Product Description:

Ultra long diaphragm life:
GRACO pneumatic diaphragm pumps boast exceptional diaphragm performance, with a service life that is 1/3-1/2 longer than similar products from other manufacturers. Some diaphragm models even offer a service life of over 30 million cycles, significantly reducing the frequency of equipment maintenance and cutting down on usage costs.

Strong self-priming ability:
Featuring outstanding self-priming performance, these pumps offer a wide suction range of up to 7 meters without the need for additional water injection or diversion operations. They can start quickly, sucking liquid into the pump chamber for delivery promptly, making them especially suitable for scenarios requiring frequent start-stop cycles and effectively enhancing work efficiency.

Reliable corrosion resistance:
Several material options are available for parts in contact with liquids, such as 316L stainless steel, aluminum alloy, polypropylene, conductive polypropylene, and polyvinylidene fluoride. The metal aluminum alloy surface undergoes anodizing treatment, with the pressure chamber receiving an epoxy coating post-anodizing. The stainless steel central shaft enhances the pump body's corrosion resistance, enabling stable operation in challenging environments.

Lubrication free air pressure chamber:
By utilizing an oil-free air pressure chamber design, lubrication is unnecessary when using CDA as the driving gas. With fewer parts, a simple structure, and low reliance on seals, the air pressure chamber reduces maintenance needs and eliminates potential failures due to lubrication issues.

Stable operating performance:
These pumps can operate reliably in both low and high pressure settings, as well as at various operating speeds without jamming. The pumps feature patented air valves with high wear resistance and a unique three-way pilot valve reversing design, ensuring exceptional reliability across different applications and achieving a zero failure rate, thereby ensuring continuous production.

Convenient maintenance:
All components are replaceable without opening the liquid chamber, simplifying assembly and repair processes. The air chamber positioned above prevents liquid entry, enabling online maintenance and significantly reducing equipment downtime while enhancing equipment efficiency.

Technical Parameters:

GRACO pneumatic diaphragm pumps are available in a variety of specifications and models, featuring diameters ranging from 1/4", 3/8", 1/2", 3/4", 1", 1 1/2", 2", to 3", to cater to diverse flow requirements.

The flow range of these pumps extends from 1.1m³/h to 62m³/h, with a maximum working pressure of 120PSI (8.4BAR) and a typical operating pressure between 0.14-0.84Mpa, enabling them to meet the pressure demands of various working conditions.

There are various options for membrane materials such as Teflon, Santoprene/Neoplast, Buan N, etc. Users have the flexibility to choose suitable combinations based on the characteristics of the conveying medium.

Applications:

GRACO pneumatic diaphragm pumps are suitable for various industrial fields, including:

• Chemical industry: used for treating corrosive liquids such as acids, bases, solvents, suspended solids, and dispersed systems
• Petrochemical industry: suitable for crude oil, heavy oil, immature oil, mud, sludge, etc
• Coatings industry: used for resins, solvents, colorants, paints, etc
• Daily chemical industry: processing detergent, shampoo, lotion, etc
• Environmental protection, wastewater treatment, construction, sewage, fine chemicals: suitable for various special occasions, pumping media that cannot be pumped by conventional pumps

GRACO pneumatic diaphragm pumps come in a variety of material options, including engineering plastics, aluminum alloys, cast iron, and stainless steel. According to different liquid media, the pump body adopts different sealing materials, such as rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, etc., to meet the needs of different users.

These materials enable the pump to operate stably for a long time in various corrosive environments.
