Quattro Fluid SystemFlow 1000S quaternary diaphragm positive‑displacement pump

• Biopharmaceutical manufacturing for gentle cell suspension transfer.
• Chromatography and tangential flow filtration (TFF) systems requiring precise flow.
• Transfer of shear-sensitive proteins, vaccines, and blood products.
• Single-use bioprocessing applications where sterility and minimal cross-contamination are critical.

Typical flow rate

For this class of quaternary diaphragm pump, flow rates typically range from low to moderate, suitable for laboratory to pilot-scale bioprocessing.

Operating pressure

Units of this type commonly operate at pressures appropriate for biopharmaceutical fluid transfer, typically up to a few bar.

Diaphragm material

Diaphragms are typically made from biocompatible materials such as EPDM or PTFE, ensuring chemical compatibility and gentle product handling.

Wetted parts material

Wetted parts are commonly constructed from materials like polypropylene or stainless steel, suitable for pharmaceutical contact.

Power supply

Electrically driven, typically requiring a standard industrial single-phase or three-phase supply, commonly 230V or 400V, 50Hz in the UK.

Control interface

Often includes integrated control options for flow rate adjustment and system integration, commonly via a local display or remote PLC connection.

• What are the key benefits of a quaternary diaphragm pump for biopharma?

  Quaternary diaphragm pumps offer extremely gentle, low-shear pumping action, which is crucial for maintaining the integrity of sensitive biological products. They also provide precise flow control and are often designed for single-use applications.

• Is this pump suitable for sterile applications?

• What kind of maintenance does a pump like this typically require?

• Can this pump handle abrasive fluids?

• What is the typical footprint of a SystemFlow 1000S?

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.
