For outdoor projects in Australia that need water flow, submersible water pumps are a valuable and popular choice. Not only do wells utilize them, but they are also commonly found in water gardens, waterfalls, ponds, fountains, and other varying lawn features that have spouts. The pumps are an economic means of circulating water in lawns and other varying features. They are not only completely noise-free and fully submerged in water, but they could also be utilized for in draining ponds too. For all projects, you must size your pump most appropriately. This article takes a close look at some of the basic recommendations you should follow when sizing your pump.

  • The capacity of well: One among the most obvious measurements you require in sizing your pump is the project or well’s capacity. The larger your well, the greater the pump requirement. Nevertheless, modifications could sometimes be made to the pump to fix insufficient water capacity.
  • The manufacturer’s performance curve: It is crucial to attain a balance within the manufacturer’s operational parameters on the pump. There have to be optimal efficiency specifications the manufacturer has indicated, and the pump has to be sized to work within such specifications, also called the manufacturer’s ‘performance curve’.
  • Water velocity: You have to be capable of measuring the velocity of water that will be flowing past the pump’s motor. Some cooling regulations are demanded by the flow and pumping requirements of virtually all submersible pumps in Australia. If the flow is insufficient to meet the set cooling regulations, then you might have to install a flow inducer.
  • The temperature of the water: The temperature of the water is crucial if you are going to be pumping really hot water, and you will require a motor horsepower that is rated when pumping water at some elevated temperatures.
  • Pumping level: One other crucial sizing specification is the pump’s pumping level. You should be capable of performing tests to determine the pumping and drawdown level for your pump.
  • The loss of friction: The calculation of friction loss is based on the size of the pipe and flow rate which is already taken into consideration when sizing a water pump, as well as runs.
  • Total dynamic head (TDH): You will require the TDH minimum and maximum when sizing your water pump.

The importance of properly sizing your water pump

The proper sizing of your water pump is quite crucial to obtaining a properly functioning system. The pump’s total head and pumping capacity form its engineering curve, which has to be an incomplete balance to operate successfully. If your pump is undersized, there will be too much head against it. If it is oversized, the head against it will be too little. Attaining an optimal balance is crucial to its proper functioning.

These are the foremost recommendation to be followed when it comes to properly sizing submersible pumps. If you are having any problems in sizing yours, then you might have to speak with a well-water professional. Such experts will be able to guide and advise you as regards’ water pump sizing.
