What Are The Main Types Of Water Pump?

Are all water pumps created equal? After all, what they all do is move water from one place to another. While a few of decades ago the choice of pumps was rather limited, today a contractor can get lost trying to choose the right one for the project. Knowing the main types of the water pump can help you get started.

If you still have some questions about the water pump type for your needs after you read the article, our experts can help you make the right choice.

Choosing the wrong pump type can lead to bad performance and a quick breakdown. The type of a pump you need depends on the type of liquid you are planning to move. Evaluate your job site to find out what type of water you are dealing with.

1) Mostly Clear – Centrifugal Pump

If you need to pump more or less clear water, you can take advantage of a centrifugal pump. The water doesn’t need to be absolutely pure to be pumped out. If some debris gets inside the pump, a strainer will take care of it. However, if there are visible pieces of rubbish in the water, this pump won’t cut it. In fact, you’ll end up with a broken piece of equipment.

2) Slightly Littered - Semi Trash Pump

Is the liquid you are dealing with sandy, muddy or littered with debris? The centrifugal pump won’t do the job. A semi-trash pump is specifically designed to deal with slightly dirty liquids at constructions sites. This pump can move the debris around 2 cm in diameter.

Semi-trash pumps are slower, larger and heavier than centrifugal pumps. However, unlike the centrifugal pumps, they can deal with debris without failing. If you are not sure the centrifugal pump can handle the debris you are seeing, opt for the semi-trash pump.

3) Substantially Soiled – Trash Pump

When the semi-trash pump doesn’t cut it, call in the cavalry. Trash pumps can deal with fairly large pieces of debris, stones, sticks, and more. They can easily pump the water with debris 2 to 3 cm in diameter. Highly sandy and muddy water is the perfect target for the trash pump.

Construction workers often choose trash pumps for their needs since it can overcome a majority of obstacles found in the excavation site water. Trash pumps are usually heavier, larger, and slower than semi-trash pumps.

4) Tough Spots – Diaphragm Pump

Diaphragm pump has many names, including the “mud pump”. This water pump type is designed for the toughest spots, where the water is so muddy you can’t even see how dirty it is beneath the surface.

These pumps deal with debris up to 5 cm in diameter. While this pump is larger and heavier than other types, it’s also pricier. It works about four times slower than the trash pump.

Choosing the wrong water pump type leads to breakdowns, pricey repairs, and project delays. Be careful about choosing the right type for your job.
