How vacuum pumps work
Powered by your vehicle’s engine – via the hydraulic system – the septic truck vacuum pump creates a vacuum in the vessel, which then:
- Draws waste from septic tanks and other vessels (like grease traps) into the vessel fitted to the vacuum truck, and then
- Allows the waste to be safely transported to a treatment facility for disposal.
The pump usually has the capacity to handle large volumes of air flow. This is what creates the vacuum needed to handle all the different types of liquid waste.
Most systems also have additional shut-off valves and filters to prevent contaminants from entering the vacuum pump and causing damage.
All septic truck vacuum pumps create negative air pressure to draw waste into the tank. Each type achieves this in a different way:
- "Rotary vane" pumps use a set of spinning vanes attached to a rotor
- “Liquid ring” pumps use liquid under centrifugal force
- “Blower” pumps use twin high-speed, timed rotors
