Quattroflow QF 1200-S Single-use Diaphragm Pump

• Sterile filtration and virus removal in biopharmaceutical production.
• Chromatography and tangential flow filtration (TFF) processes.
• Aseptic transfer of media, buffers, and drug products.
• Filling and dispensing operations for sensitive biological fluids.

Typical Flow Rate

For this model (QF 1200-S), flow rates commonly reach up to 1200 litres per hour.

Pump Type

Quaternary diaphragm pump, known for low shear and pulsation.

Control System

Units of this type commonly feature integrated controllers for automated operation and monitoring.

Wetted Materials

Single-use versions typically utilise polypropylene for fluid contact parts.

Power Supply

Units in this class commonly operate on standard industrial single-phase or three-phase electrical supplies, often 230V or 400V, with specific requirements depending on the motor and controller.

Integration

Typically designed for compatibility with various flow and pressure sensors for system integration.

• What are the primary 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, making them ideal for sterile applications.

• How does a quaternary diaphragm pump differ from a peristaltic pump?

• Is this pump suitable for handling viscous fluids?

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

• Can this pump be integrated into an existing automated process line?

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.
