"Solar Water Pump Solution in Drinking Water Supply!"
A solar power water pump provides a sustainable and efficient solution for domestic drinking water. It operates cost-effectively using free solar energy, eliminating fuel costs and ensuring operation even in power outages. Highly reliable with minimal maintenance, it offers energy independence, improves access to safe water, and reduces environmental impact, making it an ideal choice for off-grid homes and environmentally conscious households.

Design a suitable Solar Water Pump System
3. Pump Operation
The pumps are mainly divided into two types:
Surface Pumps : Installed above ground, suitable for drawing water from sources such as ponds or shallow wells and delivering it to storage tanks.
Submersible Pumps : Immersed in water, typically located deep within wells or boreholes, designed to push water from deep aquifers to the surface.
A key feature of this system is that its pumping speed adjusts according to sunlight intensity. During peak sunlight hours (e.g., midday), pumping is fastest, while at night or on cloudy days, the speed slows or even stops. Therefore, the water storage tank becomes a critical component, ensuring a continuous water supply even during periods of insufficient sunlight.

Tips：How to calculate Lift/Head?
h1: Lift underwater (the vertical distance between the water pump and the water surface)
h2: Lift above water (the vertical distance between water surface and the wellhead)
h3: The horizontal distance between the well and the water tank
h4: Tank height
Actual lift required: H=h1/10+h2+h3/10+h4
Size Product example:
A Kenyan client informed us that he owns a deep well with a diameter of 120mm. The water level in the well is at a depth of h1=50m from the ground surface, the Water Tank height is h2=10m, and the distance between the Water Tank and the well is h3=40m. Their desired water consumption is Q=6m³/h, The customer expects the water pump to operate continuously at night, and they have a 220V AC power supply available to power the pump.
Based on the basic information provided by the client, we conducted the following analysis:
the client's rated head requirement is 50 + 10 + 40/10 = 64m, and the rated flow requirement is 6m³/h.
According to this information, we calculated and recommended the Z4PC9-125-300-2200-A/D model water pump. This pump has a diameter of 95mm and Pump Outlet 2 inches, with specific performance parameters as follows:
| Z4PC9-125-300-2200-ZSAD | Head(m) | 120.0 | 110.0 | 100.0 | 80.0 | 60.0 | 40.0 | 20.0 | 10.0 |
|---|---|---|---|---|---|---|---|---|---|
| Z4PC9-125-300-2200-ZSAD | Flow(m3/h) | 2.5 | 3.9 | 4.6 | 5.8 | 6.9 | 7.9 | 8.6 | 8.9 |
