  • Q:

    Can you clarify the power requirement for this pump? We are having it run on a solar panel/battery system with an inverter and I want to make sure the loading is only 75W. The 2.2A at 115VAC rating is what has me worried, but that is misleading because current and voltage are not in phase correct(i.e. P does not equal 2.2A times 115V)?

      Supply voltage limits: all models 90 to 260 Vrms @ 50/60 Hz
      (Universal Input) Single Phase Only
      Current, max.: all models 1.8A @ 115 Vrms, or 1.1A @ 230 Vrms

  • Q:

    Will this pump work with the hand-held remote controller, part number 07528-80, which is available for the Variable-Speed Console Drive, HV-07258-10?
    Asked on 4/19/2016 by CuriousCat from Bellevue, WA

    1 answer



      This pump will not work with that specific hand-held remote because the PIN connections would be different. You could however utilize the hand-held remote part number 07523-97 with this drive.

  • Q:

    we are using this pump remote, controlling it through the DB9 connector. Is there a way to count the motor rotations?
    Is something known about mounting a hall sensor to the head? Can you please advise what the best way is to go?
    Thank you in advance,
    Best regards,

      Unfortunately, this unit does not allow for a way to count motor rotations remotely. The RPM is only available to be displayed in continuous mode on the screen. This unit has a DB25 connector mounted on the back for remote outputs. Pin 1 represents voltage input and pin 14 represents voltage output.

  • Q:

    Hi, how often should I do the calibration?
    Asked on 10/25/2015 by Ying from Princeton, NJ

    1 answer



      It would depend on how often you use the pump. You should calibrate anytime the application changes to receive optimum accuracy. You should calibrate when the tubing is changed as well. If you see an issue with the accuracy, the pump should be calibrated.

  • Q:

    Can the break - in be done with water or do we have to use actual product?

      You can use water or just run the tubing dry.

  • Q:


    I used to own the older model of the L/S pump WU-07523-50. My application requires the pump connecting to a timed power outlet. With the old model, when the power is cut and resumed the drive automatically turns back on with the preset speed.

    However, recently when I replace it with this newer model WU-07522-30, the drive will not resume running after the power is cut off and resumed.

    Is there a setting or workaround where I can control the pump with a timed outlet like the older model?

    Asked on 1/15/2015 by Brian from United States

    1 answer



      Power cycling this drive with a timer is not recommended. I would suggest using the internal batch dispensing options to set the delay between cycles.

Comments about Masterflex L/S Digital Drive, 600 RPM, 115/230 VAC 0:

We are overall satisfied with this product. Although a bit expensive for what it is, in the long run it is worth it and is good value. It is so much easier to use this device then to manually pipet large amounts of tubes. The interface is simple and easy to use. The only down side is that the calibration process takes a bit too long, and we often have to estimate then measure ourselves. But for aliquoting the same volume it seems to be very accurate.
