QuattroFlow QF150 Diaphragm Pump

• Transfer of sensitive biological fluids in biopharmaceutical manufacturing.
• Handling of sterile media and buffers in upstream and downstream processing.
• Single-use fluid path applications to minimise cross-contamination risks.
• Precise dosing and metering in laboratory and pilot-scale operations.

Typical flow rate

Units in this series typically offer flow rates suitable for laboratory to small-scale production, often up to 150 L/h.

Operating pressure

Commonly operates within a pressure range appropriate for biopharmaceutical fluid transfer, typically up to 6 bar.

Diaphragm material

Often features USP Class VI compliant materials like EPDM or PTFE for critical applications.

Power supply

Typically requires a standard electrical supply, commonly 230V, 50Hz for UK operation, with low power consumption.

Connectivity

Units of this type commonly feature sanitary connections such as Tri-Clamp or hose barb fittings.

Control interface

Often includes a local control panel or can be integrated into a larger process control system.

• What makes a quaternary diaphragm pump suitable for biopharma?

  Quaternary diaphragm pumps offer gentle, pulsation-free fluid transfer, which is crucial for shear-sensitive biological products. They also provide precise flow control and excellent containment.

• Can this pump handle abrasive fluids?

• Is this unit suitable for cleanroom environments?

• What maintenance is typically required for a used unit?

• Are spare parts readily available for QuattroFlow QF150 pumps?

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.
