This brief overview will only deal with the most common pumps: Pressure pumps and Submersible Pumps.
Buying the right pump for the job is most important and most people wouldn’t be able to make that decision on their own.
There are a lot of factors that come in to play when it comes to selecting the right pressure pump.
The first question is: what’s the pump going to be used for?
For example, is it just going to be connected to a water tank so a garden hose can be attached to it so as to water the garden and wash the car or maybe it’s going to drive an irrigation system and if so, is it a drip irrigation system or a sprinkler system.
Is the pump going to be used to flush the toilets and feed the washing machine or is it going to do all the above as well as provide water to the bathroom for the basins, shower and kitchen?.
If it is going to be providing water inside the house then is it single story or multiple stories and how many toilets and bathrooms are involved.
Answers to the above will help determine the flow, pressure and type of pump required for the job.
The higher the flow and pressure required, the larger the pump and also the price.
For general purposes most pumps are fitted with an automatic controller which turns the pump on and off depending on demand. Without a controller, the user would have to turn the power on manually each time and turn it off when finished and who wants to do that? Most controllers also have loss of prime protection stopping the pump from getting damaged if no water is available.
The main purpose of a pressure tank connected to a pump is to stop a pump cycling (IE the pump turning on and off all the time when small amounts of water are required).
An example of where a pressure tank would be used is where a pump is being used to feed water to a house. If an Automatic controller was used to turn the pump on and off every time when someone wanted a small amount of water, the pump would have to turn on to send the water to the tap and turn off again when the tap is turned off.
However if a pressure tank was fitted it would feed small amounts of water to the tap from the tank without having to turn on the pump. The amount of water held in the pressure tank varies with the size of the pressure tank. A pressure tank is a great energy saving device minimising the amount of time the pump turns on over its life. It will also prolong the life of the pump.
When a home or property is connected to a water tank to supply its water, a switching controller is normally connected to the pump for the sole purpose of automatically switching the water source from the water tank to the mains when the tank runs low on water.
When the tank is topped up again with water it will switch back to the tank.
Submersible pumps, commonly termed sump or drainage pumps are actually submersed in or under the water as opposed to being on dry ground. They suck water in through their inlet(s) at the bottom and force it out through a hose or pipe.
Some drainage pumps are designed to only pump clean water whilst others are designed to dirty water some can even handle sewerage and other larger solids.
Once again, it’s best to speak to an expert so that you can be guided to the correct pump for your application. Questions like: What’s it being used for, what type of liquid is it going to be pumping, how deep will it be submerged, how high and how far has it got to pump to, will be amongst the first asked.
