Replace Pall Ultipleat – Drop-in Aftermarket High Flow Filter Cartridge for Industrial Liquid Filtration

Replace Pall Ultipleat aftermarket filter cartridges are fully interchangeable substitutes for genuine Pall Ultipleat HFU series high flow filter elements. Designed with core-free crescent pleated gradient media, matched dimensional specifications, single open-end structure and inside-out flow path, these replacement cartridges fit standard Pall Ultipleat filter housings without equipment modification. Featuring stable absolute filtration efficiency, outstanding dirt holding capacity and competitive cost advantages, they serve as ideal spare parts for RO security filtration, desalination, power plant water treatment and petrochemical projects. Numerous industrial system integrators adopt HFU660GF060H13 glass fiber filter cartridge and HFU640UY045H replacement element together with Replace Pall Ultipleat filters to construct multi-stage pretreatment systems and effectively protect downstream membrane modules.

Product Introduction

Replace Pall Ultipleat filter cartridges are engineered as economical drop-in alternatives to the well-known Pall Ultipleat HFU high flow series. Original Ultipleat filters are widely applied in large-scale industrial liquid purification worldwide. Nevertheless, high purchase price and unpredictable long lead times bring heavy operational pressure to EPC contractors and end plant operators. Our aftermarket replacement series solves these procurement pain points while meeting equivalent industrial filtration standards.

The product range covers mainstream HFU models including HFU620, HFU640 and HFU660, with available lengths of 20”, 40” and 60”. Filtration ratings span 1μm ~ 50μm, supporting both nominal and absolute precision requirements. Two mainstream media options are available: gradient polypropylene pleated media and high-efficiency glass fiber media. All cartridges adopt glue-free thermal fusion technology to eliminate adhesive contamination and fiber shedding. Sealing options including EPDM, Buna-N and Viton are offered to adapt to aqueous media, weak chemicals and varying operating temperatures. The maximum continuous working temperature reaches 82°C, with a maximum allowable differential pressure of 3.4 bar, suitable for 24-hour continuous heavy-duty industrial operation.

Every finished product undergoes strict dimensional inspection, bubble point efficiency testing and pressure tightness test to guarantee reliable interchangeability. It efficiently removes suspended solids, pipeline rust, sediment and fine colloids, preventing membrane fouling and abrasion of downstream pumps and precision valves.

Filtration Principle

Replace Pall Ultipleat retains the classic inside-out filtration principle of original Ultipleat design. Driven by system pressure, raw fluid enters the inner cavity of the core-free filter cartridge and permeates outward through multi-layer gradient pleated media. Large particles and flocs are trapped on inner coarse layers, while micro-particles and colloids are deeply intercepted by outer precision media.

Contaminants remain enclosed inside the cartridge during replacement, avoiding secondary particle leakage into clean fluid pipelines. Optimized crescent pleat layout reduces fluid dead zones and maintains low initial differential pressure. Purified fluid flows outward and enters subsequent RO, UF and other separation equipment. Operators shall replace cartridges promptly once inlet-outlet differential pressure reaches 25–35 PSID to restore the designed flow rate and filtration performance.

Core Competitive Strengths

• Full Drop-in Interchangeability:

• Dimensions, end cap geometry, lifting handle and O-ring positions benchmark original Pall Ultipleat standards; no housing modification required to reduce maintenance downtime.

• Optional Dual Filter Media:

• PP media for general water pretreatment; glass fiber media for high-precision particle removal and strict membrane protection demands.

• High Dirt Holding Capacity:

• Optimized pleat structure slows differential pressure rise and extends service cycle, lowering overall consumable expenditure.

• Cost-Effective Aftermarket Solution:

• Far lower cost than genuine Pall filters, with flexible MOQ and faster delivery schedule.

• Complete Quality Assurance:

• Batch testing ensures consistent filtration efficiency for long-term engineering projects.
