Parker High Flow Filter for Industrial Water Treatment Pretreatment

Parker high flow filter covers complete filter housings and matching pleated filter cartridges from the Fulflo Mega‑Flow series, delivering integrated high‑volume filtration solutions for industrial water treatment and membrane protection. Thanks to its 6‑inch large‑diameter design, the system achieves high single‑unit flow and outstanding dirt‑holding capacity, minimizing cartridge quantity and overall equipment footprint. Many system integrators combine RTM41HF050E large‑diameter filter element and PFTM11UNF pleated filter cartridge with Parker high flow filter assemblies to build multi‑stage pretreatment loops, stabilizing feed‑water quality and extending service life of downstream RO and UF membrane modules.

Product Description

Parker high flow filter refers to the complete industrial filtration assembly consisting of high‑flow filter housing and matched Fulflo Mega‑Flow series filter cartridges, widely used for large‑flow raw water purification, process liquid filtration and security pre‑filtration before reverse osmosis and ultrafiltration systems. Different from ordinary small‑bore filter equipment, this product adopts a 6‑inch large‑diameter filter cartridge design. One single high‑flow filter cartridge can reach the flow rate equivalent to multiple traditional 2.5‑inch filter cartridges, which greatly reduces the total number of internal filter elements inside the housing, simplifies skid layout, saves installation space and cuts project capital investment.

The supporting filter cartridges include classic models MFNP005‑40N, MFNP010‑40N, MFNP050‑40N and MFNP050‑40N‑ITT, covering 0.5 μm‑10 μm filtration precision, with 20‑inch and 40‑inch mainstream lengths. There are universal flat end‑cap and special ITT customized end‑cap versions to adapt to different housing internal structures. The filter cartridges adopt full polypropylene gradient pleated material, thermal‑fusion hot‑melt welding without adhesive glue, avoiding fiber shedding and secondary pollution. Standard Buna‑N nitrile O‑ring provides reliable sealing performance, and the integrated lifting handle supports tool‑free quick replacement, lowering on‑site maintenance labor intensity and system downtime.

The matched Parker high flow filter housing is made of high‑strength material options such as carbon steel or stainless steel, suitable for 24‑hour continuous heavy‑duty industrial working conditions. The maximum continuous operating temperature of the whole set can reach 82 °C, with good chemical compatibility for neutral, weak acid and weak‑alkali process fluids. It is widely selected in power, petrochemical, food‑beverage, electronic manufacturing and municipal water‑treatment projects, applicable to both new‑built systems and old‑equipment renovation scenarios.

Working Principle

Parker high flow filter assembly operates based on outside‑in depth filtration principle. Under system pressure, raw water or industrial process liquid enters the filter housing body and flows toward the outer pleated surface of the internal Mega‑Flow filter cartridge. Multi‑layer gradient pore filter media realizes graded interception: coarse sediment and large flocs are trapped on the outer coarse‑pore layer, while fine suspended solids, colloidal particles and tiny impurities are intercepted by inner fine‑pore layers.

The gradient structural design maximizes dirt‑holding space and slows the rising speed of inlet‑outlet differential pressure. After being purified step by step, liquid converges through the inner support core of filter cartridge and flows steadily to downstream RO, UF and other precision separation equipment. Reinforced inner‑outer support cages effectively resist high‑speed water‑flow impact and prevent filter media collapse and liquid bypass. When the inlet‑outlet differential pressure rises to 25‑30 PSID alarm threshold, operators need to replace the internal filter cartridge timely to restore rated flow and filtration efficiency of the whole high flow filter system.
