Items TO KNOW ABOUT FOUNTAIN PUMPS

When replacing a fountain pump or choosing a new one, 1st there are some key terms to maintain in mind:

"Head": This is the maximum vertical lift of the pump. For example, a 6' head indicates the pump is rated to pump water up to 6 feet high. Note, nonetheless, that at 6 feet the pump would be supplying extremely little water, with gallons per hour about zero. So if you need to have to pump, say, 200 gph kangen water machines at 72", you research enagic will probably require about a 300-600 gallon per hour pump to do the job.

"GPH" : Gallons per hour, usually rated at diverse heights

"GPM" : Gallons per minute, typically rated at distinct heights

"Pump Curve" : The amount of water volume "curved" according to numerous heights. A 500 gallon per hour pump, for instance, may well pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When acquiring a pump for the first time or when searching for a replacement pump, it is vital that you know how a lot of gallons per hour you want to pump and at what height (head).

Water Volume The total volume that you will be pumping is controlled by a handful of variables. A single factor is the size of the pump, as covered above. But you also must take into account how wide your tubing will be. Tubing is measured in two methods: inside diameter (i.d.) and outside diameter (o.d.). Quite skinny i.d. tubing will greatly lessen water flow. Several consumers are shocked when they discover account that, after hooking up their 500 gallon per hour pump to 1/two" inside diameter tubing, they are only acquiring what they think about a trickle.

We had an engineer do some calculations for us to illustrate the issue. Using a 300 gph pump with 1/two" tubing is going to restrict your flow to 253 gallons per hour. By escalating the pump to 450 gallons per hour, but nevertheless using 1/2" tubing, you will increase volume only slightly, to 264 gallons per hour! The lesson is this: When acquiring a pump, discover out what size of tubing is supposed to go with it. An additional issue is running the tubing also far. Extended lengths of tubing develop resistance. If your pump calls for 1/2" i.d. tubing, for instance, but you are running the tubing twenty feet from the pump, it is

a great idea to use three/four" tubing instead so as not to cut down also considerably on flow.

How much water do I want? What size of pump? This question is answered in element by regardless of whether you want a "trickle" or a roar. When you acquire a fountain, you will usually uncover a advised flow. For waterfalls, use this as a rule of thumb: for every inch of stream width or waterfall "sheet," you will need to have to deliver 100 gallons per hour at the height you're pumping. So if you are developing a 12" wide waterfall that is three feet tall, you require to purchase a pump that will be pumping 1200 gallons per hour at three feet of height. For modest ponds, whenever possible, it is a excellent notion to recirculate the water as soon as

an hour, much more typically if possible. Thus, if your pond is 500 gallons, attempt to purchase

a pump that will recirculate water at a rate of 500 gallons per hour. For actually

significant ponds, this is not needed and is far also costly.
