1. Introduction
This manual provides essential instructions for the safe and efficient operation, installation, and maintenance of your QKVJULBN BP300-S42UN32A Peristaltic Pump. Please read this manual thoroughly before using the pump to ensure proper function and to prevent damage or injury. Keep this manual for future reference.
The QKVJULBN BP300-S42UN32A is a high-precision peristaltic pump designed for accurate dosing and transfer of various liquids, gels, and greases. Its compact size makes it suitable for applications requiring small, controlled flow rates.
2. Safety Information
Always observe the following safety precautions to prevent personal injury or damage to the pump:
- Ensure the power supply voltage matches the pump's requirements (12V or 24V, as specified for your model).
- Do not operate the pump with damaged tubing or electrical connections.
- Avoid contact with moving parts during operation.
- Do not immerse the pump in liquid.
- Use only compatible tubing materials for the liquids being transferred.
- Disconnect power before performing any maintenance or tubing changes.
- Keep the pump away from excessive heat, moisture, and corrosive environments.
3. Product Overview
The BP300-S42UN32A peristaltic pump consists of a stepper motor, a pump head with rollers, and a transparent cover. The liquid is contained entirely within the tubing, preventing contamination and simplifying cleaning.
4. Setup
4.1 Unpacking
Carefully remove the pump from its packaging. Inspect for any visible damage. Retain packaging for future transport or storage.
4.2 Mounting
The pump features an integrated mounting bracket. Secure the pump to a stable surface using appropriate fasteners (not included) through the holes in the bracket. Ensure the pump is level and stable to prevent vibration during operation.
4.3 Tubing Installation
- Open the transparent cover of the pump head. This may involve unlatching or unscrewing retaining clips.
- Carefully insert the appropriate peristaltic tubing into the pump head, ensuring it sits correctly within the rotor path.
- Close the transparent cover, ensuring it is securely latched or screwed down. The tubing should be compressed by the rollers.
- Connect the inlet tubing to your liquid source and the outlet tubing to your destination. Ensure all connections are secure to prevent leaks.
4.4 Power Connection
Connect the pump to a compatible 12V or 24V DC power supply (not included) according to the wiring diagram provided with your specific motor controller. Ensure correct polarity to avoid damage.
5. Operating Instructions
5.1 Initial Start-up
- Ensure all tubing connections are secure and the pump head cover is properly closed.
- Verify that the liquid source is available and the destination is ready to receive the liquid.
- Apply power to the pump. The stepper motor will begin to rotate the rollers.
5.2 Flow Control
The flow rate of this peristaltic pump is controlled by the speed of the stepper motor. Adjust the motor speed using your external stepper motor driver/controller (not included) to achieve the desired flow rate. Refer to your motor controller's manual for specific speed adjustment procedures.
5.3 Shutting Down
To stop the pump, remove power from the stepper motor. For extended periods of non-use, disconnect the pump from the power supply and drain any remaining liquid from the tubing.
6. Maintenance
6.1 Tubing Replacement
Peristaltic tubing is a wear item and should be replaced periodically, depending on usage and the type of liquid being pumped. Signs of wear include cracking, hardening, or reduced flow accuracy.
- Disconnect power from the pump.
- Open the pump head cover.
- Remove the old tubing.
- Clean the pump head and rollers if necessary (see 6.2).
- Install new, compatible tubing as described in Section 4.3.
- Close the pump head cover securely.
6.2 Cleaning the Pump Head
Regularly inspect the pump head and rollers for any residue or debris. If cleaning is required:
- Disconnect power and remove the tubing.
- Wipe the rollers and the interior of the pump head with a damp cloth. For stubborn residues, use a mild, non-abrasive cleaning solution compatible with the pump head materials.
- Ensure all parts are completely dry before reinstalling tubing and operating the pump.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power or incorrect wiring Motor controller issue | Check power connections and polarity Verify motor controller functionality |
| No liquid flow | Tubing kinked or blocked Pump head cover not closed properly Worn tubing Air in tubing | Inspect and clear tubing Ensure pump head cover is secure Replace tubing Prime the pump by running it until liquid flows |
| Inconsistent flow | Worn tubing Air bubbles in liquid Inconsistent motor speed | Replace tubing Ensure liquid source is free of air Check motor controller for stable output |
| Excessive noise | Loose mounting Worn rollers or bearings Debris in pump head | Tighten mounting fasteners Contact support for replacement parts Clean pump head and rollers |
