Lorentz Submersible Pumps

Bookmark and Share

These solar operated pumps are designed for high reliability and life expectancy. Helical rotor (HR) or centrifugal (C) models with maintenance free brushless DC motors. Excellent efficiency. High resistance to sand and corrosion.

They are supplied with IP54 weatherproof controllers suitable for PV direct operation with integrated maximum power point tracking. This also allows pumps to be used with a battery and includes low voltage disconnection and restart after recharge. A separate charge controller is required to prevent battery overcharge.

  • Two inputs for dry well probe, pressure switch or tank/remote float switch.
  • LED indicators for system status.
  • Protected against: overload, temperature, reverse polarity, lightning.

The max. pump speed is adjustable to reduce flow rate to approx. 30% if desired. (20% for PS150)
In PV direct operation the maximum PV array size is unlimited as the controller regulates max. power consumption.

Solar panels, Float/Pressure switches and filters must be ordered separately.

To give you an idea of the savings to made compared to a diesel solution please take a look at the Lorentz Solar v Diesel Calculator.

Lorentz Sun Switch

The Lorentz Sun Switch is used to switch depending on solar intensity. One of the main uses is to reduce wear on the pump and motor by setting the Sun Switch so that the pump will only start when it is likely to continually to run throughout the day.
