Quattroflow QF 1200-S Single-use Diaphragm Pump

• Transfer of sensitive biological fluids in pharmaceutical and biotech manufacturing.
• Chromatography and tangential flow filtration (TFF) systems.
• Aseptic filling operations for sterile products.
• Media and buffer preparation in bioprocessing workflows.

Typical capacity

For this model class, flow rates typically range up to approximately 1,200 L/h.

Power supply

Units of this type commonly operate with a 24V DC power supply, requiring an external control unit.

Diaphragm type

Features a quaternary diaphragm design, characteristic of Quattroflow pumps for gentle fluid handling.

Fluid contact materials

Single-use wetted parts are typically constructed from USP Class VI compliant plastics, such as polypropylene or polycarbonate.

Sterilisation

Designed for single-use applications, eliminating the need for sterilisation-in-place (SIP) or clean-in-place (CIP) of the fluid path.

Pump head

Utilises a disposable pump head, which is replaced after each use or campaign.

• What are the main benefits of a single-use diaphragm pump like the QF 1200-S?

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

• Is this pump suitable for shear-sensitive fluids?

• What additional equipment is typically required to operate this pump?

• Can this unit be integrated into existing bioprocessing systems?

• What is the typical maintenance requirement for the QF 1200-S?

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.
