Lorentz Submersible Solar Pumps
Small solar powered water pumps are ideal for boreholes, wells, livestock, transfer or irrigation pumping.
Larger scale village or communal water supplies are also possible using higher voltage systems, which retain the efficiency advantages of DC motors, whilst keeping cabling costs to a minimum.
German engineering company, Lorentz Gmbh, has been involved in the solar pumping industry for many years. They have a worldwide reputation for designing and building highly efficient and reliable DC powered water pumps.
Most of the Lorentz pumps will run direct from a solar pv array, via the supplied pump controller. All pumps are capable of running from a battery bank.
The pump controllers feature dry run protection and low voltage disconnection, as well as LED displays showing the status of the system.
Lorentz pumps feature highly efficient brushless 3 phase motors, which run 'wet' and so there are no rubber motor seals to fail. Extremely robust stainless steel components and experienced design ensures many years of reliable service.
With extremely low running costs, these pumping systems are designed to last for many years with minimal maintenance. Lorentz pumping systems come with a two year manufacturers warranty.
Pump head temperature class (-X):
class 0: 0 to 10°C (+2°C)
class 1: 10 to 20°C (-2°C, + 2°C)
class 2: 20 to 30°C (-2°C, + 2°C)
class 3: 30 to 40°C (-2°C, + 2°C)
class 4: 40 to 50°C (-2°C, + 2°C)
For PS200 HR Pump Systems the Pump Units / Ends, one class higher is used, for example with the PS200 HR-04-2 Pump Units / Ends PU HR-04-3, PE HR-04-3 are used.
Exceeding temperatures by more than 5°C may cause the pump to stop. Operating temperatures below the temperature class may result in significant reduction of flow rates.
