Ptfe-lined Basket Filter Design Features And Applications

For food and beverage lines, install a PTFE lined basket strainer with flange connections (PN10, PN16, or 150LBS) to remove solid contaminants and prevent corrosion. The thick PTFE lining isolates fluid from the metal body, resisting acidic products and CIP chemicals. Available in sizes DN25–DN300, pressure up to 10 bar, temperature -29°C to +180°C. Internal surfaces polished to Ra ≤ 0.8 µm meet FDA standards.

The Contamination and Corrosion Challenge

Food lines carry particulates that damage pumps, valves, and nozzles. Metal strainers corrode from acidic fruit juices, tomato products, and aggressive CIP agents. A ptfe strainer provides an inert barrier that resists corrosion while capturing contaminants. The PTFE lined pipe system protects the entire filtration path.

Contaminants removed:

• 🔬 Raw ingredient particles

• ⚙️ Equipment wear debris

• 🧪 Pipe scale and rust

• 🧼 Product residues

• ✅ Foreign materials

PTFE Lining Material Properties

PTFE resists acids, bases, and solvents from -29°C to +180°C. Compression‑molded onto the body and basket, the lining creates a seamless, pore‑free barrier. This ptfe strainer handles acidic fruit juices, dairy products, and CIP chemicals without degradation. The non‑stick surface prevents product adhesion and simplifies cleaning. The PTFE lined pipe in the system ensures complete corrosion protection.

Construction and Design Features

The PTFE lined basket strainer has a metal body with thick PTFE lining, a removable PTFE‑lined basket, and a cover with quick‑opening clamps or bolts. Flanged connections, sizes DN25–DN300. The basket captures particles down to 0.5 mm, with mesh options 20‑200 mesh. Cover allows quick basket access without breaking pipe joints. This PTFE lined strainer supports CIP cleaning.

Key design features:

1. Thick PTFE lining (2‑3 mm) resists erosion and permeation

2. Removable PTFE‑lined basket for easy cleaning

3. Flanged connections for secure installation

4. Quick‑opening cover for basket access

5. Self‑draining design for complete product evacuation

Specifications and Selection Criteria

Applications and Selection Considerations

Install in fruit juice lines, dairy processing, syrup and sauce transfer, CIP supply headers, and beverage filling systems. The ptfe strainer is specified where corrosion resistance and product purity are required.

When selecting:

• Size — DN25–DN300 based on line diameter.

• Mesh — 20‑200 mesh based on particle removal needs.

• Temperature — PTFE handles -29°C to +180°C.

• Pressure — PN10, PN16, or 150LBS.

The PTFE lined pipe system protects all wetted surfaces. The strainer supports CIP and SIP without disassembly.

Installation and Maintenance

Install between flanges per ANSI or EN standards. Use PTFE gaskets matched to the process media. Open the cover, remove the basket, clean or replace it, and reinstall — without breaking pipe joints. Replace basket seals every 12‑18 months.

This strainer removes contaminants while protecting product purity and equipment integrity. The PTFE lined basket strainer delivers reliable, corrosion‑free filtration.

FVF PTFE Lined Basket Strainer

• FVF lined strainer is the corrosion resistant equipment that used in a variety of corrosive services for the removal of debris from the pipeline or solid particles from the media.
• The unique design allows the strainer to be easily removed for cleaning or replacement. Impurity substance stops at PTFE screen so that the purity flow can go through the strainer. After a period of time, take out the dismountable filter screen tub, and it can be reassembled after cleaning.Therefore it is easy maintenance.
• Screen size of the lined strainer ranges from 16 to 100 meshes and 16 meshes as standard.
• By far the lined strainer is widely used in petroleum, chemical pharmaceutical and environmental protection industries. It can not only enlarge the lifespan of pump and other equipment, but also ensure the safety of the complete system. Lined strainer becomes the indispensable equipment for industrial production.
