Mechanical Seal Solutions for Wastewater Pumps
Picture this: It’s 6:30 AM. Your shift just started at the municipal wastewater treatment plant. A thunderstorm rolled through overnight, and now the grit removal system is overloaded. Staff are calling out. One of your Flygt submersible pumps just failed—again.
You pull the pump, crack it open, and there it is: a shredded mechanical seal, ground down by abrasive grit and sand.
Welcome to the reality of wastewater management.
At Apex Sealing, we hear stories like this all the time. Submersible pumps are built to work hard—but their mechanical seals often aren’t built to survive the punishing environments they’re placed in. Between unpredictable influent, abrasive sludge, and non-stop runtime, even the most reliable OEM seals can wear out faster than expected.
But here’s the good news: You don’t need a full system overhaul. You just need the right seal, one that’s designed for your actual operating conditions.
Why Seals Fail in Wastewater Applications
Mechanical seals in wastewater applications face some of the harshest conditions in the industry:
Grit, sand, and debris accelerate wear on seal faces
Variable flows and solids create pressure fluctuations and seal misalignment
High run-time cycles leave little time for systems to recover between stressors
Too often, standard OEM seals aren’t built to withstand this kind of abuse. That’s where Apex comes in.
Better Materials, Smarter Design
We stock over 50 Flygt-style mechanical seals, designed specifically to handle the real-world demands of wastewater environments. What makes ours different?
💧 Carbide face materials that hold up against grit and sand
💧 Dual seal configurations that offer a backup layer of containment
💧 Comparable or better performance than OEM—at a lower cost
How We Help Wastewater Facilities Like Yours
We’ve partnered with wastewater operators across the country to solve chronic seal failures and reduce pump downtime. Here’s how:
✅ Matching seal materials to actual influent conditions
✅ Maintaining stock of high-demand seal sizes for quick delivery
✅ Offering tech support and field insight from people who know the industry
The result? Fewer failures, less downtime, and happier operators.
A Small Change Can Make a Big Difference
If your team is tired of pulling the same pumps again and again, it’s time to dig deeper. Most chronic failures trace back to one thing: the wrong seal for the job.
At Apex Sealing, we’re not just a parts supplier—we’re your partner in solving problems before they shut your system down.
