New Quattroflow™ QF10k Quaternary Diaphragm Pump on Display at INTERPHEX 2018

by PSG | Mar 02, 2018
QF10k PumpKamp-Lintfort, Germany – March 2, 2018 – Quattroflow, part of PSG®, a Dover company and a leading brand of positive displacement quaternary diaphragm pumps, is pleased to announce that it will be exhibiting its new QF10k quaternary (four-piston) diaphragm pump in Booth 2253 at INTERPHEX 2018. Taking place from April 17-19 in New York, NY, USA, INTERPHEX annually brings together a wide variety of leaders from the pharmaceutical and biotech industries.

Providing a maximum flow rate of 10,000 lph (44 gpm), the new QF10k pump is equipped with an improved, patent-pending stainless-steel pump chamber design that provides excellent drainability to maximize product recovery. In addition, Quattroflow QF10k pumps incorporate a wide variety of other innovative features and benefits, including a maximum pressure of 6 bar (87 psi), 20:1 turn-down ratio, linear flow performance, and high-flow stability even at low flow rates. Quattroflow QF10k pumps also offer Clean-In-Place (CIP)/Steaming-In-Place (SIP) and autoclave capabilities.

Quattroflow will also be showcasing its QF4400HT model pump at the show. The QF4400HT is the ideal solution for a wide variety of biopharmaceutical applications thanks to its high turndown ratio and accuracy in controlling flow rates. Available in both Single- and Multiple-Use variations, the QF400HT incorporates a significant space-saving design: the pump chamber, pump drive, motor and control box are all integrated into one unit. The elimination of a separate control box gives the QF4400HT a more compact design and a smaller footprint, which is ideal for applications that require a smaller pump that offers a wide flow range – from 50–5,000 lph (.22-22 gpm).

In addition, the Quattroflow EZ-Set Pump Chamber Replacing System will be on display. With EZ-Set, users can replace a Single-Use pump chamber in 30 seconds by hand without the use of special tools or torque wrenches. It’s quick, it’s easy, and it’s safe. The comfortable handgrip design of the EZ-Set makes replacing the pump chamber so easy you can do it even while wearing rubber gloves. EZ-Set also reduces downtime between batches.

Quattroflow will share a booth with its sister companies Wilden® and Almatec®.
