Parker MFNP050‑40N‑ITT for Ultrafiltration Pretreatment Protection
Parker MFNP050‑40N‑ITTis a vital pretreatment component for industrial ultrafiltration systems. This liquid filter provides high dirt‑holding capacity and reduces the frequency of cartridge replacement. Constructed from robust pleated polypropylene material, it fits standard large‑flow filter housings and can cooperate with High‑flow water filter cartridge and Water Filtration PP Pleated Filter to establish complete multi‑stage water‑treatment workflows. It is widely applied in power, chemical, food‑beverage process water purification projects across global markets.
Parker MFNP050‑40N‑ITT is a large‑diameter high‑flow pleated filter cartridge specially developed for ultrafiltration front‑end protection. As a reliable interchange‑grade industrial filter element, it is installed upstream of ultrafiltration membrane modules. Its core function is to trap suspended solids, colloids, fine sediment, pipeline rust and granular contaminants in raw water. By removing most particulate impurities ahead of time, it effectively alleviates UF membrane fouling risk, cuts down chemical cleaning times and extends the service life of expensive ultrafiltration membrane components.
Different from conventional small‑size filter cartridges, MFNP050‑40N‑ITT adopts large‑diameter pleated structural design, which greatly expands the effective filtration area of single cartridge. Under equivalent operating flow conditions, fewer filter elements are required inside filter housing. For system integrators and end‑users, it brings practical benefits: fewer filter housings, less installation workload and lower long‑term operation‑maintenance costs. When configuring the whole water‑treatment skid, users can match it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to realize multi‑grade gradient pre‑filtration interception effect.
The whole filter cartridge adopts all‑polypropylene construction. Thermal‑bond pleating craft replaces glue bonding, eliminating secondary pollution risk caused by adhesive dissolution under long‑time water scouring. End caps and inner‑outer support skeletons are integrally molded, maintaining stable structural performance under continuous high‑flow impact and frequent pressure fluctuation. Whether for newly‑built ultrafiltration water‑making equipment or spare‑part update of existing water‑treatment production lines, Parker MFNP050‑40N‑ITT can deliver stable and consistent pretreatment filtering performance.
Parker MFNP050‑40N‑ITT follows surface‑depth composite pleated filtration principle. After raw water flows into filter housing, fluid passes radially inward from the outer surface of filter cartridge. Large solid particles are first intercepted on outer pleated surface, while tiny fine impurities penetrate into polypropylene fiber layers and get trapped inside dense fiber gaps.
Benefiting from large‑area pleated layout, pollutants are evenly distributed over the whole filter medium instead of accumulating only on partial surface. This design slows down differential‑pressure rising speed, maximizes dirt‑holding capacity and prolongs the service cycle of filter cartridge. When inlet‑outlet pressure difference reaches preset threshold value, it indicates filter medium is saturated with intercepted pollutants, and operators need to replace the whole cartridge.
It acts as the front‑line protective barrier for ultrafiltration equipment. Without this pretreatment protection, raw water carrying particles will directly flow onto UF membrane surface. Solid contaminants will deposit on membrane surface, block membrane pores, accelerate membrane fouling, increase chemical cleaning frequency and may even trigger irreversible membrane damage. When used in series with PFTM11UNF high flow filter cartridge for multi‑stage combined filtration, overall stability of water‑treatment system can be further improved. It should be noted that this cartridge only removes solid particulate contaminants and cannot get rid of dissolved ions in water, so it only undertakes pretreatment work before ultrafiltration membranes.

Every batch of Parker MFNP050‑40N‑ITT undergoes complete production‑process inspection and finished‑product testing before delivery. Incoming material inspection is carried out for polypropylene filter cloth, support skeletons and end‑cap raw materials to guarantee raw‑material consistency. During production process, sampling inspection covers pleating amplitude, thermal‑bond strength and end‑cap sealing performance.
Finished‑product tests contain bubble‑point integrity test, cyclic pressure impulse test and water‑flow pressure‑drop detection. Defective products with medium cracks, poor sealing or structural looseness will be fully eliminated. Glue‑free thermal‑bond process avoids adhesive dissolution risk which would contaminate process water.
Products are manufactured complying with industrial filtration quality‑management standards. Each filter cartridge is individually packaged to prevent dust and particle contamination during storage and transportation. Complete technical datasheets are provided for engineering design reference. On‑site installation inspection is still required before equipment startup to confirm housing interface matching and sealing integrity.
Parker MFNP050‑40N‑ITT is mainly used as pretreatment filter for ultrafiltration water‑treatment systems, and it is also widely deployed in multiple industrial liquid‑filtration scenarios.
Industrial ultrafiltration system pretreatment: Capture sediment, iron‑oxide scale and suspended particles, protect UF membrane elements, reduce membrane cleaning frequency, suitable for raw‑water purification and circulating‑water treatment projects.
Power plant water treatment: Boiler make‑up water and condensate pre‑filtration, remove pipeline rust particles and suspended pollutants.
Food & beverage industry: Raw‑water pretreatment for drinking‑water and beverage production, filter granular impurities.
Chemical industry: Production process‑water filtration and circulating cooling‑water pretreatment.
Municipal water‑supply & reclaimed‑water reuse: Large‑flow raw‑water pre‑filtration for municipal water plants and water‑recycling projects.
Pharmaceutical & cosmetic water‑making: Sanitary‑grade process‑water pre‑filtration for water‑preparation equipment.
According to actual raw‑water turbidity and pollutant composition of different projects, users can configure multi‑stage gradient filtration to achieve better overall filtering performance.
A: It serves as ultrafiltration pretreatment protective filter. It intercepts suspended solids, sediment and granular contaminants inside raw water, reduces pollutant load on ultrafiltration membranes, slows down membrane fouling, cuts chemical cleaning frequency and extends UF membrane service life.
A: There is no fixed time‑based service‑life standard. Service cycle is determined by raw‑water turbidity, pollutant content and actual operating flow. Normally replace the cartridge when inlet‑outlet differential pressure reaches 0.35 MPa.
A: It is a disposable pleated filter element. After filter‑medium gaps are filled with pollutants, back‑washing cannot fully restore original filtration performance. Re‑use after cleaning brings particle‑leakage risk, direct replacement is recommended.
A: It fits 40‑inch large‑flow filter housings with special ITT connection interface. Before purchase, please verify housing interface dimension, inner‑chamber space and pressure‑bearing rating to avoid installation mismatch.
A: Polypropylene material has good tolerance for weak‑acid and weak‑alkali aqueous media. It is not suitable for long‑term operation under high‑concentration strong‑acid or strong‑alkali environment. Please consult technical support for evaluation of special chemical‑medium working conditions.
A: Quantity calculation depends on system total flow rate, single‑cartridge allowable flow and raw‑water quality. It is suggested to calculate required quantity referring to technical datasheet, and reserve proper surplus for fluctuating‑water‑quality working scenarios.
