of flow rates and sizes depending on your pumping requirements, with many of the pumps offered in different materials, including bolted and clamped aluminum or stainless steel and bolted plastic.
