Solar Pump and Solar Circulators

Solar Pumps:

It is used in open loop system for the purpose of, to increase the water, or to take the water to the higher position, to the particular height.

Solar Circulators:

Are used in the closed loop system to regulate and circulate he fluid substances for the exchanging of heat, it is used for this reason.

PV Panels:

 

The PV panel provides energy power to (12-VDC) circulators for solar hot water through the system of closed loop; its better known is solar pumps. But you can use any pump for the purpose of collecting heat from the sun. Almost any pump can do the same functioning. As far as the pumps have the ability to control over the high temperature for the long period of time, so it can be use for solar heating system applications. When you need to buy a pump or circulator such quality should be contain in the pump or circulator such as, head pressure, flow rate and energy consumption. The flow rate for the heat obtaining should be lies between (.02 GPM and .04 GPM/Ft²). Of the solar collector surface.

Pumps have a common quality of specified high head pressure and Circulators have high flow rates, but the pump is used to circulate the water through the related system and circulators may be used to pressurize the water. For this purpose. I am using a Taco- 007 pump for the open solar heated drain back system. This taco-007 pump is usually used inside the home heating system to circulate the water. This pumps is enough useful and benefited for me, because water in storage drum only require to reach the specified height of 6′ and the return tube of the water in the related system has a diameter of .75. Because of this the flow is limited and confine to the sufficient extent.

Centrifugal pump as shown in the image you can see it is the example of such pumps (centrifugal means, moving or tending to move from the center, it rotating at very high speed). As shown in the below performance and function chart of the taco-007 pump (003-013). It displays the relation between flow rate and total head pressure. With the help of this chart you can consider and see about the flow rate of Taco-007, it has 5-GPM, when it rose at the height of 9′. And its actual flow rate at the height of 6” is 3-GPM. The reason is that because the total flow head is the resulting sum of the flow head restriction or confinement, and the flow height.

Now you can be better understand the working performance and functioning of the pump. Now for your information let’s take a look at some useful and popular ‘solar pumps’ as below.

These above small pumps can be working with the help of small PV power solar heating water system. To provide power to these excellent and durable pumps you can require a 10 or 20 watts PV-12 VDC power supply for this purpose. But I need to inform you the cost of these useful pumps is between $200 and $400 each. If you are in the state of testing and passing through the condition of experiment of the solar heating system then for your information please check it out these less expensive and affordable alternatives below.

I need to share with you these useful and excellent idea’s about the pumps so that if you need to purchase any pump for you solar hot water system, so that you can take help from these useful and clear information and you can get a fruitful result from your pump in the light of these useful idea’s and suggestions
