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


Lorentz Badu Top 12This 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


Lorentz PS150 BoostThis 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.
