Quattroflow Pumps

Quattroflow™ develops and manufactures 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.

Single Use or Multi-Use?

Quattroflow pumps are available in a wide variety of sizes and pump head options. From the smallest QF30, right up to the QF5050, there is a model to meet your pumping requirements, and depending on your process design, most models are available with either a single-use pump head, or multi-use pump head configuration. 

The smaller QF30 and QF150 models, come with a standard integrated controller. For all other sizes, a separate control box is available. In addition, the sizes QF1200 and QF4400 are also available in a space saving compact version with an integrated controller and high turndown ratio.

In addition, the Quattroflow single-use QF150 and QF1200 pumps can be equipped with the EZ-Set Pump Chamber Replacing System. The EZ-Set's comfortable handgrip design makes replacing a Quattroflow single-use pump chamber very easy and fast – within 30 seconds or less by hand. It is quick, easy, and safe. Proper tightening will be achieved just by visual guide and no torque wrenches are needed.
