Introducing Quattroflow™’s Q-Control Integrated Controller: The Latest Innovation in Maximising Pump Automation

17 December 2021 Q-Control Integrated Controller

Quattroflow™ develops and manufactures, in close cooperation with our customers, quaternary (four-piston) diaphragm pumps specifically designed for critical applications in the biopharma, and food and beverage industries.

How Quattroflow™ Works?

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.

Truly unique in that their method of operation, Quattroflow Quaternary Diaphragm Pumps mimic the human heart, which is the perfect model for the safe, reliable and efficient transfer of biological materials. With an operation that offers low friction, low shear and low pulsation, Quattroflow pumps are ideal for critical applications within biopharma manufacturing. These include Tangential Flow Filtration (TFF), Chromatography (RFC), centrifuge feed, sterile virus filtration, purification and inline dilution. Quattroflow pumps can also be outfitted with a single-use liquid chamber, which enables them to meet strict speed-to-market manufacturing demands.

Quattroflow™’s Latest Innovation: Q-Control Integrated Pump Controller

Quattroflow™, part of PSG®, a Dover company and a leading brand of positive displacement quaternary diaphragm pumps, is pleased to announce the availability of its new Q-Control Integrated Pump Controller, which is designed to interface with a variety of flow and pressure sensors to provide users with automated control over their pump operations.

Available for Quattroflow multiple- and single-use quaternary diaphragm pump models QF30, QF150, QF1200, QF2500 and QF4400, the Q-Control eliminates the need for an external PLC thanks to a variety of built-in smart control functions, including an autotune function that automatically finds optimal PID parameters and a dispensing function that allows the pump to automatically fill defined volumes of liquid. The system also allows users to configure alarms to stop the pump and features an RS485 Modbus communication port, trend data, alarm logging and remote operation.

Quattroflow pumps primarily serve biopharma applications that require gentle displacement, reliability, product safety, purity and accuracy. The pumping principle enables risk-free dry running, low pulsation, self-priming, and minimal particle generation. With single- and multiple-use models available, Quattroflow has a pump to fit every application need.
