SunCentric The SunCentricTM uses solar-electric power
to pump as much as 50,000 gallons (200 cu. m.) per day from
shallow water sources. Applications include irrigation, livestock,
domestic water, pond management, water treatment,
solar water heating, hydronic space heating, fire protection, and
more. These pumps have been in worldwide use
since 1989. They can be used without batteries. Maximum suction
lift is 10 vertical feet (3 m).
 | PV Array-Direct Application
| A PV-direct system uses water storage instead of
batteries. This is the simplest and most durable system for
most applications. |
| A pump controller (linear current booster) is not
required. |
| A solar tracker (optional) will help to maintain optimum
flow through the entire solar day. |
| Storage of 3-7 days’ water demand is recommended. |
| Optimum for circulation of solar-heated water.
|
|
| Selecting a Pump
| Select the appropriate chart of "PV Array-Direct
Applications" or "Battery Applications". |
| Total Dynamic Head = Vertical distance from surface of the
water source to the discharge or top of storage tank + pipe
friction losses. |
| Use the solid line grid for English units. Use broken line
grid for metric units. |
| Locate the coordinates for the required head and flow.
|
| Find the pump curve that is nearest to that point. |
| If there is more than one curve to chose from, compare the
power requirements. If PV-direct, the curve that goes higher
will work better during low sun intensity. |
| For PV-Direct systems, array size (watts) is critical.
Do not undersize the array. Oversizing will improve
performance in low sunlight conditions. |
| Multiple pumps can be used to provide greater flow.
|
|
| Suction Capacity
| Suction limit is 10 vertical feet (3 m) at sea
level-subtract 1 foot for every 1000 ft. elevation (1 m per
km). |
| For best reliability, minimize or eliminate suction lift
by placing the pump low and close to the water source. This
will minimize the possibility of cavitation which causes
excessive wear and loss of performance |
