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?

Yes, Quattroflow pumps are designed for continuous operation in demanding industrial and laboratory environments, offering reliability and consistent performance over extended periods.

What kind of maintenance does a QF150 typically require?

Maintenance is generally low, focusing on periodic inspection and replacement of diaphragms and seals. The pump head design often allows for easy access and sterile component changes.

Can this pump handle abrasive media?

While primarily designed for sensitive fluids, the gentle pumping action and material choices can allow it to handle some suspensions with abrasive particles, but buyers should confirm specific suitability with the seller.

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

For pharmaceutical applications, units commonly comply with cGMP guidelines and may have certifications such as USP Class VI for wetted materials, and often meet FDA requirements.

This listing is for a QuattroFlow QF150 Diaphragm Pump.

The unit is in full working condition and is ready for immediate release.

The Quattroflow 150S is a 4-piston Diaphragm pump, which is mainly used to pump water-like fluids

that are typically handled in research-, pilot plant- or production facilities of the pharmaceutical, biotech,

food or cosmetic research centres or plants.

Examples:

• Solutions containing proteins (albumin, IgG, Clotting factors, monoclonal antibodies, enzymes,

vaccines.)

• Solutions of polymers or suspensions (silicon, latex, chromatography media)

• Cell suspensions (bacteria, yeast, algae, fungi, mammalian cells)

• colloidal solutions

• Suspensions of viruses or phage

• Dairy products

• Gelatine

• Supplements and ingredients for cosmetic and food

Typical context for this category of equipment. Always confirm specifics with the seller.

Applications & Use Cases

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 Specifications

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.
