Reliable MXGP400-40N-SM Replacement Filter Cartridge | Parker Fulflo MaxGuard Compatible
The MXGP400-40N-SM Replacement Filter Cartridge from MemKway is designed as a reliable alternative to the Parker Fulflo MaxGuard Series MXGP400-40N-SM. Featuring 40 micron absolute polypropylene pleated media, a 40-inch large-diameter configuration, and Buna-N sealing, it provides efficient coarse particle removal, high contaminant capacity, and stable filtration performance for demanding industrial liquid systems.
With a 226 O-ring positive seal and flat cap with integrated handle, the cartridge provides secure installation and convenient change-out. Its relatively open 40 micron filtration grade makes it particularly suitable for upstream industrial prefiltration, cooling water, process water, chemical processing, power generation, and high-solids-load applications where larger suspended contaminants should be removed before finer downstream filtration.

5. Typical Applications
The MXGP400-40N-SM Replacement Filter Cartridge is particularly suited to high-volume systems requiring 40 micron absolute filtration, high contaminant capacity, and efficient upstream particle removal.
- Industrial Upstream Prefiltration: Removal of larger suspended contaminants before finer downstream cartridges.
- Cooling Water Systems: High-capacity particle removal from industrial cooling and recirculation water.
- Industrial Process Water: Pretreatment of plant, utility, and high-volume process water streams.
- Power Generation: Prefiltration of cooling and compatible utility water systems.
- Chemical Processing: Coarse particulate removal from compatible chemicals and process liquids.
- Oil & Gas Processing: Removal of larger suspended solids from compatible process fluids and water streams.
- Industrial Wastewater: Initial particulate removal before finer filtration or downstream treatment.
- Equipment Protection: Upstream contaminant control to reduce solids loading on finer filters and downstream equipment.
6. Key Features of MXGP400-40N-SM Replacement Filter
- Parker MaxGuard Compatible Design: Designed as a replacement for Parker Fulflo MaxGuard MXGP400-40N-SM with a compatible large-format cartridge configuration.
- 40 Micron Absolute Filtration: Provides 40 μm absolute particle retention at β=5000 / 99.98%, suitable for upstream industrial filtration.
- Optimized for Coarse Particle Removal: The 40 micron grade is particularly suitable for capturing larger suspended contaminants before finer downstream filtration stages.
- High Dirt-Holding Capacity: Large pleated filtration area provides increased contaminant-loading capacity for demanding industrial systems.
- Low Clean Pressure Drop: The relatively open 40 micron media provides a very low flow resistance compared with finer MaxGuard grades; Parker lists a flow factor of 0.00023 psid/gpm @ 1 cks.
- Pleated Polypropylene Media: Provides efficient contaminant capture and broad compatibility with many industrial liquid applications.
- Buna-N Sealing: Equipped with a Buna-N (NBR) seal for applications where nitrile elastomer compatibility is appropriate.
- 226 Positive O-Ring Seal: Provides secure cartridge seating and reliable sealing in compatible housings.
- Integrated Handle: Flat closed end with handle simplifies cartridge installation and routine change-out.
7. Quality & Regulatory Compliance
- ISO 9001:2015: Manufactured in a certified facility with strict quality controls.
