Stainless steel precision security filter accessories, filter element spring pressure cap plug

PP filter spring cap is one of the commonly used accessories in water treatment and liquid filtration systems. Its main function is to fix and seal PP (polypropylene) filter cartridges to ensure the stability and effectiveness of the filtration process. Here are some detailed information about the PP filter spring cap:

Material characteristics:

• 304 stainless steel materialThis type of pressure cap is usually made of 304 stainless steel because this material has good corrosion resistance and high temperature resistance, making it suitable for use in various working conditions including chemical and high-temperature liquid treatment.

Structure and Function:

• Spring designThe spring cap may contain spring elements inside, which provide uniform pressure to the filter element, ensuring a tight installation, reducing bypass flow, and improving filtration efficiency.

• Fixed and sealedThe pressure cap is connected to the filter housing through threads, clips, or other mechanisms to ensure that the filter element is securely in place and to prevent unfiltered liquid from bypassing the filter element through a sealed design.

• Double hat designSome models may adopt a double cap design, where the upper and lower pressure caps work together on the filter element to further enhance the fixing effect and sealing.

Application fields:

• Widely used in the water treatment industry, including drinking water treatment, RO reverse osmosis pretreatment, security filtration, industrial water treatment, etc.

• It is also applicable to filtration systems in industries such as chemical, pharmaceutical, food and beverage, electronics, etc. that have strict requirements for water quality.

When selecting the appropriate PP filter spring cap, factors such as filter size, specific requirements of the filtration system, and working environment need to be considered to ensure filtration efficiency and system compatibility.
