Ultra long diaphragm life: GRACO pneumatic diaphragm pumps have excellent diaphragm performance, with a service life that is 1/3-1/2 longer than similar products from other manufacturers. Some models of diaphragms even have a service life of over 30 million times, greatly reducing equipment maintenance frequency and lowering usage costs.
Strong self-priming ability: With excellent self-priming performance, the large suction range can reach 7M, without the need for additional water injection and diversion operations. It can start quickly and quickly suck liquid into the pump chamber for delivery, especially suitable for work scenarios that require frequent start stop, effectively improving work efficiency.
Reliable corrosion resistance: Multiple material options are available for parts in contact with liquids, including 316L stainless steel, aluminum alloy, polypropylene, conductive polypropylene, and polyvinylidene fluoride. The surface of the metal aluminum alloy material is treated with anodizing, and the pressure chamber is coated with epoxy coating after anodizing. The central shaft is made of stainless steel material, which makes the pump body highly corrosion-resistant and capable of stable operation in harsh environments.
Lubrication free air pressure chamber: Adopting an oil-free air pressure chamber design, it can be lubricated free when using CDA driven gas. The air pressure chamber has fewer parts, a simple structure, and low dependence on seals. No lubrication additives need to be added, reducing maintenance work and avoiding possible failures caused by lubrication problems.
Stable operating performance: It can operate stably in low and high pressure environments, as well as in slow and fast operating states, without any jamming. Using patented air valves with high wear resistance and a unique three-way pilot valve reversing design, the pump ensures extremely high reliability in various application scenarios, achieving zero failure rate and ensuring production continuity.
Convenient maintenance: All components can be replaced without opening the liquid chamber, the parts are easy to assemble, and the whole machine is easy to repair. The air chamber is located above, making it difficult for liquids to enter and enabling online maintenance, greatly reducing equipment downtime and improving equipment efficiency.
