When looking for good vac trucks for sale, a company must consider that a vac truck purchased today is somewhat different than when these units were first introduced. Over the years, pumping and septic trucks have improved in design and function, making their jobs easier and more efficient. There are many makes and models of used and reconditioned vac trucks available for sale. Any of these units should work well for a company in need of affordable units to add to their fleet. To get the best from used trucks, a company must understand older technology and know exactly what they are – and are not – getting.

What Has Stayed The Same?

Vacuum trucks have seen significant changes in the past few decades. So much has changed that it is easier to discuss what has stayed the same, than what has changed. One thing that has remained nearly the same is the tank itself because essentially, a vac truck is a rolling tanker. Although aluminum is more in demand and tank sizes have increased substantially, tank material and design have varied little throughout the years. On the other hand, the rest of the truck has seen significant changes.

Vacuum Pump Technology

The first vac trucks for sale used diaphragm pumps that built up vacuum suction by keeping the truck engine running. Although this worked, it was not efficient by any means. Trucks had to run constantly to retain the vacuum.  I there was even the slightest leak in the system, nothing worked. This put a lot of strain on truck engines, requiring frequent valve jobs. It also created a lot of pollution.

The introduction of the rotary vane pump, which drew its power from a PTO rather than the engine, revolutionized vacuum trucks. The rotary vane pump is still used today since it creates cleaner, stronger and more efficient vacuum power. Over time, these pumps have become bigger and stronger. Modern vac trucks are much faster and more efficient than those that operate with older technology.

Truck Chassis and Engine Improvements

As pumps have become larger and stronger with greater output, tanks have increased in size to match that output. With a larger tank, the truck chassis has increased in size as well, along with the engines, to account for increased weight and volume. Smaller trucks with smaller tanks are still available; however, the average truck and tank size has continued to increase with the availability of stronger pumps.

Truck Amenities and Equipment

More buyers are purchasing things that both increase overall function and are more operator friendly. Companies want vac trucks for sale that offer better, more reliable automatic transmissions as well as more on-board, ergonomic comforts to increase safety and driver comfort – which helps retain experienced employees.

Many vacuum trucks also carry more than just a tank and pump. Jetters are added to increase services offered to customers. Safety equipment, like alarms and backup cameras, is also added. Today’s units do more than suction septic waste, with more manufacturers building trucks that offer more functionality as a result.

Other significant changes that vac trucks have seen over the years is a substantial increase in cost, which probably comes as no surprise. Better technology and equipment costs more, which makes used and reconditioned units worth more to those seeking an affordable option. Thankfully, vacuum truck dealers can usually find units that fit most budgets. While they may not have all the latest bells and whistles, most companies will still find a truck that works well for them!
