Things TO KNOW ABOUT FOUNTAIN PUMPS
出典: くみこみックス
When replacing a fountain pump or deciding on a new one particular, very first there are some crucial terms to maintain in thoughts:
"Head": This is the maximum vertical lift of the pump. For example, a 6' head means the pump is rated to pump water up to 6 feet high. Note, nonetheless, that at 6 feet the pump would be supplying really small water, with gallons per hour around zero. So if you need to have to pump, say, 200 gph at 72", you will most likely want about a 300-600 gallon per hour pump to do the job.
"GPH" : Gallons per hour, typically rated at diverse heights
"GPM" : Gallons per minute, typically rated at various heights
"Pump Curve" : The quantity of water volume "curved" according to various 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 best drinking water forth. When buying a pump for the initial time or when seeking 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 few aspects. A single factor is the size of the pump, as covered above. But you also need to contemplate how wide your tubing will be. Tubing is measured in two ways: inside diameter (i.d.) and outside diameter (o.d.). Very skinny i.d. well water filter tubing will significantly reduce water flow. Several consumers are shocked when they discover that, right after hooking up their 500 gallon per hour pump to 1/two" inside diameter tubing, they are only getting what they contemplate a trickle.
We had an engineer do some calculations for us to illustrate the dilemma. Making use of a 300 gph pump with 1/two" tubing is going to restrict your flow to 253 gallons per hour. By growing the pump to 450 gallons per hour, but still making use of 1/2" tubing, you will enhance volume only slightly, to 264 gallons per hour! The lesson is this: When purchasing a pump, discover out what size of tubing is supposed to go with it. Yet another dilemma is running the tubing also far. Long lengths of tubing develop resistance. If your pump calls for 1/two" i.d. tubing, for instance, but you are running the tubing twenty feet from the pump, it is
a great concept to use 3/four" tubing instead so as not to cut down is alkaline water good for you too much on flow.
How significantly water do I need to have? What size of pump? This question is answered in component by regardless of whether you want a "trickle" or a roar. When you get a fountain, you will generally find a suggested 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 have to deliver 100 gallons per hour at the height you are pumping. So if you are building a 12" wide waterfall that is 3 feet tall, you require to buy a pump that will be pumping 1200 gallons per hour at 3 feet of height. For tiny ponds, whenever achievable, it is a excellent concept to recirculate the water as soon as
an hour, far more typically if possible. Therefore, if your pond is 500 gallons, try to acquire
a pump that will recirculate water at a rate of 500 gallons per hour. For actually
big ponds, this is not essential and is far too pricey.
