Hygienic single seals
Electropolished single seals in USP Class VI materials with ASME BPE finishes for high-purity pumps.
GMP, FDA and USP Class VI-aligned shaft seals for hygienic and high-purity pumps — ASME BPE surface finishes, supplied to spec.
At a glance
We are the manufacturer, not a reseller — so we match the seal to the duty, build it in-house, and supply it at quantities that work for a distributor, an OEM or a maintenance department. Below is how we approach pharmaceutical pump sealing.
Purity is the product — WFI and high-purity media can’t pick up anything from the seal, so materials and finish are documented and traceable.
GMP wants surface finish — ASME BPE electropolished faces and housings that clean completely and pass audit.
CIP and SIP every batch — the seal sees hot WFI, caustic and steam repeatedly without shedding particles.
Aseptic duty may need a double seal with a sterile barrier to protect the product from the outside.
Range
From off-the-shelf replacements to fully engineered custom seals — at the quantities your operation actually orders.
Electropolished single seals in USP Class VI materials with ASME BPE finishes for high-purity pumps.
Double seals with a sterile barrier fluid for aseptic and contained processing.
Material certs and traceability, machined to your pump’s BPE standard or from a sample.
The right face pair and secondary are set by the media and the conditions — not by what a catalogue stocks. The table is a starting point; send us the duty and we confirm it.
| Service | Face pair | Elastomer | Why it matters |
|---|---|---|---|
| WFI / purified water | Silicon carbide / Carbon | USP Class VI EPDM | No leachables into high-purity water |
| CIP / SIP | Silicon carbide / SiC | FKM / USP EPDM | Repeated hot caustic and steam |
| Aseptic process | SiC / SiC, double | USP Class VI | Sterile barrier protects the product |
| High-purity solvents | SiC / SiC | FFKM | Solvent resistance at purity |
Pharmaceutical seals are specified on materials, finish and documentation — USP Class VI elastomers and ASME BPE surface finishes, with certs to match.

FAQ
FDA-compliant and USP Class VI materials, ASME BPE surface finishes, and full material traceability for GMP. Aseptic duty may add a sterile-barrier double seal.
A smooth, electropolished surface cleans completely and won’t harbour or shed particles — which is what a GMP audit and a high-purity process require.
Yes — material certificates and traceability to support qualification, alongside the right USP Class VI elastomers and BPE finishes.
