Parker filters MFNP050‑40N‑ITT for Ultrafiltration Pretreatment System

Parker filters MFNP050‑40N‑ITT serves as an essential pretreatment element for industrial ultrafiltration systems. This liquid filter delivers high dirt‑holding capacity and effectively reduces the frequency of cartridge replacement. Made of high‑performance pleated polypropylene material, it fits standard large‑flow filter housings and can work together with High‑flow water filter cartridge and Water Filtration PP Pleated Filter to build complete multi‑stage water‑treatment sequences. It has gained wide recognition for process water purification projects in power, chemical, food and beverage industries around the world.

Product Introduction

Parker filters MFNP050‑40N‑ITT is a large‑diameter high‑flow pleated filter cartridge specially developed for ultrafiltration pretreatment protection. As a reliable drop‑in replacement filter element, it is installed at the front‑end of ultrafiltration membrane modules. Its core mission is to capture suspended solids, colloids, fine sediment, pipeline rust and granular contaminants in raw water. By removing most particulate impurities in advance, it greatly mitigates membrane fouling risk, decreases chemical cleaning cycles and extends the service life of costly ultrafiltration membrane components.

Compared with conventional small‑diameter filter cartridges, MFNP050‑40N‑ITT adopts enlarged diameter pleated construction, which significantly enlarges the effective filtration area per single element. Under identical flow conditions, fewer cartridges are required inside filter housings. For system integrators and end users, this brings tangible benefits: fewer filter housings, simplified installation work and lower long‑term operation and maintenance expenditure. When designing a complete water‑treatment skid, users can pair it with High Flow Pleated Filter Cartridge for Industrial UF System and Replace Pall Marksman High‑Flow Cartridge to achieve multi‑grade gradient pre‑filtration interception effect.

This filter cartridge is built with full polypropylene material. Advanced thermal‑bond pleating technology replaces glue bonding, eliminating the risk of secondary water pollution caused by adhesive dissolution under water scouring. End caps and inner‑outer support skeletons are integrally molded, maintaining stable mechanical performance under long‑term high‑flow impact and frequent pressure fluctuations. Whether you are commissioning brand‑new ultrafiltration water‑making equipment or replacing spare parts for existing water‑treatment lines, Parker filters MFNP050‑40N‑ITT can deliver consistent and dependable pretreatment filtration performance.

Working Principle

Parker filters MFNP050‑40N‑ITT operates on surface‑depth composite pleated filtration principle. After raw water enters the filter housing, fluid flows radially inward from the outer surface of the filter cartridge. Large solid particles are first trapped on the outer pleated surface, while fine micro‑impurities penetrate into polypropylene fiber layers and are trapped inside dense fiber gaps.

Thanks to the large‑area pleated layout, pollutants are evenly distributed across the whole filter medium instead of accumulating on only partial surface areas. This slows down differential‑pressure rising speed, maximizes dirt‑holding capacity and prolongs the service cycle of the filter cartridge. When the pressure difference between inlet and outlet reaches the preset threshold, it indicates that filter medium is saturated with intercepted pollutants, and operators need to replace the whole filter cartridge.

It acts as the front‑line protective barrier for ultrafiltration equipment. Without this pretreatment barrier, raw water carrying particles would flow directly onto UF membrane surface. Solid contaminants will deposit on membrane surface, block membrane pores, accelerate fouling, increase chemical cleaning frequency and may even cause irreversible membrane damage. When used in series with PFTM11UNF high flow filter cartridge for multi‑stage combined filtration, the overall stability of the water‑treatment system can be further improved. Please note that this cartridge only removes solid particulate contaminants and cannot eliminate dissolved ions, so it only undertakes pretreatment work before ultrafiltration membranes.

Technical Parameters

Quality Control

Every batch of Parker filters MFNP050‑40N‑ITT undergoes complete process inspection and finished‑product testing before shipment. Incoming material inspection is performed for polypropylene filter media, support skeletons and end‑cap raw materials to guarantee raw‑material consistency. During production, sampling checks cover pleating amplitude, thermal‑bond strength and end‑cap sealing performance.

Finished‑product tests include bubble‑point integrity test, cyclic pressure impulse test and water‑flow pressure‑drop inspection. Defective units with medium cracks, poor sealing or structural looseness will be fully screened out. The glue‑free thermal‑bond process avoids adhesive dissolution risk that would contaminate process water.

Products are manufactured under industrial filtration quality‑management standards. Each filter cartridge is individually packaged to prevent dust and particle contamination during storage and transit. Complete technical datasheets are provided for engineering reference. On‑site installation inspection is still required before startup to confirm housing interface matching and sealing integrity.

Application Fields

Parker filters MFNP050‑40N‑ITT is primarily used as pretreatment filter for ultrafiltration water‑treatment systems, and it is also widely applied 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, fit 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, remove granular impurities.

Chemical industry: Process‑water filtration and circulating cooling‑water pretreatment for chemical production lines.

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 on‑site raw‑water turbidity and pollutant composition, users can configure multi‑stage gradient filtration to achieve better overall filtration performance.

FAQ

Q1: What is the function of Parker filters MFNP050‑40N‑ITT in ultrafiltration equipment?

A: It serves as ultrafiltration pretreatment protective filter. It intercepts suspended solids, sediment and granular contaminants in raw water, lowers pollutant load on ultrafiltration membranes, slows down membrane fouling, reduces chemical cleaning frequency and extends UF membrane service life.

Q2: How long is the service life of Parker filters MFNP050‑40N‑ITT?

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.

Q3: Can Parker filters MFNP050‑40N‑ITT be cleaned and reused after contamination?

A: It is a disposable pleated filter element. After filter‑medium gaps are filled with pollutants, back‑washing cannot fully restore original filtration performance. Reuse after cleaning brings particle‑leakage risk, direct replacement is recommended.

Q4: What filter housing is compatible with Parker filters MFNP050‑40N‑ITT?

A: It suits 40‑inch large‑flow filter housings with special ITT connection interface. Before purchase, please verify housing interface dimension, inner‑chamber space and pressure rating to avoid installation mismatch.

Q5: Can MFNP050‑40N‑ITT run under strong‑acid and strong‑alkali operating conditions?

A: Polypropylene material performs well in weak‑acid and weak‑alkali aqueous media. It is not suitable for long‑term exposure to high‑concentration strong acid or strong alkali. Please contact technical support for evaluation of special chemical‑medium working conditions.

Q6: How many MFNP050‑40N‑ITT cartridges do I need for my ultrafiltration system?

A: Quantity calculation depends on system total flow rate, single‑cartridge allowable flow and raw‑water quality. It is recommended to calculate quantity referring to technical datasheet, and reserve proper surplus for fluctuating‑water‑quality scenarios.
