Review: Works perfectly - Excellent. Exactly what I was expecting and up to expectations. Recommended for anyone.
Review: Self primed perfectly. Was really happy with this pump and its operation. - Wired this up finally to our commercial trailer for the pot washing sink. Someone had used non-self printing on the trailer and they were not capable if the water container was on the ground. I’m guessing previous owner just sloshed cold in the sink as a work around or just used the hot supply and let it cool? The motor has a little weight to it (but no more than 0.5kg and is a solid construction - you see a lot of the cream coloured pumps advertised on here and they are so light you wonder how long they last. Hook up was easy although it’s a shame they don’t give you the other half of the wiring connector as a pig tail, so it was a cut and strip for me. Connection on the water was by flexible hose and jubilee clips (supplied). Shame it’s not a 1/2inch threaded connections as I do like to use real plumbing fittings but this works for its intended use as it’s not was drinking water. Operation for us is via a push button (as that is what was there before) but pump with auto switch when water demanded according to the small manual that comes with it. First test nothing came through and it took a few pump, stop, pump to fully prime. I opted for a run for 30 seconds the. Wait 30 seconds to avoid motor burn. But it did self prime without any interaction. Once primed it worked every time the button was pressed. Motor is quite noisy but not overly. We have it mounted inside a stainless steel sink cupboard with no door on it and on a trailer, so it has its own acoustic amplifier. We work outdoor festivals so it’s nice for us to hear a confirmation it’s working. Pumped height for us is around 1.25-1.5 meters from the ground and the hose length I had on there is about 2m to the pump and hose in the top opening of a standard 10ltr water container. Was really happy with this pump

## Features

- 【LONGRUN 12V Water Pump】Voltage: 12V DC; Flow capacity: 4.5L/Min; Water pressure: 85PSI. Equipped with quick plug for easy installation. The pressure switch can automatically turn on and off when you turn the faucet on and off.
- 【Smart Overvoltage Protection】Our 12V water pump is equipped with a overvoltage protection. When the maximum water pressure exceeds 85PSI, the caravan water pump would turn off automatically. When the water inlet and outlet return to normal, it will continue to work!
- 【High Quality Copper Motor】Compared with other water pumps, our self priming water pump uses high quality brushed motors with pure copper coils, which are not easy to burn the motor and prolong the life of the product.
- 【Low Noise】Our caravan water pump uses soft rubber mounts with 1 cm diameter support holes. When the high pressure water pump is working, it can effectively reduce the noise caused by vibration.
- 【Wide application】The diaphragm water pumps can be widely used in life and agriculture. Including caravans, campers, boats, garden spray, lawns, outdoor showers, etc.
- 【Note】All LONGRUN water pumps are rigorously tested before leaving the factory, including testing voltage and water pressure items. Therefore, a little water in this pump is normal and will not affect your use. If you have any questions with the pumps, please feel free to contact us.
