There is no “FDA certified” stamp affixed to a pump body. When discussing “FDA-compliant pumps” for food or pharmaceutical contact applications, the term actually refers to two distinct concepts: FDA compliance — manufactured according to current Good Manufacturing Practice (cGMP) for safety, quality, and process control; and food-approved materials — materials in the product-contact wetted parts that have been evaluated by FDA or a recognized body as safe and non-leaching into the product. Understanding both concepts correctly is the critical step in avoiding common “compliance traps” when procuring pumps for the food, beverage, and pharmaceutical industries.
A pump serving food-contact industries must simultaneously satisfy two tiers of requirements: manufacturing process compliance with cGMP, and contact materials within an approved group. The following are the key technical benchmarks to verify before selecting a pump.
- 21 CFR Part 110 & 117 — the Good Manufacturing Practice (GMP/cGMP) framework that food-contact equipment must comply with.
- FSMA — the Food Safety Modernization Act, shifting the emphasis to preventive controls rather than incident response.
- Contact materials — stainless steel, PTFE, polypropylene (PP), PVC, FKM, EPDM, silicone, ceramic, and titanium are within the approved group.
- Recognized bodies — in addition to FDA, ANSI, NSF, and EU authorities evaluate food-approved equipment.
- Seal-less design — sealed-body magnetic drive centrifugal pumps, reducing leakage points and microbial accumulation sites.
How “FDA compliant” and “food-approved” Differ
Two Separate Tiers That Must Be Met Together
Many purchasing engineers mistakenly assume that a manufacturer’s “FDA” declaration is sufficient. In practice, FDA does not issue a single certificate for each individual pump. Instead, there are two distinct evaluation layers that equipment must satisfy when serving food and pharmaceutical contact industries.
- FDA compliance relates to process: the equipment is manufactured according to cGMP, ensuring consistency, traceability, and quality control in production.
- Food-approved relates to materials: product-contact wetted parts must use materials evaluated as safe and non-leaching by FDA or bodies such as ANSI, NSF, or EU authorities.
!A pump using approved materials but not manufactured to cGMP — or vice versa — may fail to meet the overall requirements of a food-contact line. Both tiers must be confirmed, not just one.
Regulatory Framework & Standards to Reference
21 CFR, FSMA, and Recognized Bodies
When evaluating a pump for the food, beverage, or pharmaceutical industry, the following regulatory benchmarks serve as the reference points rather than relying on generic supplier declarations.
| Reference Point | Description | Significance When Selecting a Pump |
|---|---|---|
| 21 CFR Part 110 | Good Manufacturing Practice (GMP) for food manufacturing, packaging, and storage | Foundation for sanitary equipment requirements in product-contact applications |
| 21 CFR Part 117 | Updated current Good Manufacturing Practice (cGMP) | Guides manufacturing process and equipment control requirements |
| FSMA | Food Safety Modernization Act | Shifts focus to preventive controls |
| ANSI / NSF / EU | Bodies that evaluate food-approved equipment | Independent assessment sources for contact material safety |
For the pharmaceutical industry, sanitation and traceability requirements are typically more stringent; refer to the pumps for the pharmaceutical industry solution page for additional criteria.
Selecting Materials for Product-Contact Parts
Food-Contact Approved Material Groups
The critical factor of a food-approved pump lies in the wetted parts materials — the components in direct contact with the pumped fluid. The following materials are within the group evaluated as safe for food-contact applications:
- Stainless steel & titanium — inert metals, sanitation-resistant, suitable for environments requiring mechanical durability.
- PTFE & polypropylene (PP) — chemically inert engineering plastics, minimizing leaching.
- PVC & ceramic — suitable for certain fluids; compatibility must be verified.
- FKM, EPDM, and silicone-based seals — elastomers approved for contact sealing components.
!Material compatibility depends on the pumped fluid, temperature, and concentration. It is advisable to consult the chemical compatibility chart for each specific application before finalizing a configuration, rather than assuming “any plastic will do.”
Sanitary Design: Why Seal-less Design Receives Attention
Seal-less, Magnetic Drive, and the Leakage Question
Beyond materials, pump construction also affects suitability for sanitary applications. Sealed-body magnetic drive centrifugal pumps (seal-less magnetic drive) eliminate mechanical seals — traditionally a leakage point and a site where fluid accumulates. The sealed-body design provides more controlled fluid transfer and reduces cross-contamination risk points.
- Elimination of mechanical seals: removes one leakage point and one potential microbial accumulation gap.
- Run-dry capability on certain models protects the pump during intermittent fluid supply.
- For drum/container decanting, drum pumps support smooth, hygienic, and controlled fluid transfer.
Depending on the line layout, different pump families will be appropriate for each position. Refer to the solution overview on the sanitary pumps for the F&B industry (hygienic) and pumps for the food and beverage industry pages.

Frequently Asked Questions
Is there an “FDA certified” certification for an individual pump?
+
There is no “FDA certified” stamp issued for individual pumps. Instead, equipment is evaluated on two tiers: FDA compliance (manufactured to cGMP) and food-approved contact materials. Both tiers must be confirmed rather than relying on a general certification declaration.
How do “FDA compliant” and “food-approved” differ?
+
FDA compliant refers to the manufacturing process under current Good Manufacturing Practice (cGMP). Food-approved refers to the materials in direct contact with the product — they must be evaluated as safe and non-leaching by FDA or bodies such as ANSI, NSF, or EU authorities.
Which regulations should be referenced for food-contact equipment?
+
Key reference points include 21 CFR Part 110 and Part 117 (Good Manufacturing Practice), the Food Safety Modernization Act (FSMA), and evaluations from recognized bodies such as ANSI, NSF, and EU authorities for food-approved equipment.
Which materials are approved for product-contact parts?
+
The group of materials evaluated as safe includes stainless steel, titanium, PTFE, polypropylene (PP), PVC, ceramic, and sealing elastomers such as FKM, EPDM, and silicone. Specific material selection still requires compatibility verification against the actual pumped fluid, temperature, and concentration.
Why do seal-less pumps receive attention in sanitary applications?
+
Sealed-body magnetic drive centrifugal pumps eliminate mechanical seals — traditionally a leakage point and a gap where fluid and microorganisms accumulate. The sealed-body design provides more controlled fluid transfer and reduces cross-contamination risk points in food-contact lines.
What pump families from Finish Thompson are suitable for food and pharmaceutical industries?
+
The families typically considered include air-operated diaphragm pumps (AODD), centrifugal pumps (including sealed-body magnetic drive variants), and drum pumps. Wetted-part material configurations are selected according to the specific pumped fluid to meet food-approved requirements.
