More About this Item

Preparative digital pump provides high flow rates and high pressure capabilities with consistent performance. Dual ball and seat check valves in each head reduce pulsation.

Microprocessor controls motor drive circuits, interfaces with the chemical-resistant keypad and digital LED display, receives signals to refill based on flow rate, and provides RS-232 communication. Pressure control feature provides real-time pressure monitoring with upper and lower pressure limits. Other features include prime/purge valves for easy solvent change and priming capabilities, auto-flush piston wash, run/stop inputs, and dual-voltage capabilities.
