503Z/ZL：Standard DC geared motor

503Z/BT：57 stepper motor 

The 503Z Inline Peristaltic Pump is a compact, high-precision fluid handling solution designed for stable dosing, hygienic transfer, and industrial-grade reliability. With a maximum flow rate of ≤2185 mL/min, it is widely used in medical, laboratory, food, and industrial automation systems.

Key Features

1. Quick Tube Loading Slider Compression Structure

The slider-type compression mechanism allows fast and easy tube installation and replacement, improving maintenance efficiency.

2. Adjustable Tube Gap Design

Supports adjustable roller gap, enabling compatibility with high-viscosity fluids while preventing leakage and overpressure. It also allows fine adjustment of discharge pressure.

3. Flexible Tubing Installation Options

Supports straight tubing installation, U-shape installation, and combined U + straight tubing layouts, offering flexible system integration for different applications.

4. Compact Direct-Drive Structure

The pump head is directly connected to the motor shaft, resulting in a compact structure, stable operation, and space-saving design.

5. Multiple Connector Options

Compatible with various fittings including straight, elbow, reducer, and extended connectors for different piping systems.

6. High Flow Capacity

Supports tubing types 24#, 35#, and 36#, with a maximum flow rate of up to 2185 mL/min.

7. Precision 3-Roller Design

Equipped with a 3-roller structure, CNC-machined rollers ensure smooth fluid delivery, reduced pulsation, and high dosing accuracy.

8. Hygienic Fluid Transfer

Liquid only contacts the tubing, ensuring contamination-free operation suitable for food-grade, medical, and laboratory use.

9. Forward & Reverse Operation

Supports bidirectional flow by changing motor direction for flexible system control.

10. Easy Maintenance Design

No valves or seals required. Only tubing is consumable, making maintenance fast and cost-effective.
