Internal Pressure High Flow Filter Cartridge BHP

Internal Pressure High Flow Filter Cartridge BHP

BHP series high-flow filter cartridges adopt a 6-inch large-diameter single-open design. Featuring an ultra-large filtration area and optimized flow channels, they deliver high dirt-holding capacity, low resista nce and efficient filtration. With an inside-to-outside flow path, particles are trapped firmly inside the cartridge. High-precision fiber media plus a reinforced structure ensure stable filtration and excellent pressure resistance. Made of full PP material with thermal fusion bonding, no adhesives or additives are used. Low extractables and wide chemical compatibility suit complex fluid filtration. Compact and easy to install, the cartridges save space and serve as an efficient solution for industrial filtration.

BHP Series High Flow Filter

BHP Series high flow filters adopt a 6-inch large-diameter single-open end internal pressure structure. Supported by an ultra-large filtration area and fluid-mechanically optimized flow channel design, they form an efficient filtration system featuring high dirt holding capacity and low pressure drop, with multiple core advantages suitable for demanding industrial working conditions:

I. Advantages in Structure & Fluid Design

Internal pressure filtration (inside-to-out flow)

Liquid permeates from the interior to the exterior of the filter element, while solid contaminants are trapped inside the filter medium to prevent outward diffusion. The outer surface of the filter remains clean, greatly reducing the risk of secondary contamination during filter replacement. Meanwhile, it avoids filter cake shedding that pollutes downstream pipelines, ensuring stable filtrate quality.

6-inch large-diameter single-open end structure

Compared with conventional 4-inch high flow filters, the effective filtration area per filter cartridge is significantly increased. Under the same flow rate, fewer filter elements are required, and matched filter housings occupy less floor space, cutting equipment investment and on-site installation space. The single-open end cap fits standard high flow filter housings; installation and removal are simple and efficient, lowering maintenance labor hours.

Optimized flow channels for low differential pressure operation

Flow channels are optimized via simulation to achieve uniform fluid distribution and minimize turbulence and local resistance loss. A low operating differential pressure can be maintained even under high flow conditions, reducing pump load and energy consumption. In addition, the differential pressure rises moderately, extending the online service life of the filter.

II. Advantages in Filtration Performance

Ultra-large filtration area & high dirt holding capacity

Pleated filter media is fully deployed to maximize the effective filtration area, enabling retention of large volumes of suspended solids and colloidal contaminants. Under identical feed water quality, the filter clogging cycle is prolonged, reducing frequent shutdowns for replacement and improving continuous system operation efficiency.

Stable high-precision interception & excellent differential pressure resistance

Graded high-purity polypropylene fiber filter media is adopted, paired with an integrated reinforced support skeleton to prevent filter medium collapse under pressure. The filter can withstand higher operating differential pressure. Filtration accuracy remains consistent amid fluctuations in feed water quality and sudden flow changes, preventing contaminant breakthrough.

III. Advantages in Material & Manufacturing Technology

Integrally thermally fused all-polypropylene (PP) construction, no adhesives

Filter media, support skeleton and end caps are all made of high-purity PP and integrated by thermal fusion welding. No adhesives, resins or other bonding agents are used. There is minimal extractables without chemical binder leaching, eliminating contamination of process fluids.

Excellent chemical compatibility

Polypropylene resists acids, alkalis, salt solutions and most organic solvents. It suits a wide range of complex fluids such as purified water, chemical raw materials, coatings, electroplating solutions and water treatment chemicals, covering extensive working conditions.

IV. Advantages in Operation & Maintenance

Lower overall operating costs

Each filter cartridge delivers a high flow rate and longer service life, cutting filter procurement consumption. Low pressure drop reduces power consumption of pumps, and fewer shutdowns for replacement lead to markedly lower comprehensive maintenance costs compared with conventional pleated filters.

Wide adaptability to industrial applications

With a compact modular design, the filters can be used individually or in parallel flexibly. They are widely applied in pre-filtration processes including RO cartridge filtration, purified / ultrapure water systems, chemical raw material filtration, municipal water treatment, electroplating, food & beverage processing, fine chemical industry, and other precision filtration scenarios.

Safe, eco-friendly for clean production

The materials meet industrial fluid cleanliness standards with low risk of fiber shedding. Spent filters can be collected and recycled without persistent pollutants, meeting requirements for clean production and environmental regulation.
