Lorentz Pump Controller 200

The Lorentz PS200 eliminates the weakest links in solar pumping by using a helical rotor (progressing cavity) pump and a brushless, water-filled motor – No failure-prone diaphragms, no flooded-motor failures. no annual diaphragm replacement, no motor brush replacement, no delicate plugs that fail, no to pistons, cams, flapper valves, no to plastic parts, and no to electronics in the well. For submersible well applications where flow and depth are less challenging, for PV array wattages LESS THAN 300 watts and wells 165 feet (50 meters) or less.

PS200 Mini SOLAR WATER PUMP
"The World’s Most Economical Solar Pump"

• Lift from as deep as 165 ft (50 m)
• Maximum 3,785 gallons per day (10 m3)
• Mini 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
• Helical Rotor wet end, brushless motor (maintenance free)
• High resistance to sand and corrosion
• Fits 4" and larger well casings
• Wide voltage range for 24 to 48V systems (2-4 solar modules in series) Only one controller for solar direct or battery systems
• These systems use one of six pump/motor combinations depending on water temperature:
  HR-04-2, HR-04-3, HR-07-2, HR-07-3, HR-14-2 or HR-14-3 (see charts at the end of downloadable spec shhet below, to determine the appropriate pump for your conditions)

Controller Features

• Controlls the pump system and monitors the operating states
• Regulates 3-phase variable speed motor
• Mounted at the surface (no submerged electronic parts)
• Two control inputs for well probe (dry running protection), float or pressure switches, remote control, etc.
• Overload protection
• For solar direct systems: integrated Maximum Power Point Tracking
• For battery systems: low voltage disconnect and restart after battery has recovered
• Nominal voltage 24 to 48 VDC
• controller in sealed plastic housing

HIGH EFFICIENCY = LOWER COST
Mini pumps more water per watt than other solar pumps and KEEPS IT UP year after year.

RELIABLE AND MAINTENANCE-FREE
Mini eliminates the weakest links in solar pumping by using a helical rotor (progressing cavity) pump and a brushless, water-filled motor – No failure-prone diaphragms, no flooded-motor failures.

DEEP WELL APPLICATIONS
Mini can be submersed as deep as 165 ft (50 m). Submersion depth does not affect the performance or place additional stress on the pump or motor.

SURFACE WATER APPLICATIONS
Mini can be installed in a stream, pond, tank or shallow well, in any position.

DRY RUN PROTECTION
A low water probe (included) turns pump off to prevent dry-run damage. Reset is automatic after 20 minutes. The PS200 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
Mini 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 Mini to clean out a dirty well.

CONTROLLER DISPLAY
Lights indicate: system on, pump on, tank full, water source low, overload, and battery low.

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.

BATTERY SYSTEMS
LOW-VOLTAGE DISCONNECT prevents battery damage from overdischarge. This feature is included in the controller. Disconnect - Reconnect 22V–26V and 44V-48V

DROP PIPE
Pump has 1" NPT outlet. 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
The pump requires standard submersible cable, 3-wire + ground (total 4 wires). Connection to the pump is made using industry-standard splicing methods.

NEED MORE WATER or GREATER LIFT?
Consider the standard System PS600 or PS1200 the instead of the PS200 Mini system. These systems use more power, to pump as high as 760 ft (230m) or to produce a maximum of 34,000 gallons per day (120 m3). They are also appropriate for pressurizing applications. See separate specification sheets.
