Product Description
Parker MFNP005‑40N is a high‑precision high‑flow pleated filter cartridge under the Parker Fulflo Mega‑Flow product portfolio, widely adopted for demanding raw‑water purification, critical process‑liquid filtration and RO security pre‑filtration across multiple high‑requirement industrial sectors. It adopts classic 6‑inch (152 mm) large outer diameter and 40‑inch (1016 mm) standard length, with large effective filtration area far superior to traditional 2.5‑inch small‑size filter cartridges. A single MFNP005‑40N can replace dozens of conventional small‑sized cartridges, greatly reducing the quantity of elements installed inside filter housings, simplifying skid layout and cutting overall project investment cost.
The whole filter cartridge is constructed with full polypropylene material system: multi‑layer gradient pleated polypropylene filter media, reinforced PP inner‑outer support cages, glass‑fiber‑filled polypropylene end caps and integrated lifting handle. Thermal‑fusion hot‑melt welding is applied throughout manufacturing without adhesive bonding, eliminating risks of glue dissolution, fiber shedding and secondary fluid contamination. Standard Buna‑N nitrile O‑ring ensures reliable sealing performance and prevents bypass of unfiltered liquid. Operators can finish replacement work without special tools, cutting on‑site maintenance labor and system downtime.
As a universal flat‑cap base model, MFNP005‑40N fits perfectly for standard Mega‑Flow filter housings without any mechanical modification. With stable 0.5‑μm nominal filtration rating, it can trap ultra‑fine suspended particles, fine sediment, tiny flocs and colloidal contaminants that easily damage RO membranes. The maximum continuous operating temperature reaches 82°C, showing outstanding chemical compatibility for neutral aqueous solutions as well as weak acid and weak‑alkali process fluids, serving as reliable consumables for high‑standard industrial water‑treatment systems.
Working Principle
Parker MFNP005‑40N high‑flow filter cartridge operates on proven outside‑in depth filtration principle. Untreated raw water or industrial process liquid enters filter housing under system pressure and flows towards the outer pleated surface of the cartridge. Multi‑layer gradient pore structure completes graded interception step‑by‑step: coarse particles and large flocs are trapped on outer coarse‑pore layer, while ultra‑fine suspended solids and tiny colloids are captured by inner fine‑pore media layers.
Gradient design maximizes dirt‑holding volume and slows differential‑pressure rising speed. After full purification, liquid flows inward through inner support core and flows towards downstream RO, UF and other precision separation equipment. Reinforced inner‑outer cages strengthen structural rigidity to resist high‑velocity water‑flow impact and avoid media collapse or fluid bypass. When differential pressure across inlet‑outlet rises to 25‑30 PSID threshold, operators shall carry out cartridge replacement timely to restore rated flow rate and filtration performance of the whole system.

FAQ
Q1: What are the key specifications of Parker MFNP005‑40N?
A1: It is Mega‑Flow series high‑flow pleated filter cartridge, 0.5‑micron nominal precision, 40‑inch length, 6‑inch outer diameter, Buna‑N seal material, maximum continuous operating temperature 82°C, adopting full polypropylene thermal‑fusion construction。
Q2: What is the difference between MFNP005‑40N and MFNP010‑40N?
A2: MFNP005‑40N is 0.5‑micron grade for ultra‑fine particle interception, applied for high‑precision RO pretreatment; MFNP010‑40N is 1‑micron version, used for general‑purpose industrial pre‑filtration scenarios. Users can select according to raw‑water SDI and process requirements.
Q3: When should I replace MFNP005‑40N filter cartridge?
A3: Replace the cartridge when system inlet‑outlet differential pressure reaches 25‑30 PSID, or obvious flow‑rate drop occurs. Even without high pressure‑drop, periodic replacement according to on‑site water‑quality condition is recommended.
Q4: Can MFNP005‑40N be cleaned and reused?
A4: It is disposable polypropylene pleated filter element. After colloids and fine particles block internal pores, cleaning cannot fully restore filtration performance. Direct replacement is advised after pressure‑drop alarm.
Q5: What fluid environment is not suitable for MFNP005‑40N?
A5: It is not fit for working fluid containing strong oxidants, strong acid or strong alkali. Avoid long‑term exposure to high‑concentration organic solvents to prevent damage to polypropylene materials.
