QuattroTec Diaphragm

QuattroTec Quaternary Diaphragm Pumps for Other Hygienic Applications

State-of-the-art Quattroflow™ Quaternary Diaphragm Pumps are a safe, reliable and efficient pump choice for a wide variety of applications in the biopharma industry. QuattroTec Series pumps have been developed through the adoption and redesign of the Quattroflow pumps to retain the advantages and concurrently achieving the requirements for other hygienic applications, including in the food and beverage industry.

The QuattroTec Series consists of three sizes — QT10, QT20 and QT30 — with maximum capacities of 180 lph (0.8 gpm), 1,200 lph (5.3 gpm) and 5,000 lph (22 gpm) at 1 mPas. The basic version of a QuattroTec pump features a wetted pump chamber made of 316L stainless steel, while the valves are made of EPDM and the diaphragms of Santoprene™. Special equipment and accessories are available that include alternative drives, control box, plastic pump chamber and diaphragm sensor.

Quattroflow QuattroTec Quaternary Diaphragm Pumps are electrically driven and truly unique in concept. The pump's operation mimics that of the human heart, which is the perfect technology for the safe, reliable and efficient transfer of liquids. The four-piston diaphragm/valves combination enables gentle pumping like soft heartbeats. Each stroke is derived by an eccentric shaft connected to an electric motor. This method of operation results in a pump that offers low-friction, low-shear and low pulsation, which make the QuattroTec pump the ideal solution for critical applications involving shear sensitive and expensive ingredients that require precise flow, high turndown and accurate dosing in a hermetically sealed environment, coupled with the ability of transferring clean-in-place (CIP) media with the same pump.
