The pond pump is truly the "heart" of your pool. Are needed for a variety of functions - from traffic characteristics general water supply. The good news is that there is a wide variety range of pond pumps available from most manufacturers known. For almost all purposes, Several products are available to choose from. The bad news is to select the pump for your needs can be a very difficult task. In this article we provide a solid basis to select the right pump for your application pool.
types of pumps Pond
Submersible pumps: submersible pumps tanks are installed completely under water, generally in the the deeper the pond. This kind of pump is generally suitable for small ponds, water features or that require less of 4,000 GPH. The main advantage of a submersible pump is that they are visually unobtrusive and run very slowly. They are also very easy to install, just the length of cable is sufficient for their needs. The disadvantages of a submersible pond must be frequently removed from the lagoon cleaning maintenance. They also are generally more expensive to operate an outdoor pond pump, although it has recently been some improvements significant energy efficiency of the submersible pump.
external pumps: As its name implies, a pond external pumps are designed to be installed outside of the lagoon, or "online". External pond pumps are a better choice for medium and large ponds. They can handle greater flows of water (4.000 to 10.000 gallons per hour) and are less expensive to operate. Other advantages of an external pump include ease of maintenance, longer half-life, and the ability to replace parts of pumps outside are not locked into the resin as a submersible pump. On the negative side, an external pump requires more time and effort to install, must be hidden from view, and are generally more expensive than submersible pumps pond.
Direct-drive pumps: Direct Drive Pond Pumps are the most common external pumps because they have the ability to draw water for them. Direct Drive pumps are suitable for applications which require a significant amount of head height - such as pumping water upstream from a waterfall. They are generally more expensive than a magnetic drive pump pond, but in many cases the only option when a considerable amount of water flow is necessary. If you buy a direct drive submersible pump, make sure it is free from oil, such as leaking badly fish oil pond and aquatic plants. magnetic drive pumps, magnetic pumps scuba tank (or Mag-drive pumps) are generally designed as submersible pumps as most are unable to draw water at the pump. Power is created through an electromagnetic field that turns the wheel. Its main advantage is energy efficiency and longer life. In addition, Mag Drive Pond Pumps are easy to repair in general all that is needed is a magnetic axis and the rotor (the only moving parts). The disadvantages are that it can provide sufficient water flow applications for head high, and are slightly more expensive direct-drive pumps pond. In general, if you do not have a requirement for head and looking for a submersible pump, pump drive pond MRI is the best option.
Pumps Air: Pond Pumps Air does not provide the water flow. Removed from the air pump, and disseminating small bubbles. The air pumps are the most commonly used for the pond in winter and providing oxygenation and gas exchange, without providing water flow.
Choose the right size of pond pump
To choose the size of the pond pump right, first place to determine the category the correct application: 1) filtration and recycling, 2) Characteristics of water.
Filtration and recycling: The rule General for the purposes of filtering and recirculating pump should turn the pool water for a minimum of once every two hours, ideally once per hour. For example, if the pond is 3,000 gallons of the size of the ideal pump is 3000 gallons per hour but not less than 1,500 liters per hour. My personal preference is always to err on the high side. A flow rate of the pump can still be a bit limited, but never again. Also, make sure the pump is properly sized to your specifications pond filter.
water features: Choice of pump size correct for a source of water is a little more complicated. The first step is to determine how much water flow you need discharge point of water itself function. We will use a waterfall as an example because it is the source of more water. For each inch of width cascade requires 100 to 150 gallons per hour. Therefore, if you have a 14 "wide waterfall rids 1400 GPH to 2100 GPH of water flow on the edge of the dam.
The next step is to calculate the height of the head. Head height refers to the approximation of the vertical water and horizontal distance to travel from the pump to the top of the waterfall. horizontal distance is calculated using a ratio of 10:1, while the vertical distance is calculated using a ratio of 1:1. For example, if the horizontal distance from the pond pump waterfall is 30, equivalent to 3 'height of the head. If vertical distance between pump up the waterfall is 7 ", equivalent to 7 'of head height. Therefore, the total height of the head of this application is 10 '.
The last step is to examine the manufacturer's power curve for the type of pump you have chosen to determine the size corresponding pump. We'll use the camera Cal Mag pump as an example. PWM3900 model is estimated to 4,100 GPH of water flow in the pump discharge, but has a capacity of 2,280 gallons per hour of water flow to the head height of 10 '. It would be a good choice for this example particular. Remember it is always best to err on the upper end GPH range, which puts less pressure on the pump.
