Lorentz solar powered stock watering systems
 It’s
never too early to start planning your spring or summer stock
watering system and the Lorentz line of super efficient
solar-powered pumps can help you get it done cost effectively. From
their surface mounted centrifugals to submersible helical rotor
pumps, Lorentz has a pumping solution that will fit almost every
need and budget. For shallow well applications (less than 70’ deep)
their amazing PS150-Centric submersible centrifugal pump can deliver
high volumes of water with a small solar array. For deeper
applications, the Lorentz PS200/600/1200 submersible helical rotor
pumps can provide lower volumes of water from depths up to 760’.
These helical rotor (or progressive cavity) pumps are positive
displacement units which means that they will pump some water even
in low light level conditions. They have brushless motors, but no
problematic diaphragms so they don’t require any regular
maintenance; that means that you can just set it and forget it. This
will save you a lot of time, money and maintenance over the life of
the pumping system. If something should go wrong, all of the
electronics for the Lorentz submersible pumps are located in the
above-ground control box which makes trouble-shooting and
repair/replacement a lot easier than having to pull the pump. All of
the Lorentz submersible pumps and controllers are covered by a
2-year manufacturer’s warranty against defects in material and
workmanship except the PS150 Boost pumps which have a 1 year
warranty. Please look over these Lorentz sample submersible pumping
system below and let us know if any of them will meet your needs. If
not, give us a call with the details on your particular pumping
situation and we will design a system just for you.
Lorentz PS150 submersible centrifugal (shallow
well, high volume)
1 Evergreen Spruce ES-190-RL 18V 190W solar module
1 single module top-of-pole mount structure (2” ID SCH40
steel pipe required)
1 15’ array-to-controller wiring kit
1 Lorentz PS150 pump controller
1 Lorentz CSJ5-8 submersible centrifugal pump
1 Lorentz low water sensor
1 float switch
Equipment total = Please call for pricing.
On average this system will produce ~2,100 gpd when pushing against
50’ of head with 5 hours of full sun per day.
Lorentz PS1200 submersible helical rotor (deep well, low volume)
4 Evergreen Spruce ES-190-RL 18V 190W solar modules
1 four module top-of-pole mount structure (4” ID SCH40 steel
pipe required)
1 15’ array-to-controller wiring kit
1 Lorentz PV disconnect & junction box
1 Lorentz PS1200 pump controller
1 Lorentz HR-03H-2 submersible helical rotor pump
1 Lorentz low water sensor
1 float switch
Equipment total = Please call for pricing.
On average this system will produce ~600 gpd when pushing against
760’ of head with 5 hours of full sun per day.
Note: the PS600 & PS1200 systems can be powered by a 120/240 VAC
generator or utility power during cloudy periods by using the
Lorentz AC power pack.
Here’s the chart that shows the cost versus
performance of four more Lorentz pumping systems; let us know if any
of them will meet your needs. All systems come with detailed wiring
diagrams.

minimum of 5 full sun hours per day and are averages (i.e. your

Visit
www.pvsolarpumps.com/water_pumping_questionnaire.html and
answer the questions so
we can quote a system specific to your project needs….we basically
need the following information:
-
What is the watering application? Domestic use,
stock, irrigation, etc.?
-
How many full-time residents, or how many head
of stock (and what type of livestock) will be needing the water?
-
Where is this system going to be located (city,
state, country or latitude & longitude)?
-
What is your water source (well, pond/lake,
spring, stream)?
-
What is its production rate?
-
If your source is a well, we need to know
interior casing size, depth of the well, static water level from
the ground, and what is the drawdown level from the ground?
-
Will this system need to push water to a tank or
cistern located above your water source? If yes, what is the
linear distance as well as the elevation difference between the
water source and the storage tank? Also, what is the storage
capacity of this tank or cistern?
-
Is there at present a pipe installed connecting
the water source to your tank or cistern? If yes, what size is
the pipe ID and what type (steel or PVC) is it?
-
Will this pumping system be used year round or
seasonally?
-
We need to know your daily volume of water
needed during each month of the year that the system will be in
use.
-
Is there already a pump installed at this
location? If so, we need to know what sort of pump it is
(manufacturer, model number, AC or DC, operating voltage &
amperage, years installed, etc.)
-
Any other details regarding your existing system
or site that you feel may be helpful in our system design
process.
