Kamoer KPP2 – 12VDC In-0.3-0.5A – B10 Peristaltic Pump
Kamoer KPP2 – 12VDC In-0.3-0.5A – B10 Peristaltic Pump
The Kamoer KPP2 is a compact 12VDC peristaltic pump designed for precise micro-dosing and fluid transfer applications requiring consistent flow rates between 0.3 to 0.5 amperes. This pump is widely used by laboratory technicians, aquaculture professionals, and industrial automation engineers who need reliable, pulse-free liquid delivery in confined spaces. It solves the critical challenge of accurate chemical dosing, nutrient distribution, and sample transfer where traditional centrifugal pumps cannot maintain the required precision or introduce contamination.
Product Overview
The Kamoer KPP2 operates on the peristaltic pump principle, where a rotating rotor with rollers progressively compresses a flexible silicone tube, creating a sealed pumping chamber that moves fluid without direct contact between the pump mechanism and the liquid being transferred. This design eliminates cross-contamination, making it ideal for pharmaceutical, food processing, and laboratory applications. The 12VDC power specification ensures compatibility with standard DC power supplies, solar systems, and battery-backed installations commonly found in remote monitoring stations and autonomous systems.
What distinguishes the KPP2 model is its B10 tubing compatibility, which refers to the specific internal diameter and material composition of the peristaltic tube that determines maximum flow rate and chemical compatibility. The 0.3-0.5A current draw indicates minimal power consumption, making this pump suitable for energy-constrained environments such as IoT-enabled dosing systems, portable field laboratories, and off-grid agricultural operations. The compact form factor and low noise operation make it an excellent choice for integration into automated control systems where space and vibration isolation are critical concerns.

How to Use
Begin by selecting the appropriate B10 silicone tubing and ensuring both inlet and outlet connections are secure and free from kinks or blockages. Insert the tubing into the pump head, aligning it with the roller compression mechanism, and verify that the tube sits properly in the pumping chamber. Connect the 12VDC power supply to the pump terminals, ensuring correct polarity to avoid damage to the internal motor. For initial operation, run the pump for 30 seconds without load to prime the tubing and expel any air bubbles that could affect flow accuracy.
During operation, monitor the current draw to ensure it remains within the 0.3-0.5A specification; exceeding this range indicates excessive back-pressure, kinked tubing, or blockage. For applications requiring precise flow rates, consider using a PWM (Pulse Width Modulation) speed controller to adjust pump RPM and achieve the desired dosing volume per minute. After each use, flush the tubing with distilled water to prevent chemical residue buildup and extend tubing life. Store the pump in a dry environment, and replace the B10 tubing every 6-12 months depending on usage intensity and chemical exposure, as silicone tubing gradually hardens and loses elasticity over time.
Frequently Asked Questions
What is the difference between B10 tubing and other peristaltic pump tube sizes?
B10 tubing refers to a specific internal diameter and wall thickness specification used in peristaltic pumps. The B10 size typically accommodates flow rates in the 0.5-10 mL/min range depending on pump RPM. Different tube sizes (B7, B14, B25) are designed for different flow rate requirements; B10 is ideal for micro-dosing applications. The tubing material, usually silicone, determines chemical compatibility and operating temperature range. Always verify that replacement tubing matches the B10 specification to ensure proper sealing and pump performance.
Can the Kamoer KPP2 be used with corrosive chemicals?
The silicone tubing in the B10 configuration is compatible with many chemicals including weak acids, oils, and alcohols. However, strong bases, concentrated sulfuric acid, and certain organic solvents can degrade silicone over time. Before using the pump with any chemical, consult the silicone chemical compatibility chart or conduct a short-duration test with a small sample. For highly corrosive applications, consider upgrading to PTFE (Teflon) tubing alternatives if available for your pump model, though this may require a different pump head design.
How do I calculate the flow rate of the Kamoer KPP2?
Flow rate depends on three variables: pump RPM, tube internal diameter (fixed for B10), and the number of rollers on the rotor. The formula is approximately: Flow Rate (mL/min) = (Tube Volume per Revolution) × (RPM / 60). For the KPP2 with B10 tubing, the tube volume per revolution is typically 0.5-1.0 mL. If running at 60 RPM, expect roughly 0.5-1.0 mL/min output. To achieve higher precision, use a PWM controller to adjust RPM and measure actual output over a timed interval, accounting for back-pressure effects.
What is the maximum back-pressure the KPP2 can handle?
Peristaltic pumps typically operate safely up to 0.8-1.0 bar of back-pressure before the roller mechanism begins to slip on the tubing, reducing efficiency and accuracy. The Kamoer KPP2 is rated for approximately 0.8 bar maximum. Exceeding this pressure can cause tubing degradation, motor strain, and increased current draw. If your application requires higher pressure, consider using a larger pump model or adding a pressure relief valve downstream to protect the system.
How often should I replace the B10 tubing?
Silicone tubing typically lasts 6-12 months under continuous operation, depending on the chemicals being pumped and operating temperature. Ethanol and oils accelerate silicone degradation. Signs of wear include reduced flow rate, visible cracks or discoloration, and increased leakage around tube connections. For critical applications, inspect tubing monthly and replace every 6 months as preventive maintenance. Keep spare B10 tubing on hand to minimize downtime during replacements.
Can the KPP2 run continuously without rest periods?
Yes, the Kamoer KPP2 is designed for continuous operation in automated dosing systems. However, monitor motor temperature during extended runs, especially in high-ambient-temperature environments. The low current draw (0.3-0.5A) indicates efficient thermal management, but ensure adequate ventilation around the pump housing. For 24/7 operation, verify that your power supply is rated for continuous duty and includes appropriate overcurrent protection.
