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.


Material:

Pump inside: stainless steel and wearable nylon,it enables our solar pump to have 10 years sevice life.

Motor : AC motor, 380V , three phase , 50Hz. The pump also can connect with grid power directly.


Certification:

3 International patent

ISO9001

CE


Warranty:2 years

Q:Will the next solar hot water system, the solar energy pump how to select the number,
Generally need to calculate the total flow according to the collector area, a reasonable division of the branch and divided by the number of branches to calculate the branch flow, according to the collector test report on the flow resistance curve calculation and series calculation of the collector pressure drop;
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?
Often, it is not possible to clearly delineate the obvious boundaries of the two pumps you are talking about.
Q:What is a photovoltaic pump?
The type of photovoltaic water pump (1) solar photovoltaic pump (2) solar photovoltaic permanent magnet synchronous pump. The characteristics of the PV pump: PV water pump system fully automatic operation, without manual duty, the system mainly by the PV flood inverter, photovoltaic array, pump composition. The system eliminates the storage of energy storage devices such as batteries to replace water storage capacity, direct drive pump water.
Q:On the issue of pumps and solar panels
Pump head and power sure and pump power and methods such as centrifugal pumps ~ but this full business can give you recommended.
Q:How to use solar panels to drive 50W of circulating water pump, what configuration needs, how to connect?
Of the 24V motor 50W, it takes about 2A current.Therefore, the output current of the battery plate to be larger .... even if it is cloudy, but also make the motor have enough current to stabilize the work.
Q:How does the solar self-priming pump be installed?
Installation to minimize the hydraulic loss of the suction pipe, not less than 90 ° elbow, 90 ° elbow on the import pipeline should not be more than 2, the pump inlet should be set to filter, to prevent large impurities into the pump , To ensure the normal operation of the pump, the installation as much as possible to reduce the import pipeline long way (this will reduce the import pipeline air, thereby reducing the self-absorption time, increase efficiency).
Q:What is the pump for solar hot water
Traditional solar water heaters are falling into the water. The water pressure depends on the distance from the roof to the room, the greater the distance, the greater the water pressure. If the water pressure requirements, there are two ways
Q:Solar water heater automatic pressurized water pump does not turn how maintenance
The pump directly connected to the power to try (if the pressure switch, bypass the pressure switch to), see turn it. If the turn is to control the instrument or pressure switch problem.
Q:Solar water heater before the booster pump is now changed into tap water how to get
If your water pressure is sufficient, you can directly on the water pipe connected to the water pipe on the line.
