Product description:

Product: Solar water pump

Model:L3D-20-80


Appilication:

surface pump

for surface water of pond, river, lake

for irrigation of a big farm with 12000 m2 on the top of a small hill


Product specification:

flow rate:20m3/ hour, 160m3/day.

lift: 10m-80m

pump diameter: 296mm

Pump installed on the ground, outlet to the water surface:4m

with AC motor, motor power:5.5kW

but only need solar power:3.2kW(while Grundfos pump needs at least 11.5kW solar power, our pump can save more than 50% solar panel power,save USD3600 cost for solar panel per set.

Q:The problem of installing pressurized water pump in solar hot water outlet pipe
, the installation of pipe weight should not be added to the pump, so as not to pump deformation.
Q:Solar water heater before the booster pump is now changed into tap water how to get
You can then install a water tank on the top of the three, you still have to use the water pump to the water tank inside, so the effect is the same, might as well not change.
Q:Will the next solar hot water system, the solar energy pump how to select the number,
And the total length of the circulation pipe to determine the circulation diameter, and then calculate the pipeline along the road loss (the general pipeline loss is not more than 10 meters is appropriate); according to the tank to the collector overflow vertical distance calculation static pressure difference.
Q:What is the pump for solar hot water
If it is by way of manual pressurization, then it is more, all in line with the head of the flow of hot water pump can be.
Q:Booster pump installed in the solar water heater, the correct location should be where the solar water heater?
After the solar energy should be pressure type, the water by the pressure of the tap water out of the top, there is no such trouble.Now some manufacturers have produced a pressure of fresh water solar energy, not only pressure red, water quality is good, you can drink solar energy.
Q:What is the role of solar water pump?
Compatibility is good, photovoltaic power generation can be used in conjunction with other energy, can also be based on the need for photovoltaic systems is very convenient capacity.
Q:Does the balcony wall - mounted solar energy require a circulating pump?
Now the mainstream balcony wall is a natural cycle, so do not need to install the circulating pump. Circulation pump is used to do the forced circulation. The so-called natural circulation, is your home balcony collector (flat collector or U-tube collector) to absorb solar light heat, the collector medium using cold water sink hot water floating automatically heat will be passed to the tank in. If your collector is higher than the tank, or because the pipeline climbing and other reasons can not be a natural cycle, it is necessary to increase the circulating pump. Solar energy in the natural cycle of the best, plus the pump is not good. Waste money, and easy to bad, if the bad quality and noise.
Q:What is the difference between centrifugal pumps and circulating pumps?
Under normal circumstances, the circulating pump head is low, up to 2 meters, while the flow is large, up to thousands of cubic meters / hour.
Q:How does the solar self-priming pump be installed?
1. Pump through the long-distance transport to reach the use of the scene, before installation to check the machine parts are intact, fasteners should be fastened to check the pump shaft and motor shaft concentricity, if the shift should be corrected.
Q:How to use solar panels to drive 50W of circulating water pump, what configuration needs, how to connect?
Stable, you must control the output of the battery, try to use a peak 30V-36V, peak current 2A-3.5A battery power supply, so even if it is cloudy, the battery will output at least 1.5-2A, according to you
