PS1200 HR-10 Submersible Solar Pump System

  • Lift up to 30 – 80 m
  • Maximum flow rate up to 1.9 m³/hour “Helical Rotor “
  • Cost efficient pumping
  • Maintenance free
  • High reliability and life expectancy

LORENTZ was established in Hamburg, Germany and has been a quality designer and manufacture of Solar Pumps since 1993. Through the innovative electronic controlling, outstanding manufacturing quality and a simple design, Lorentz have managed to reduce the high cost of solar water pumping. Their submersible helical rotor pumps consist of only two parts, Lorentz’s brushless motors are water filled and maintenance free, while the electronics are NOT inside the submerged motor but easily accessable on the surface.

Applications

  • Drinking water supply
  • Livestock watering
  • Pond management
  • Irrigation
  • Windmill replacement
  • Dams, creeks, rivers and tanks

Warranty

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

Features

Controller PS1200

  • controlling of the pump system and monitoring of the operating states
  • Mounted at surface (no electronic parts submerged)
  • 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
  • Speed control, max. pump speed adjustable to reduce flow rate to c. 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)

Motor ECDRIVE 1200HR / C

  • Brushless DC motor
  • No electronics inside motor
  • Water filled
  • IP68, pressure balanced, unlimited submersion
  • Dynamic slide bearings, material: carbon/ ceramic
  • Wetted material: stainless steel (AISI316), POM, rubber, cable drinking water approved

Pump End – PE

  • High life expectancy
  • Stainless steel none-return valve
  • Dry running protection
  • Material: stainless steel (AISI 316), rubber

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

Water Temperature Ranges

Please Choose Water Temperature Classes “X” from following before purchases HR pumps

X = 0 For water temperature between 0 to 10 degrees celcious
X = 1 For water temperature between 10 to 20 degrees celcious
X = 2 For water temperature between 20 to 30 degrees celcious
X = 3 For water temperature between 30 to 40 degrees celcious
X = 4 For water temperature between 40 to 50 degrees celcious
