Lorentz Solar Pump PS1200

Formerly Dankoff ETA Pump

Lorentz Solar Water Pumping Systems are some of the most efficient pumping systems in the world. The unique 3-Phase motor design allows you to harness the sun for all your pumping needs. All Lorentz Pumps can be utilized with Solar direct or battery powered system operation.

	Pipeline and Irrigation

PS1200 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 92 % (motor + controller)
	Enclosure: IP 54 (sealed, weatherproof)

Pump End (PE)

	High life expectancy
	Non-return check valve
	Dry running protection (optional)
	Material: stainless steel (AISI 316), rubber

For HR Pumps only

	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 1200 HR/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

1 1/4�, 1 1/2� 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: Specify temperature class on order Class 1 46 �F to 72 �F (8 �C to 22 �C) Class 2 64 �F to 90 �F (18 �C to 32 �C) Class 3 82 �F to 108 �F (28 �C to 42 �C)
	Controller: ambient temperature -22 to +131 �F (-30 to +55 �C)

Warranty

2 years manufacturer�s warranty against defects in material and workmanship
