What Quattroflow does
Quattroflow is a specialty brand of quaternary (four-piston) diaphragm pumps serving biopharmaceutical manufacturers globally. The brand operates under PSG (Pump Solutions Group), which is itself a wholly-owned operating company of Dover Corporation (NYSE: DOV), and is headquartered in Kamp-lintfort, Germany, with PSG Germany GmbH based in nearby Duisburg. Quattroflow's product line consists of multiple-use pumps in six sizes (150, 1200, 4400, 5050, 10k, and 20k) for fixed stainless-steel production setups and single-use pumps in four sizes for disposable manufacturing workflows, covering flow rates from 1 liter per hour to 16,000 liters per hour. Supporting accessories include control boxes, power boxes, diaphragm sensors, and PID pressure controllers.
The underlying technology addresses bioprocess fluid handling requirements that are unsuitable for conventional pumps: low-pulsation and low-shear operation to preserve mammalian, bacterial, yeast, algae, fungal, and insect cells; gentle handling of virus suspensions, viral and bacterial vaccines, and proteins from blood fractionation; and CIP/SIP capability for regulated production environments. Single-use pump chambers can be replaced in under one minute, enabling rapid batch changeover in single-use manufacturing lines. Quattroflow does not embed software, AI, or digital control layers into its core pumps; instrumentation is limited to analog/digital PID pressure control and diaphragm sensors.
The company sells capital equipment and recurring single-use chambers through PSG's global authorized distributor network rather than via direct enterprise sales, with quote-based pricing and no public price list. End customers are enterprise biopharma OEMs and contract manufacturers using Quattroflow pumps in chromatography, virus filtration, tangential flow filtration, and inline blending unit operations. PSG/Dover do not disclose Quattroflow revenue separately, and the brand has 51-100 employees. PSG has continued to expand the parent portfolio in 2025 with the acquisitions of Cryogenic Machinery Corp. and ipp Pump Products GmbH, although those moves sit at the PSG corporate level rather than within the Quattroflow brand itself.
