What types of products are these pumps suitable for?

Sandpiper AODD pumps are well-suited for a wide range of food products, including those with high viscosity, solids content, or shear sensitivity, due to their gentle pumping action.

Are these pumps easy to clean?

Many AODD pumps designed for food use feature sanitary designs, making them suitable for Clean-in-Place (CIP) processes. The open design on a mobile stand can also aid manual cleaning.

What maintenance is typically required?

Routine maintenance typically involves checking diaphragms, balls, and seats for wear, and ensuring the air valve operates correctly. These components are generally replaceable.

Can this pump handle solids?

Yes, AODD pumps are known for their ability to handle solids in suspension without damage, making them suitable for products like fruit pulps or vegetable slurries. The maximum solid size will depend on the pump model.

What are the advantages of an air-operated double diaphragm pump over other pump types for food processing?

Advantages include self-priming capabilities, dry-run capability without damage, gentle product handling, and suitability for abrasive or corrosive fluids. They also offer variable flow control via air pressure adjustment.

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 such as fruit purees or yoghurts.
Dosing ingredients in batch processing operations.
Pumping abrasive fluids like those containing food particles or sugar crystals.
Use in clean-in-place (CIP) systems for chemical circulation.

Typical capacity: For this class of equipment, flow rates commonly range from 50 to 800 litres per minute, depending on the model and application.
Power supply: Air-operated double diaphragm (AODD) pumps are powered by compressed air, typically requiring 2 to 7 bar (30-100 psi) air pressure.
Materials of construction: Wetted parts are commonly available in food-grade materials such as stainless steel (316L), polypropylene, or PVDF, with diaphragms and check valves in PTFE, Santoprene, or Buna-N.
Port sizes: Commonly found with inlet/outlet ports ranging from 1 to 3 inches, suitable for various line sizes in food processing.
Mobility: Units like this are often mounted on stainless steel mobile stands, facilitating easy movement between processing areas.
Certifications: For food applications, units typically comply with FDA regulations and may hold ATEX certification for hazardous environments, if applicable.

Sandpiper AODD pumps are well-suited for a wide range of food products, including those with high viscosity, solids content, or shear sensitivity, due to their gentle pumping action.

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.
