Masterflex L/S Computer-Compatible Digital Drive; 600 rpm

EW-07551-00

  • Interface this digital drive to a PC for automated lab and process applications--or use as a stand-alone dispensing pump
  • Precision digital drive offers a maintenance-free high-accuracy motor and an all-new graphical interface that makes setup and operation easier than ever
  • Flow rate 0.001 to 3400 mL/min with L/S tubing. Flow rate depends on drive rpm and tubing size.
  • Graphical LCD shows four operating modes continuous run, timed dispense, copy dispense, volume dispense. View pump performance continually.
  • Menu-driven interface lets you select one of seven languages for programming and operation
  • Dispense by mL—volume in mL of each dispense, 0.001 to 9999 mL; Copy—1 to 9,999 dispense cycles; or SEC—time interval between each dispense cycle (1 sec to 99 hr, 59 min, 59 sec)
  • Brushless, maintenance-free motor offers ±0.1% speed control accuracy with a 6000 to 1 turndown ratio
  • Interface with a PC via RS-232 or USB connection
  • Remote control via DB25 female connector on drive:
    --Speed control input 0 to 20 mA, 4 to 20 mA, or 0 to 10 V;
    --Pumping direction requires open collector or contact closure;
    --Start/stop/purge requires open collector or contact closure;
    --Tachometer output 0 to 20 mA, 4 to 20 mA, or 0 to 10 V, open collector
These precision drives offer analog remote control options and simple programming—ideal for automated process applications. Drives feature a programmable dispense interval that lets you set the delay between dispense cycles for convenient, automated dispensing. Programmed calibration ensures dispense and display accuracy—drive stores one calibration value per tubing size.
Program the drive via the simple membrane keypad; keypad lock/unlock feature protects settings. Motor is reversible so you can purge tubing before or after pumping and pump fluid in either direction.

  • Q:

    Can this pump be controlled by a third party automated robotic software? I want to integrate this into my Hamilton Robotic system starPlus

      A:

      This unit can be controlled using RS-232 protocols via a computer or other digial interface (a list of the commands is avialable in the manual). You can also control the drive using analog signals (4-20, 0-10 V). We also offer WINLIN software to control the pump remotely (part number 07551-70).

  • Q:

    Can you tell me if I can program a stop ramp, so that the flow rate reduces as the liquid reaches the top of the fill vessel.
    Asked on 9/9/2009 by Paul from Andover, Hants.

    1 answer

    • STAFF EXPERT

      A:

      There is not a ramp program or option, but if were to use the optional software you would be able to create steps. For example you could program it to run at slower and slower speeds for certain volumes or amounts of time. The software is part number 07551-70.

  • Q:

    Hi, Im looking for a pump which has a remote speed control feature by either a signal in the range of 0-10 volts or 4-20milliamp, im not entirely sure what to look for on the item descriptions.

    • STAFF EXPERT

      A:

      You need to look for "speed control input" or "remote capabilities" in the item description. Our most basic L/S model that can handle the 2-10VDC or 4-20mA is model number 77521-40.
