Tapflo TX225 STT Double Diaphragm Pump

Applications & Use Cases

• Transfer of viscous food products such as sauces, jams, and purees.
• Handling shear-sensitive liquids like yoghurts and creams without degradation.
• Dosing and batching of ingredients in beverage production.
• Pumping pharmaceutical and cosmetic emulsions and suspensions.
• Unloading tanks and containers containing food-grade liquids.

Typical Specifications

Typical capacity

For this class of equipment, capacities commonly range from 50 to 250 litres per minute, depending on fluid viscosity and discharge pressure.

Power supply

These are air-operated double diaphragm (AODD) pumps, requiring a compressed air supply, typically 5 to 7 bar.

Materials of construction

Sanitary series pumps commonly feature stainless steel wetted parts (e.g., AISI 316) and food-grade diaphragms and valve balls (e.g., PTFE, EPDM, NBR).

Connections

Process connections are typically sanitary clamp (Tri-Clamp) or DIN 11851, commonly ranging from 1.5 to 3 inches.

Mounting

Units of this type are often supplied on a stainless steel frame for portability and stability within a processing environment.

Maximum particle size

AODD pumps can typically handle solids up to 10-15 mm, though this varies by pump size and valve design.

Frequently Asked Questions

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

  AODD pumps offer gentle product handling, self-priming capabilities, the ability to run dry without damage, and suitability for abrasive or viscous fluids. Their seal-less design also reduces leak points.

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

• What maintenance is typically required for a double diaphragm pump?

• Can this pump handle both thin and highly viscous liquids?

• What certifications should I look for with a sanitary pump?
