Flex-a-Seal Mechanical Seals FAQ
What Flexaseal products are featured?
The page includes mechanical, cartridge, split, and welded metal bellows seals, plus supporting systems for rotating equipment.
What is a cartridge mechanical seal?
It is supplied as an assembled unit to simplify specified installation steps. The correct shaft, chamber, materials, and setup requirements still need verification.
When is a split mechanical seal useful?
It can reduce disassembly in suitable installations by fitting around the shaft. Check equipment dimensions, operating conditions, and access before selection.
What is a welded metal bellows seal?
It uses a welded bellows element as part of the seal design. Its suitability depends on the fluid, temperature, pressure, and required materials.
Can Flexaseal solutions be considered for mixers as well as pumps?
Yes, with an application-specific selection. Shaft motion, mounting orientation, pressure, and operating cycle can differ substantially from a pump installation.
Can a seal upgrade solve every leakage problem?
No. A different seal may help when correctly selected, but equipment condition and process behavior must also be addressed to achieve reliable service.
Why is my mechanical seal leaking?
Wear, dry running, unsuitable materials, shaft movement, or poor seal-support conditions may contribute. Record the fluid, temperature, pressure, and timing of the leak for diagnosis.
Why do replacement seals fail repeatedly?
The seal may be reacting to an unresolved pump or process problem. Inspect alignment, bearings, shaft condition, operating point, and seal-support arrangements.
What information is needed to select a seal?
Provide pump identification, shaft and chamber dimensions, fluid composition, temperature, pressure, and speed. Include solids, cleaning conditions, and the existing support system.
Why does seal-face material matter?
Faces must tolerate the fluid, lubrication conditions, heat, and any abrasive particles. Material selection should be reviewed with elastomers and metal components as one assembly.
What is the purpose of a seal-support system?
It provides the specified environment around the seal, such as cooling or a compatible supporting fluid. The arrangement must match the seal design and process conditions.
Can a mechanical seal be repaired?
Some seals can be restored after inspection, while damaged or unsuitable components require replacement. Repairability depends on the design, condition, and required performance.
Should the entire pump be inspected during seal replacement?
Yes, especially after repeated failures. Shaft movement, worn bearings, and hydraulic problems can damage a new seal even when the seal itself is correctly selected.
How often should seals be inspected?
Follow the equipment's maintenance plan and monitor leakage, temperature, vibration, and support-system condition. Set intervals around the service duty and consequences of failure.
How can I get local support for Flex-a-Seal Mechanical Seals?
Contact Process & Power at (901) 362-5500 with your location, equipment identification, and application or service concern. The team can review selection, parts, and service options for your needs.
What should I send when requesting a quote?
Include the required duty, fluid or process details, operating conditions, utilities, and installation dimensions. For existing equipment, add nameplate photos, model and serial numbers, and a description of the problem or planned change.
