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 food & beverage pump sealing.

CIP / SIPseals that survive daily clean and steam cycles
Crevice-freehygienic geometry that won’t harbour product
Why hygienic sealing is different
It has to be cleanable — crevices that trap product fail audits; hygienic seal geometry is non-negotiable.
CIP and SIP cycles hit the seal with hot caustic, acid and steam every day — the elastomer has to take all three.
Sticky and high-sugar media crystallize on the faces; a flush or quench keeps them clean.
Materials must be FDA-compliant — the face, the rubber and any flush all touch product.
Range
What we supply
From off-the-shelf replacements to fully engineered custom seals — at the quantities your operation actually orders.
Hygienic cartridge seals
Pre-set cartridge seals that drop in without on-site measurement — ideal for fast, clean changeovers.
Custom & OEM-compatible
Machined to your pump’s hygienic standard or reverse-engineered from a sample for legacy units.
Match the seal to the duty
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 |
|---|---|---|---|
| Hygienic process | Silicon carbide / Carbon | EPDM (FDA) | Clean, food-contact, cleanable |
| CIP / SIP high-temp | Silicon carbide / SiC | EPDM / FKM | Survives hot caustic, acid, steam |
| Sugar / sticky media | SiC / SiC, flushed | EPDM | A quench keeps faces from crystallizing |
| Dairy | SiC / Carbon | EPDM (FDA) | Gentle, cleanable, food-safe |
EPDM is the food-and-beverage default — it takes CIP/SIP chemistry where Nitrile fails. FDA-grade faces and elastomers are required wherever the seal touches product.

FAQ
Food & Beverage Pump Seal FAQ
What makes a seal “sanitary”?
Crevice-free geometry that cleans in place, FDA-compliant face and elastomer materials, and a finish that won’t harbour product. 3-A and EHEDG set the bar.
Which elastomer survives CIP/SIP?
EPDM handles the hot caustic, acid and steam of clean-in-place and sterilize-in-place cycles. Nitrile degrades fast under that chemistry.
Can you supply FDA-compliant seals at volume?
Yes — sanitary single and cartridge seals in FDA-grade materials, supplied to dairies, breweries and processors at distributor scale.
