Lorentz Surface & Pool Pumps

Bookmark and Share

These solar operated pumps are designed for high reliability and life expectancy. Maintenance free brushless DC motors. Excellent efficiency.

More powerful, quieter and more durable than plastic RV/Marine pumps. Wearing parts typically last 5-10 years; overall life expectancy 15-20 years.

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.

Remote monitoring with Lorentz PS data module and pump scanner app

PS150 Boost

This pump provides city water pressure anywhere.

  • Suitable for: Drinking water supply;
  • Water purification & filtration;
  • Pressurising home water systems;
  • Drip irrigation.

Uses solar power to give 250-10,000 litres per day from shallow water sources. Can boost water as high as 140m.
For 12 or 24 VDC systems.

Designed to draw water from shallow wells, springs, cisterns, tanks, ponds, rivers and streams and push it through long pipelines. Slow pumping minimises the size and cost of solar array-battery system, wire and piping.
Simple installation with high reliability and life expectancy.

Max lift 140m. Max flow 900 litres/hour.
Max suction lift: 5m, pump should be placed as low and as close to water source as possible.
Max power consumption 200W.
Can tolerate sea water & disolved minerals but is not suitable for dirty water, water must be filtered clear.

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.

  • Max. voltage 250 VAC / 220 VDC
  • Max. current 2A
  • Max. power 60 W / 62.5 VA
  • IP 54
  • 4m cable
  • Powers itself via the PV module on the back
