When replacing a fountain pump or choosing a new 1, very first there are some important terms to maintain 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, nevertheless, that at 6 feet the pump would be delivering very tiny water, with gallons per hour about zero. this page is not affiliated So if you require to pump, say, 200 gph at 72", you will most likely require about a 300-600 gallon per hour pump to do the job.

"GPH" : Gallons per hour, normally rated at different heights

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

"Pump Curve" : The amount of water volume "curved" according to different heights. A 500 gallon per hour pump, for instance, may pump 500 gallons per hour at " lift, 350 gallons per hour at 24" of lift, and so forth. When acquiring a pump for the 1st time or when searching for a replacement pump, it is essential 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 factors. One particular aspect 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 approaches: inside diameter (i.d.) and outside diameter (o.d.). Extremely skinny i.d. tubing will significantly lessen water flow. Numerous customers are shocked when they discover that, following hooking up their 500 gallon per hour pump to 1/2" inside diameter tubing, they are only finding what they consider 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 increasing the pump to 450 gallons per hour, but still using 1/2" tubing, you will increase volume only slightly, like i said to 264 gallons per hour! The lesson is this: When purchasing a pump, find out what size of tubing is supposed to go with it. Yet another difficulty is operating the tubing also far. Extended 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 idea to use 3/four" tubing instead so as not to life ionizer 8100 cut down also much on flow.

How a lot water do I need? What size of pump? This question is answered in part by regardless of whether you want a "trickle" or a roar. When you buy a fountain, you will normally discover 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 deliver 100 gallons per hour at the height you're pumping. So if you are creating a 12" wide waterfall that is three feet tall, you need to buy a pump that will be pumping 1200 gallons per hour at 3 feet of height. For small ponds, whenever possible, it is a good thought to recirculate the water once

an hour, a lot more usually if possible. Therefore, if your pond is 500 gallons, attempt to purchase

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

significant ponds, this is not required and is far also expensive.
