Understanding Oversized Bore Mechanical Seals
When selecting a mechanical seal, confirming the correct bore size is just as important as choosing the right seal type and face combination. For many pumps, a standard bore will suffice. However, certain pump models and applications require an oversized bore. Misidentifying this detail can lead to incorrect orders, failed installations, and costly downtime.
This article explains what an oversized bore is, when it’s required, and how Paradigm Seals™ makes the selection process simple.
The Paradigm i-Seal™ Story: Redefining Mechanical Seal Innovation
The mechanical seal industry has long relied on legacy designs with incremental improvements. Paradigm Seals® took a different approach — one that prioritizes simplicity, reliability, and long-term value for operators. The result is the i-Seal® family of cartridge seals, engineered to eliminate common sealing frustrations while delivering consistent performance across industries.
5 Ways Paradigm Seals™ Simplify Installation and Reduce Maintenance Costs
Mechanical seals are often associated with complex installation, frequent maintenance, and costly downtime. Paradigm Seals® were engineered to eliminate these challenges. By combining robust materials with simplified cartridge design, Paradigm helps facilities save both time and money while maintaining reliable pump operation.
The True Cost of Mechanical Seal Downtime — and How to Prevent It
Unplanned downtime caused by mechanical seal failure is one of the most expensive issues in pump operation. Beyond the direct cost of replacing a seal, downtime can result in lost production, safety risks, and environmental compliance violations. Understanding the full cost impact of seal downtime highlights the importance of proactive maintenance and reliable seal selection.
Why Cartridge Seals Save You Time and Money vs. Packing
Pump packing has been used for decades as a sealing method, but modern cartridge mechanical seals offer significant advantages in efficiency, reliability, and cost. For facilities focused on reducing downtime and total cost of ownership, replacing packing with cartridge seals is often the most effective upgrade.
Choosing the Right Seal for Water Treatment vs. Chemical Processing Applications
Mechanical seals must be matched not only to pump design but also to the application environment. Two of the most common — yet very different — applications are water treatment and chemical processing. Each presents unique challenges that affect seal selection, materials, and maintenance strategies. This article compares both environments and outlines best practices for choosing the correct Paradigm seal.
Seal Solutions for Aurora, Durco, and Worthington Pumps

Repair vs. Replace: Making the Right Decision for Mechanical Seals
When a mechanical seal fails, maintenance teams often face a critical decision: repair the existing seal or replace it with a new one. Both options have advantages, and the right choice depends on the value of the seal, the criticality of the equipment, and the cost of downtime. This article provides a framework for making an informed decision.
Troubleshooting Mechanical Seal Failures: Common Causes and Corrective Actions
Mechanical seal failures account for a significant percentage of pump downtime across industries. While seals are engineered for reliability, improper installation, inadequate operating conditions, or material incompatibility can shorten service life. Troubleshooting failures begins with understanding the most common causes and implementing corrective actions to prevent recurrence.
Mechanical Seal Maintenance Checklist for Long-Term Reliability
Mechanical seals are critical components in pump systems, designed to prevent leakage, maintain pressure, and protect equipment. Their reliability directly affects production efficiency, operating costs, and plant safety. Proactive maintenance is the most effective way to extend seal life, reduce unplanned downtime, and ensure consistent performance. This checklist outlines best practices for routine inspections, scheduled maintenance, and long-term reliability.
Top 5 Mistakes to Avoid When Installing Mechanical Seals
Mechanical seals are precision components — and even small mistakes during installation can lead to premature failure. Whether you’re installing a single cartridge seal or a dual cartridge seal, avoiding these common pitfalls will save time, money, and downtime.
When to Replace a Mechanical Seal: Signs of Wear & Failure
Mechanical seals are the heart of pump reliability. But like any wear part, they don’t last forever. Waiting too long to replace a failing seal can lead to unexpected downtime, equipment damage, or costly leaks. In this article, we’ll cover the top signs it’s time to replace your mechanical seal and how to extend its lifespan.
Single vs. Dual Cartridge Seals: Which One Do You Need?
