If you need a substance removed via the use of a suction pump of some kind, it may be worth looking at used vacuum trucks. These are trucks especially designed to hold a storage container and a suction motor and can be used to pump anything from contaminated soil to residential housing septic tanks. Often, vacuum trucks will be classified and categorized based on their weight and capacity, as well as whether they are used to pump dry or wet materials.
It should be noted that if you need to pump liquids, you will need a different pump than one used to pump solid materials. The pumping trucks used in vacuum trucks usually have a diameter of 1 to 4 inches, though this will also depend on the specifics of a particular job.
A vacuum truck’s pump can be operated either by a dedicated motor or via a PTO or power take-off using the vehicle’s engine. Power take-offs normally consist of a splined drive shaft connected the vehicle’s drive train. Power can be cut from the wheels when the truck is stationary and directed instead into the take-off unit. With the drive shaft and take off in place, it can be used to power various tools and items, including the example featured in this article – a vacuum truck’s pump. A vacuum truck may use either hydraulics or a belt to drive the pump.
Although most vacuum trucks are purpose built for that primary function, vacuum units can also be attached and mounted onto a pick-up truck’s bed or a trailer. In this situation, it is not possible to use PTO to power the pump. Instead, a small gasoline engine is normally used to provide the pump with the necessary power. This setup is often known in the industry as a pony motor.
There is usually some sort of boom attached to the vacuum pump to enable it to actual pump the substance that needs to be removed. The boom is attached securely to the tube of the pump allowing easier maneuverability when it has to be positioned over materials that need to be removed.
