LORENTZ PS2 Solar Pump

PS2 is an advanced solar water pumping system. The system is designed specifically to use the power of the sun to move water, so replacing the need for grid power or diesel. As solar power is not consistent through the day, the PS2 constantly changes the pump parameters to optimise the amount of water supplied.

PS2 Solar Water Pump

The Lorentz PS2 Solar Pump is an integrated solar water pumping system that is perfect for small to medium sized applications and may be suitable for larger scale applications.

PS2 provides a very efficient total solution to meet your solar water pumping needs with the following benefits:

  • Reduced operational expenses with zero energy costs.
  • Improved water security.
  • Improved sustainability reducing reliance on diesel or electricity for power

Applications of PS2 Pumps

Solar water pumping systems are most commonly used in agriculture for irrigation or watering livestock. LORENTZ solar pool pumps are also used in residential and commercial pools across Australia.

Irrigation Solar Pumps


Drip, flood or pivot irrigation for crops on farms with zero energy costs.

Livestock Solar Pumps

Drinking Water

provide drinking water for livestock and communities.

Solar Pool Pumps

Pool Pumps

Residential or Commercial Swimming Pools.

The Complete Solution

The solar water pump itself as part of a wider system which is highlighted below. To understand which complete solution is best for your farm or station, you are best to speak to one of our expert dealer partners across Australia and New Zealand as they can help calculate the exact system that you need, based on your location, geography and water requirements.

However it is beneficial to know the components of complete system which contains the PS2. This includes the following:


The controller is at the heart of the system, managing both system operations, analysing inputs and constantly optimizing the system for maximum water output.

Power source (solar panels)

Solar power is the PS2’s power source. In almost all cases the water requirements can be met with a well-designed solar system and water storage.

Monitoring and management

All PS2 systems have inbuilt data logging and a simple management interface. All systems can be remotely monitored and managed via our LORENTZ Global solution.

This means no more traveling to pumps to fill them up with diesel or petrol, you can simply manage the water levels and requirements and adjust as required all from a mobile phone or computer interface.


Solar Pump

LORENTZ PS2 has a wide range of submersible and surface solar pumps to meet your specific water needs. The largest LORENTZ submersible pumps can pump water that is 450 metres deep, Surface pumps can achieve flows of up to sixty cubic metres per hour.

Distribution Network

Whatever the PS2 pump is connected to, the system will optimise water delivery depending on the power available and inputs from the various sensors.

Water Storage

Introducing water storage to a solar water pumping system allows for increased seasonal demands to be met, or simply for overnight water availability without a generator or grid power.

Benefits of a LORENTZ PS2 Solar Pump

No infrastructure to install

Using solar power means that you can install a pumping system almost anywhere, irrespective of power infrastructure availability and the associated costs. Our PS2 series is designed for the harshest off-grid environments.

Low operational costs

Operational cost savings are achieved as the system requires no or reduced fossil fuels, can be fully remotely managed and is designed to have a long working life. The result is very low costs.

Right sizing

Ps2 uses brushless and sensorless DC motors for maximum efficiency. This results in significantly more water being pumped with the available power. This efficiency results in a lower unit cost of water. 

Lowest project risk

As PS2 is designed to be a complete system, it has all of the needed software and hardware for your water project. The result is that your projects are delivered on time, on budget and without technical risk.

Increased serviceability from PS2 solar pumps

PS2 is designed to be field serviceable. The pump unit components and electronics are modular to allow for cost effective and fast replacement.

Efficiency at its best

The efficiency of PS2 means that the system starts earlier in the day, pumps more during the day and stops later. This can make a significant difference to the people, crops or animals that use the water.

LORENTZ has conducted tests against our leading competitors and have found that our systems are up to 1,460% MORE efficient!

Consider the full picture before you invest

When you compare systems look at the water that is pumped for your investment. Comparing motor sizes, solar panel sizes or theoretical maximums are not good indicators of how much water you will be able to pump.

When making your comparisons look at the whole system costs. Adding extra solar modules, racking cabling and labor to get competitors’ products to meet LORENTZ performance gets expensive.

Speak to your local LORENTZ dealer to assist with system sizing and pricing. Our dealers across Australia and New Zealand are trained to us COMPASS – the LORENTZ system planning software – will accurately simulate real world situations and design a system that will give you the water you need, when you need it.

PS2 Products

An effective solar water pumping system is made up of more than one component. When you choose a LORENTZ system you will get an integrated solution design specifically for solar water pumping from a company with absolute focus on this technology.

PS2 Controller

PS2 controllers are available from 150 W to 4 kW. The controller includes the electronic to drive the ECDRIVE brushless DC motor, software for our water applications, all the inputs you will ever need, data logging, plus intelligent control over the whole system to give you the most water possible.

PS2 Submersible Pumps

PS2 4” helical rotor pumps and 4” to 6” submersible multistage pump means that your hydraulic needs can be closely matched for maximum efficiency. All LORENTZ pumps are preconfigured in our PumpScanner App with a simple 3-click setup.

PS2 Surface Pumps

PS2 single or multistage surface pumps perform equally well in irrigation projects and for drinking water applications where they reliably meet the most demanding requirements. All LORENTZ pumps are preconfigured in our PumpScanner App for simple 3-click setup of any system.

PS2 Pool Pumps

Two sizes of pool pump system are offered on PS2. These two systems meet the requirements of most residential and small commercial pools. Due to the efficiency of the PS2 system a smaller motor size is required to keep the pool clean.


To complete your PS2 system LORENTZ provide a wide range of compatible probes, sensors, solar power connection equipment, racking and PV modules. This enables a single source of tested, ready to integrate components to give you a complete solution.
