Overview
Parker brand high-flow water filter cartridges are specially designed for high-flow filtration scenarios, adopting a 6-inch (152mm) or larger diameter structure. A single cartridge can achieve a flow rate of up to 110m³/h (40-inch specification), enabling efficient filtration through pleating technology and gradient pore size design. Their core advantages lie in high-flow processing capability (reducing cartridge quantity by over 50%), long service life (72-hour backwashing cycle), and high chemical resistance (resistant to strong acids, alkalis, and organic solvents), widely applied in water treatment, pharmaceuticals, food & beverage, and other industries. Compared with traditional cartridges, Parker high-flow cartridges can reduce equipment investment costs by 30%-50% under the same flow rate while decreasing maintenance frequency, especially suitable for high-flow scenarios such as RO reverse osmosis pretreatment and seawater desalination.
Core Technical Parameters and Structural Design
I. Key Technical Parameters
- Filtration Precision: Ranging from 0.1-100μm (melt-blown PP cartridges) to 0.45-70μm (glass fiber cartridges), meeting full-scenario needs from coarse to precision filtration.
- Materials: Filter media are made of polypropylene (PP) or glass fiber, with support layers and end caps constructed from glass fiber-reinforced PP. Sealing materials include EPDM, fluoroelastomer, etc., with a temperature resistance range of -20℃ to 80℃.
- Flow Characteristics: A single 40-inch cartridge delivers a water flux of 110m³/h, with a pressure drop ≤2.4Bar (recommended replacement threshold) and a maximum allowable pressure drop of 3.5Bar.
- Dimensions: Available in lengths of 508mm (20 inches), 1016mm (40 inches), and 1524mm (60 inches), with an outer diameter of 152mm or 170mm, compatible with standard high-flow filters.
II. Structural Innovations
1. Inside-out Flow Design: Fluid flows from the cartridge interior to the exterior, trapping impurities inside to avoid secondary contamination and simplifying replacement (no need to clean the filter housing).
2. Gradient Pore Size Technology: Pore sizes gradually increase from the inner to outer layers, forming a coarse-to-fine gradient structure that enhances dirt-holding capacity to 1-3kg/m², extending service life 2-3 times compared to ordinary cartridges.
3. Center Rod-Free Design: The cartridge employs an integral support structure, eliminating fluid short-circuiting caused by traditional center rods while enhancing compressive strength (withstanding 1.6MPa pressure).
Application Scenarios and Advantages
I. Typical Application Fields
1. Water Treatment Industry
- RO Reverse Osmosis Pretreatment: 5μm PP cartridges intercept colloids and particulate impurities, extending RO membrane life. A single 40-inch cartridge replaces 30 traditional 2.5-inch cartridges, reducing system volume by 50%.
- Seawater Desalination: A coastal desalination station uses Parker 5μm cartridges resistant to Cl⁻ concentrations >20,000ppm, with a 72-hour backwashing cycle (traditional PP cartridges last only 24 hours), cutting annual maintenance costs by 40%.
2. Pharmaceuticals & Biotechnology
- API Purification: 1μm glass fiber cartridges remove crystal impurities in cephalosporin antibiotics, increasing product purity from 98.5% to 99.8% and complying with GMP standards.
- Water for Injection Filtration: 0.22μm melt-blown PP cartridges combined with steam sterilization (121℃/30min) achieve >99.99% bacterial interception efficiency, meeting FDA certification requirements.
3. Food & Beverage Industry
- Beer Clarification: 0.45μm cartridges filter fermentation broth with turbidity <0.5NTU, eliminating the need for filter aids and yielding filtrate quality superior to traditional diatomite filtration.
- Edible Oil Degumming: 5μm cartridges remove phospholipid impurities, increasing oil yield by 2% while avoiding residue risks from chemical degumming.
4. Chemical & Petrochemical Sector
- Solvent Recovery: 316L stainless steel-reinforced cartridges filter organic solvents like dichloromethane, with a service life of 3 years (PP cartridges last only 6 months), saving over 2 million yuan in annual solvent costs.
- Catalyst Recovery: 10μm cartridges achieve a 99.5% recovery rate in polyethylene production, significantly reducing raw material loss.
II. Core Advantages
Parker high-flow cartridges excel in flow capacity, chemical resistance, dirt-holding capacity, service life, and environmental friendliness. A single 40-inch cartridge delivers 110m³/h, far exceeding the 3-5m³/h of traditional PP cartridges. Their resistance to strong acids, alkalis, and organic solvents outperforms traditional PP cartridges, with a dirt-holding capacity of 1-3kg/m² and a service life of 2-5 years (reusable with cleaning), reducing solid waste by 80%. Compared with stainless steel pleated cartridges, Parker cartridges offer lower costs and easier maintenance.
Selection and Maintenance Guidelines
I. Selection Recommendations
1. Precision Selection:
- Pretreatment (e.g., RO security filtration): 5-20μm;
- Precision filtration (e.g., electronic-grade water): 0.22-1μm;
- High-viscosity fluids (e.g., syrup): 10-100μm.
2. Material Matching:
- Acidic media: Prioritize PP material;
- High-temperature scenarios (>80℃): Customize metal-reinforced cartridges;
- Food & pharmaceutical applications: Use FDA-certified pure PP or glass fiber cartridges.
3. Interface Compatibility:
- Standard interfaces: 222, 226, M30;
- Special requirements: Customizable threaded or flange interfaces.
II. Maintenance Key Points
1. Backwashing:
- Perform at ≤0.2MPa pressure, combined with ultrasonic vibration to remove surface impurities, allowing 50-100 repeated uses.
2. Chemical Cleaning:
- Oily contamination: Circulate 10% sodium hydroxide solution for cleaning;
- Biological contamination: Soak in sodium hypochlorite solution (concentration ≤0.5%), avoiding reactions with PP material.
3. Monitoring & Replacement:
- Replace when pressure difference >2.4Bar or flow drops by 30%;
- Conduct integrity testing (e.g., bubble point test) quarterly.
Conclusion
Parker brand high-flow water filter cartridges have become benchmark products in industrial filtration due to their high flow, long life, and resistance to extreme conditions. Their core value lies in addressing the efficiency and cost challenges of traditional cartridges in high-flow scenarios through structural innovations (e.g., gradient pore size, center rod-free design) and material optimization (medical-grade PP/glass fiber). With stricter environmental regulations and industrial automation upgrades, the reusability and intelligent monitoring functions (e.g., integrated pressure difference sensors) of Parker cartridges will further expand their application scope. In the future, combined with nanocoating technologies (e.g., superhydrophobic surfaces) and AI predictive maintenance systems, Parker high-flow cartridges are expected to achieve more precise filtration control in high-value fields such as semiconductors and new energy, driving the industry toward efficiency and sustainability.
