What are the main advantages of an AODD pump for food processing?

AODD pumps offer gentle product handling, are self-priming, can run dry without damage, and are suitable for abrasive or viscous fluids. They also provide good containment for hazardous or sensitive products.

Is this pump suitable for CIP (Clean-in-Place) applications?

Many AODD pumps, particularly those with appropriate material construction, are suitable for CIP applications, handling cleaning solutions and sanitizers. Buyers should confirm specific material compatibility with the seller.

What maintenance is typically required for an AODD pump?

Routine maintenance typically involves checking and replacing diaphragms, balls, and seats as they wear. The air valve assembly may also require periodic inspection and servicing.

Can this pump handle solids?

AODD pumps are generally good at handling suspended solids and slurries due to their valving design and gentle action. The maximum solid size will depend on the pump's porting and internal clearances.

What certifications might be relevant for a used food-grade pump?

For food processing, certifications such as FDA compliance for wetted materials or ATEX for hazardous environments might be relevant. Buyers should confirm any existing certifications or compliance with the seller.

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

Transferring viscous liquids and slurries in food production.
Handling shear-sensitive products like yoghurts and fruit purees.
Pumping ingredients such as sauces, oils, and flavourings.
Emptying containers and IBCs of food-grade liquids.
Use in Clean-in-Place (CIP) systems for chemical transfer.

Typical capacity: For this class of equipment, capacities commonly range from 50 to 800 litres per minute, depending on the specific model and air supply.
Power supply: These are air-operated double diaphragm (AODD) pumps, typically requiring a compressed air supply, commonly between 2 to 7 bar (30-100 psi).
Materials of construction: Wetted parts are commonly available in food-grade materials such as stainless steel (316L), polypropylene, or PVDF, with diaphragms in PTFE, Santoprene, or Hytrel.
Port sizes: Inlet and outlet ports typically range from 1/2 inch to 3 inches, suitable for various flow rates and product viscosities.
Mobility: This unit is mounted on a stainless mobile stand, offering flexibility for use in different areas of a facility.
Pressure capability: AODD pumps can typically achieve discharge pressures up to the supplied air pressure, commonly around 7 bar.

AODD pumps offer gentle product handling, are self-priming, can run dry without damage, and are suitable for abrasive or viscous fluids. They also provide good containment for hazardous or sensitive products.

Diaphragm pumps are generally valued for their reliability and versatility across laboratory and pharmaceutical applications. Buyers typically prioritise condition of the diaphragm itself, seals and valve integrity when purchasing used units. Industry sentiment favours their gentle handling of sensitive fluids, low maintenance requirements and ability to manage viscous or abrasive media. Common strengths include self-priming capability, compact design and suitability for both suction and discharge applications. Durability remains a key selling point.
