We supply the LORENTZ solar pumping
system. We see huge potential for the use of
solar-powered pumping systems. Solar powered pumps are
efficient, reliable, cheap to run, easy to install, and
require little or no maintenance. Unlike windmills,
solar pumps will pump the most water when you need the
most - those long hot dry still days that Australian
summers are famous for. There is a
large range of LORENTZ pumps suited to many different
pumping applications. The PS200, PS600 and PS1200 models
are full 316 stainless steel helical rotor pumps that
can suit bore or surface water applications to a maximum
head of 230 metres. The LORENTZ product range also
includes a range of solar-powered centrifugal pumps, and
the Badu-PS600, PS150-Boost and PS200-Air special
purpose pumps. All the models pump directly from solar panels
utilizing an electronic controller, so there is no need
for batteries, though battery charging can be added if
desired. A power-pack is also available so mains or
generator power can be used as a backup for high
water-demand periods. LORENTZ pumps are very competitively priced and
are usually supplied as a complete system kit with full instructions
so that they can be simply self-installed if required.

The LORENTZ solar pump was designed in
Germany by Bernt Lorentz and is the most
cost effective and reliable solar pumping system
available in Australia. With 20 pump models, 5
controller models, and 37 solar
panel combinations, we can provide exactly the right
solar pumping system for your application. If you have a
bore, river, creek, well, spring, tank or dam, we can
design the perfect LORENTZ solar
pumping system for your needs.
The PS Series of submersible pumps
eliminates the weakest links in solar pumping by using
helical rotor (progressing cavity) and centrifugal pump
ends and a brushless and water-filled motor. This means
that there are no failure-prone diaphragms or motor
bushes to replace.
All electronic control parts are
above ground for easy access and greatest reliability.
The controller is weather-sealed for all climates. The
LORENTZ system is supplied as a complete system kit,
engineered for the lift and daily volume that you
require.
 DEEP WELL
APPLICATIONS. The pump can be submerged as deep
as necessary to ensure reliable water supply. Submersion
depth does not affect the performance or place
additional stress on the pump or motor. It fits 4” and
larger bore casings.
SURFACE WATER
APPLICATIONS. The pump can be installed in a
stream, pond, tank, or well, in any position. This
eliminates any need for a pump house or for periodic
priming.
DRY RUN
PROTECTION. A low water probe turns the pump
off to prevent dry run damage. Reset is automatic after
20 minutes. The controllers have a RPM limit adjustment
to reduce the maximum flow rate to about 50% to help
match a limited water supply.
SAND AND SILT
TOLERANCE. The pump has high resistance to wear
from sand, clay etc that may occur in a properly
constructed well. However, a concentration of solids
greater than 2% (by volume) may cause blockage in the
pump or the drop pipe, particularly at low flow rates.
CONTROLLER. Low level probe, and float-/remote switch terminals.
Lights indicate: system on, pump on, pump speed, tank
full, water source low, overload, and high temperature.
WETTED
MATERIALS. 316 stainless steel, stainless steel
check valve, chromium. NBR rubber, natural rubber,
polyurethane (cable).
STORAGE
REQUIREMENT. A storage tank (not included)
should be sized to supply a minimum of 5-10 days water
supply, depending on climate and application. Water
storage is generally more economical than energy storage
in batteries.
SOLAR TRACKER
OPTION. A solar tracker automatically aims the
solar array at the sun throughout the day. In clear
weather, tracking increases the daily water volume by
about 40% in summer (15% in winter). The tracker’s drive
uses a simple linear motor.
NEED MORE
WATER. Consider the PS1200 system for
high heads. This system
uses more power to pump as high as 230m (750’). Or if it
is volume at low heads that you want, look at the PS1800
range of centrifugal pumps. And for smaller
applications, you can't go past the economy of the PS150
Centric, which can utilise as little as one 64 Watt
solar panel. But our most commonly required system is
the simple helical rotor pumps, coupled with a range of
controller models to suit your application.
INSTALLATION. Install the pump by the same methods and materials used
for conventional submersible pumps. The solar array
requires nuts-and-bolts assembly and standard wiring
practices. The instruction manual is clearly illustrated
and no special product training is required.
WARRANTY. 2 years manufacturers warranty against defects
in materials and workmanship.
Sample
installations

2
panels fixed
This is a PS200
system using 128 Watts
of solar panels. This system was
installed to equip an
old bore. At a 20m total
head, it pumps 3,800
litres per day. There is approx 2 km
of pipeline to the
storage tank.

3 panels
mounted on windmill
tower
In this situation, a
solar pump was installed
to replace an existing
windmill, utilizing the
windmill tower to mount
the solar panels. The
water in this bore is
very corrosive, meaning
galvanised piping had to
be continually replaced.
The solar pump is
utilizing polypipe. This
system is a PS200HR with
192 Watts of power, and
gives 4,600 litres a day
at a total head of 30m. |
 |
4 panels fixed
This was a new bore
that was equipped with a
solar pumping system.,
and provides water, for
house, stock and garden.
This PS200HR system with
256 Watts gives 4,800
litres a day at a total
head of 40m. |
 |
4 panels
tracking
This is another
PS200HR, 256 Watt
system, but with the
solar panels fitted with
a tracker to follow the
sun. This system gives
17,400 litres a day at a
total head of 15m. |
 |
6 panels fixed
This is a PS1200HR
system, fitted with 384
Watts of solar panels.
It pumps into 2 storage
tanks 500m away
providing stock water.
It provides enough water
per day for 140 head of
cattle at a total head
of 40m. |
 |
12
panels fixed
This is another
PS1200HR system, this
time fitted with double
the amount of power (768
Watts). This system
gives 5,800 litres per
day at a total head of
100m. |
 |
4
panels tracking on
free-flowing bore
This free-flowing
bore used to be able to
water the whole
property, but now only
dribbles over and has
insufficient pressure to
fill tank in photo. With
a PS600HR and 256 Watts
of tracking panels, it
is now putting out over
22,000 litres a day. |
 |
2
panels fixed
This PS200HR system was mounted on
the
windmill tower, supplementing windmill
supply from well.
Both windmill and solar
system pump out of same
well, and can both work
at the same time. The
mill is situated in a
gully and frequently
suffers a
"wind-drought". The 2
panels allow the solar
pump to pump 6,000
litres a day in addition
to what the windmill
pumps. |
 |
2
panels fixed
This system provides
stock water of 3000
litres per day at total
head of 25m. |
