How to Select your Masterflex Pump System

Define Your Application Requirements.

  • What flow rate do I need?
  • What chemical am I pumping?
  • Do conditions like fluid viscosity or back pressure play an important role in my application?

    Select a Pump Series Based on Your Flow Rate.

  • C/L®
  • 0.002 to 37 mL/min
  • L/S®
  • 0.0006 to 3400 mL/min
  • I/P®
  • 0.012 to 13 LPM
  • B/T®
  • 0.3 to 45 LPM

    Select the components to fit your application.

  • I/P and L/S pumps systems are divided into three categories—pump head, tubing, and drive.
  • C/L and B/T pumps systems are divided into two categories—pump head and drive.
  • To complete your tubing pump system, choose a pump head, tubing, and drive from within the same series.

  • What To Consider When Choosing a Pump Head

  • Flow rate—
    Different pump heads have different flow rate capabilities.
  • Frequency of tubing changes—
    Some pump heads enable very rapid tubing changes.
  • Desired number of channels—
    Pump heads are stackable in most cases.
  • Chemical compatibility—
    If chemicals spill, the pump head materials become important.
  • Accuracy—
    Standard pump heads deliver the most accurate and repeatable flow rates.

    What To Consider When Choosing Tubing

  • Flow rate—
    Tubing size directly affects flow rate; choose the size based on your flow needs.
  • Chemical compatibility—
    The compatibility of tubing with a variety of commonly used chemicals.
  • Tubing life—
    Tubing Life Technical Data contains information about life expectancy for all tubing formulations.
  • Fluid viscosity, presence of solids, back pressure, or suction lift—
    High performance tubings are best for these conditions.
  • Fluid temperature—
    Information concerning the temperature range for each tubing formulation can be found on a tubing’s Tubing Formulations.

    What To Consider When Choosing a Drive

  • Flow rate—
    The rpm of the drive directly correlates to flow rate.
  • Fixed- or variable-speed—
    Variable-speed drives enable flow rate adjustment.
  • Accuracy of flow rate or dispense volume—
    Many drives have digital speed control circuitry for highly accurate and repeatable flow rates.
  • Remote control or computer interface—
    Some drives can connect to your process controller or can be operated by a footswitch.
  • Environmental protection against hazards— Many drives are sealed against dust and water exposure.
