Everyone knows what I mean when I mention a water pump. But what a lot of people don’t realise is that there are numerous types of water pumps for different situations. And when we go deeper into the subject, less and less people will actually understand what I’m explaining. And the most simple questions will pop into your minds. For example: what type of pump do I need? Why would i need a water pump? Or even something like how does a water pump work? Well, fear not. For I’m going to briefly simplify it for you in this article
Water pumps can easily be split up in 2 categories: centrifugal and positive displacement. If these two don’t mean anything to you, don’t worry. I’ll explain them with some examples.
A centrifugal water pump uses a rotating impeller to move the water into the pump and pressurize the discharge flows. These types of pumps must always be manually started but work with every type of water. Centrifugal water pumps are often used in water system applications and construction, in addition to dewatering. They’re also often used to pump water supplies in large buildings and to pump water from domestic wells. A good example of a centrifugal water pump is your washing machine.
Positive displacement water pumps deliver a fixed amount of flow through the mechanical contraction and expansion of a flexible diaphragm. Positive displacement pumps are used in many industries that manage high-viscosity liquids and where sensitive solids may be present. They are recommended for applications requiring a combination of low flow and high pressure. A great example of this type of pump is the booster pump.
It’s perfectly understandable that subjects like these confuse or bore you. If this article didn’t make your choice easier you can always contact our helpdesk to hear some further explanation.
