Quattroflow™ Quaternary Diaphragm Pumps Protect Sensitive Biological Media Better Than Competing Alternatives
Quattroflow™ develops and manufactures, in close cooperation with our customers, quaternary (four-piston) diaphragm pumps specifically designed for critical applications in the biopharma as well as food and beverage industries. The Quattroflow™ pump’s method of operation allows it to gently, safely and securely convey aqueous solutions and biological products that are shear sensitive. The four-piston design does not include a mechanical shaft seal or wetted rotating parts, ensuring total product containment without abrasion. Additionally, the four-piston pumping principle enables risk-free dry running, low pulsation, self-priming, and minimal particle generation. Quattroflow™ pumps are available with cleanable multiple-use stainless steel or disposable single-use plastic pump chambers.
Disposable pump chamber offers tool-free installation. Retrofittable on QF150 drives. 500:1 turn-down ratio, linear flow performance with a flow range of 0.02 – 8 gph (0.06 – 30 lph)
Fully disposable machined polypropylene pump chamber is easy to replace and is cost-effective. Integrated controller is standard. Flow range: 0.26 gph to 48 gph (1 l/h to 180 l/h)
Fully disposable machined polypropylene pump chamber is easy to replace and is cost-effective. Quaternary diaphragm pump technology enables gentle product treatment with no particle generation. Flow range: Eccentric Shaft 3° — 2.64 gph to 211 gph (10 l/h to 800 l/h); Eccentric Shaft 5° — 5.3 gph to 317 gph (20 l/h to 1,200 l/h)
Fully disposable machined polypropylene pump chamber is easy to replace and is cost-effective. Quaternary diaphragm pump technology enables gentle product treatment with no particle generation. Flow range (Eccentric Shaft 6°): 40 gph to 1,321 gph (150 l/h)
QF5K & QF5kSU
Designed to achieve a flow rate between 50 and up to 6,000 lph, the next generation Quattroflow QF5k introduces improvements to critical functionality that the biopharma market demands.
