12V NKP Mini Self-priming Peristaltic Pump (5W, Silicone Tube)
Compact DC Peristaltic Pump for Precise Liquid Transfer
This NKP series micro peristaltic pump uses a rotating roller to squeeze a silicone tube, moving liquids without any contact between the pump mechanism and the fluid [citation:5][citation:9]. It is self-priming and can run dry without damage, making it suitable for applications like water sampling, dosing, and ink circulation [citation:4][citation:9].
SelfPriming & Fluid Isolation The pump can self-prime and the fluid only touches the silicone tubing, preventing contamination [citation:4][citation:9].
Compact & Low Power - Consumes only 5W and has a small footprint, making it suitable for portable and embedded projects [citation:2][citation:6].
Operating Voltage: 12V DC (also compatible with 6V-24V depending on the specific model) [citation:2][citation:3][citation:6].
Flow Rate: 10 to 60+ ml/min depending on the motor and tubing size (e.g., S04 tubing gives 10ml/min, S08 tubing provides 60ml/min) [citation:2][citation:5][citation:6].
Typical Current: Around 0.25A [citation:7][citation:10].
The pump typically uses 3 rotors to minimize pulsation in the flow [citation:4][citation:8].

= Applications =
- Peristaltic pumps are widely used in applications requiring sterile or precise fluid handling, such as laboratory dosing and medical devices [citation:7][citation:9].
- They are commonly used in aquariums, water circulation systems, and inkjet printers [citation:3][citation:8].
- The pump can be controlled via a simple power switch or with a PWM signal for speed regulation [citation:5]. It is also compatible with Arduino and Raspberry Pi projects [citation:9].
The silicone tube can be easily replaced, extending the pump's usable life [citation:4].
√ Tube replacement is simple and quick.
√ Forward and reverse rotation is possible by reversing the DC polarity [citation:4][citation:12].
