The material selection for oil seals is crucial as it determines their performance, durability, and compatibility with various fluids. Common materials used in oil seals include nitrile rubber, fluoroelastomers, silicone rubber, and polytetrafluoroethylene (PTFE). Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range Nitrile rubber is widely used due to its good chemical resistance, oil resistance, and moderate temperature range

When the supply water strikes the valve, it creates a sudden pressure surge that forces the ram closed, trapping the water. As the pressure subsides, the ram opens, allowing the trapped water to escape through the delivery valve, propelling water up the delivery pipe. Simultaneously, the suction valve opens, allowing new water to enter and the cycle repeats Simultaneously, the suction valve opens, allowing new water to enter and the cycle repeats
