Quattroflow 4-Piston Diaphragm Pumps

Quattroflow’s positive displacement pumps incorporate a four piston-diaphragm technology with no mechanical seals that is driven by an eccentric shaft and electrical motor.  Quattroflow products primarily serve the pharmaceutical and biotech industries that require reliability, product safety, purity and cleanability. Whether in cross-flow systems, chromatography devices or centrifuges, the pumps gently convey aqueous solutions and biological products sensitive to shear force ranging from blood to vaccines without denaturing them.

The Quattroflow production programme consists of four pump series:

QF 150: This pump series is the best entry for laboratories, research centers and universities - small, portable, quite and scalable.

QF 1200: A versatile tool for a lot of applications in laboratories, pilot and production plants worldwide. Stainless steel valve plate and new diaphragms allow inline steaming, autoclaving and easy cleaning.

QF 4400: The QF-4400 Series is used e.g.in mid-sized crossflow systems and in chromatography systems, where gradient mixing requires a 100:1 turndown ratio.

QF 20K: The biggest Quattroflow pump with a max. capacity of 20000 l/h meets the requirements of high process volumes.

The pump series 150, 1200 and 4400 are also available in a “single use” version with product chambers made of polypropylen. Main focus is the demand of the users for prevention of expensive and time-consuming flushing.
