Lorentz Solar Pool Pump with PS600 Controller

LORENTZ
BADU TOP 12
Solar Operated Centrifugal Surface Pump

BADU TOP 12 (SunCentric P) uses solar-electric power to pump water. It is cost-effective for swimming pools, especially where utility rates (or daytime peak rates) are very high. A pool pump is often one of the largest electrical loads in a home. A solar pump is practical because the need for filtration is greatest during sunny weather. It is perfect for pumping with photovoltaic modules because the circulation requirement corresponds with solar intensity.

Rules for energy-efficient pool pumping:

• The normal requirement of a pool pump is to pump the entire volume of the pool per day. Choose a pump that will not greatly exceed this daily volume on a sunny day.
• Choose the filter carefully. Its back pressure imposes the biggest load on the pump. A large filter will impede the flow less than a small one. Cartridge filters impose less resistance than sand filters. The filter maker's specifications will show the back pressure vs. flow rate. Two filters can be piped in parallel, to split the flow and cut the back pressure in half.
• Use large sized pipe to reduce friction. For a typical residential pool, this generally means 2" pipe instead of 1.5" pipe.
• Avoid sharp 90° elbows where possible. Instead, use long-radius elbows, 45° elbows, or flexible hose.
• Consult friction loss charts for pipe and fittings, then calculate the total pressure drop due to friction of all components.
• Choose a pump that uses the least power for the flow and pressure required.

Swimming pool application requirements
Piping Low friction is critical to performance. 2” is preferable. Avoid sharp 90° bends, especially in 1.5” pipe. Filter type There are three common types of filters: (1) CARTRIDGE filter is best. It works well at low and variable flow rates, and has low pressure-drop, (2) SAND filter works well at low and variable flow rates, but check the specifications for pump requirements for backwashing. The solar pump (by itself) may not produce sufficient backwash. (3) DIATOMACIOUS EARTH (DE) filter does not work well below a specific pressure, and may not function fully with a solar pump.

Automatic Pool Cleaners
This pump may not be adequate to operate a pool cleaner (pool sweep) that depends on the filter pump. If a conventional pool pump is not installed as a backup, a pool cleaner booster pump or a selfdriven cleaner can be used. This pump will not operate an in-floor cleaner with pop-up jets.

Retrofiting an existing pool system
In a retrofit situation you may not have the opportunity to follow all of the efficiency rules, but there is hope. If you feel that a reduced rate of flow is acceptable, then the power requirement will be reduced drastically! This easy example illustrates the principle-If the flow were to be reduced by 50%, then the back pressure imposed on the pump will be reduced to only 25%.

Theoretically, the power required to pump 1/2 the flow at 1/4 the pressure will be 1/8, or 12.5%! Using the same arithmetic, a more reasonable flow reduction of 25% would reduce pressure drop to 56% and the power requirement to 42%. If a pump is selected that is efficient at this reduced range, then the theoretical saving can be realized. If the pump is more efficient than the original pump, then the saving will be greater.

Supplemental methods of pool management Modern pool technology provides methods of pool cleaning using chemistry, electro-chemistry and robotic pool cleaners. These methods can be used to reduce the filtration pumping requirement, thus allowing the use of a lower rate of flow. Consult with an authority on pool sanitation to learn how these methods can reduce pumping requirements without compromising the safety of the pool.

Using a backup pump It is easy to install this pump parallel to an AC pump. The AC pump can serve as a backup or to supply additional flow on cleaning day. Connect the pump intakes together. Install a low-resistance check valve at each pump's outlet, then connect the check valve outlets together. Either pump (or both) can be turned on, with no need to touch any valves.

Long-term economy
Solar pumping is a long-term investment. Most photovoltaic solar modules have a 20 year warranty, and a life expectancy beyond 30 years. The Lorentz BADU TOP 12 pump can also last that long. It will far outlast a cheap AC pool pump because of its high industrial quality and lower rotational speed

Manufacturer’s warranty
