The
TSP-1000 has been accepted by several international aid programs, with
more than 1500 in use. Its superior efficiency results in far lower
system costs than competing solar submersibles.
TSP 1000 is the most powerful positive displacement submersible pump on the market. It is more energy-efficient than any centrifugal impeller submersible, and does not lose its lift capacity at slow speeds. This pump combines the time-tested, positive displacement helical rotor with new electronic motor technology.
 | Lift to 230 feet (70 m)
| Volume to 25 gpm (95 lpm)
| Fits into a 4" well casing
| Uses a 300-600 watt solar array
| Helical rotor pump for superior efficiency
| Brushless electronic motor
| Tolerates most silt and mineral conditions. | |
The helical rotor mechanism has but one moving part, a hard chrome-plated rotor that revolves inside of a rubber stator. The contacting surfaces form sealed cavities which progress upward as the pump turns. There is little friction, and virtually no back leakage. This type of pump, rod-driven from above-ground, has been proven for decades and is commonly used in Africa. TSP 1000 is the first successful submersible helical rotor pump.
The Motor & Controller
TSP 1000 uses a DC brushless high-torque motor specially built by a
leading European submersible motor manufacturer. The electronic
controller is located at the surface. The controller starts and runs the
pump in low light conditions and yields the most possible water from
varying sun conditions. The controller has connections for level sensor
probes to protect the pump from dry run damage. It also has connections
for a remote float switch to prevent tank overflow. The controller
displays the following data:
| on/off
| relative rotational speed
| overload condition
| low water level
| full tank level | |
The System
TSP 1000 can be operated directly from a solar array of 6, 7 or 8
photovoltaic (PV) modules in series. This gives the customer a choice of
pumping rates. Water storage sufficient for 4 to 8 days' usage is
recommended.
Installation
Pump installation is identical to that of a conventional AC submersible
pump, using either rigid or flexible drop pipe. Installation of the
solar array involves simple nuts-and-bolts assembly. The controller and
junction box included are fully weather proof and well-designed to make
wiring easy the first time.
