A pump diaphragm is a critical flexible component typically constructed from elastomers like NBR (Nitrile Butadiene Rubber) or FKM (Fluorocarbon Rubber), or thermoplastic materials. Installed within hydraulic/pneumatic accumulators or pump cavities, it acts as a dynamic barrier that isolates fluids while responding to pressure fluctuations. Its primary role is to deform under pressure changes, enabling energy storage and release cycles. This functionality enhances system efficiency by dampening pulsations, reducing wear, and maintaining consistent flow rates. Diaphragms are widely used in industries requiring precise fluid handling, such as chemical processing, water treatment, and oil/gas applications. Their design must balance flexibility with durability to withstand repetitive motion and varying pressures.
Common models include AR40, AR70, and D30, suitable for various industrial and agricultural equipment. The current dimensions
