What Is a Double Diaphragm Milk Pump?
A double diaphragm pump—also known as an AODD (air-operated double diaphragm) pump—uses two flexible diaphragms that move back and forth, creating a vacuum that draws in and pushes out liquid.
For milk applications, these pumps are constructed with:
- Food-grade elastomers (FDA-compliant)
- 316L stainless steel wetted parts
- Smooth internal geometries to avoid bacterial buildup
- CIP/SIP compatibility for hygienic cleaning
The result is a pump that safely handles milk, cream, and similar dairy fluids—without damaging product consistency or risking contamination.
Why Use a Double Diaphragm Pump for Milk?
Milk is a delicate product. It can spoil, separate, or curdle if pumped incorrectly. Here’s why a double diaphragm milk pump is the ideal choice for many dairy operations:
✅ Gentle Handling – The low-shear, pulsation-free action preserves milk’s natural composition.
✅ Self-Priming & Dry Run Capable – No damage if the line runs dry or needs to be primed from a tank or tote.
✅ Sanitary Design – Internal surfaces are smooth and crevice-free for easy cleaning and compliance.
✅ Portable & Versatile – Can be easily moved between processing stations, tank unloading zones, or CIP lines.
✅ Air-Operated – No electrical motor needed—safe for wet environments and washdown areas.
Common Applications
Double diaphragm pumps are used in milk processing facilities for:
- 🥛 Raw Milk Transfer – From tankers to holding silos
- 🍶 Cream & Skim Milk Handling – Low-foam and gentle fluid movement
- 🧴 Milk Packaging Lines – Controlled transfer to filling machines
- 🧊 Chilled Dairy Transfer – Maintains temperature and integrity
- 🧽 Cleaning Fluids & CIP Solutions – Dual-use for plant sanitation
At MultiTorque, we supply dairy-ready diaphragm pumps tailored for these exact roles.
