Quattroflow™, part of PSG®, a Dover company, has released the QF4400HT quaternary (Four-Piston) diaphragm pump which features a high turn-down ratio and accuracy in controlling flow rates. The pump chamber, pump drive, motor and control box in the Quattroflow QF4400HT are all integrated into one unit. The elimination of a separate control box gives the pump a more compact design and a smaller footprint, which could be suitable for applications that require a smaller pump that offers a wide flow range. The design also includes easy “plug and play” installation and startup, and a keypad for manual control and display of the motor speed.
