QuattroFLow QF15SU-U Single-use Diaphragm Pump

• Biopharmaceutical manufacturing for sensitive fluid transfer.
• Chromatography and tangential flow filtration (TFF) systems.
• Vaccine production and cell culture media handling.
• Buffer and media preparation in sterile environments.

Typical capacity

For this class of equipment, flow rates commonly range from 1 to 15 litres per minute.

Power supply

Units of this type typically operate on standard industrial single-phase or three-phase power, often 230V or 400V.

Diaphragm type

Features quaternary diaphragm technology for gentle fluid handling.

Fluid path

Designed for single-use fluid paths, eliminating the need for sterilisation between batches.

Pressure range

Commonly capable of discharge pressures up to 4 bar.

Footprint

Typically compact, suitable for integration into existing bioprocessing skids or benchtop use.

• What are the main benefits of a single-use diaphragm pump?

  Single-use pumps eliminate cross-contamination risks, reduce cleaning validation efforts, and minimise downtime associated with sterilisation processes.

• Is this pump suitable for shear-sensitive fluids?

• What kind of maintenance does a used single-use pump require?

• Can this pump be integrated into automated systems?

• What are the typical applications for a QF15SU-U?

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.
