In Part 1 we had a look at the different kinds of water pump available. In this post we will look at some of the pump applications that are common for engine driven pumps.
If you want a pump to use for home fire protection then it is essential to be able to power your pump without mains electricity. This means either a generator to power an electric pump, or the simpler solution of an engine powered pump. Mains electricity is usually lost during a bushfire so it is very important to have an independently powered pump (read more about defending your property from bushfires).
Moving water from one place to another, whether it is from a dam, tank, construction site, building or some other source of water. The key considerations for this application are what level of pump performance you require (dealt with in the next section), and whether you need to move your pump from place to place.
Dirty or debris filled water
If you are moving water that contains solids or debris then a trash pump is the ideal choice. They are designed to safely move water containing solids (up to certain sizes). This makes them well suited to dewatering worksites, and moving flood water.
Moving effluent or chemicals
Some chemicals, or contaminated water such as salt water and effluent can be damaging to certain pumps. A chemical resistant pump is made from materials that are corrosion resistant, such as plastic or stainless steel. If a chemical resistant pump is required, it is recommended to determine which materials are safe. These are commonly used for agricultural and industrial chemicals.
Providing water to buildings and gardens
The most common type of pump for these applications is an electric variant, with or without a jet. These pumps typically need to be able to run for long periods, and be ready on demand, so being powered by your electricity grid is ideal. There is a wide range of high quality options for this type of application.
