QuattroFlow QF150 Diaphragm Pump

• Handling sensitive biological solutions such as proteins, antibodies, and vaccines in pharmaceutical and biotech research and production.
• Transferring cell suspensions including bacteria, yeast, and mammalian cells without causing damage.
• Pumping colloidal solutions, suspensions of viruses, or phage in laboratory and pilot plant settings.
• Processing dairy products, gelatine, and various supplements and ingredients in food and cosmetic industries.
• Managing chromatography media and other viscous or shear-sensitive fluids.

Typical flow rate

For this class of equipment, flow rates commonly range from a few litres per hour up to approximately 150 litres per hour, depending on the eccentric shaft setting.

Operating pressure

Units of this type typically operate at pressures suitable for sensitive fluid transfer, often up to 4-6 bar.

Fluid temperature range

Commonly, these pumps can handle fluid temperatures up to 80-90°C, with higher temperatures possible for CIP/SIP cycles.

Wetted materials

Product-wetted surfaces are typically made from biocompatible materials such as stainless steel (e.g., 316L) and medical-grade elastomers to ensure product integrity and hygiene.

Motor type

Often equipped with a brushless DC motor or similar, allowing for precise speed control and consistent flow.

Power supply

Typically requires a standard industrial power supply, commonly 230V single-phase or 400V three-phase, with appropriate frequency for UK operations.

Cleaning compatibility

Units are commonly designed for Clean-in-Place (CIP) and Sterilise-in-Place (SIP) processes, crucial for pharmaceutical and food applications.

• What is the primary advantage of a diaphragm pump over a peristaltic pump for sensitive fluids?

  While both are gentle, diaphragm pumps like the Quattroflow QF150 offer a pulsatile flow with minimal shear, making them highly suitable for very sensitive biological materials such as cells and proteins, often with higher flow rates and pressures than typical peristaltic pumps.

• Is this pump suitable for continuous operation?

• What kind of maintenance does a QF150 typically require?

• Can this pump handle abrasive media?

• What certifications are typically associated with this type of pump for pharmaceutical use?

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.
