Pumps for pumping ketchup out of drums

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:


1. Sanitary Rotary Lobe Pump (Best for High-Volume Transfer)

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


2. Sanitary Piston Pump (For Precision Filling/Portioning)

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


3. Progressive Cavity Pump (For Ultra-Thick Ketchup)

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


4. Sanitary Peristaltic Pump (For Small Batches or Sensitive Ketchup)

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

  • Verderflex


Key Selection Criteria

✔ 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).


Accessories for Ketchup Pumping

  • Drum unloader kit (tilting stand for full evacuation).

  • Heated hoses (if ketchup is refrigerated/thickened).

  • Sanitary tri-clamp fittings (quick disassembly).


Avoid These Pumps for Ketchup

❌ Centrifugal pumps – Can’t handle viscosity, may aerate.
❌ Gear pumps – Risk of squeezing out oils, causing separation.


Top Maintenance Tips

  • 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.
