Kamoer NKP-DA-B08 24V Peristaltic Pump, Brushed Motor, 48ml/min

The Kamoer NKP-DA-B08 is a peristaltic pump, a design that moves liquid by squeezing a flexible silicone tube in a rolling motion rather than pushing the fluid through any part that actually touches the motor or gearing. That matters directly for agricultural spraying and any application handling chemicals, fertilizers or anything mildly corrosive or abrasive, since the liquid never contacts a metal impeller, bearing or seal the way it would in a centrifugal or diaphragm design, which avoids corrosion and simplifies cleaning between different chemicals.

Running on 24V DC with a brushed motor, the pump delivers up to 48ml per minute, a precise, low-flow rate suited to metered dosing rather than bulk transfer. Kamoer recommends controlling speed via a PWM signal, letting flow rate be dialed in electronically rather than through a mechanical valve, which is the standard approach for integrating a pump like this into an automated or remote-controlled system such as a drone spray controller.

Because only the tube itself contacts the liquid, maintenance is straightforward: a worn or chemically degraded tube is simply replaced rather than the whole pump being serviced or rebuilt, and switching between different liquids mostly just means swapping the tube rather than worrying about residual contamination in pump internals. Kamoer's listed strengths for this design include high flow consistency, strong negative pressure (self-priming) capability, easy maintenance, chemical stability, long service life, and high repeatability from one dosing cycle to the next.

Listed applications include laboratory and research use, experimental setups, packaging and filling lines, and the food industry, alongside the agricultural dosing role it fills on a spray drone. For precise, chemical-safe liquid metering where a diaphragm or centrifugal pump's wetted metal parts would be a liability, the NKP-DA-B08's peristaltic design is the more appropriate choice.
