0904.009 model NBR Buna Rubber membrane Diaphragm Pump

The pump diaphragm is a crucial sealing component widely used in diaphragm pumps and hydraulic accumulators. Made from high-performance elastomer materials such as NBR (Nitrile Rubber) and FKM (Fluorocarbon Rubber), it offers excellent oil resistance, wear resistance, and corrosion resistance, ensuring efficient and stable pump operation. Common models include AR40, AR70, and D30, suitable for various industrial and agricultural equipment.
