如果您需要稳定的水供应，则需要泵。不管你是真的watering your plants, or whether you’re trying to take a shower. For home applications on a water line, the pump is a large commercial one, run by the water company. For homes with a well system, this is a 230 or 120-volt well pump. For an RV, this means a 12-volt DC water pump. A 12-volt pump will run on your RV’s built-in 12-volt power system, so it won’t require any adapters.
也就是说，并非所有12伏泵都同样精心设计。例如，有些是自我宣传的，而另一些则不是。同样，其他人可以将水泵送到更高的水平，也可以达到更高的压力。结果，重要的是在外出购买任何旧的12伏泵之前进行研究。
We’re about to review three of the best 12-volt DC water pumps on today’s market. We’ll begin with the Shurflo 2088-554-144 Fresh Water Pump. This is a thermally-protected pump with a three-chamber diaphragm design. Next, we’ll check out the Seaflo Water Diaphragm Self Priming Pump. This pump allows for high vertical applications, and is also suitable for marine use. Finally, we’ll examine the Lippert Components 12V Flow Max Water Pump. This pump provides an impressive 50 PSI, which is more in line with normal residential water pressure. Which one is the best for your needs? To find out, we’ll have to dig a little deeper, and consider all of their benefits and potential drawbacks. Only then can we render a fair verdict. Let’s get started!
Features to Look for in a Quality RV Pump
除了基础知识之外，诸如优质的结构，抗振动性和安静的电动机，您还应该寻找什么？首先是确保泵实际上在电力上运行。特别是，您应该避免使用汽油动力或太阳能泵。这些是离网狩猎小屋的绝佳解决方案。但是它们不适合RV，这就是我们今天正在寻找的。
Standard RV pumps run on 12 volts of power, which is the voltage of an overall RV power system. For this reason, it’s essential that an electrical RV pump runs on 12 volts. If you find a 110 or 120-volt pump you really like, don’t buy it. It’s not going to work in your RV. Those pumps are designed for residential use, and generally provide higher pressure. This is needed for residential purposes, particularly where water has to be pumped up to the second floor. A 12-volt pump, on the other hand, will be easy to install and replace your existing RV pump.
So, you need a 12-volt electrical pump. But this is a common specification, and you’ll find a dozen or more at any RV supply store. How do you narrow that down to a more reasonable number? There are plenty of things to look for, but three factors are far more important than others. These are: gallons per minute (GPM), pressure (PSI), and amperage (motor power).
GPM is a measurement of how much water flows through the pipe. For example, if a pump puts out 2.5 GPM, it will provide 2 ½ gallons of water every minute. Most showers and faucets will work just fine around 2 GPM. Keep in mind, though, that you might want to use multiple taps at once. With a low-pressure pump, this can lead to a slow in the flow.
Water pressure is measured in pounds per square inch, or PSI. Residential water systems vary widely, anywhere from 30 to 80 PSI. RV water systems are more standardized, and are designed to handle 40 to 60 PSI. More pressure is good, but more than 60 is very, very bad since it can damage your RV’s plumbing. Steer clear of pumps that advertise high pressure ratings for your RV. It’s not worth the marginally stronger flow.
Amperage measures the strength of the motor itself. Most RV water pumps are designed to draw as little power as possible, since this is a limited resource. However, some high-volume pumps can draw as much as 15 amps. This isn’t nearly as much as a residential pump, but it’s something you should be aware of.
如何更换12伏水泵
Modern RVs come with their own water pumps, so if you’re buying one, it’s either a refit or a replacement. Either way, you’re going to have to roll up your sleeves and get to work. Alternatively, you could hire a qualified RV technician, but they charge a lot, and the replacement is fairly easy. 12-volt DC pumps have a standardized design, so there shouldn’t be a lot of finagling involved.
第一步是关闭供水阀并断开RV的电源系统。这意味着关闭所有断路器，以确保所有电线都死了。现在您干了，没有电流，请找到RV的水泵。删除应该相当简单。输入和输出软管用一对软管夹连接，需要松开。值得庆幸的是，根据螺钉的不同，简单的螺丝刀或可调节扳手将快速完成此任务。一旦软管断开连接，就将泵从其座上拧开。
拆卸的最后一步是切割旧电线。确保记住哪些电线到达哪个连接。最好的方法是拍摄图片，因此您不会混淆任何内容。完成此操作后，您只需举起旧泵，将新泵设置在适当的位置，然后逆转台阶。最好检查旧的软管夹是否生锈，并在必要时更换它们。他们只花了几便士，一个旧的，失败的软管夹可能会破坏您的一天。安装新泵后，恢复电源，重新打开水，然后对其进行测试。假设一切都正确地连接，您应该很好！
Shurflo 2088-554-144Fresh Water Pump
TheShurflo 2088-554-144Fresh Water Pumpis designed to run as quietly as possible. Its standout feature is its large, stainless steel base with fat rubber shock-absorbing bushings. When the pump is screwed down, these bushings will compress, providing excellent vibration absorption. As a result, noise transfer is kept to a minimum, and remains in the pump compartment, where it belongs. The overall size of the Shurflo pump is 10.3 inches long, 6 inches high, and 4.7 inches thick. It weighs 5.1 pounds, surprisingly light for the size and power.
内部泵是一个正排量的三腔设计。我们不会太深入该泵的技术方面，而是足以说明它有效。您在45 psi时获得3.5GPM的流量。电动机使用永久磁铁提供连续的水流，并受到热保护以防止损坏。像我们列表中的其他泵一样，Shurflo可以在任何12伏电源上运行。也就是说，它旨在连接，而不是使用12伏插头。如果您想从一个power station, you’re going to need an adapter.
The Shurflo pump has a built-in check valve, which prevents reverse flow. This means it’s safe to use with a plumbed toilet, since no tank water will return through the valve. Not only that, but it’s available in a one-pack, a two-pack, or a four-pack. This isn’t helpful for RVs, but it has its own applications. For instance, if you want to supply an off-grid house, you can run four pumps simultaneously.
Seaflo Water Diaphragm Self Priming Pump
TheSeaflo Water Diaphragm Self Priming Pumphas a similar diaphragm design to the Shurflo pump. This means it’s capable of continuous flow, which is what you want from an RV pump. The overall size of the unit is a bit smaller, though. It’s a bit shorter, at 7.84 inches, and the 5-inch height is less, as well, although the thickness is basically the same. At 4.62 pounds, the weight is very similar, and it has a standard mounting configuration. After the Shurflo pump’s sturdy base, the plastic mounting base was a bit disappointing. It won’t absorb vibration quite as well as the Shurflo.
That said, the Seaflo has some distinct advantages. For one thing, it’s self-priming, and can support a 6-foot vertical run. It can also run dry without getting damaged, which is a huge concern when you’re priming. The water capacity is 3 GPM, which is quite reasonable, and the pressure is a respectable 45 PSI.
Seaflo聚氨酯的主要景点mp is its ability to support marine applications. To this end, the kit includes a pair of ½-inch barbed hose adapters, as well as a mesh inlet strainer. Simply install these adapters and you’re ready to hook into your boat. This is all protected by a four-year manufacturer’s warranty, one of the best in the business. If there are any failures during that time period, you’ll receive a refund or a replacement.
Lippert Components 12V Flow Max Water Pump
TheLippert Components 12V Flow Max Water Pumpis designed for maximum pressure. It outputs at an impressive 50 PSI, while maintaining 3 GPM of water flow. This means more powerful showers that feel like you’re in a full-sized house. Not only that, but it’s capable of self-priming, and can run dry without burning out. This makes it suitable for non-RV applications where water supply may be intermittent.
尽管如此，流量最大的大小并不太大。它长10.5英寸，高六英寸，厚5.5英寸。4.5磅，它轻巧且易于安装。公平地说，塑料底座并不能在吸收振动方面做得最好。没有橡胶衬套，但仍然比金属金属更好。
The motor draws 9.5 amps, so it’s reasonably powerful without drawing an excessive load. It’s also corrosion-resistant, so a little leakage isn’t the end of the world. Finally, the pump itself is rated to sustain multiple freeze-thaw cycles. Obviously, you shouldn’t intentionally let the pump freeze with water inside. But accidents happen. When they do, it’s good to know your housing hasn’t been cracked.
Final Verdict
Clearly, any one of these pumps would make a suitable replacement for most RVs. That said, there are still some important differences to take into consideration. For instance, we started out by reviewing theShurflo 2088-554-144Fresh Water Pump. This pump’s main advantage is its high rate of water delivery. At 3.5 GPM, you can run two faucets simultaneously without any significant drop in pressure. Even with this large delivery capacity, the Shurflo pump runs quietly. Rubber bushings prevent it from transferring a lot of vibration to the rest of your vehicle. It’s also available in a two or four-pack if you want to run multiple pumps simultaneously.
TheSeaflo Water Diaphragm Self Priming Pump, as its name implies, is a solid choice for marine applications. Because it can self-prime over a six-foot vertical, it’s great for boats and other similar uses. The barbed connection adapters are easy to attach, as is the mesh inlet strainer. Admittedly, the Seaflo is a bit louder than the Shurflo. But if you need self-priming performance and a marine rating, it’s a great choice. Not only that, but the four-year manufacturer’s warranty provides an excellent added value.
TheLippert Components 12V Flow Max Water Pump有两件事使它与其他事物区分开来。首先，它以50 psi的价格提供水。尽管平均3.0 GPM流量，但这给它带来了更多的住宅感觉。其次，它可以抵抗冰冻和解冻。这使其适用于极端环境，因为意外冻结是一个问题。将其与功能强大的自我播放的9.5-AMP电动机相结合，您拥有出色的泵。
