Eliminates Flow Rate Pauses & Drop-Offs The DUAL-NE-1000X Continuous Pump System eliminates the problem of flow rate drop-offs and pauses found in Push-Pull syringe pump systems. With Push-Pull systems, one syringe infuses, while the other refills, then they switch directions. This switch of directions causes a delay in flow while the syringes are primed. The DUAL-NE1000X Continuous Pump System solves the inconsistent flow rate problems of push-pull pumps. How it works: The refilling syringe pump fills the syringe at a faster rate than the infusing syringe pump infuses, giving it time to prime the syringe after the syringe is filled, or even overlap the infusion to create a seamless transition between syringes. The smoothness of the transition between syringes can be fine tuned by adjusting the infusion rate, refill rate, priming rate, prime volume and overlap volume parameters. Description: Two single syringe pumps, each pump holds 1 syringe up to 60 cc, or 140 cc partially filled. Infusion rates from 0.73 µL/hr (1 cc syringe) to 2100 mL/hr (60 cc syringe) Includes all the advanced functions and programming features of the NE-1000 family Disposable, Glass, Stainless Steel Syringes and Plumbing Supplies are sold separately. Dual Pump Plumbing Kit, the syringes and plumbing (sold separately, see below), complete the continuous system. Easy-to-use keypad interface
