5. Setup
5.1 Mounting
Securely mount the pump in a stable location, ensuring adequate ventilation and clearance for tubing connections. Refer to the dimensional drawing in Section 4 for mounting considerations.
5.2 Tubing Connection
- Connect the inlet tubing to the fluid source and the outlet tubing to the destination.
- Ensure all connections are secure to prevent leaks.
- Verify that the tubing is not kinked or obstructed.
5.3 Electrical Wiring
The KPAS-100 uses a stepper motor and requires a compatible stepper motor control board for operation and speed adjustment. Connect the motor wires to your control board according to the pinout diagram. Incorrect wiring can damage the motor or control board.
Figure 3: Stepper motor wiring diagram for the Kamoer KPAS-100. This image illustrates the color-coded wires and their corresponding A+/A-/B+/B- connections for the stepper motor.
Typical Wiring (Refer to your specific stepper driver documentation):
- A+: Black Line
- A-: Red Line
- B+: Blue Line
- B-: Green Line
Note: Wire colors may vary. Always cross-reference with the motor's label or manufacturer's specifications. A customer reported their motor having Green, Red, Orange, Yellow wires, which they successfully mapped to A1: Green, A2: Red, B1: Orange, B2: Yellow. This highlights the importance of verifying the specific wiring for your unit.
6. Operation
6.1 Power On
Once the pump is securely mounted and wired to a compatible stepper motor control board, apply DC 24V power to the control board.
6.2 Speed Adjustment
The flow rate and speed of the peristaltic pump are controlled via the connected stepper motor control board. Refer to your control board's manual for instructions on adjusting motor speed and direction.
6.3 Initial Priming
For initial use or after tube replacement, it may be necessary to prime the pump to ensure consistent flow. Run the pump at a moderate speed until fluid flows smoothly through the system without air bubbles.
7. Maintenance
7.1 Tube Replacement
The Pharmed BPT tube has a service life of over 1000 hours. Replace the tube when signs of wear, cracking, or reduced performance are observed. Always use genuine Kamoer replacement tubing to ensure compatibility and optimal performance.
- Disconnect power to the pump.
- Carefully open the pump head mechanism.
- Remove the old tubing.
- Install the new tubing, ensuring it is properly seated within the pump head.
- Close the pump head mechanism securely.
- Reconnect power and prime the pump.
7.2 Cleaning
Regularly inspect the pump head and exterior for any spills or debris. Clean with a damp cloth. Do not immerse the motor in liquid. If the pump is used with corrosive liquids, ensure the exterior is cleaned promptly after any spills.
7.3 Lubrication
Periodically check the rollers within the pump head. If the pump does not roll smoothly, especially at low speeds, a small amount of appropriate lubricant (e.g., silicone grease) may be applied to the rollers or the interior of the pump head, ensuring it does not contaminate the fluid path.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not running | No power to control board; Incorrect wiring; Faulty control board or motor. | Check power supply; Verify wiring connections (refer to Section 5.3); Test control board and motor if possible. |
| Inconsistent or no flow | Air in tubing; Kinked or obstructed tubing; Worn pump tube; Incorrect speed setting. | Prime the pump; Check tubing for kinks or blockages; Replace pump tube; Adjust speed on control board. |
| Pump making unusual noise | Dry rollers; Debris in pump head; Motor issue. | Lubricate rollers (Section 7.3); Inspect and clean pump head; Contact support if motor noise persists. |
| Pump head cracking | Material incompatibility with fluid; Excessive pressure; Manufacturing defect. | Ensure fluid is compatible with pump head materials; Verify system pressure is within limits; Contact manufacturer for replacement. |
