Features and Advantages

1. High Flow Capacity, Reduced Costs

• Fewer Cartridges Needed: High flow rates (up to 70 m³/h for 60" models) minimize the number of cartridges required, lowering initial investment and labor costs.

• Compact Housing Compatibility: Smaller filter housings reduce capital expenditure and footprint.

2. Robust Construction for Longevity

• Reinforced PP Framework: Enhances structural integrity under high pressure (up to 5 bar).

• Thermally Bonded Media: Prevents particle bleed-through and media migration, common in wound cartridges.

3. Versatile Media Options

• Polypropylene or Cellulose Media: Suitable for both aqueous and non-aqueous fluids, ensuring broad compatibility.

• Pleated Design: Increases surface area, reducing pressure drop by 30% and extending service life.

4. User-Friendly Design

• Built-in Handle: Simplifies cartridge replacement, improving safety and efficiency.

• Ultrasonic Welding: Ensures leak-free interfaces without chemical adhesives.

Product Structure

The Lifilter PK Series employs a multi-layered architecture for optimal performance:

1. Outer Protective Layer: Nylon mesh for coarse particle pre-filtration.

2. Primary Filtration Layer:

• Composite Membrane: Combines a domestic引流 layer (flow distribution) with high-precision media for multi-stage filtration.

3. Inner Support:

• PP-Reinforced Skeleton: Provides mechanical strength and maintains shape under pressure.

4. Sealing System:

• EPDM/Viton Seals: Resistant to high temperatures and aggressive chemicals.

• Ultrasonically Welded End Caps: Eliminate adhesive contamination risks.

Working Principle

The filter operates through a graded filtration mechanism:

1. Pre-Filtration: Fluid enters through the nylon outer mesh, trapping large particulates (>100 μm).

2. Flow Distribution: The引流 layer ensures even fluid distribution across the pleated media.

3. Depth Filtration: Composite membranes capture particles down to 1 μm, leveraging both surface and depth retention.

4. Final Purification: Submicron particles are retained by the precision membrane, ensuring clean output.

5. Pressure Management: Low-pressure drop design maintains system efficiency even at high flow rates.

Applications in the Petrochemical Industry

Key Use Cases

• Lubricating Oil Filtration: Removes metal shavings, sludge, and wear debris to protect turbines and compressors.

• Fuel Purification: Ensures clean fuel supply for boilers and engines, preventing injector clogging.

• Catalyst Recovery: Captures valuable catalyst particles (efficiency >99%) in refining processes.

• Acid Gas Scrubbing: Compatible with H₂S and CO₂-laden streams due to chemical-resistant seals.

Case Study

A petrochemical plant replaced standard cartridges with Lifilter PK Series, achieving:

• 50% longer service intervals (from 30 to 45 days).

• 20% reduction in maintenance costs due to fewer replacements.

Applications in Other Industries

1. Water Treatment

• Reverse Osmosis (RO) Pre-Filtration: Protects membranes from fouling by sediments and organic matter.

• Wastewater Recycling: Removes heavy metals (e.g., lead, arsenic) and suspended solids to meet discharge standards.

2. Food & Beverage

• Edible Oil Clarification: Eliminates phospholipids and gums, extending shelf life.

• Brewery Filtration: Ensures yeast-free outputs for consistent product quality.

3. Pharmaceuticals

• WFI (Water for Injection) Systems: Maintains USP/EP compliance by filtering endotoxins and particulates.

• Bioreactor Media Sterilization: Removes microbial contaminants from fermentation broths.

4. Power Generation
