Product Introduction

Focusing on micro-liter-level continuous fluid transfer, this system utilizes a dual-actuator precision-coordinated design. Combined with a proprietary compensation and calibration algorithm, it delivers a continuously smooth and constant flow rate. While maintaining the high-precision advantages of micro-syringe pumps, its core feature focuses on low-pulsation, highly stable constant flow, making it perfectly suited for a wide range of low-flow precision fluid delivery applications.

  • Microliter-Scale Precision Fluid Control: Enables continuous, uninterrupted liquid transmission.
  • Multiple Operation Modes: Supports Continuous Transfer, Volumetric Metering, and Timed Metering to adapt to diverse application scenarios.
  • Equipped with RS232, RS485, and switching value interfaces, supporting host computer (PC) control.
  • Proprietary Metering Algorithm with Onboard Storage: Real-time logging of switching valve and syringe cycle counts simplifies maintenance and operations.
  • Independently Controllable Actuators: Supports autonomous networking for easy equipment integration and system matching.
  • Intelligent Calibration & Dynamic Compensation Algorithms: Combined with a linear correction model to ensure long-term, high-precision operation.
  • Full Closed-Loop Feedback Control: Integrated with hardware overload protection and software alerts to effectively safeguard equipment and consumables.
  • Ultra-Quiet Mechanical Structure: Paired with custom stepper motors and optimized via vibration simulation to ensure exceptionally quiet operation with low resonance.
  • Made of stainless steel with a powder-coated finish for excellent corrosion and aging resistance, suitable for both laboratory and industrial environments.
