Selecting the best water pump solution for your needs is vital to ensure you have the right size pump for the job at hand. You need to understand a few factors when considering water pumps such as:
Clean Water vs Grey Water vs Dirty Water
The Application of the Water Pump
The Size of the Dwelling using the Water Pump
The Volume of Water Required
The Type of Water Pump
1. The Water type passing through the Water Pump
To select the best Electric Drinking Water Pump wholesales for your needs, you must identify the type of water you will be dealing with. The 3 key types are outlined below:
Clean Water is Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation. Often sourced from mains water supply to homes. Meets AS4020 standards.
Greywater is typically water from rain collected off roofs as well as re-usable wastewater from washing machines, showers and other sources. Greywater replaces the need to use mains water for watering gardens or lawns and can potentially save thousands of litres of drinking water.
Dirty Water is typically water that contains small particles. Used for watering gardens or lawns which can potentially save thousands of litres of drinking water. Includes rain or greywater.
2. The Application of the Water Pump
Water Transfer pumps are built for use in multiple applications for water supply and the transfer of water. Applications include
3. The Size of the Dwelling using the Water Pump
What size household, or other dwelling, is using the water pump? A single storey dwelling will have different needs to a double storey dwelling.
Smaller homes will likely have less taps in use and thus would have different needs to a larger home, which would have more taps in use and various combinations.
Also, if you need to account for outside watering or irrigation you need to include this when considering the dwelling size for your water pump.
4. The Volume of Water Required
To understand the volume of water required within the dwelling that is running the water pump, you will have to work out the number of taps or outlets, both inside and outside, that are likely to be in use simultaneously.
Keep in mind that different outlets will have different flow rates.
To work out your household water flow rate you can measure the time it takes to fill a bucket from each tap or outlet.
Flow Rates at Fixtures or Appliances
The flow rates to fixtures, appliances, taps, valves and cisterns shall be not less than the flow rates specified below.
The maximum flow rate from a shower, basin and kitchen sink or laundry trough outlet shall not exceed 9 L/min.
5. The Type of Water Pump
When it comes to water pumps, there are a few types including Jet Pump, Multi-Stage Pump, Submersible Pump and Circulation Pump.
Jet Pump Powered by an electric motor that contains and drives an impeller/centrifugal pump. The impeller moves water, through the Jet Pump and increases the pressure of the water, to assist in areas where high suction lift is required (e.g. double storey homes).
Multi-Stage Jet Pump A centrifugal pump containing two or more impellers is called a multi-stage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts. For higher pressures at the outlet, impellers can be connected in series. For higher flow output, impellers can be connected in parallel. Multi-stage pumps are quieter and ideal for applications where low noise levels are required.
Submersible Pump A submersible pump is a device which has a hermetically sealed motor close-coupled to the pump body where the whole assembly is submerged in a water tank or pit. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump and the fluid surface. Submersible pumps push fluid to the surface as opposed to jet pumps having to pull fluids. Submersibles pumps are more efficient than jet pumps.
Circulation Pump A circulation pump is a specific type of pump used to circulate hot water in a closed circuit within a house or apartment. They are very efficient because they only need to distribute liquid within a closed circuit to overcome the friction of a fixed internal piping system.
