Hi I have a 800 gal pond with easypod filter and 6000 litre per hr allpondsolution pump with dual inlet . in GPM SG = specific gravity. Pump Head vs Flow Rate – What’s The Difference?

// ]]>. document.TDHCalcForm.tankPressure.disabled=false;

Injector Flow Rate* Base Fuel Pressure .

Flow (LPH) @ Pressure (PSI) *Injector flow rate must represent the flow rate at your base pressure. Enter total pumping lift or height (feet) water is pumped vertically.

var GPM= form.GPM_form.value*convertFlow[form.flowUnit.options.selectedIndex]; For more exact calculations, you can use a friction loss chart. Pump Sizing does the hydraulic calculation for a centrifugal pump and estimates differential head, hydraulic power, motor power, NPSH available.

the hose to the pond head is 3 foot with one 90 degree turn, He thinks , because he is indecisive, that a moderate flow would be good.

When sizing a pump for circulation, the most important factors are the volume of your pond and the amount of fish you have. Using a thinner pipe is a waste of your pump’s power and can even damage certain setups.

Pumps don’t supply the same flow rate in every situation. To estimate volume in gallons, multiply your pond’s length * width * depth * 7.5 (measure in feet for this formula). Flow = Gallons Per Minute. You can use pumps’ max head heights to compare how strong they are.

Check your car manual to find the correct tyre pressure, and use our convertor tool if the measurements don't match the pump. Next, find your fountain’s head height by measuring the vertical distance from the outlet to the height at which the pump sits.

You may need to include pressure head if your pump is going to power a pressurized filter, UV clarifier, or spray nozzle. var str = input.value; (form.pipeDiam_form.value == null || form.pipeDiam_form.value.length == 0) ||

I’d be happy to try to help you here.

[CDATA[ Pumps come in a variety of sizes and strengths, and the type you choose should depend on what you need it for. Pressure head is the resistance from devices that use pressure to operate.

Also, many filters can’t handle the flow rates that waterfalls and fountains require. We provide hydraulic components & repair services for industrial applications like paper mills, saw mills, steel mills, recycling plants, oil & gas applications and mobile applications, including construction, utility, mining, agricultural and marine equipment.

Skimmer doesn’t seem to work nor the filter.

However, we cannot assume any responsibility for errors. function checkNumber(input, min, max, msg)

use this hydraulic pump horsepower formula: Example: The input horsepower required for a pump that needs to provide 10 GPM at 2000 psi is: Calculated out this gives an input horsepower requirement of 11.67 horsepower. The average pressure in a domestic water system with a pressure tank used; or the pressure that is required for an application if a pressure tank is not used (e.g.


pressure = form.tankPressure.value/pressureConst[form.pressureUnit.options.selectedIndex]; var ch = str.substring(i, i + 1)

Equipment like filters, waterfalls, and fountains each need specifically sized pumps to function well. If your pond is densely stocked, your pump should circulate the entire volume of water every hour.

Fuel pump FLOW -NA (Petrol) 0. Manufacturers usually list the flow rates their pumps provide at several head heights. He wants to put in a waterfall with an 8 inch spillway that sits one foot above the surface of the pond water. I have 2-gold fish ponds approx. © 2020 Tuhorse Pumps - USA and Canada Store, Shipping, Cancellations, Warranty, Refunds. To size a pump, you need to consider two important numbers: flow rate and head. Keep in mind that these are often intended for professional landscapers.


how can you calculate a pump requirement for a water pumping system in the following arrangement. p = 0.433 h SG (1) Whats your opinion.

} Example . The formula used in the calculation process is [ (Head (Ft.) X S.G.)/2.31].

These general guidelines are useful for understanding what flow rate and head height can tell you about a pump. Could I ask what type of filter box you have (pressurized or non) and at what height the filter is above the water level? Bar.


//unit conversion factors All formulae for finding the amount of fluid that will flow through a hose at a given time, are approximate.

Psi. { Still, there are a couple of easy ways that all pond owners can limit friction head. { You may decide to use separate pumps for your filter and water features. Pressure = Pounds per Square Inch .

My gph flow rate is going to be only about 150 since the pond is 18 inches deep and i will be using a fountain with no other features. Below, we’ve laid out some specific details about sizing pumps for water features, and for filtration and circulation. Address: 1519 Hwy.


As filters become dirtier or clogged, less water can pass through them, increasing the pressure.


var pipeDiam = form.pipeDiam_form.value*convertInchMM[form.diamUnit.options.selectedIndex]; if(document.TDHCalcForm.tankUse.checked) Also would like to use the fountain with 1” tube. The first step in sizing a pump is finding the flow rate you need. If it’s the main system, could you let me know the rough volume of the pond?

I have a pond that is 11ft x8ft x3ft.

(Flow Definitions), 2) Total Dynamic Head (TDH) & Friction Head. } i need to learn also. Formula: HP = PSI * GPM / 1714 PSI is gauge pressure in pounds per square inch; GPM is oil flow in gallons per minutes.

function ConclusionBox(value){

For ponds with lighter stocks (or no fish at all), pumps that move half the volume may be enough. (form.diffElev_form.value == null || form.diffElev_form.value.length == 0)) return false; To find the right balance, look for a pump that comes close to, but doesn’t exceed, your filter’s maximum suggested flow rate. We want to see your websites and blogs.

one is located 2ft higher then the other and 3ft apart. I have a 250 gallon pre formed pond with 3 ,8 inch shubunkins. calculateTDH(input.form); Stronger pumps can supply larger flow rates at higher amounts of head. # of Injectors . Together, they tell you how much water a pump can move and how much resistance it can overcome. Remember to add 1 foot of head for every 10 feet of pipe that will connect the pump and waterfall. var num = 0 + str
