Reliable Mechanical Seals. Simplified Installation.
Proven Quality.
No Set Screws. No Clips. No problems.
Paradigm Seals™ designs cartridge seals that are first in simplifying installation and removal — protecting pump sleeves and shafts, cutting downtime, and delivering long-lasting performance across every industry.
The Paradigm Advantage ™
FastGrip™
The FastGrip™ Clamp eliminates traditional set screws, preventing shaft and sleeve damage while simplifying installation and removal.
It provides secure, even clamping to ensure reliable torque transmission without distortion or scoring. To ensure proper installation, Paradigm includes a T-handle torque wrench and the correct Torx® drive bit, allowing the FastGrip™ clamp to be tightened accurately every time.
Integrated into the seal design, FastGrip™ delivers faster, more reliable installation.
TriLock Bushing™
The TriLock™ Bushing eliminates the need for traditional centering clips and their removal, dramatically simplifying installation.
It automatically aligns the seal on all three axes, maintaining proper spring position for consistent seal face loading. The bushing locks the seal securely in place, helping prevent uneven wear and premature seal failure.
Because the TriLock™ Bushing is integrated into the seal design, it improves reliability without adding steps or complexity — making consistent, repeatable installations easier to achieve.
QuickCore+™
QuickCore™ Technology allows you to replace only the core sealing element — not the entire seal — delivering a new, factory-tested seal every time at the same cost as repairing a competitor’s cartridge seal, without the added logistics or downtime of sending your seal out for repair.
By eliminating the traditional repair process, QuickCore™ removes the need to clean and decontaminate used seals, gather cartridges for the storeroom, create purchase orders, package and ship seals out, or wait for a quotation — only to find the seal is beyond repair.
FlushControl+™
The FlushControl™ Bushing is an optional feature included with the seal. When used, it is installed directly into the seal as part of the assembly and is designed to manage flush flow to the seal faces — improving lubrication, cooling, and overall seal performance.
When installed, the FlushControl™ Bushing helps reduce excess flush flow, minimizes dilution of the process fluid, conserves water, and improves reliability. It is especially beneficial in applications with flashing or near-flashing fluids, where maintaining proper lubrication and cooling is critical.

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.
