Dents on Liquid Filters




Dents on your filter may result in a cracked filter. These dents often come from an improper installation. Filters with dents should not be used, and filters dented after installation should be replaced as soon as possible. The cost of replacing a dented filter pales in comparison to the cost of any damages that could come out of a dented filter that fails while in use.

Stress on filters often results from pressure pulses in the system. Pressure is regulated by a pressure regulating valve. This valve is spring operated and intermittently opens and closes to regulate pressure. Once pressure goes beyond the setting of the spring in the regulating valve, the valve will open and allow the liquid to flow through until the pressure is alleviated and the spring can expand to close the valve. This process is repeated without pause while the system is in use, creating a pulsing effect. Filter canisters are subjected to the same pulsation. However, unlike the spring in the pressure regulating valve, canister material is susceptible to failure after such fatigue.

Filters are designed with a low carbon steel to resist fatigue and are formed so the stress created by the pulses in the system are equalized over the surface area of the canister. A dent provides an area of stress concentration where pressure pulses can greatly shorten the fatigue life of the canister.
