Lorentz PS200

Characteristics 

• Lift up to 165 feet (50 m) 
• Flow rate up to 9.5 gpm (2.7 m3/h) 
• Simple installation 
• Maintenance-free 
• High reliability and life expectancy 
• Cost-effective pumping solution

Application 

• Drinking water supply 
• Livestock watering 
• Pond management 
• Irrigation

PS200 Controller 

• One controller for array direct or battery powered operation, with system status indication 
• Mounted above ground (no submerged electronic parts) 
• Two control inputs for well probe (dry run protection) and remote control (float or pressure switch) 
• Automatic reset 20 minutes after low water protection engages 
• Protected against reverse polarity, overload and high temperature 
• Speed control, maximum pump speed adjustable to reduce flow rate to approximately 30 % 
• Solar operation: integrated MPPT (Maximum Power Point Tracking) 
• Battery operation: low voltage disconnect and restart after battery has recovered
• Max. efficiency 88 % (motor + controller) 
• Enclosure: IP 54 (sealed, weatherproof)

Pump End (PE) 

• Helical rotor pump (positive displacement pump) 
• Two main parts only: stator and rotor, field serviceable 
• Stator: geometry made of abrasion resistant rubber 
• Rotor: stainless steel, hard chrome plated, abrasion resistant 
• More resistant to damage by sand than other pump types
• Self-cleaning

Motor ECDRIVE 600 HR/200 C 

• Brushless DC motor 
• No electronics inside motor 
• Water filled 
• IP 68, pressure balanced, max. submersion unlimited 
• Dynamic slide bearings, material: carbon/ceramic 
• Wetted material: stainless steel (AISI 316), POM, rubber, cable drinking water approved

Sand and Silt Tolerance

• The pump (HR) has a higher resistance to wear from sand and clay than any other pump type. In properly constructed wells the amount of sand and clay is within the tolerance of the pump.
• 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.

Pump Cable and Splice 

• Standard submersible cable, 3-wire + ground (total four wires). Connection to the pump is made using industrystandard splicing methods.

Drop Pipe 

• 11/4”, 11/2” or 2” NPT pump 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.

Temperature Limits 

• Pump end, motor: water temperature up to +104 °F (+40 °C)
• Specify temperature range on order 
• Controller: ambient temperature –22 to +131 °F (–30 to +55 °C)

Warranty 

• 2 years manufacturer’s warranty against defects in material and workmanship
