Pump diaphragms are critical sealing components widely used in diaphragm pumps and hydraulic accumulators. Made from high-performance elastomers such as NBR (nitrile rubber) and FKM (fluororubber), they offer excellent resistance to water, oil, abrasion, and corrosion, ensuring efficient and stable pump operation. Common models include the AR40, AR70, and D30, suitable for a variety of industrial and agricultural equipment.
