Quattroflow QS15SU Fluid Systems Pump

• Biopharmaceutical manufacturing for sterile fluid transfer.
• Chromatography and tangential flow filtration (TFF) systems.
• Aseptic media and buffer preparation.
• Vaccine production and cell culture processes.
• Single-use fluid management in critical process steps.

Typical flow rate

For this class of pump, flow rates typically range from a few litres per minute up to approximately 20-30 litres per minute, depending on the specific configuration and back pressure.

Operating pressure

Units of this type commonly operate at pressures up to 4-6 bar (60-90 psi).

Power supply

Typically requires a low-voltage DC power supply, often 24V DC, integrated into a control system.

Diaphragm type

Features quaternary diaphragm technology, designed for gentle product handling and low pulsation.

Material contact parts

For single-use models, wetted parts are typically made from USP Class VI certified plastics, such as polypropylene or polycarbonate.

Footprint

Compact design, commonly found on units of this type, suitable for integration into skids or benchtop setups.

• What does 'single-use' mean for this pump?

  Single-use means the fluid path components that contact the product are disposable. This eliminates the need for cleaning and sterilisation validation between batches, reducing downtime and cross-contamination risks.

• Is this pump suitable for shear-sensitive fluids?

• What maintenance is typically required for a QS15SU?

• Can this pump handle abrasive media?

• What certifications are relevant for this type of equipment in biopharma?

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.
