QuattroFlow QF15PTIU Single-use Pump Diaphragm Pump

• Precision fluid transfer in biopharmaceutical manufacturing.
• Chromatography and tangential flow filtration (TFF) systems.
• Buffer and media preparation and delivery.
• Vaccine and plasma fractionation processes.
• Sterile filling line integration.

Typical flow rate

Units in this class commonly offer flow rates suitable for laboratory to pilot-scale bioprocessing, typically ranging from a few millilitres to several litres per minute.

Diaphragm type

This model utilises a single-use quaternary diaphragm, designed for aseptic fluid handling and minimal shear.

Wetted materials

For single-use pumps, wetted parts are typically made from validated biocompatible plastics, such as USP Class VI certified polypropylene or similar polymers.

Operating pressure

Units of this type are generally designed for low to moderate pressure applications, common in bioprocessing, typically up to a few bar.

Footprint

The QF15PTIU is described as compact, suggesting it is suitable for integration into existing skids or benchtop use, with dimensions commonly found in small-scale bioprocess equipment.

Power supply

Typically requires a standard industrial power supply, often 24V DC when integrated with a control unit, or a specific AC voltage depending on the drive motor.

Sterilisation

As a single-use pump, the fluid path is typically gamma-irradiated or sterilised by other validated methods prior to use, eliminating the need for in-situ sterilisation.

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

  Single-use pumps eliminate the need for cleaning validation, reduce the risk of cross-contamination, and minimise downtime between batches, offering significant operational efficiencies in biopharmaceutical settings.

• Is this pump suitable for shear-sensitive fluids?

• What maintenance is required for a used single-use pump?

• Can this pump be integrated into automated systems?

• What accessories are typically needed for operation?

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.
