Lorentz Pump Controller 1200

RELIABLE AND MAINTENANCE-FREE

PS1200 eliminates the weakest links in solar pumping by using helical rotor (progressing cavity) and centrifugal pump ends and a brushless and water-filled motor. No failure-prone diaphragms, no flooded-motor failures and no electronics in the well !

• Lift from as deep as 760 ft (230 m)
• Maximum 25,000 gallons per day (135 m3)
• PS1200 eliminates the costs of fuel, delivery, engine maintenance, and pollution.
• In many cases it COSTS LESS than a conventional pump and generator installation
• Great reliability and life expectancy
• High resistance to sand and corrosion
• Fits 4" and larger well casings
• Wide voltage range for 72 to 96V systems (6-8 solar modules in series)

DEEP WELL APPLICATIONS
The pump can be submersed as deep as necessary. Submersion depth does not affect the performance or place additional stress on the pump or motor.

SURFACE WATER APPLICATIONS
The pump can be installed in a stream, pond, tank or shallow well, inany position.

DRY RUN PROTECTION
An optional low water probe turns pump off to prevent dry-run damage. Reset is automatic after 20 minutes. The PS1200 Controller has an RPM limit adjustment to reduce the maximum flow rate to about 50 %, to help match a limited water source.

SAND AND SILT TOLERANCE
The pump has high resistance to wear from sand, clay, etc. that may occur in a properly constructed water well. However, a concentration of solids greater than 2 % (by volume) may cause blockage in the pump or the drop pipe, especially at low flow rates. Do not use the pump to clean out a dirty well.

CONTROLLER
MPPT, well probe and float-/remote switch terminals. Lights indicate: system on, pump on, pump speed, tank full, water source low, overload, and battery low. Protected against reverse polarity, overload and high temperature.

BATTERY SYSTEMS
Choose the PS600 System for 48V battery systems, or the PS200 for 24V or 48V battery systems.

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.

DROP PIPE
1" NPT pump outlet on most pumps—see sizing chart for specifics. If water is dirty, consider a smaller size drop pipe to increase the flow velocity. This helps exhaust solid particles and prevent accumulation in the pipe. When considering reduced pipe size, consult a pipe sizing (friction loss) chart. Pipe can be of any standard material, rigid or flexible. A torque arrestor is NOT required.

PUMP CABLE and SPLICE
Standard submersible cable, 3-wire + ground (total 4 wires). Connection to the pump is made using industry-standard splicing methods.
