 Lorentz Surface Pumps
These solar
operated pumps are designed for high reliability and life expectancy.
Maintenance free brushless DC motors. Excellent efficiency.
More powerful, quieter and more durable than plastic RV/Marine pumps.
Wearing parts typically last 5-10 years; overall life expectancy 15-20
years.
Pumps are supplied with IP54 weatherproof controllers suitable for
either PV direct operation with integrated maximum power point tracking,
or with a battery including low voltage disconnection and restart after
recharge. Two inputs for dry well probe, pressure switch or tank/remote
float switch. LED indicators for system status. Protected against:
overload, temperature, reverse polarity, lightning.
The max. pump speed is adjustable to reduce flow rate to approx. 30% if
desired. (20% for PS150)
In PV direct operation the maximum PV array size is unlimited as the
controller regulates max. power consumption.
Pressure switches and filters must be ordered separately.
Lorentz
PS600 Badu Top 12 DC Pump
 This solar
operated surface centrifugal pump is ideal for use with:
Swimming pool water circulation;
Irrigation;
Pond management;
Aquariums
Data Sheet
Either for direct solar operation with a PV array of nominal voltage
48-72 V (150 V max. open circuit voltage) or from a 48V batttery.
Max. power consumption 600W.
Max. suction lift: 3m.
Lorentz
PS150 Boost Pump
 This pump provides city water
pressure anywhere. Suitable for:
Drinking water supply;
Water purification & filtration;
Pressurising home water systems;
Drip irrigation.
Data Sheet
Uses solar
power to give 250-10,000 litres per day from shallow water sources. Can
boost water as high as 140m.
For 12 or 24 VDC systems.
Designed to draw water from shallow wells, springs, cisterns, tanks,
ponds, rivers and streams and push it through long pipelines. Slow
pumping minimises the size and cost of solar array-battery system, wire
and piping.
Simple installation with high reliability and life expectancy.
Max lift 140m. Max flow 900 litres/hour.
Max suction lift: 5m, pump should be placed as low and as close to water
source as possible.
Max power consumption 200W.
Can tolerate sea water & disolved minerals but is not suitable for dirty
water, water must be filtered clear.
