Product Description This is a dual syringe infusion pump capable of low to moderate back pressures.
Two modes of operation, constant flow rate and volume dispense - will operate continuously in RATE mode or accurately dispense a specific amount of fluid in VOLUME mode. Micro-stepping pump profiles deliver very smooth and consistent flow. The pump remembers its last syringe size, flow rate used and configuration settings. In a power failure the Pump can either RESUME or STOP pumping when power is returned.

The diameter of the syringe(s) is entered via the keyboard and the internal microprocessor drives a precision stepper motor to produce accurate fluid flow.
Non-volatile memory stores the last syringe diameter and flow rate along with other configuration data.
The Power Failure Mode can be set to either turn the pump off in the event of power failure or to resume pumping when power resumes.
