Product Description:
SP30-1A syringe pump is a programmable precision liquid handling pump module designed for OEM integration and automated fluid control systems. With a rated stroke of 30mm, the pump provides high-precision liquid dispensing and transferring through external computer, PLC, or microcontroller control.
Featuring a compact structure, reliable performance, and multiple communication interfaces, SP30-1A is suitable for applications requiring accurate and repeatable liquid handling, including laboratory automation, analytical instruments, microfluidics, chemical synthesis, biotechnology equipment, and OEM fluid control systems.
The pump adopts a stepper motor-driven ball screw structure with a built-in photoelectric encoder for real-time out-of-step detection, ensuring stable operation and precise positioning. Programmable acceleration, deceleration, start speed, maximum speed, and stop speed allow flexible adjustment according to different application requirements.
Key Features:
- Programmable Precision Liquid Handling
Controlled by external computers, PLCs, or microcontrollers to achieve accurate liquid dispensing and transferring.
- High Accuracy and Repeatability
Liquid volume accuracy is less than 1.0%, and repeatability error is less than 0.2% under full stroke conditions with deionized water.
- Reliable Closed-Loop Control
Equipped with a photoelectric encoder to detect motor out-of-step conditions and ensure accurate plunger movement.
- Flexible Communication Options
Supports RS232, RS485, and CAN communication protocols for easy integration with automated systems.
- Multiple Pump Synchronization
Up to 15 units of SP30-1A syringe pumps can be connected together for multi-channel fluid control applications.
- Wide Syringe Compatibility
Compatible with various precision glass syringes from 50μL to 12.5mL, meeting different flow rate requirements.
- Valve Control Capability
Supports multiple valve types, including 3-port, 4-port, distribution valves, and multi-port valves.
- Compact OEM Design
Small footprint and modular structure make it easy to integrate into laboratory instruments and automated equipment.
