More About this Item

The Masterflex® L/S® High-Pressure pump system enables peristaltic fluid transfer using flexible tubing - at higher pressures. This innovative tubing pump system transfers fluids at pressure up to 125 psi (8.5 bar). Maintenance is quick and easy - simply change the tubing. Unlike ordinary high-pressure pumps, there are no gears, valves, seals or diaphragms to disassemble for cleaning, which saves you time, money, and downtime. This pump is ideal for chemical injection or sterile filtration because the fluid remains in the tubing at all times, with absolutely no contact with the pump's moving parts. The system uses Masterflex® High-Pressure PharMed® BPT pump tubing which is FDA compliant and complies with USP Class VI approval criteria.

  • Q:

    Do you have any information about the smoothness of the outflow? Are there noticable pulses, or is the flow smooth?

      A:

      Peristaltic pumps have a pulsed flow. The head on this drive has three rollers, so the pulses are pretty significant. Generally, the more rollers a head has the lower the pulse effect. Also, depending on your applicaiton we may be able to stack heads and connect the tubing with a "Y" and reduce pulsation by 96%. These high pressure heads require too much torque to run alone and use thicker tubing, they cannot be stacked. Another option would be to use a pulse dampener, if compatible and able.
      Please call so we can discuss your application and needs in further detail in order to make a more specific suggestion.

  • Q:

    Please advise if the masterflex pump 77914-00 with this code we have to order and is this pump is complete just to work. May I use the tubing 06409-16 with this pump?

    • STAFF EXPERT

      A:

      This is a complete pump system that comes with everything needed to work.
      Regular size 16 tubing like part number 06409-16 will not work in the head for this pump. Size 16HP will fit in this pump in either PharMed BPT (95664-16) or Norprene (06504-16).
