6 ways to make fitting hydraulic seals easy.
When you fit hundreds of thousands of seals a year, you’re going to know all the tricks of the trade. At Sarum Hydraulics, the manufacturers of our stocked Micropac hand pumps, they’ve seen an awful lot of seals in their 30 years of trading. So, we asked the Directors, John Foster and Jon Robinson for their do’s and don’ts on fitting hydraulic seals.
“At the design stage, when you’re selecting the seals, think carefully. There are a massive number of hydraulic seals to choose from", says Engineering Director, John Foster." I try to design using standard generic sizes and not “specials.” Quite simply, if a seal is unique to one supplier, you have nowhere to turn if it is suddenly quoted on a 12 week lead time or it is quoted at five times the original price.”
This helps production Director Jon Robinson too, as he needs a small number of quality seal suppliers in his supply chain.
“We’re fans of DMR Seals on specialist hydraulic profiles or materials” he explains. “For O rings, we rate Eastern Seals and Barnwell Services pretty highly. With a massive range of available sizes and compounds all offered with recent cure dates, that is what we need. Nowadays, a seal stockist must eat, sleep and breathe seals in a big way rather than keeping just a few to complement other products. Go to a specialist. "
Before the do’s, let’s start with three big don’ts when dismantling hydraulics:

Finally, be organised if you are swapping out a leaking seal. Identify the job so that you can see what has been changed or not. Sarum Hydraulics will keep the defective seal until testing has taken place, just to help diagnostics if the problem then isn’t fixed.
