There are many used pumper trucks for sale available from used pumper trucks dealers, giving many vacuum truck services an affordable option to increase their fleets. When purchasing a used unit from a pumper trucks supplier, it is important to determine if it has everything you need or if some important accessory should be installed. The need to maintain the motor, transmission, and other essential systems is obvious; however, for these specialty vehicles it is vital to have the vacuum tank in good shape. Without the right protection including being sure that the tank is equipped with the right pump and parts, this vital part of the unit will not reach its service life expectancy.
The Relationship Between Tanks and Pumps
A vacuum truck tank is more than just a physical tank; it includes pumps and valves that allow the tank to be as useful as it should be. All parts work as a cohesive unit to allow it to either suction or pump. There is an appropriate pump and accessory set-up for every vacuum tank; if it is not installed, damage to the pumps and even the tank itself, could occur. Repair of a damaged tank is a costly and labor-intensive, even for a pumper trucks supplier. The possibility of damage to the tank must always be considered before running the pump.
How Does Damage to Vacuum Truck Tanks Happen?
There are two main ways in which a vacuum truck tank can be damaged due to incorrect use. Use of pumps that are too powerful or that are not correctly adjusted or vented can lead to tank implosion if the outward vacuum pressure is too high, or tank explosion if the inward vacuum pressure is too high.
Preventing these conditions depends on any new or used pumper trucks having a few necessary gauges and valves we well as the right size pump that has been made for the tank volume in order to have the right amount of pressure. These accessories on a tank are essential, since they provide an important measure of operator control, enabling any necessary intervention to protect the tank and pump.
What Are Some Essential Tank Protection Accessories?
Companies that sell the best new and used pumper trucks know vacuum tank protection is imperative to prevent implosion or explosion. This protection is done through a variety of valves that offer increased control of interior tank conditions as follows:
-
Pressure and Vacuum Gauge – This gauge allows an operator to know the pressure or vacuum level inside the tank, independent of the actual gauges, to ensure everything is working properly.
-
Vacuum Relief Valve – This valve protects the tank from implosion by opening and allowing air into the tank once the vacuum begins to exceed a certain point.
-
Pressure Relief Valve – This valve protects the tank from explosion by opening and letting air out of the tank once the interior pressure begins to exceed a certain point.
Additionally, vacuum trucks require a pump that is specifically sized for the volume of the tank, since the safest and most effective use of the pump is the basis of good vacuum tank operation.
Many used pumper trucks come with various accessories directly from the pumper trucks supplier; however, for those that do not, installing later is not difficult. This should be a top priority for anyone purchasing new or used pumper trucks. Although these gauges are an extra investment, they are critical for the continued use and protection of every vacuum truck tank as well as operator safety. An experienced used pumper trucks company will be aware of this and can help buyers get the best truck for their money – one with all the necessary equipment and the longest possible service life!
