Quattroflow QF 1200-S Single-use Diaphragm Pump

• Biopharmaceutical manufacturing for sensitive fluid transfer.
• Cell culture media and buffer transfer in sterile environments.
• Chromatography and tangential flow filtration (TFF) systems.
• Vaccine production and other sterile processing applications.

Typical capacity

For this class of equipment, flow rates commonly range up to approximately 1,200 LPH.

Power supply

Units typically require a standard industrial power supply, often 24V DC for the pump head drive.

Pump head type

This model utilises a single-use quaternary diaphragm pump head, designed for sterile applications.

Fluid compatibility

Suitable for sensitive biological fluids, shear-sensitive cells, and protein solutions.

Materials of construction (wetted parts)

Wetted parts are typically made from USP Class VI compliant plastics, such as polypropylene or polycarbonate, within the single-use pump head.

Control interface

Commonly integrates with external control systems via standard industrial communication protocols.

• What are the primary benefits of a single-use diaphragm pump like the QF 1200-S?

  Single-use pumps eliminate the need for cleaning validation and sterilisation between batches, reducing downtime and cross-contamination risks. They are particularly beneficial for sensitive and sterile bioprocessing applications.

• Is this pump suitable for shear-sensitive fluids?

• What maintenance is typically required for a used unit?

• Can this pump be integrated into existing bioprocessing lines?

• What is the typical lifespan of the single-use pump head?

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.
