What is an open centrifugal pump?

Centrifugal water pumps use centrifugal force to pressurize and move water from the inlet to the outlet. A rotating set of vanes (called an 'impeller') is spun by the pump shaft. As water is forced through the impeller, rotational energy is transferred from the impeller to the water, which gains velocity and pressure through the centrifugal force applied and is flung from the impeller. The volute (a spiral-shaped case) funnels the now-pressurized water to the outlet. Image below shows clockwise rotation as viewed from the motor mound.Ningbo Guanghan Solar Pump Industry is a factory specialized in manufacturing solar submersible pumps and solar surface pumps. The head office was established in 1989 in Daxi Town, Wenling City, the hometown of water pumps in China, and a branch factory was established in Jiangshan Town, Ningbo City in 2019. It is located near the highway intersection, very close to Ningbo Port and Shanghai Port, and the transportation is very convenient.

What is the permanent magnet synchronous motor

A permanent magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. The stator carries windings connected to an AC supply to produce a rotating magnetic field. At synchronous speed the rotor poles lock to the rotating magnetic field. Permanent magnet synchronous motors are similar to brushless DC motors.Because of the constant magnetic field in the rotor these cannot use induction windings for starting. These motors require a variable-frequency power source to start.The main difference between a permanent magnet synchronous motor and an asynchronous motor is the rotor. Some studies seem to indicate that NdFeB permanent magnet synchronous motors are around 2 percent more efficient than the highest-efficiency (IE3) asynchronous motors—using the same stator laminations and similar variable-frequency speed controllers.Permanent magnet motors have been used as gearless elevator motors since 2000.Ningbo Guanghan Solar Pump Industry is a factory specialized in manufacturing solar submersible pumps and solar surface pumps.

How about your capacity?

We can produce 400-500pcs dc solar water pumps a day, which can be a good guarantee that we will deliver within the stipulated time.

Which is better--a DC or an AC pump?

The DC pump can directly use the DC power generated by the solar panel to run the water pump. Reduce the power loss in the conversion process. Therefore, the DC pump is more efficient and requires fewer solar panels. The DC pump also does not require an inverter to convert the direct current generated by the solar panel into alternating current. Reduced costs. 

Can the speed of the solar water pump be adjusted?

Yes, the controllers come standard with a speed adjustment dial whereby you can reduce the speed of the motor if needed.

What is the difference between TPS, TPPC, TPSC series?

TPS series are solar screw pumps. The characteristic of screw pump is high head and small flow. Suitable for domestic water supply.TPPC series are solar-powered plastic impeller solar deep well pumps. It is cost-effective, has a long service life, is more durable than a screw pump, and has a larger flow rate. However, the head is relatively small.TPSC series are solar submersible pumps with stainless steel impeller. Stainless steel impellers are more durable than plastic impellers, especially in waters with high sand content.

How Is Your Packing Method For Solar Pumps Kits?

Our solar powered water pumps and controllers will be wrapped in bubble bags, and then put them in the wooden box together with the accessory bag. Our wooden box is shock-resistant and anti-drop.

Do you have any requirements for small solar powered water pump OEM service?

We provide OEM service for customers free of charge. You only need to order more than 10pcs small solar powered water pump and we can provide OEM service for you. We will laser your exclusive brand on the motor and controller of the pump, but for wooden boxes, you can only use our conventional wooden boxes. If you order more than 200pcs solar water pumps, we will customize your exclusive wooden box for you, and we will print your exclusive brand logo on the wooden box.

What are the free accessories of TPON solar solar well pump system?

TPON brushless solar water pump kit includes 1pcs solar pump, 1pcs solar water pump controller and some free installation parts. Free accessories includes : insulation tape, teflon tape, heat-shrinkable tube, screwdriver, screw and nut, connection terminal.

Do I need to use an inverter?

No need, our MPPT controller has a frequency conversion function to directly convert solar energy into energy for water pump work.

Are your solar pumps easy to install?

After you received the pump, we will send you the installation drawing and video.

How long is your solar powered pump lifetime?

Pump lifetime mainly depends on motor lifetime, we have DC brush, brushless, coreless brushless motor For your choice, the pump and controller warranty is 1 year.

How does your factory conduct quality control?

Quality is very important and always be put in the first place. We insist one worker charge one process. Having our own Aluminum Die-casting Workshop and Plastic Injection Molding Workshop allow us easier to control the quality. Inspections of each step will be done during the production process.

How to choose suitable solar water pump?

Firstly we should know from you :What is the fluid? Clean water(temperature), dirty water(temperature), particles,or slurry ? What is the flow and head? And the power?Other conditions from customer if possible: pump type, motor? With complete information, then we selected the pump and feedback to you.
