Four-piston diaphragm pumps

Quattroflow® is a leading manufacturer of four-piston diaphragm pumps, designed especially for demanding applications in biotechnology and the pharmaceutical industry. Quattroflow pumps provide gentle and pulsation-free product handling, which is essential for sensitive and valuable products. The unique four-piston design enables extremely smooth flow, low shear force, as well as risk-free dry running and self-priming. The Quattroflow range includes both versatile stainless steel pumps and single-use models, where the fluid head can be quickly replaced without the risk of cross-contamination.

Applications

• Processes in biotechnology and the pharmaceutical industry (e.g., cell cultures, virus and bacteria handling, chromatography, filtrations)
• CIP/SIP-cleanable and high hygiene requirement applications
• Also suitable for laboratory use and small production batches

Advantages

• Gentle and pulsation-free flow: The four-piston design enables extremely smooth flow and minimizes product shearing and foaming.
• Self-priming and dry running capability: The pumps withstand dry running and are self-priming, which increases reliability and safety.
• Versatility: Wide flow range (1 ml/min – 16,000 l/h), suitable for both small and large production volumes.
• Energy efficiency and low lifecycle costs: No mechanical seals or rotating parts, which reduces maintenance needs.
• Easy to clean: CIP/SIP compatibility in reusable models, in single-use models the fluid head can be replaced without cleaning.
• Tightness and safety: Seal-less design prevents leaks and enables safe product handling.
• Compact and quiet design: Easy to install and integrate into existing systems.
