HD-SCPM21-16-72-750 HANDURO Solar Pump is a highly efficent solar water pumping system option. This model is targeted for agriculture, irrigation and off-grid water supply uses and designed to perform the functionally best with more heavy duty made capabilities on solar power inputs.
Brand Overview: HANDURO’s Reputation for Quality
Water pumping company handuro is a recognized name with long lasting, most efficient and very low maintenance Pumping system. As a result, the HD-SCPM21-16-72-750 shows that the entire brand is committed to innovative solar technology and environmentally friendly infrastructure.
Main Specifications of HD-SCPM21-16-72-750
Power Output and Efficiency
- Rated power of 750W (0.750)
The 750W power rating places the unit in the mid-range performance solar water pumping world, maintaining a reasonable equilibrium between output and energy efficiency. Its meant to be used on solar panels and works at optimal level with just the requirement of mere hardware, no configurability or oversizing needed.
Voltage Requirements - HD-SCPM21-16-72-750 HANDURO Solar Pump
Nominal voltage: 72V DC
- Recommended Operation Voltage: 90-120
To make use of this voltage range the pump can be run with maximum of Torque and efficiency, to take full input from Solar and least conversion losses. It is also well-suited for use with standard, off-the-shelf solar PV arrays (3x 24v panels in series) which simplifies installation and lowers expense.
Flow Rate and Water Delivery Performance
Maximum Flow Rate:
- Q.Max: 21 m³/h (cubic meters per hour)
It has a high rate of flow, beneficial for applications that call for fast-moving water, such as large-area watering, watering of stock, and public water supply. In its maximum capacity, it can yield 21,000 liters of water in an hour, sustaining heavy operations without compromise.
Maximum Head (H.Max):
- H.Max: 16 meters
The 16 meters of head capacity the pump shows off means the higest vertical distance in which water can be pumped by it. This makes it suited for shallow well pumping, pond transfers and surface water transfer where the lift demands are not heavy but frequent.
Inlet and Outlet Dimensions
- Inlet/Outlet Size: 2 inches
Ports of 2-inches are typical for midsize solar water pumps and thus may be compatible with normally used piping system. This provides a clear path of the dynamics of the flow and down resistance, therefore stable volume delivery.
Performance Curve Insight
Even with the performance chart image being a bit unclear, we can infer the overall trend that lies behind centrifugal solar pumps like HD-SCPM21-16-72-750 (image credit: typical).(Image:Left: free flowing design.)
- Higher flow rates at lower heads
- Reduced flow at maximum head capacity
For example:
| Head (m) | Estimated Flow (m³/h) |
| 4 | ~20.5 |
| 8 | ~18.0 |
| 12 | ~14.5 |
| 16 | ~10.0 |
This curve depicts the typical inverse nature of vertical lift and rate of flow. Below small lifts the pump is still pumping at its maximum rate of flow but as the height increases this drops —though not much and ample for a pump to run.
Construction and Material Strength
All HANDURO parts are made out of high grade stainless steel so sand, corrosion and minerals cannot affect them. Designed with the shaft and impeller inner systems for longer hours of operation / less wear impeller internal, so the pump can be long-distance, low maintenance applications. This makes the pump perfect for long haul unattended areas with just a margin maintenance interval.
Solar, compatibility and integration of controller
This pump is basically designed to work with a solar pump inverter/controller which in effect performs the following functions for this pump to function according to its design specifications is as follows;
Regulates voltage and current in
- MPP (Max Power Point) Tracking: Offers: real-time solar optimization with MPPT
It has dry run protection, overload protection and system diagnostics
An ideal controller causes the pump to learn how much sun may come up, and at half sun status it is so efficient it will not shorten his life.
Ideal Use Cases
- Irrigação Agr
Its high volume of 21 m³/h means it can service many ha per irrigation, either through the use of trickle or flood irrigation. The solar power of this system is also to terminate long term energy expenses and serve the water even in the most distant off grid rural regions.
Livestock Watering Systems 2
If pure and assured supply of water is going to be available to your stock and ranch operations. The pump delivers large low lift flow, flowing constantly troughs, tanks and reservoirs.
- Village and community WATSANS
Having a perfect flow & lift ratio, the HD-SCPM21-16-72-750 is capable to work with small rural areas pumping water from shallow well or surface source into centralized tanks for distribution.
- Aquaculture and Pond Control (Pond)
Fish farms and aquatic systems will require water flow, oxygenation, or treatment constantly carried on such as the case of this pump for capacity and independence in flow of energy.
Installation Considerations
- Mount solar panels facing due south (in the northern hemisphere) for maximum exposure
- Use oversized cable gauges to reduce voltage drop over long distances
- Install a protective screen or filter at the inlet to avoid debris entry
- Ensure the pump controller is housed in a weatherproof enclosure
Each HANDURO pump is designed for easy plug-and-play solar,so first-time installers can quickly implement a high performing pumping system that will work well for the long haul.
