An electric motor drives a flexible diaphragm via an eccentric cam, alternately drawing in and expelling liquid. Since no rotating parts operate directly in the liquid, the pump handles minor contamination well.\u003c\/p\u003e \u003cp\u003eThe self-priming function allows the pump to start even when the intake hose is initially filled with air. Manual priming before operation is not required. With a flow rate of 1 to 3 liters per minute and a maximum delivery head of 3 meters, the pump is suitable for small to medium liquid volumes in compact systems.\u003c\/p\u003e \u003cp\u003eThe motor requires more current when starting than the digital outputs of microcontroller boards can provide. It must therefore be controlled via a relay or a dedicated motor driver module connected between the control board and the pump's two blade terminals. This allows you to build automatic irrigation systems, small aquariums, or water circuits for cooling projects.\u003c\/p\u003e \u003cp\u003eThe pump can handle water as well as other liquids within the specified temperature range. A critical point is continuous operation without a liquid supply, which can cause diaphragm and motor damage. The pump requires a separate power supply and a relay or motor driver module for control.\u003c\/p\u003e \u003ch3\u003eSafety Information\u003c\/h3\u003e \u003cp\u003eThe pump must not run without liquid. It is intended exclusively for building prototypes and for testing and development purposes, and is not designed for installation in the household electrical circuit. If you have questions about the power supply or control, consult a qualified electrician before commissioning.\u003c\/p\u003e \u003ch4\u003eScope of Delivery\u003c\/h4\u003e \u003cul\u003e \u003cli\u003e1x R385 Water Pump - 6-12V\u003c\/li\u003e \u003cli\u003e2x Mounting Brackets for R385 Water Pump\u003c\/li\u003e \u003c\/ul\u003e","brand":"Funduino","offers":[{"title":"Default Title","offer_id":65998303396189,"sku":"F23107429","price":3.78,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1074\/5649\/5965\/files\/r385-wasserpumpe-6-12v-funduino-9881240.png?v=1791496456","url":"https:\/\/funduino.com\/en\/products\/r385-water-pump-6-12v","provider":"Funduino","version":"1.0","type":"link"}
