Quattroflow – QF5k Quaternary Diaphragm Pumps

Quattroflow extends its next generation Quaternary (Four-Piston) Diaphragm Pumps with the new QF5k multiple-use offering, adding to the range for drainable and ventable technology.

Designed to achieve a flow rate between 50 and up to 6,000 lph, the next generation Quattroflow QF5k introduces improvements to critical functionality that the biopharma market demands.

Quattroflow multiple-use pumps now cover a flow capacity between 1 to 16,000 lph with multi-use pump sizes now available to meet the needs from small R&D projects to full-scale manufacturing environments.

Next generation QF5k pumps offer the following features and benefits:

  • Increased max. flow rate of 6,000 lph with most drives
  • Clean-In-Place/Steaming-In-Place (CIP/SIP) and autoclavability
  • Self-draining design to minimize non-recoverable product
  • Enhanced venting to reduce the minimum flow rate required to remove entrapped air during priming
  • Patented valve plate design to achieve sel-draining and venting
  • Up to 120:1 turndown ratio
  • Improved linear flow performance
  • High flow stability across entire flow range
  • AC version: With 3 phase asynchronous motor
  • Compact drive: Minimal footprint due to “pump next to motor” design o HT drive: Plug-and-play version with integrated motor controller and keypad
  • Q-Control: Integrated pump controller with direct sensor connection
  • Diaphragm monitoring available as option
  • Motor flange design to reduce pump noise and simplify coupling alignment
  • Typical applications include: Chromatography, TFF, virus filtration, sterile filtration, depth filtration
