UK-Made Mechanical Seals for Your Equipment
Reliable seals, designed, built and repaired in the UK to keep your pumps, mixers and rotating equipment running smoothly.
About Us
We design, manufacture and refurbish mechanical seals
Over 45 years of engineering experience
RB Mechanical Seals has been supplying, building and refurbishing mechanical seals for more than 45 years. The business was originally focused on the pharmaceutical and chemical sectors, where tolerances are tight, processes are unforgiving and failure is not an option.
Working in these demanding industries shaped the way we engineer today. Accuracy, stability and consistent performance became the standard, not the goal.
A business built on real engineering
Ben has worked in the business for 25 years and took over the company a decade ago. Under his leadership, we used the experience gained in pharmaceutical and chemical processing and applied it to other industries where equipment runs under equally tough conditions.
Agriculture, biogas, wastewater, food production, brewing and dairy all benefited from the standards we developed in regulated, high-risk environments.
The result was a complete shift in how operators approach sealing. Instead of accepting constant failures, poor performance and premature wear, they now get seals engineered properly for the duty, not just for the catalogue.
What we do
We design, manufacture and refurbish mechanical seals for pumps, mixers and agitators across a wide range of industries.
We also rebuild the equipment itself, restoring pumps and mixers to efficient, reliable running condition. Many refurbishments cost around half the price of new equipment and often deliver better performance than the machine achieved in its later life.
Built for real operating conditions
We do not design seals based on perfect test environments. We design them for the conditions our customers actually face.
Slurry, digestate, fibrous media, chemicals, powders, fats, sugar, grit, solvents, thermal shock, misalignment and vibration all affect seal behaviour.
Our job is to build sealing solutions that manage these realities rather than fail the moment conditions drift away from ideal.
Straight, practical advice
We tell you plainly whether refurbishment or replacement is the best option. If a pump can be rebuilt, we will rebuild it. If a seal is beyond saving or the duty has changed, we will say so. You get advice based on engineering sense, not on selling parts.
ATEX and compliance
Where equipment operates in hazardous zones, we manufacture seals to ATEX Category 2 for Zone 1 and Zone 21.
You get a compliant, reliable sealing solution built for safety.
Contact UsWhy customers rely on us
Operators trust us because our seals last longer, run cooler and cope with the real conditions that standard designs cannot handle.
Our refurbishment work reduces costs, extends asset life and cuts unplanned downtime. Most importantly, we fix the actual cause of failures instead of masking the symptoms.
