The main feature of the Submersible Well Pump: the suction inlet is at the bottom of the pump, the electric motor is at the top of the pump as driving device. The liquid enters the column pipe through the motor external water jacket and cools the motor at the same time. There shall be a series of advantages, such as compact structure, corrosion resistant, less land occupation, noiseless and easy to realize auto control, and especially suitable for shallow water working conditions. Choosing different material, it can be also applied in water works, power station, steelworks, agricultural drainage and irrigation, fire water, municipal construction and so on.

If you prefer getting water from a well, reservoir, or other such sources, you may want to buy a submersible well pump. With a good submersible pump, you can now access water from as deep as 400 feet. Apart from being energy-efficient, these pumps are submerged in water, eliminating the need for manual priming that takes a lot of time. You will also benefit from their quiet nature. In contrast, most surface mounted pumps tend to make a lot of noise.
Submersible pumps will vary depending on construction, durability, performance, and features. Our engineer will save you the trouble of having to go through all the options available and help you narrow down your choice to the most suitable pump for your unique needs.

The Grundfos comes with an inbuilt control box, so there are no extra costs that come with this buy. It is also easy to operate and install.
You will love its soft start technology that makes the motor both generator and inverter friendly while preventing water hammering and electrical disturbances. Additionally, the soft-start motor will serve you longer and last for many cycles. With its high starting torque, you can enjoy a reliable supply of water even at low supply voltage. And you get an automatic restart feature.
It comes with a stainless steel body and a built-in check valve made of stainless steel that guarantees protection from external damage. It also won’t rust easily. If you make this buy, you will be getting a discharge rate of 33 GPM, making it ideal for deep wells. But it can also work in reservoirs, rivers, and canals.
This means that you can count on this pump to supply your house or irrigate your farm without hitches. But there is a catch. Although it comes with a double cooling system to prevent overheating when in use, you cannot exceed its maximum heat tolerance of 40 degrees Celsius.
Let’s use an example to illustrate proper pump selection. Let’s say that you have a well that is 400’ deep with a static water level (water level in the well when the pump is turned off) that is at 200’ below ground. The water level in the well drops to 300’ below the surface of the ground when the well is pumped at 15 Gallons per minute. This water well supplies water to a house that is on a hill that is 50’ above the well and the house needs to have 50 PSI (115’) of pressure available at the house. The house has minimal landscaping and 15 GPM is more than adequate to meet household demands. The pipes supplying the house have friction loss values of 35’ TDH at a flow rates of 15 GPM.
The total dynamic head (TDH) is calculated twice, once for the best case scenario with a high water level in the well and again with the worst case scenario, with a low water table in the well:
Best Case Design Point= 200’+50’+115’+35’=400’ TDH @ ~15 GPM with well not recently in use
Worst Case Design Point=400’+50’+115’+35’=600’ TDH @ ~15 GPM with well in use for a period of time
QJ series pump is multistage centrifugal pump,which consists of pump shaft, impeller, casing, bush, wear ring and other parts etc. According to different working conditions , pump parts separately select relevant material. When using in clean water, the main material is normally cast iron and carbon steel. When using in seawater or similar corrosive liquid, the main material is normally Cu-Ni alloy or stainless steel. In order to extend the life cycle and raise the quality of pump, excepting for choosing the superior materials and precisely fabricating on products, we continuously improve on structure of products and process of technology.
The motor matched with above pump is PY(H) series electric water (seawater) submersible 3-phase asynchronous motors, which is of wholly sealed construction full of clean water. Stator windings are wound with polyethylene insulation nylon covered winding. According to different working conditions, the external surfaces of motor are all made of relevant corrosion-resistant metal. Motor adopts mechanical seal or oil seal for moving seal. Motor bearings are of self-lubrication, and are lubricated by clean water or coolant. Motor cable is corrosion-resistant and water-resistant flat or round cable with guard sleeve.
