LORENTZ design and manufacture solar powered water pumping solutions

LORENTZ was founded in Germany in 1993. Since this time we have continually innovated and excelled in engineering solar pumping systems. Our focus on this technology area has developed into three complementary fields of expertise:

  • high efficiency, high reliability pumps
  • brushless and sensorless drives for high efficiency and long life
  • optimized solar capture where we track the sun to achieve higher and extended PV output

Today we continue to have our headquarters and design functions in Germany while manufacturing in our own facilities across the world. This unique mix gives us the most reliable sourcing of key components and best value manufacturing, something that guarantees quality at a very competitive price point.

We are LORENTZ, this is what we do and why we are proud of it.

Access to a clean, reliable water supply is critical for the survival of humans and animals. Ground water sources offer a cleaner and reliable supply of drinking water.

With a focus on reliability and efficiency LORENTZ has perfected unique designs for pumps, DC drives and controllers. Components are designed and manufactured using the highest quality materials to ensure a long and trouble free life with low maintenance requirements and low operating costs. LORENTZ pumps are matched to local water conditions for optimum performance. Intelligent designs keep electronics above ground and the brushless DC drives match solar generators perfectly.

LORENTZ solar pumping products deliver drinking water to people and livestock economically and reliably.

The need to irrigate agricultural land efficiently, eco-nomically and sustainably is critical for food security. Costs for irrigation using diesel power are rising at >10 % per year.

LORENTZ solar irrigation solutions produce no emissions, generate no noise. Solar power for irrigation is more reliable than wind power while being significantly cheaper and cleaner than diesel power. LORENTZ solar pumps complement the design of drip irrigation systems, delivering water precisely and efficiently to individual plants. Very high volumes of water for large scale irrigation can also be supported through a wide range of pump sizes and vertical lifts.

LORENTZ solar irrigation solutions are a very attractive alternative to diesel powered pumping and support sustainable agriculture.

For homes with swimming pools, circulation and filtration pumps used to keep pools clean are typically the second biggest consumers of electricity.

Using the technology, expertise and experience gained in critical drinking water applications, LORENTZ has a range of pool pumps that use zero electricity and have a long life. Additional benefits come from quiet operation and modular construction for simple maintenance. LORENTZ solutions save the homeowner money and reduce their environmental footprint. Tax benefits and government grants also encourage homeowners to make the change to solar pumping.

LORENTZ pool pumps are a compelling proposition for homeowners and commercial pool operators in a sector where operating costs need to be minimized.

Solar power is important to meet targets for renewable energy, to reduce CO2 emissions and bring electricity to developing communities.

LORENTZ solar tracking systems offer very attractive alternatives to fixed PV module installation both in terms of power generated and length of time power is generated. Tracking the sun reduces the physical size of PV panel area required for a given output, improving power yield and improving return on investment. Tracking combined with a solar pumping system extends the time that peak water yield can be achieved.

LORENTZ tracking solutions increase solar power yields and extend the performance of solar pumping systems.

PS Communicator and pumpMANAGER

Remote Communication Device and Cloud Management Service

The LORENTZ PS Communicator and pumpMANAGER service combine to offer customers a cost effective full management and monitoring system for their LORENTZ pump estate. This is attractive to commercial farms, industrial processes, government or NGO monitoring and anywhere that water is critical to people, livestock or crops.

The PS Communicator sends data from each pump across the cellular (mobile) data network to a secure central web server application called pumpMANAGER. The pumpMANAGER application can be accessed from any web connected device anywhere in the world making access to information and control of your solar pumps simple and convenient. As the connection is two way the pumps can be programmed, speed controlled or switched off, providing full remote control.

The pumpMANAGER application also monitors the status of your LORENTZ pumps systems and will alert you if there are any unexpected events.
