For pumping ketchup (a thick, viscous, and often shear-sensitive product) out of 55-gallon drums, you need a sanitary, high-viscosity pump that can handle its texture without separation or damage. Here are the best options:
Why?
Handles thick, pulpy ketchup smoothly (low shear).
FDA-compliant, 3-A certified (hygienic for food use).
Easy to clean (CIP/SIP compatible).
Key Features:
Stainless steel (316L) or polished surfaces.
Gentle pumping action (preserves texture).
Flow rate: ~5–50 GPM (adjustable).
Top Brands:
Alfa Laval
SPX FLOW (Waukesha)
Fristam
Why?
High-pressure capability (for thick ketchup).
Accurate dosing (good for packaging lines).
Key Features:
PTFE seals (resists acids in ketchup).
Pulsation dampener (for smooth flow).
Best For:
Factories filling bottles/tubs.
Brands:
Waukesha Cherry-Burrell
GEA
Why?
Handles extreme viscosity without separation.
Self-priming & gentle (good for sticky products).
Key Features:
Stator (rubber) resists abrasion from tomato solids.
Flow rate: ~1–20 GPM.
Brands:
Moyno
Seepex
Why?
Zero contamination risk (only the tube touches product).
Reversible flow (helps clean drum completely).
Limitations:
Slower than lobe/piston pumps.
Best For:
Craft producers, small-scale operations.
Brands:
Watson-Marlow

✔ Viscosity Handling – Ketchup ranges from 5,000–50,000 cP (thicker than syrup).
✔ Material – 316L stainless steel, FDA elastomers (EPDM, PTFE).
✔ Cleaning – Must be CIP/SIP capable (avoid bacterial growth).
✔ Shear Sensitivity – Avoid centrifugal pumps (can break down texture).
Drum unloader kit (tilting stand for full evacuation).
Heated hoses (if ketchup is refrigerated/thickened).
Sanitary tri-clamp fittings (quick disassembly).
❌ Centrifugal pumps – Can’t handle viscosity, may aerate.
❌ Gear pumps – Risk of squeezing out oils, causing separation.
Flush with warm water immediately after use (prevents drying/clogging).
Inspect seals regularly (ketchup’s acidity can degrade some materials).
Use food-grade lubricants if needed.
