RS PRO Direct Coupling Water Pump, 6 V to 28 V, 4 Bar, 1100 ml/min


If you need a pump that can handle high and low pressures, turn to this one from RS PRO. It's self-priming, so it starts up reliably each time you use it. As it's compatible with most fluids, you can install it in a wide range of equipment, including cooling and lubrication systems.


As the pump is CNC (computer numerical control) machined to precise dimensions, it's guaranteed to deliver reliable performance. Thanks to its durable aluminium construction, it's highly resistant to corrosion and will last a long time.


This type of pump is suitable to use as a high-pressure fuel pump. It has an IP45 rating, so it's protected against dust, dirt and sand, as well as submersion in 1.5 m of water for up to 30 minutes.
