Double Diaphragm Pumps
Graco’s double diaphragm pumps are designed for chemical transfer applications. We offer air operated double diaphragm pumps and electric double diaphragm pumps, that come in many flow rates and sizes. Both metal and plastic housings can easily handle corrosive and abrasive fluids. All of our transfer pumps are thoroughly tested before they leave our factories.
Designed with fewer parts than competitive pumps, Graco’s air operated double diaphragm pumps features our stall-free, low pulsation air valve, which is externally accessible—ensuring rapid changeovers and minimum downtimes. Graco’s electric double diaphragm pumps (EODD) are ideal for applications that require low pulsation and a smooth flow. Our energy efficient electric drive reduces energy consumption up to 5x compared to traditional air operated diaphragm pumps. Each pump is ruggedly constructed to resist corrosion and deliver a long, trouble-free product life.
Customisable Fluid Sections
Easily customise your fluid selections with Graco’s chemical transfer pumps with housings that can handle all fluids, including corrosives and abrasives.
Multiple Power Sources
Depending on your manufacturing needs, Graco’s chemical double diaphragm pumps are available in both air and electric configurations. Each air operated double diaphragm pump and electric double diaphragm pump offers a similar range of features and benefits.
We design and build our double diaphragm pumps to hold in the harshest working environments. The best materials and the highest quality standards results in air operated double diaphragm pumps and electric double diaphragm pumps that are built to last.
Designed to meet the growing demand for clean energy and sustainable technologies, QUANTM is the world’s first (and only) affordable electric operated double diaphragm (EODD) pump built to minimise energy consumption by cutting energy usage and costs by up to 80%. Innovative, new FluxCore motors and...
Graco's ChemSafe pumps feature PTFE or UHMWPE (ultra high molecular weight polyethylene) corrosion-resistant fluid paths, which make them ideal for corrosive and abrasive chemicals. There's no exposed metals and they can be configured in various materials to meet most abrasion, temperature, and chem...
Graco’s Husky air operated diaphragm pumps feature corrosion-resistant fluid paths, which make them ideal for corrosive and abrasive chemicals and solvents. Husky diaphragm pumps can be configured to meet abrasion, temperature and chemical compatibility requirements. Also, they stall against pressur...
The Husky electric diaphragm pumps combine all of the benefits of a traditional air operated diaphragm pump, such as self-priming, stalling under pressure and increased diaphragm life with the benefits of an electric pump, such as energy cost savings, reduced pulsation and increased pump control.
