2 Pcs R365 Micro Diaphragm Pump 5V 2.2L/Min Self Priming Water Air DC Motor

Quiet and Compact Micro Diaphragm Pump for Small-Scale Projects This set of two R365 micro diaphragm pumps delivers a practical and dependable solution for a range of DIY, hobby, and remote water or air transfer tasks. Each pump offers a maximum flow rate of 1.5 to 2.2 litres per minute and a nozzle size of 9mm, making it well suited to compact setups where space is limited. With a self-priming design and a lift capability of at least two metres, the pump is easy to position and quick to get working, even in awkward spots. Powered by a standard 5V DC supply, the pump works flexibly with common power sources such as USB adapters, power banks, and standard batteries. This makes it particularly convenient for portable builds, temporary installations, or projects where mains power is not readily available. The low pressure requirement of 5 psi or above keeps operation straightforward and energy efficient. Designed with quiet running in mind, the pump produces less than 65db when measured from 30cm away, helping to keep noise to a minimum. This is a thoughtful feature for anyone using the pump near aquatic pets, where a calm and undisturbed environment matters. The efficient motor also supports lower power consumption, which is a useful benefit for battery-powered or solar-powered arrangements. Built from durable materials, the pump is made to last. The motor casing uses stainless steel for corrosion resistance and reduced rusting, while the pure copper coil provides strong, smooth performance with low heat generation. The pump body itself is made from food-grade silicone, offering better heat resistance and stable operation over time. These material choices combine to give a reliable component that performs consistently without unnecessary wear. Whether you are working on a water circulation system, a small fountain, or a custom air or liquid transfer project, this pair of pumps offers a compact, quiet, and versatile option. Their straightforward power requirements and dependable construction make them a sensible addition to any maker’s toolkit.
