QuattroFLow QF15SU-U Single-use Diaphragm Pump

• Biopharmaceutical processing, particularly for shear-sensitive fluids like proteins and enzymes.
• Laboratory and pilot plant environments requiring precise and contamination-free fluid transfer.
• Aseptic filling and filtration systems in pharmaceutical manufacturing.
• Cell culture media transfer and buffer preparation.
• Vaccine production and other sterile fluid handling processes.

Typical flow rate

Units in this class commonly offer flow rates ranging from a few litres per hour up to approximately 100-200 litres per hour, depending on the specific model and application.

Operating pressure

Typically designed for low to medium pressure applications, often up to 4-6 bar.

Power supply

Commonly operates on standard industrial single-phase or three-phase power, often 230V or 400V, with a frequency of 50Hz for the UK market.

Pump chamber material

For single-use models, the wetted parts are typically constructed from biocompatible plastics such as polypropylene or polyethylene.

Footprint

These pumps are generally compact, suitable for integration into skids or laboratory benches, with dimensions typically under 50cm in any direction for the pump head.

Temperature range

Typically designed for fluid temperatures between 2°C and 50°C, suitable for most biopharmaceutical processes.

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

  Single-use pumps eliminate the need for cleaning validation and sterilisation between batches, significantly reducing downtime and the risk of cross-contamination. This is particularly beneficial in biopharmaceutical applications.

• How does the 4-piston diaphragm design improve fluid transfer?

• Can this pump handle viscous fluids?

• What maintenance is typically required for this type of pump?

• Is this pump suitable for sterile environments?

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.
