The pond pump is truly the "heart" of the pond. They are needed for a variety of functions - from the general circulation of the game of running water. The good news is that there are a multitude of pond pumps available from reputable manufacturers. For almost all applications will have different products to choose from. The bad news is choosing the right pump for your needs can be a very difficult task. This article will give you a solid foundation to offer the possibilityright pump for your application pool.
Types of pumps pond
Submersible pond pumps are installed completely submerged under water, usually in the deepest part of the pond. This class of pump is generally suitable for small ponds or lakes that are less than 4000 GPH. The main advantage of submersible pumps is that they are inconspicuous and are very quiet. They are also very easy to install, just make sure that the cable length is sufficient for your needs.The disadvantages of a submersible pump, pond pump, is that they are often removed from the pond for cleaning and maintenance. You have to use more expensive and usually as a pump outside the pond, although there have been some significant improvements recently in the field of energy efficiency submersible pump.
External Pumps: As the name suggests, external pond pumps are designed to be installed outside the pond, or "in-line". Pond pumps are the best choice for external medium and large ponds. Their, The largest water flows (4000-10000 GPH) to manage and less expensive to operate. Other advantages of an external pump include easy maintenance, longer life expectancy and the ability to replace parts, such as external pumps are not encased in resin, such as a submersible pump. It is to the downside, an external pump takes more time and effort for installation, must be camouflaged from view, and are usually more expensive than submersible pump pond.
Pumps Direct Drive: Direct Drive Pond Pumpsexternal pumps are more common, as they prefer the option of watering. Direct Drive pumps are suitable for applications that require a significant amount of head height - such as pumping water uphill for a waterfall. They are generally more expensive than a pond pump magnetic drive to work, but in many cases the choice only when a significant amount of water flow is needed. If you are buying a submersible pump to direct drive pump, make sure it is oil-free, asOil spills can harm plants and fish pond water. Magnetic drive pumps: Magnetic Dive pond pumps (or pumps MAG) are generally designed as a submersible pump, since most are not able to draw water from the pump. Power is supplied via an electromagnetic field, the fan runs created. Their main advantage is energy efficiency and durability. In addition, magnetic drive pumps pond easy to repair, as is usually all that is needed is a magnetic shaft and the impeller (the only moving parts).The disadvantages are that may not have sufficient water volume for high head applications, and are slightly more expensive than direct drive pumps pond. In general, if you do not watch more than an arduous task, and head for a submersible pump, pond pump is the magnetic hard disk is the best choice.
Air Pumps: Air Pumps Pond has no water flow. You suck air in the pump then spread into small vesicles. Air pumps are the most commonly used pond for the winter, since they have aOxygen supply and gas exchange, without the provision of water flow.
Choosing the right pond pump size
To select the correct size pump pond, first determine the correct category application: 1) filtration and recirculation, or 2) water games.
Filtration and recirculation operation: The rule of thumb for circulation and filtration applications, the pump should turn the pond water at least once every two hours and, ideally, once per hour. For example, if the lake is 3000Gallons is the ideal size is 3,000 GPH pump, but not less than 1,500 GPH. My personal preference is always high end. A flow pump can always be a bit 'limited, but it never increased. Also, make sure the pump is the right size for your pond filter specifications.
Water quality: Choosing the correct size pump for a water feature is a bit 'more complicated. The first step is to determine the amount of water brought to the extraction point of the function of water neededitself. Let us have a waterfall as an example because this is the most common water. For every inch of waterfall width of 100-150 GPH you need. So if you have a 14 "wide waterfall dam are, you need to 2,100 GPH 1400 GPH of water over the edge of the dam.
The next step is to calculate the height of the head. Height of the head refers to the journey, the approximation of horizontal and vertical distance from the water pump at the top of the waterfall is. Horizontal distance is calculated at aRatio of 10:1, while the vertical distance is calculated at a ratio of 1:1. For example, if the horizontal distance from the pond waterfall pump 30 ', this corresponds to 3' height of the head. If the vertical distance from the pump to the top of the waterfall is 7 ', equivalent to 7' height of the head. Therefore, the entire head height for this application is 10 '.
The final step is to check with the manufacturer's performance curve for the type of pump you choose to have in order to determine the appropriate size of the pump.Let the pump unit Cal in May as an example. The model is PWM3900 to 4,100 GPH of water flow rated pump, but has a capacity of 2280 GPH of water flow in a 10 'head height. This would be a good choice for this particular example. Remember, it's always better to err on the upper side of the GPH, because this would put less pressure on the pump.
