Customer Background
A mid-sized mechanical manufacturing company in North America specializes in precision fabrication of automotive components and construction machinery parts. The facility operates multiple CNC machining centers and cleaning production lines, requiring substantial volumes of industrial circulating cooling water and cleaning water daily. As production capacity increased, the existing single-bag filters became insufficient, leading to elevated levels of iron chips and suspended solids in the circulating water. This compromised surface finish quality during machining and accelerated coolant degradation.
Project Challenges
The customer faced three major issues: first, frequent clogging of single-bag filters required shutdowns for filter bag replacement every shift, severely disrupting continuous production cycles; second, the original equipment’s inlet and outlet configuration was top-in and top-out, resulting in an inefficient piping layout that prevented complete drainage. Residual liquid accumulated after shutdowns, making maintenance cumbersome and prone to leaks; third, the filter housing was made of ordinary carbon steel with inadequate surface protection, causing noticeable corrosion in the high-humidity workshop environment, posing a risk of contaminating the coolant.
Solution
After reviewing the customer’s original filter drawings and operating parameters, we recommended the JYMF-6P/CS 6-bag carbon steel filter as a tailored solution. This design features a bottom-in, bottom-out flow path, directly compatible with the customer’s existing piping infrastructure without requiring extensive pipeline modifications. The housing is manufactured to ANSI B16.5 150# flange standard, with a working pressure set at 100 PSI—meeting the requirements of the customer’s circulating pump discharge pressure. Filter bags are made of 100-micron PE material with full hot-melt welding, ensuring optimal balance between filtration accuracy and flow rate.
During installation and commissioning, the customer particularly appreciated the standard NPT threaded interface layout. Pressure gauge ports were pre-installed on both inlet and outlet pipes, while the top cover vent valve and bottom drain valve were fully included. On-site, only piping connections were needed before operation. The exterior was coated with the customer’s specified gray paint, matching the appearance of other equipment in the workshop for visual consistency.
Operational Results
Since commissioning, the unit has easily met the circulating water demands of the customer’s three production lines. The multi-bag parallel configuration allows continued operation when replacing individual bags, enabling maintenance without production downtime. The previously required shutdown every four hours for cleaning has been extended to routine inspections every 48 hours. Combined with the bottom-in, bottom-out flow and the bottom drain valve, accumulated sediments can be quickly and regularly discharged, significantly reducing abnormal filter clogging. Pressure readings remain stable between 65–80 PSI, with a much slower pressure differential rise compared to the previous system.
Customer Feedback
In follow-up email communication, the plant maintenance supervisor reported that the new filter’s operational stability exceeded expectations. The coolant change interval has been extended from monthly to quarterly, reducing consumable costs by approximately 40% alone. Additionally, the use of standard NPT interfaces allowed them to reuse their own pressure gauges and valve spare parts, greatly improving maintenance convenience. The customer has now included this model in the standardized spare parts list for their U.S. facility and recently placed a repeat order based on the original drawings, eliminating the need to reconfirm technical details.
Summary
This case demonstrates that in industrial water treatment scenarios involving multiple impurities and continuous operation, properly selected high-flow multi-bag filters, combined with appropriate flow design and standard interface configurations, can effectively enhance system reliability and reduce overall operational and maintenance costs. Our company’s ability to quickly respond based on the customer’s original drawings also provides overseas long-term customers with reliable replacement support.
