Independent mechanical seal consultancy and supply. 36 years experience. Built on relationships that last decades.
Seal failures don't announce themselves. They build quietly, wrong material, wrong fit, wrong advice from someone who sold you the cheapest option. By the time there's a problem, the damage is already done. I work with engineering directors and plant managers who are done having that conversation.

Watch how we restore seals to like-new condition
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 find it, fix it and make sure it doesn't happen again.
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.
No sales process. No account manager. Just Andrew.

We converted packed glands into high-performance cartridge seals for thousands of Robuschi pumps. This retrofit improves seal life, reduces leakage, and installs with minimal downtime. Trusted by engineers across the UK, it's a fast, reliable upgrade for any Robuschi setup.
Most seal failures are not product failures. They are specification failures the wrong material for the chemistry, the wrong face combination for the abrasion level, the wrong flush plan for the operating temperature. When the same seal fails repeatedly in the same pump, the answer is rarely "buy a better seal." The answer is almost always a closer look at the actual operating conditions versus the original design intent.
Acumen Seals & Pumps was founded in 1999 on a simple principle: an independent specialist with no manufacturer loyalty will always give better advice than a distributor with a catalogue target. Andrew Sykes MCGI has applied that principle across 36 years, working to standards including API 682, DEF-STAN 02-337, NORSOK M710, and USP Class VI.
