Product Description
Hennvi’s VA series air operated double diaphragm pumps are highly efficient positive displacement pumps suitable for applications such as fluid transfer, tank emptying, and basic metering and filling. They are widely used in more than 20 industrial sectors, including chemicals, food and beverage, wastewater treatment, and electroplating.
The VA series diaphragm pumps are powered by compressed air and use the alternating reciprocating motion of dual diaphragms to draw in and discharge fluids. Since they do not require an electric motor, they fundamentally eliminate the risk of electrical sparks. Hennvi’s VA Series pumps have earned widespread recognition and been validated through long-term partnerships with users in various industrial sectors both domestically and internationally, thanks to their exceptional reliability, efficient air valve technology, and broad compatibility with a wide range of materials.
