You might wonder why LORENTZ made certain choices when designing the LORENTZ S1-200. We have been designing and manufacturing solar pumps for 30 years. Solar pumps need to be designed differently to other electric pumps, they must operate with varying power conditions and are usually installed in hot, wet, dusty, sunny, exposed, sometimes cold places, and off grid. Here are some questions that we get asked.

Why use DC brushless (BLDC) motors?
Solar power varies through the day. The 8 pole brushless motor that is used in LORENTZ S1-200 pumps is super efficient, irrespective of power or speed. The result is 2-3 times more water than competitor products for a given input power. The motor design is internally water lubricated, has long life bearings, no brushes to wear or sensors to fail, all to maximize reliability and lifetime.

Why polymer and not stainless steel?
We use high quality engineering polymers in LORENTZ S1-200 pumps for parts that need to be accurate, durable and light weight. There are several benefits of polymer over steel, polymers can be injection molded with high accuracy without the need for secondary machining. Molded polymers fit well with high volume manufacturing and also reduce the weight of the product making it easy to move from source to source.

Why submersible pumps and not surface pumps?
We chose a submersible design for flexibility and for use in the widest range of applications. Submersible pumps have some benefits over surface pumps that make them much easier to use. The LORENTZ S1-200 can be used in a river, stream, pond, tank, dam, well or borehole. There is no need to prime the pump, just drop it in the water. There is no need to consider “suction limits” with a submersible pump. There is also no need for a suction hose and a discharge hose, just one pipe. The submersible pump is small and light weight allowing it to be easily transported.

Why a Helical Rotor (HR) pump?
Helical Rotor / progressive cavity pumps are used across many industries and are known for their efficiency and reliability. Helical Rotor pumps will create pressure at any speed which means that as soon as the pump motor can turn water will pump. The LORENTZ S1-200 pump mechanism is very efficient and reliable.

Why pre-plugged?
One of the biggest barriers to installing solar pumps is wiring. The LORENTZ S1-200 is “plug and play”, all wiring is done using weatherproof plugs. The plugs are unique so there is no risk of wrong connections.

Why have an app?
You don’t need to use the LORENTZ S-Connect app with LORENTZ S1-200 but it opens up some extra features and functions. You can for example set timers of when you want the pump to run, set a daily water amount, configure sensors or just see performance data. The LORENTZ S1-200 app also assists with troubleshooting.
