Special Application: Continuous Infusion (Push-Pull) and Dual Syringe Pump

Using 2 NE-4000 pumps attached with a cable, one pump will infuse while the other pump refills or have simultaneous infusion.

  • Fully programmable; automation capable
  • Operates stand-alone or from a computer
  • Infusion and withdrawal
  • Available in Microfluidics (NE-4002X) and OEM (NE-4500) versions
  • Set a single pumping rate and/or dispensing volume
  • Program up to 41 pumping phases that change pumping rates, set dispensing volumes, insert pauses, control and respond to external signals, sound the buzzer
  • Network, control, and monitor up to 100 pumps with one computer
  • Worldwide power supplies available
  • Motor stall detection
  • Dispensing accuracy of +/-1%
  • Unlimited lifetime technical support
  • Two year warranty

High pressure notes:

The NE-4000 produces about 15 lbs(7.5 lbs/syringe) of linear force at top speed and about 100 lbs(50 lbs/syringe) at slow speeds. 10 ml/hr is an example of slow speed. The pressure that can be generated is relative to the syringe size. On a 60 ml syringe, this would roughly produce about 30 psi.
