Things TO KNOW ABOUT FOUNTAIN PUMPS
出典: くみこみックス
When replacing a fountain pump or picking a new a single, first there are some key terms to keep in thoughts:
"Head": This is the maximum vertical lift of the pump. For example, a 6' head signifies the pump is rated to pump water up to 6 feet high. Note, even so, that at 6 feet the pump would be supplying very small water, with gallons athena water ionizer per hour around zero. So if you need to pump, say, 200 gph at 72", you will almost certainly need about a 300-600 gallon per hour pump my whole home water filter to do the job.
"GPH" : Gallons per hour, normally rated at diverse heights
"GPM" : Gallons per minute, generally rated at distinct heights
"Pump Curve" : The amount of water volume "curved" according to numerous heights. A 500 gallon per hour pump, for instance, might pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When getting a pump for the initial time or when in search of a replacement pump, it is crucial that you know how several 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 couple of factors. A single aspect is the size of the pump, as covered above. But you also ought to take into account how wide your tubing will be. Tubing is measured in two approaches: inside diameter (i.d.) and outdoors diameter (o.d.). Very skinny i.d. tubing will drastically lessen water flow. A lot of buyers are shocked when they find that, following hooking up their 500 gallon per hour pump to 1/two" inside diameter tubing, they are only acquiring what they take into account a trickle.
We had an engineer do some calculations for us to illustrate the issue. Making use of a 300 gph pump with 1/two" tubing is going to restrict your flow to 253 gallons per hour. By increasing the pump to 450 gallons per hour, but still making use of 1/2" tubing, you will improve volume only slightly, to 264 gallons per hour! The lesson is this: When buying a pump, locate out what size of tubing is supposed to go with it. An additional difficulty is operating the tubing as well far. Lengthy lengths of tubing generate resistance. If your pump calls for 1/two" i.d. tubing, for instance, but you are life ionizer 9200 running the tubing twenty feet from the pump, it is
a great thought to use three/four" tubing rather so as not to reduce down as well significantly on flow.
How considerably water do I require? What size of pump? This query is answered in element by no matter whether you want a "trickle" or a roar. When you acquire a fountain, you will normally find a advised flow. For waterfalls, use this as a rule of thumb: for each and every inch of stream width or waterfall "sheet," you will need to deliver 100 gallons per hour at the height you're pumping. So if you are building a 12" wide waterfall that is three feet tall, you need to acquire a pump that will be pumping 1200 gallons per hour at 3 feet of height. For small ponds, anytime attainable, it is a very good thought to recirculate the water as soon as
an hour, more often if achievable. Thus, if your pond is 500 gallons, try to get
a pump that will recirculate water at a rate of 500 gallons per hour. For truly
significant ponds, this is not necessary and is far as well costly.
