Quattroflow QS15SU Fluid Systems Pump

• Transfer of sensitive biological fluids in pharmaceutical and biotech research and production.
• Handling of cell suspensions and colloidal solutions in laboratory and pilot plant settings.
• Pumping of dairy products and other food ingredients requiring gentle handling.
• Processing of cosmetic solutions and suspensions.
• Use in various research and development facilities for fluid transfer.

Pump Type

Typically a 4-piston diaphragm pump, designed for gentle fluid transfer.

Typical Capacity

For this class of equipment, flow rates commonly range from a few litres per hour up to approximately 20-30 litres per hour, depending on the specific model and application.

Power Supply

Units of this type commonly operate on standard industrial single-phase or three-phase power, typically 230V or 400V, 50Hz, with appropriate motor ratings.

Wetted Materials

Commonly features wetted parts made from biocompatible materials such as stainless steel (e.g., 316L) and USP Class VI polymers, suitable for pharmaceutical and food contact.

Pressure Capability

Typically designed for low to medium pressure applications, often up to 4-6 bar, suitable for gentle transfer without high shear.

Footprint

For this class of pump, the footprint is generally compact, suitable for benchtop or integration into skid-mounted systems.

Maintenance Requirements

Diaphragm pumps typically offer relatively low maintenance due to their seal-less design, with periodic diaphragm and valve inspection recommended.

• What types of fluids are suitable for this pump?

  This type of pump is ideal for water-like fluids, including solutions containing proteins, polymers, cell suspensions, colloidal solutions, and dairy products, particularly where shear-sensitive materials are involved.

• Is this pump suitable for sterile applications?

• What are the advantages of a 4-piston diaphragm pump?

• Can this pump handle abrasive media?

• What level of pulsation can be expected?

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.
