Lorentz PSK AC Solar Water Pump
Lorentz PSK System Overview
- lift up to 520ft.- flow rate up to 578 GPM
- simple installation
- maintenance free
- high reliability and life expectancy
- cost-efficient pumping
- 2 years manufacturer's warranty against defects in material and
workmanship
Applications
- drinking water supply
- livestock watering
- pond management
- pipeline and irrigation
- irrigation
- Etc.
PSK Controller
- controlling of the pump system and monitoring of the operating
states
- mounted at surface (no submerged electronic parts)
- two control inputs for well probe (dry running protection), float or
pressure
switches, remote control etc
- automatic reset 20 minutes after well probe turns pump off
- protected against reverse polarity, overload and high temperature
- data logger for historical dates: running time, starting/shut down
time of day, max. power/voltage of day, accumulated energy of day
etc.
- solar operation: integrated MPPT (Maximum Power Point Tracking)
- battery operation: low voltage disconnect and restart after battery
has recovered
- display of current running data such as: input/output current/power/voltage, pump speed, temperature speed control selectable,
max. and min. speed
- input: Voc 750 VDC, Vmp 500 VDC
- output: 400 VAC 3-phase, 30-60 Hz
- max. efficiency 97 %, advanced IGBT
- enclosure: IP 41 (sealed, weatherproof)
- ambient temperature: -10 to +45°
AC 3-PhaseDrive Motor
- corrosion-resistant, all stainless steel exterior construction
- stainless steel splined shaft
- NEMA mounting dimensions
- hermetically-sealed windings
- water lubrication
- pressure equalizing diaphragm
- max. submerged depth: 2,260 ft
- max. water temperature: 30°C/86°F
- PH value: 6-9
- IP 68
Pump end (PE)
- centrifugal mulistage direct-coupled pump end
- non-return valve
- material: stainless steel (AISI 304), rubber
- dry running protection (optional)
- max. sand content: 50 g/m3, a higher content will wear the pump and reduce its life span considerably
- max. salt content: 300-500 ppm at max. 30°C/85°F, higher salt contents require lower water temperatures
- pH value: 6-9
- high life expectancy
