There are plenty of water pump types on the market but not each is suitable for every occasion.

The purpose of a water pump is to dewater and minimise the downtime when it comes to serious rain events. 

Understanding which type of water pump is best for each and every occasion is essential if you are looking to reduce the operational costs whilst increasing the system's performance. The evaluation should be done based on durability, performance, price and low downtime.

Types of water pumps

There are two main types of water pumps; positive displacement and centrifugal water pumps. Both water pumps serve the same purpose, however, when it comes to your project's specific needs, they do have different options. Choosing the right one, completely depends on the type of project that you need to cater for.

Positive displacement water pumps

Positive displacement water pumps can manage high viscosity liquids and they are perfect in many industries. This type of water pump is very efficient when it comes to the need to bleed the air from the lines. The positive displacement water pump should be operated at slow speeds and the clearance between the outer edge and the rotating pump should always be close to avoid the erosion of the liquids.

Centrifugal water pumps

Submersible, trash and standard are the three different alternatives to centrifugal water pumps. They all use a rotating impeller to move the liquids into the pump in order to pressurise the discharge flow. 

This type of water pump is to be used in the following circumstances:

• For home-based water supply like wells.
• To increase the pressure from the intake line.
• To pump water supply in places where no suction lift is needed.
• To move the water in a closed system
• To provide pressure source when it comes to fire protection systems.

Prior to buying a water pump, it is important to consider a few important factors such as the motor type, power, head and material. It is essential to know the horsepower of the pump and the total head discharge. As for the motor type and material, you can choose a gas, diesel, hydraulic or manual powered water pump, and make sure their material is resistant to water.
