Q-Control Pumps

Quattroflow Q-ControlSmart Control of Your Pump Operations

Q-Control is an integrated pump controller for Quattroflow multiple-use and single-use pumps. It interfaces with a variety of flow and pressure sensors to provide user with automated control over their pump operations. With built-in smart control functions that no longer requires an external PLC, Q-Control leads to a new generation of Quattroflow biopharma pumps.

  • Integrated pump controller that interfaces with different flow and pressure sensors
  • Smart control functions that usually require an external PLC
  • PID control mode for pressure- or flow-controlled pump operations
  • Autotune function to automatically find optimal PID parameters
  • Configurable alarms to stop the pump
  • Dispensing feature to automatically fill defined volumes of liquid
  • RS485 Modbus communication port
  • Trend data and alarm logging
  • Remote operation
  • Available for Quattroflow quaternary diaphragm pump models: QF30, QF150, QF1200, QF2500 and QF4400
