Aro double diaphragm pump

• 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.

• 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?

• What maintenance is typically required for an AODD pump?

• Can this pump handle solids?

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

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.
