What’s Involved in a Vacuum Truck?

When looking for the best vacuum truck on the market it is very important to consider its usefulness. You can fail to succeed in this area if you choose a truck that does only a mediocre job in handling demanding and important projects. Having very little knowledge can be risky, as that can result in purchasing a vehicle that is either not powerful enough or too powerful, both of which can lead to greater costs or even the potential of losing jobs over a long period of time. Below are some important tips on how to choose the most useful vacuum truck to fulfill the intended business needs.

Centrifugal or Positive Displacement

Vacuum pumps are considered a very crucial component of these trucks and a very important factor to consider before purchasing one. The more powerful and efficient the pump, the faster the task will be accomplished. There are 2 more common types of these available on the market today - positive displacements (PD) and centrifugal ones. A PD machine is a popular choice. There are 2 classifications of a PD pump, namely a reciprocating type and a rotary vane type with a very slight difference between them. Around 70% of the vacuum trucks in operation at different work stations are comprised of the positive displacements type of pump. This pump works properly underwater and can provide a constant flow even with low pressure.

A centrifugal pump can suck up objects weighing up to 66 pounds with a length of up to 10 inches diameter. It can suction rocks, water, soil and other debris.


Whichever pump you pick, it is also important to know that machine size does matter. It is also important to take into consideration the weight and size of the material that is being vacuumed.


To determine the amount of horsepower required for a truck, the buyer must be certain about the job that will be done regularly.

The above tips can be very useful when considering certain aspects about a vacuum truck, including the tank chassis, size and other components. It is important to choose the right type of truck to suit the specific requirements of each company so all tasks can be in an effective way and productively!
