QUATTROFLOW – Single use QF2500SU

Quaternary single use pharmaceutical pumps with flowrate 50 to 2.500 lph


  • Very low pulsation and a constant flow
  • Self-draining design
  • Up to 125:1 turn-down ratio
  • linear flow performance
  • Q-Control available





EPDM, Polypropylene (PP)




Quattroflow QF2500SU Single use pharmaceutical pump with disposable wetted pump chamber.  

The QF2500SU pump is designed to deliver a constant flow with low pulsation for all flowrates. The QF2500SU can pump with a flowrate of 50 liter per hour and pumps 2.500 liters every hour at max capacity. The pump can run dry without risk and the four-piston system ensures low pulsation and self-priming. The Single use pump chamber of the pump is easy and quick to replace.

Single use diaphragm pumps from Quattroflow

Single-Use diaphragm pumps have got a disposable product wetted chamber constructed from solid polypropylene (PP) or injection-molded polyethylene (PE) that can be replaced as a complete unit. The simple disposability of the pump chamber saves time and money by eliminating cleaning validation, sterilization and product cross-contamination. The single use pumps are self-priming and can be run dry. An exchange kit is available to retrofit a multi use pump into a single use pump.

Single-Use pumps are critical to reduce equipment turnaround times in (bio)pharmaceutical processes. In general, multi-product facilities are the typical field of application of the Single-Use pumps (e.g. process development, production of clinical reference samples, contract manufacturing).

Q-Control pump control

Q-Control’s integrated smart pump control has been created to make optimal use of the QF 2500SU. The Q-Control is linked to various flow and pressure sensors to enable automated processes for this pump. Read more here.
