At Rand Water Boring, we believe that providing choices to our customers is a vital part in ensuring 100% customer satisfaction. Below you will find the different types of borehole pumps, as well as a step-by-step process outlining exactly how we install our pumps on your property.

Different Types Of Borehole Pumps

Submersible Pumps

These pumps have to be fully submersed in the water in order to draw in the water and pump it to a particular location. A submersible pump is typically used where there is ample water to cover it, and this type is often used for groundwater supply, drainage, domestic water supply, and pumping towards a filter.

They are not often used in boreholes, because boreholes tend to be long and narrow. However, where there are underground water resources that provide easy access for a submersible pump, they can be used very effectively.

Borehole Water Pumps

The natural shape of a borehole is long and narrow. A drill is used to penetrate deep into the soil and to locate a water source. Then a pump that fits the size of the borehole must be used to pump out the water. Often, a test pump is installed first in order to determine the yield and the amount of power needed for the pump, and only after that can the appropriate, and permanent, borehole water pumps be installed. Borehole water pumps are relatively easy to maintain and quite cheap to run, and a reliable pump can provide you with many years of hassle-free water!

Installation Of Borehole Pumps

  • Once the correct wet end and motor have been selected, they are attached together with nuts and bolts.
  • A Waterproof joint kit is then used to join the motor lead out cable to the submersible cable. The length of the submersible cable is determined by how deep the hole is. This cable is specifically designed to be installed underwater.
  • Wellzarc filter (designed and manufactured by the Pump & Irrigation Centre) is installed onto the borehole pump using a heat shrink unit. This filter prevents borehole debris from entering and damaging the wet end and also serves as a cooling sleeve.
  • High-density piping class 12 or 16 together with plasson and galvanized fittings is used to connect the pump from the bottom of the hole to the top. The piping must be heavy-duty as it not only used to convey water but serves as a support for the pump.
  • Nylon rope is also attached to the pump to serves as back-up support.
  • At the top of the hole, a galvanized base plate is installed onto the piping and rests on the galvanized sleeve of the borehole.
  • A control valve is installed onto the supply piping to prevent the pump from operating beyond its optimum operation rating.
  • Armored cabling is used to supply power from the control box to the motor. A weatherproof box is used to connect the armored cable to the submersible cabling.
  • Cast iron manhole cover or heavy-duty plastic enclosure is used to cover the borehole components at the top of the hole.
