All You Need to Know About the Types of Industrial Water Pumps

Water pumps are used in different settings. They come in different types, sizes, and configurations to suit different water pumping requirements in homes, commercial properties, and different industries. Industrial water pumps, among all kinds, have advanced features designed for the unique demands of various sectors and businesses. Here are some bits of information about industrial water pumps:


Industrial pumping machines are commonly used in the construction industry. They are usually found in construction sites where there is a need to remove excess water. These pumps are very useful in areas that experience heavy rains, which may cause flooding and where stagnant water can cause disruption to work. With the help of water pumps, the accumulated water can be quickly removed so that the construction project carries on.


Water pumps come in different types. They can be categorised according to how they operate. According to reliable industrial water pump suppliers, pumping machines can be manual, electric, hydraulic, or gas-powered. Based on how they move water, pumps can be categorised as centrifugal and positive displacement pumps. Both kinds are meant for the continuous transfer of water from one place to another.

In a centrifugal water pump, a rotating impeller is used to move water into the machine and apply pressure to discharge it. These pumps come in different models such as standard, trash, and submersible. Centrifugal pumps provide a high flow rate. They are not only used for water but also for other types of liquids with low viscosity or those that are considered thin liquids.

Positive displacement pumps are also known as rotary pumps. They use mechanical force to contract and expand their flexible diaphragm. They are designed to deliver a certain amount of flow and used in moving liquids with high viscosity, such as those that may contain solid materials. Unlike centrifugal pumps, positive displacement pumps offer a low flow rate, and they are perfect for high-pressure applications.

Choosing your pump

When choosing between centrifugal and positive displacement pumps, it pays to start by knowing their applications and advantages.

Centrifugal water pumps are not only used for dewatering on construction sites. They are also useful in pumping water supplies in residential and commercial buildings. They match well with pneumatic systems and applications that do not require suction lifts. These pumps are used in domestic wells and in fire protection systems, too. One drawback of centrifugal pumps is that they need recirculating liquid to avoid overheating that may occur because of low flow rates. They have to be filled with the pumped liquid to work efficiently.

Positive displacement water pumps are favoured because they get rid of air from the lines, minimising the requirement for air bleeding. The problem with them is that they need very little space between the rotating pump and the unit’s outer edge. This means very slow rotation. While you can increase the speed level, the pump may not work as effectively due to liquid erosion.

Many industries rely on centrifugal and positive displacement pumps for their dewatering and water transfer needs. They are designed for different applications and have a fair share of disadvantages. When you’re looking to buy a unit, it’s wise to consult a reliable supplier to learn about your best option.
