Aftermarket replacement, original-grade performance.
Application:
SD200 pump heads, Part No. A53465 (Drawing 0367-0600-1), operating on hydraulic oil duty — the kind of pump you find in marine loading systems and offshore transfer applications, running continuously under demanding conditions.
Working conditions matter here:
Hydraulic oil service means the seal sits in a closed pressure loop, cycling between load and idle through every loading/unloading cycle. Ambient salt spray, temperature swings, and long continuous running hours all add up — which is exactly why the original seal on this pump head needed a reliable second source.
Picture the setting:
a marine loading system where the pump is called on day and night, in salt air, moving hydraulic oil through pressure lines with no room for downtime. That's the duty this replacement was built for.
Our replacement:
We supplied a drop-in replacement seal dimensionally matched to the OEM drawing, manufactured in our ISO-compliant facility. Material combinations can be selected for the specific duty — SiC / TC / Viton among the options we build.
Why it works in this service:
✅ Dimensional match against the OEM spec — direct fit, no pump modification
✅ Material options matched to hydraulic oil duty and marine exposure
✅ Backed by 27+ years of seal manufacturing and field service experience If you run SD200 pump heads — or any hydraulic-oil duty seal that's hard to source — send us your part number and we'll come back with a proposal.
Backed by 27+ years of seal manufacturing experience and the same quality standards trusted by 1,000+ customers worldwide.
If you're running Framo SD200 pumps and looking for an alternative source — let's talk.
