The P3000+ High-Pressure Constant-Flow Pump integrates multiple advanced designs and functionalities to ensure stable, precise, and safe operation under high flow rates and high pressure conditions. Its core features include: an efficient three-plunger parallel reciprocating pump structure that significantly reduces infusion pulsation and ensures flow rate stability; a high-power AC servo motor for smooth and accurate operation, effectively enhancing the reproducibility of preparation results at high flow rates and the stability of the gradient system; dual correction capabilities for mobile phase compression coefficient and flow rate accuracy, enabling intelligent flow compensation within ±15% to ensure extremely high flow rate precision; support for external full reverse control via RS485 interface from a chromatography workstation, facilitating the easy construction of high-precision binary high-pressure gradient systems and flow rate gradient programming to meet complex sample preparation requirements; equipped with real-time pressure monitoring, high/low pressure limit alarms, and a dual protection mechanism with mechanical safety valves, which automatically trigger protection when system pressure exceeds set values or internal temperature becomes excessively high (e.g., 85°C), fully ensuring the safety of both the instrument and operators.
