What is a SAMKING Premier
Solar Submersible Well Pump
(0.3HP–3HP)?
A SAMKING Premier Solar Submersible Well Pump is an advanced, Solar water pumping system designed to deliver dependable performance using only solar energy. Powered by a high-efficiency BLDC motor and controlled through smart solar technology, it draws water directly from deep wells, boreholes, ponds, or tanks — without relying on grid electricity or fuel.
Available in 0.3HP to 3HP models, these pumps combine high lift, strong water flow, and intelligent control to provide a sustainable and cost-effective water solution for homes, farms, and remote areas. Engineered for durability, low maintenance, and energy efficiency, SAMKING Premier Pumps ensure reliable water access — wherever it’s needed most.
These pumps are ideal for:
+ Domestic water supply in homes and communities.
+ Agricultural irrigation for crops, greenhouses, and farms.
+ Livestock drinking water systems in rural areas.
+ Deep wells and boreholes for continuous water extraction.
Each SAMKING pump is designed with efficiency, reliability,
and low maintenance at its core.

Characteristics of internal controller
solar pumps 0.3Hp-3Hp
+ Simpler installation
Because there is no separate control box to install and
wire, pumps with internal controllers offer a simpler installation process with a single power wire.
+ Lower upfront cost
Pumps with internal controllers are often less expensive
to purchase initially because they do not require the additional control box hardware.
+ Complex maintenance
When the controller fails, a technician must pull the
entire pump out of the well to service or replace it. This is a more complex and costly procedure.
+ Vulnerability to heat
The internal controller's electronics are submerged with
the motor. While water cools them, the components still run hotter than those controlled externally.

/ Quick Guide
Components of Solar
Motor Pumps
+ Sunlight falls on solar PV panels
Photons present in the sunlight displace electrons present in the solar cells that solar panels are made of. This flow of electrons produces an electric current in the form of DC power.
+ Solar electricity makes the water pump (optional)
The DC electricity is sent to a controller (and an inverter if needed), which powers the motor. For DC motors, the power flows directly. For AC motors, a solar inverter converts the DC to AC.
+ The solar pump starts drawing water
The motor drives a pump (surface or submersible) that extracts water from a source such as a well, river, or tank reservoir.
+ Extracted water is delivered to the end destination
The water drawn by the solar pump is transported through pipes to its end destination, which could be irrigating vast crop fields, supplying drinking water to homes, and delivering water for livestock watering.
