Vacuum trucks are useful in a variety of applications which all do basically the same thing – suction and pump material in different forms. Before buying vehicles from any company offering septic trucks for sale, a business needs to understand the differences in the various types of vacuum pumps and blowers to determine which is most appropriate for their use. Companies who offer the best oil and gas septic trucks for sale typically have a wide selection of trucks; narrowing down that choice depends on choosing the right pump for the job.
Pump or Blower – How Do They Differ?
Those who provide oilfield and other types of septic trucks explain that pumps or blowers differ based on how the vacuum truck will be used. Each has its advantages; however, depending on the job, one may be more suitable and more efficient in keeping operations running smoothly:
-
Rotary Vane Pumps – These type of pumps function by creating pressure inside the tank through air compression which sucks material up the hose and into the tank when the hose and gate is open.
-
Positive Displacement Blowers – These blowers displace air inside the tank with twin rotors that suction material up the hose and into the tank as air is being displaced.
Pumps and blowers do basically the same thing: remove air from inside the vacuum tank and suction material up the hose into that space; how they accomplish this is where they differ. Businesses that offer the best septic trucks for sale note that these slight functional dissimilarities make a world of difference on the job, making each style of displacement beneficial in different applications. Hose size can also affect pump or blower performance; generally speaking, hoses should be used in standard sizes recommended by the pump or blower manufacturer based on the capacity of the unit.
Application Will Determine Pump Style
The biggest difference between rotary vane pumps and positive displacement blowers is the power each creates. Pumps handle jobs requiring less than 1,000 CFM for lighter or looser materials, such as septic waste, water, and less bulky material. For jobs involving material that is heavier, bulkier, or requires stronger suction power, such as the material found in hydroexcavation and oilfield work, the blower is likely a better choice. Providers that sell oilfield septic trucks typically suggest blowers for this reason, while standard septic trucks for sale are usually outfitted with pumps.
One Truck For Multiple Jobs?
Since vacuum trucks are so versatile, many companies use them for a wide variety of things depending on demand, the season, and other details. If the different jobs all require lower CFM, it is probably wasteful for a company to spend money on bigger, blower-driven units. Businesses offering the best septic trucks for sale suggest companies who perform heavier work as well as different, side applications would better spend their money on blowers, as the main concern of not having enough power would be removed from the equation. To achieve the greatest efficiency, buying the pump style that will be used the most is recommended.
Before deciding to add additional vacuum truck units to a work fleet, it is essential for buyers to determine actual usage needs, then select a vehicle with the right type of vacuum mechanism. When viewing the selections offered by a dealer offering oil and gas septic trucks for sale, or any type of general septic trucks for sale, the best choice is to narrow the list of possible choices by first determining which units have the appropriate pump or blower to meet *most* job needs – and continue on from there!
