What are the main advantages of a double diaphragm pump for food processing?

Double diaphragm pumps offer gentle product handling, preventing damage to shear-sensitive materials and suspended solids. They are also easy to clean in place (CIP) and can handle a wide range of viscosities.

Is this pump suitable for abrasive products?

While generally robust, the suitability for highly abrasive products depends on the specific diaphragm and valve material selection. Buyers should confirm with the seller for specific applications.

What kind of air supply is needed to operate this pump?

A clean, dry, and regulated compressed air supply is required. The exact pressure and flow rate needed will depend on the desired pump performance and product characteristics.

Can this pump run dry without damage?

Yes, a key advantage of air-operated double diaphragm pumps is their ability to run dry without sustaining damage, which is beneficial in many process applications.

What certifications are typically associated with pumps of this type for food use?

For food processing, units of this type commonly meet hygienic design standards such as 3-A Sanitary Standards and potentially CE marking for European markets.

Typical context for this category of equipment. Always confirm specifics with the seller.

Applications & Use Cases

Transferring fruit juices, concentrates, and other beverages.
Pumping viscous food products such as tomato paste, ketchup, and purees.
Handling dairy products including yogurt, cottage cheese, and liquid eggs.
Moving shear-sensitive products or liquids with suspended solids without damage.
Applications requiring hygienic transfer and easy Clean-In-Place (CIP) capabilities.

Typical Specifications

Typical flow rate: For this class of pump, flow rates commonly range from 100 to 500 litres per minute, depending on product viscosity and discharge pressure.
Inlet/Outlet size: Units of this type typically feature 3-inch (DN80) connections, suitable for high-volume transfer.
Operating pressure: Maximum operating pressures commonly found on units of this type are up to 7 bar (100 psi).
Power supply: These pumps are typically air-operated, requiring a compressed air supply, not electrical power.
Construction materials: Wetted parts are commonly constructed from hygienic materials such as 316L stainless steel and food-grade elastomers for diaphragms and valves.
Maintenance requirements: Double diaphragm pumps are known for relatively low maintenance, primarily involving periodic inspection and replacement of diaphragms and valve balls.
Suitable product characteristics: Ideal for products with high viscosity, shear sensitivity, and those containing soft suspended solids.
