7.5KW 380V Deep well Solar Submersible Pump with Brushless high-speed Motor for fountain, irrigation, garden
Part 1. Intrduction of the solar pumping system
Solar pumping system is drived by solar power, the solar power is one of the most clean power in the world. Since the advanced design, the cost is lower, and take less time to keep maintenance. Mars Rock has experienced engineers to provide the suitable plan and good service after sale.
Part 2. Main Features
1. Brushless motor with high speed DC high performance, max efficiency can be 85%
2. Smaller size and less weight than other solar pumps, can be just 1/5 of them
3. Completed protection functions of the pump, stainless production of the impeller to assure the long time service.
4. Two working models, one model is just using the solar, one model can use not only the solar but also the AC power as complement.
5. Automatic switchover from solar to AC power, no need workers to serve all the time.
Part 3. Tech Parameters:
SZW series pump can both be powered by AC and DC. If the controller is connected with solar panels, then the pump is exactly a solar pump. Note: The pump power in the chart is in fact the output power. However when refer to the power of solar pump, we usually refer to its input power. If we want the high-pressure pump to work in solar mode, we have to work out its input power (its electric power). If the pump is powered by AC, the head, flow, power in the chart are all the related value.
2SSW, 3SSW, 4SSW are low-pressure pumps especially for solar use. If need pump with bigger power, we should use 2SZW, 3SZW, 4SZW, 6SZW pumps which is for AC and DC dual-use.
There is mini-integrated controller with the pump body together, we add T at the end of the model name. With this mini-integrated controller, the pump structure is very simple, and pump operation is very easy, those pumps only can pump water simply, just for those simple applications which no requires for water pressure, flow, peed etc.
The controller for this pump use the latest DC inverter technology, have all kinds of functions, such as: Soft start, constant pressure for water supply, also have the function especially for fountain, such as: Simulation control, bus-mastering.
The advantage of this pump with small size and light weight can be very obvious in water project, since this can greatly save the cost for installation and maintenance especially for those situations which require move or reinstallation frequently.
Part 4. Operation Model Description
Model One: Built-in micro computer control the on and off, when the sunshine is strong enough, systen turn on automatically; When solar is lack, turn off automatically, no people maintenance needed. DC inverter technology to control the speed, converter the frequency according to the solar power.
Model Two: Using the solar when the sun is strong enough, using the AC grid as complement; Using the AC grid when there is no sun. Solar and AC grid switch automatically, no need manual work.
