  • Flow range: 0.12 to 13 LPM (0.03 to 3.5 GPM). Flow rate depends on motor rpm, adapter gear ratio, and tubing size. Pump head range is 20 to 650 rpm.
  • Use one or two I/P pump heads. Pump two different fluids simultaneously at the same or different flow rates.
  • Cast-aluminum adapters feature built-in gear box and are IP56 rated—includes mounting hardware. Adapters maintain integrity of your motor rating up to IP56.

Use these adapters to mount MASTERFLEX I/P pump heads to 56C frame motors or to a metric IEC 72/ISO 63 motor with B5 flange.

  • Q:

    Is there a higher torque model?

    Is there a higher torque model? I'd like to use 6 pump heads like the one shown in the picture. With max output of 1700ml/min per head @ >/= 24 psi.

    Is there a higher torque model?

      Unfortunately, this does not include pump head (even though the pump head is shown in the picture). The pump head must be ordered separately.
