36 years in sealing · Supplied across the UK, Europe & Asia
See the mechanical seal refurbishment process. Acumen arranges refurbishment through specialist partners.
A seal failure is never just a seal. It's downtime. Contamination risk. An unplanned shutdown. A conversation with the MD that nobody wanted. If failures are becoming a pattern, the problem isn't bad luck, it's specification. I investigate the failure and check the mechanical seal specification before recommending a replacement.
Multiple suppliers. Inconsistent quality. Nobody who actually owns the problem. Most companies inherit this situation gradually and live with it because untangling it feels like more work than it's worth. It isn't. I've done it for clients across pharmaceutical, chemical processing, food and beverage and water treatment, usually paying for itself within months.
A sealing engineer with 36 years experience costs more than most businesses want on the payroll. As an independent consultant I give you that knowledge when you need it, without the overhead. Retained, project-based or fractional, structured around what actually works for your business.
Most of my customers have been with me for 26 years.
In this industry, that's not sentiment. That's a performance record.
36 years. Hundreds of applications. Thousands of seals. Zero tolerance for failures that were preventable.
If your seals are failing, your supply chain is a mess, or you just want to talk to someone who actually knows this sector, call me directly.
I started Acumen in 1999 with no family money behind me and no audience. Four ordinary habits kept it going.
Mine is mechanical seals. Not everything with a pump attached.
You see the quote. You never see the reading behind it.
A price you cannot explain is a price you will end up discounting.
36 years is mostly ordinary Tuesdays.

Selected for your duty: replacements and new designs.
Cartridge seals, component mechanical seals and bellows seals for pumps and rotating equipment. Replacing a seal: send the pump make and model, seal dimensions, fluid and operating conditions. New design or OEM: send the drawing or duty. We check the specification and confirm price and lead time before you order.

Seal failing repeatedly and nobody knows why? New application to specify? Need an independent view before committing to a supplier? 36 years in sealing. We check the failure mode and specification before recommending a mechanical seal. Consultancy scope and fees are agreed before work starts.
"A level of product knowledge and industry credibility that is genuinely difficult to find at Divisional Director level." — Morgan Burgoyne, President, AFC Europe Limited

A cartridge mechanical seal can replace gland packing on suitable Robuschi pumps. We check the stuffing box, shaft condition, fluid and operating duty before recommending a conversion. See the conversion example and send your pump details for a suitability check.
Companies also bring me in to train their teams - teaching what 36 years in process plants taught me.
See the training coursesWhen you work with me, you get 36 years of sealing experience, not someone reading from a catalogue. I have worked with some manufacturers and distributors for more than 20 years, and they have earned my loyalty because their products and their people have stood up to the work.
But I do not work to a catalogue target. If a lower-cost option does the job, I will say so. I only work closely with a limited number of companies, chosen for the product, the people behind it and how they respond when something goes wrong. A manufacturer can retain me for my judgement, not to buy my recommendation.
Mechanical seals are what we do.
We select and supply cartridge, component and double mechanical seals for pumps and other rotating equipment on chemical plants and industrial sites.
We take on repeat failures, obsolete seals and the applications that need a fresh approach. Where the parts are worth saving, we manage refurbishment. For demanding duties, we match the FFKM grade to the real conditions, never a blanket upgrade.
For manufacturers and distributors, we work on product development and new business for seal products.

Learn More About Our Mission→From offshore oil rigs to sterile pharma lines, we engineer sealing solutions that survive the conditions others can't.
Acumen Seals & Pumps supplies cartridge seals, component mechanical seals and bellows seals for pumps and rotating equipment. Andrew Sykes MCGI checks the pump details and operating duty before recommending a replacement.
Send the pump make and model, clear photographs, seal dimensions, fluid, temperature, pressure and shaft speed where known. If the original seal cannot be identified, start with the measurement guide. For a damaged seal, refurbishment is considered after inspection. Material selection depends on the operating conditions, not the part number alone.
