Submersible solar pump, centrifugal type, for flow rates up to 37,860 US Gal/h and lifts up to 600 ft.

System Overview

• lift up to 600 ft.
• flow rate up to 581 GPM
• fast, failure-free installation
• excellent serviceability
• high reliability and life expectancy
• short Return of Investment (ROI) cycle
• lower Total Cost of Ownership (TCO)
• 2 years manufacturer's warranty against defects in material and workmanship

Applications

• drinking water supply
• livestock watering
• pond management
• 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
• data logger for historical dates: running time, starting/shut down time of day, max. power/voltage of day, accumulated energy of day etc.
• speed control selectable, max. and min. speed
• integrated MPPT (Maximum Power Point Tracking)
• input: Voc max. 750 V DC, Vmp min. 500 V DC
• output: 400 V AC 3-phase, 30 – 60 Hz
• max. efficiency 97 %, advanced IGBT
• enclosure: IP 41 (sealed, weatherproof)
• ambient temperature: –10 to +45° C

AC 3-Phase Drive Motor

• 3-phase AC motor
• corrosion-resistant construction
• stainless steel splined shaft
• EMA mounting dimensions
• hermetically-sealed windings
• water lubrication
• pressure equalizing diaphragm
• max. submerged depth: 700 m/2,300 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

Safety Features

• Protection against:
  
  • over current
  • under voltage
  • over speed
  • over temperature
  • reverse polarity
  • low water
