Viscous fluids like syrups, resins, and adhesives can overwhelm traditional seals—but not the Flexaseal MLC3. This modular triple lip cartridge seal handles thick, sticky media with ease, achieving reliable sealing at lower speeds without the need for complex seal support systems. Ideal for pumps, mixers, and agitators, the MLC3 delivers exceptional performance in high-viscosity, slow-moving, and demanding applications across multiple industries.

Controlling vapour pressure in mechanical seal chambers is critical to avoiding flashing and seal failure. API piping plans like Plan 11 and Plan 14 help maintain seal face stability without a heat exchanger by increasing seal chamber pressure and removing heat. Learn how to improve seal reliability using pressure-driven flush plans with help from Specialised Flow Solutions.

There are two main classifications of metal bellow seals: edge welded metal bellows an formed bellows. Here we discuss the advantages and...

The Flexaseal Style 85M Split Cartridge Mechanical Seal is engineered specifically for mixers and agitators, offering a reliable sealing solution without the need for equipment disassembly. Its innovative split design simplifies installation and maintenance, reducing downtime and labor costs. Built for challenging applications, the 85M delivers durability, performance, and efficiency where it matters most.

Mechanical seals are made from a range of materials like steel, rubber, silicon, carbon, and PTFE. Their precise design makes proper storage essential to maintain performance. When stored correctly in a clean, temperature and humidity-controlled environment, mechanical seals can typically be kept safely for up to five years without compromising their integrity.

Failure to select the proper mechanical seal type can lead to loss of pump integrity, breakdowns and costly repairs.

What are your mechanical seal faces showing you? Heat checking? Coking? Blistering? Understand the causes and troubleshoot these issues.

While braided packing can be a solution for many services, its upkeep requirements often force operators to consider mechanical seals.
