Solar water pumping solutions are our main business. We have years of expierience in the following

  1. Supply of solar water pumps and DIY kits
  2. Installation of solar water pumps
  3. Supply and installation of the full range of Franklin Electric Solar & Grid based (AC) Water pump range
  4. Supply and installation of the full range of Lorentz, Grundfos, Taifu , etc Solar & Grid based (AC) Water pump range


  • Once off expense, years of free off-grid power and water supply. Even if the power is off you will still have water. Thus a secure source of life giving water supply.
  • No more fuel expenses and no need to cart around cans of diesel. The pumps pay for themselves in a few months just on the savings in fuel and effort.
  • Maintenance free, brushless, permanent magnet, low voltage DC motor, high efficiency, oil filled,  submersible water pumps. Stainless steel pump body, non-corrosion materials used throughout. Designed to be used in harsh and remote areas.
  • Ideal for areas where there is no eskom power available or where this is an expensive option to put up in terms of line and pole costs.
  • Used to supply water for people, life stock & crops. This includes drinking water for domestic use, animal watering spots/cribs and irrigation.
  • Can pump water from/to a borehole, well, aquifer, river, dam, tank, channel, etc.
  • Low level/dry run protection well prod, tank overflow prod, extra screw or impeller included.
  • The MPPT type control box ensures maximum power delivery to the pump. It also has a flow control limiter, fault protection, soft-start, over and under voltage protection as well as overload and over-temperature protection functionalities to ensure a long system lifespan.
  • SEG does the assembly, making of connections, adding of fitting, etc in-house. Just connect your pipe, plug in connectors and put the pump into the water, the rest is taken care off.



Solar water pumping works on a direct solar panel to pump energy conversion systems.

  1. A solar panel (or panel array) is connected to an
  2. MPPT type control box that regulates the current flowing to a
  3. Low voltage, high wattage, submersible DC water pump.




Information Required

To decide which pump is right for your purpose you need the following information:

  1. Total borehole depth: Ground level to the bottom of the borehole. The pump must never be to close to the bottom otherwise it sucks up dirt & debris that clogs and breaks the pump. Tested by lowering a weight down the hole attached to a rope, when the weight hits the bottom the rope slacks.
  2. Water height in the hole: also known as standing height. This is the level at which water is found in the hole. The pump must be placed at least at this level, but draw down of the water level as well as seasonal variability must also be taken into account. Our pumps have dry run switch off protectors to avoid pump damage if they do run dry. Measured by dropping a Smallish rock down the bore hole and counting the seconds until it hits the water. The rock falls at 1 meter per second.
  3. Run in/tank height: The height of the tank, run in, dam, etc above ground. This has to be added to the lift requirement of the pump. Ground level to the highest point the water runs into the reservoir. Also referred to as tank height. The closer the tank/reservoir is to the ground the less the pump needs to lift and the more water it will deliver per hour.
  4. Total head: the total height from the run in to the submerged depth of the pump. This is one of the two most critical measures as it determines the pump sizing.
  5. Horizontal pumping distance: Add 5m of lift per 100m horizontal distance or if there is an incline add the height difference (E.g. 5 meter height difference over 200meter = +5 meter).
  6. Reservoir/dam capacity: Size of the tank, reservoir, dam, etc. The reservoir must be able to handle the daily delivery of the pump.
  7. Tested delivery capacity: What is the tested delivery capacity of the borehole, dam, put, well, river, aquifer, etc deliver per hour/minute? Keep in mind that a borehole can become a dry well if more water is pumped from it than can be replaced by the ground water sources. Please ensure a tested figure is provided.
  8. Amount of water required: This is the amount of water required on a daily/hourly basis. On average there is 7 hours of sunlight per day that the pumping system can work. Thus is you require 3500 liters of water per day, you divide it by 7 = 500 liters per hour required. An average household required +/- 3000 liters of fresh water a day.


Pump Calculations

To determine which pump you will require, you will need to use the following calculations and provide us with the necessary information:

  • Step 1 – Total head height: Water level + draw down level + run in level + allowance for horizontal pumping distance = Total head height requirements

  • Step 2 – Water requirement: Domestic use + animal use + irrigation use + storage = Total daily requirement / 6 or 7 hours per day = hourly requirement.

  • Step 3 – Pump selection: We will assist you in selecting the appropriate pump for your purposes by looking at the above variables.
