A field guide to API 682 seal flush plans: what Plans 11 through 76 do, how each one fails on real pumps, and how to match a plan to the fluid, temperature, and pressure margin.

Flush water and liquid barriers don’t work with dry solids. Here’s why packing and mechanical seals fail on powder equipment, and what an air seal needs to work.

The SEPCO EXP Bearing Isolator is a non-contact, permanent bearing protection device. It is engineered to provide superior protection against contaminants while retaining lubricant in the bearing housing.

The short answer A mechanical seal does not hold pump pressure steady. It reacts to whatever pressure sits in the seal chamber, and the pump sets that pressure: impeller design, wear ring and back vane clearances, the throat bushing and the flush plan. Two numbers decide whether the seal faces stay closed and cool. Seal … Continue reading "Seal Chamber Pressure and Balance Ratio: What Keeps Mechanical Seal Faces Closed"

A split seal that fails in six weeks usually isn't a bad seal — it's a good seal installed on worn equipment. Here's our 12-step field checklist, from lockout/tagout through documentation, including the split-line step most installation guides leave out entirely.

A complete inventory of your sealing equipment is the first step to less downtime, leaner inventory, and lower water costs.

Keeping Contaminants Out and Reliability Up in the World's Toughest Applications

Valve packing may not get much attention—but in industrial operations, it’s one of the most critical components for emissions control, safety, and reliability. At its core, valve packing is braided sealing material—commonly graphite, PTFE, carbon fiber, or engineered blends—compressed around the valve stem. While the stem moves to open and close the valve, process fluid must remain contained. … Continue reading "Valve Packing for Industrial Applications: Improve Safety, Compliance, and Reliability"

By aligning sealing technology with real-world operating conditions, SEPCO helps pulp and paper mills reduce total cost of ownership, improve safety, and keep operations running without interruption.

In the water and wastewater treatment industry, regulatory compliance isn’t just a box to check—it’s the backbone of safe, efficient operations. Treatment plants handle everything from municipal sewage to industrial effluents, where leaks or failures can lead to environmental disasters, hefty fines, and public health risks. Standards like the EPA’s Clean Water Act, OSHA safety … Continue reading "Navigating Regulatory Compliance: SEPCO’s Sealing Solutions for Water and Wastewater Treatment Plants"
