Hyuduo G528 DC12V Mini Peristaltic Pump User Manual

1. Introduction

The Hyuduo G528 DC12V Mini Peristaltic Pump is designed for precise fluid transfer in laboratory and bioengineering applications. Its compact size and adjustable flow rate make it suitable for various research settings requiring accurate liquid handling. This manual provides essential information for the safe and efficient operation of your peristaltic pump.

Key Features:

• Precision Fluid Control: Adjustable flow rate from 0-150ml/min and speed range of 0.1-60rpm for accurate liquid transfer.
• Versatile Direction Control: Media direction can be changed by reversing the power supply polarity, offering flexibility in tubing setup.
• Compact Design: With a 32mm motor diameter and 23mm height, it fits into confined spaces while maintaining durability up to 40°C (104°F).
• Multiple Tube Options: Compatible with 1x3mm, 2x4mm, and 3x5mm rubber tubes to accommodate different fluid viscosities.
• Low Power Operation: Operates on a 12V DC power supply with a current of 250-300mA, ensuring energy efficiency during prolonged use.

2. Safety Information

Please read and understand all safety instructions before operating the pump. Failure to follow these instructions may result in injury or damage to the product.

• Ensure the power supply matches the specified voltage (DC 12V).
• Do not operate the pump in environments outside the specified temperature range (0-40°C).
• Avoid contact with moving parts during operation.
• Always disconnect power before performing any maintenance or changing tubing.
• Use only compatible tubing sizes (1x3mm, 2x4mm, 3x5mm) to prevent leaks or damage.
• Keep the pump away from moisture and corrosive substances.

5. Setup

5.1 Mounting

The pump features multiple mounting holes for secure installation. Use appropriate screws (not included) to fix the pump to a stable surface. The installation hole center distance is approximately 48.5mm (1.9in).

5.2 Tubing Installation

1. Select the appropriate rubber tube (1x3mm, 2x4mm, or 3x5mm) based on your fluid viscosity and desired flow rate.
2. Carefully insert the ends of the tubing into the inlet and outlet connectors on the pump head. Ensure a snug fit to prevent leaks.
3. Verify that the tubing is not kinked or obstructed.

5.3 Electrical Connection

Connect the pump to a DC 12V power supply. The direction of fluid flow through the peristaltic pump is determined by the polarity of the power supply wiring. Connect the positive (+) and negative (-) terminals accordingly to achieve the desired flow direction.

6. Operating Instructions

6.1 Powering On/Off

Once the electrical connections are secure, apply DC 12V power to the pump to start operation. Disconnect power to stop the pump.

6.2 Adjusting Flow Rate

The flow rate of the pump is directly proportional to the motor's rotational speed. If your power supply allows for variable voltage output, adjusting the voltage within the 12V DC limit can control the pump's speed and thus the flow rate (0.1-60rpm, corresponding to 0-150ml/min depending on tube size).

6.3 Changing Flow Direction

To reverse the direction of fluid flow, simply reverse the polarity of the DC 12V power supply connection to the pump. Ensure power is disconnected before changing wiring.

7. Maintenance

7.1 Cleaning

Regular cleaning helps maintain optimal performance and extends the pump's lifespan. Disconnect power before cleaning. Wipe the exterior of the pump with a soft, damp cloth. Do not immerse the pump in water or use harsh chemicals.

7.2 Tube Replacement

Over time, the rubber tubing may wear out or become contaminated. Replace tubing as needed to ensure accurate and leak-free operation. Always use new tubing of the correct size and material. Disconnect power, carefully remove old tubing, and install new tubing as described in the Setup section.
