Key Facts
- Water pumps, also called motor pumps, are indispensable tools to move large amounts of water from one area to another in a controlled manner. These machines are fast and efficient and can be used for domestic use, fish farms, and swimming pools or for emergency use to remove clean or dirty water.
- Water pumps are powered by either electricity (for electric pumps) or fuel. It is useful for increasing water pressure and therefore letting us make the most of this precious resource.
- These days, manufacturers have developed water pumps to be compact and light and in order to comply with the appropriate safety requirements at home while also saving on energy consumption.
Our selection: The best motor pumps on the Australian market
It’s not easy to choose the most appropriate water pump, as there is a great variety available on the market today. You need to consider what tasks you need to do and what benefits it should have. It is not the same if you want to empty a swimming pool, compared to if you want to drain dirty water. We have carefully compiled this selection of water pumps to help you find the right one for you.

What is a motor pump exactly?
How do water pumps work?
A very common mistake about water pumps is to think that they create pressure. Actually, they only displace the liquid causing it to flow from one area to another.
Why would you need a water pump?
- Drain water from a basement
- Extract water from a well
- Move water from one place to another, even at different ground levels
- Increase the pressure or water flow
- Empty and fill pools, ponds or whirlpools
- Drain shallow areas that are flooded or contaminated by dirty water
- Water lawns or agricultural areas in a traditional way or by sprinkling.
- Distribute fertilizers and pesticides.
- Perform various tasks in the area of construction.
- Help in catastrophes such as fires or floods.
How do you measure the efficiency of a water pump?
In the case of domestic systems (irrigation or swimming pools), it is necessary to make sure that the flow and pressure supplied by the water pump are sufficient for the installation to work properly. If you are unsure, it would be better for a professional to calculate it for you.
What types of water pumps are there?
| Type of water pump | Uses |
|---|---|
| Surface | Let you remove water from wells or tanks which are several metres deep. |
| Submergable | Extracts water from very deep place which are inaccessible by surface pumps. |
| Pressure | Allows greater irrigation and better circulation of water in order to reach all taps. |
| Bail pumps | Used to evacuate and transfer water. Runs on a system which automatically turns the pump on or off depending on the water level in order to stop it from working when dry and overheating. |
Why do you need different pumps for dirty and clean water?
Can I use the same pump for clean and dirty water?
- Water pump for clean water: It is important to know if we need a piece of equipment to irrigate, to empty pools or simply to transfer clean water from one place to another. Surface water pumps are ideal for working with these types of water.
- Pump for dirty water: Must be able to filter particles of different sizes. It is better to look for equipment with very large hose diameters, to avoid clogging. Submersible water pumps are ideal for working with dirty water.
What essential components do we find in a water pump?
In general, water pumps have the following components:
- Motor: This is a fundamental component that drives to move the shaft and the impeller to generate the movement of the water. Its power capacity will determine the speed at which the water will flow.
- Housing: This is the body of the pump. It covers the water feeding mechanism and is commonly made of stainless steel or cast iron to prevent corrosion and rust.
- Conduits: These are the channels through which the water is circulated. Water or liquid comes in through the “inlet” and goes out through the “outlet.”
- Control panel: These are the switches and buttons used to switch the pump on or off.
- Starting rope: This is a rope that must be pulled to start up the pump’s combustion engine.
- Impeller or rotors: These can be blades, vanes or rotating vanes.
- Seals and rings: These are used to sealing off the pump in order to generate internal compression.
- Bearings: These are parts that adequately support the impeller shaft.
What safety precautions must be followed when using gasoline or diesel for motor-pumps?
Shopping criteria
While there are many factors to consider it is essential to first be clear on what you want to use the pump for and how often it will be in operation. There are a few other factors to consider as well. These are:
Materials and safety
Water pumps are not dangerous machines in themselves, but reckless use can cause accidents. Many of these accidents can be avoided if the housing materials are of good quality. In general, it is recommended that pumps have covers made of stainless steel and cast iron. In addition to being robust, they prevent the water pump from rusting or corroding due to the action of water.
Water flow
It will be necessary to analyse the work the pump will have to do to make sure you buy one with the right capacity and power. The amount of water with which we want to pump must be equivalent to the pumping capacity of the water pump we are looking to buy. High water flow is not necessarily better, or even appropriate. To make the right decision, it is important to carry out a thorough analysis of your work site and determine how much and what type of water you will be pumping
Fuel efficiency
As almost all water pumps work with fuels like gasoline or diesel you should consider the equipment’s capacity. This will allow it to work at its greatest efficiency levels. It is recommended that the water pump must have at least a 1-litre tank.
Motor power
The engine of a water pump is an important factor to consider as this would determine how fast it can shift water or other liquidsThis is the part of the machine which most effects its quality. The more power the engine, the greater the rate of water flow. This makes it a critical factor when choosing a pump.
Manouevrability
Many water pumps are heavy but as they have become more popular for household use they have been designed to be easily transportable and easy to carry around. Make sure that the water pump you want to buy have handles and grips to make carrying easier.
Summary
Pumps are essential equipment for those seeking to transfer large amounts of liquids, especially water. Pumps with gasoline or diesel engines are easy to use, easy to transport and can be used around the house. Water pumps are designed for specific uses and specific models should be acquired depending on whether a surface or submersible pump is needed and also depending on the type of water that will be involved.
Surfaces, pressure, bilge or submersible, are ideal to deal with clean or dirty water, depending on your requirements. Water pumps are very useful for irrigation systems, emptying swimming pools, evacuation of septic tanks or cisterns, and can even be used to clean up or prevent flooding.
