High Flow Cartridges

One element where forty used to be.

Up to 500 GPM per element in 6 to 6.75 inch diameters and 20 to 60 inch lengths. Fewer elements, smaller housings, faster change-outs, and retrofit compatibility with the 3M, Pall Ultipleat, and Parker ParMax formats you may already run.

High flow cartridges serve continuous, high-volume duty with heavy particle loads: seawater and brackish desalination, RO pretreatment, utility and process water, chemicals, petrochemicals, power, food and beverage, and oil and gas. The smaller ClaryFlow Big Buddy line serves water treatment in commercial and industrial facilities where one 30 inch element replaces a row of standard cartridges.

Large flows through standard 2.5 inch cartridges mean dozens of elements, a housing bank sized around them, a seal at every element that can leak, and change-outs that take hours of operator time and stock. The element price is small; the cost is the labour, the downtime, the inventory and the housing capital that the element count drives.

All Big Buddy cartridges: 30 inch media length, all-polypropylene construction, dual O-rings in silicone, Buna-N, FKM or EPDM, free of resin binders, lubricants, antistatic and release agents. The family summary also states 100 to 150 gpm and operation to 79 C (175 F); the variant data above is what we quote until the two are reconciled.

Conditions behind the numbers

The 500 GPM figure is the upper end for one element in water; the flow an element should carry on your duty is set by the solids load and the change-out interval you want. The Clarypleat HF data gives suggested water flows of 660, 1300 and 1900 lpm for 20, 40 and 60 inch elements in ideal conditions. Big Buddy limits are the stated maximum operating conditions.

Retrofit formats and housings

Elements are made in formats that fit 3M (Solventum), Pall Ultipleat and Parker ParMax style housings: a dimensional and format equivalence we confirm against your housing make and model. For new installations, Clary-T HF stainless housings take single or multiple 6 inch elements; see filter housings. Pleated HF data is on the pleated page.

Why switch from standard 2.5 inch cartridges to high flow?

Element count. One high flow element handles up to 500 GPM, replacing dozens of standard cartridges. That means smaller housings, fewer seals to leak, and change-outs measured in minutes instead of hours. On desalination and RO pretreatment duties the labour and downtime savings usually pay for the conversion within the first year.

Will Gopani high flow elements fit my existing housing?

In most cases yes. Our elements are retrofit-compatible with common high flow formats including 3M (Solventum), Pall Ultipleat, and Parker ParMax style housings. Send your housing make and model and we will confirm fitment and quote the equivalent element.

What ratings and media are available?

Common ratings are 1, 5, 10, 20, and 40 micron across pleated, melt blown, string wound (Clarywound Extreme, GF, 3X, Ultra, CPU), and activated carbon media, in 20, 40, and 60 inch lengths at 6 to 6.75 inch diameter. Flow can run inside-to-out or outside-to-in depending on the format.

When should a high flow cartridge be changed?

At the terminal pressure drop for the element and housing. High dirt-holding designs stretch the interval; we set the change-out point with you from the housing rating and your process.

Do you make custom sizes and end caps?

Yes. Custom high flow element designs, OEM variants and special end-cap configurations are available, as are custom high flow housings, including the Clary-T HF stainless housing for 20, 40 and 60 inch elements at 6 inch diameter.

What is ClaryFlow Big Buddy?

A 30 inch large-format cartridge line in melt blown, activated carbon and pleated media, with EPDM double O-ring seals as standard and other elastomers on request. It is used for sediment, chlorine, taste and odour removal in commercial and industrial water filtration.

Do you supply tubular membrane modules?

Yes. Gopani supplies Porex TMF tubular membrane filter modules: membrane tubes on a PE or PVDF sintered porous substrate, for solid-liquid separation at solids levels up to 5% by weight, with a PVDF-on-PVDF version for high temperature and the full pH range of 0 to 14.

Our catalogue states that high flow cartridges are made under an ISO 9001 quality management system, with DAkkS-accredited testing. What we put on paper for your plant is the conversion itself: today's element count, change-out time and annual element spend, next to the high flow equivalent, with the fitment confirmed against your housing drawing.

Send the housing bank size and flow. We will show the high flow conversion: element count, change-out time, and annual cost, side by side with today.
