FBU Successfully Delivers Type GSMA Seal for Durco® Mark3 pump

Durco Mark 3 process pumps are widely adopted across the grain and oil processing industry. The split mechanical seals supplied as original equipment come with notable drawbacks. Full disassembly and reassembly involve complicated procedures, requiring repeated coaxial alignment during on-site fitting and highly skilled maintenance personnel. When exposed to media containing meal residues and fine oil particles, these seals are prone to abrasive wear and leakage, leading to frequent part replacements. This results in excessive long-term costs for spare parts procurement and downtime maintenance.

FBU mass-produces the proven GSMA standard cartridge mechanical seal. Its standardized modular design delivers a perfect fit for this pump range, enabling direct replacement of the original split seals without any pump modification. The unit features a pre-assembled, pre-calibrated integrated structure that eliminates on-site adjustment. All components including rotating and stationary rings, springs and gaskets are fully precision-matched and pre-compressed at the factory. Installation only requires positioning and fastening on-site, drastically cutting maintenance downtime and mitigating premature leakage caused by human assembly errors.

Tailored to the grain and oil operating conditions with particulate and mildly corrosive media, the GSMA seal upgrades the materials of its friction pairs and elastic elements to boost resistance against erosion and oil-induced corrosion. An internal flow guide structure prevents residue buildup that could jam the springs, sustaining leak-free and stable pump operation over extended periods.

We deliver a one-stop service package covering working condition customization, product supply, on-site installation and commissioning. The service life of our seals matches that of original OEM seals. By cutting frequent spare part expenses, labor costs for repairs and production losses from shutdowns, we comprehensively lower overall equipment operation and maintenance costs, offering a long-lasting and dependable sealing solution for critical fluid transfer equipment in grain and oil manufacturing facilities.
