Duisburg, Germany – November 30, 2020 – Quattroflow?, part of PSG^?, a Dover company and a leading brand of positive displacement quaternary diaphragm pumps, has extended its line of HT drives with the addition of the new QF2500HT Quaternary (Four-Piston) Diaphragm Pump. With a compact design, high turndown ratio, and a maximum flow rate of 2,500 lph (660 gph), the new QF2500HT pump is ideally suited to meet the needs within demanding biopharma applications, including chromatography, TFF, virus filtration, sterile filtration, and depth filtration.

The Quattroflow QF2500HT incorporates all the same industry-leading features and benefits as the QF2500 model with space-saving “All-in-One” technology that integrates the pump chamber, pump drive, motor and control box into one unit. The elimination of a separate control box results in easier handling while giving the QF2500HT a more compact design and smaller footprint, which is ideal for applications that require a smaller pump that offers an extended turndown ratio for a wider range of flow rates. The design of the QF2500HT includes easy plug and play installation and startup, and a keypad for manual control and display of the motor speed.

QF2500HT pumps excel in biopharma applications thanks to industry-leading designs, including pump chambers that provide improved drainability to maximize product recovery. The QF2500HT pump also features higher flow stability even at low flow rates, linear flow performance, high accuracy in controlling flow rates, and clean-in-place (CIP)/steam-in-place (SIP) capability. The QF2500 model can be integrated with the new Q-Control Integrated Pump Controller to provide users with automated control over their pump operations.
