VA
The VA series pneumatic double diaphragm pump is a robust, versatile fluid transfer solution engineered for demanding industrial applications involving abrasive slurries, corrosive chemicals, and viscous liquids. As a leading slurry transfer diaphragm pump designed for industrial operators, this air-operated unit eliminates the risk of shaft seal leakage, a common pain point in centrifugal and gear pumps, ensuring safe and contamination-free fluid handling. Available in 8 standard port sizes ranging from 1/4× to 3×, the pump accommodates flow rates from 1.0 L/min to 1000 L/min, making it suitable for both small-scale dosing and large-volume bulk transfer operations. Its modular design allows for quick material swaps to match specific fluid properties, providing unmatched flexibility for diverse industrial processes.
Unlike traditional pumps with rotating shafts, our chemical resistant air operated diaphragm pump features a sealless construction that completely prevents fluid leakage. This critical feature protects workers from hazardous chemical exposure, eliminates environmental contamination risks, and reduces costly cleanup and downtime associated with seal failures.
We offer an extensive range of wetted materials to handle virtually any fluid type. Body materials include acetal, polypropylene, aluminum, Kynar (PVDF), SUS 316 stainless steel, and cast iron, while diaphragms, ball valves, and seats are available in Teflon, Viton, Santoprene, and Hytrel. This versatility makes the pump ideal for corrosion resistant diaphragm pump applications involving strong acids, alkalis, solvents, and abrasive slurries.
The pump delivers reliable self-priming performance up to 5 meters, eliminating the need for priming tanks or manual priming before operation. It can also run dry indefinitely without damage, a critical safety feature for processes where fluid supply may be interrupted unexpectedly.
With only a few moving parts and no complex seals or bearings in the fluid path, the industrial slurry pump requires minimal maintenance. Parts can be replaced quickly on-site without special tools, reducing downtime and lowering total ownership costs.
Powered by compressed air, the pump is inherently explosion-proof and certified for use in hazardous environments where flammable gases or vapors are present, meeting global safety standards.
