A vane pump or rotary blower for wastewater vacuum trucks? It’s a question I have been toying around with for some time. There are appropriate uses and situations for each vacuum technology, but before I share my suction strategies, I should explain in detail how each machine works.
A vane pump compresses air to create a void where vacuum is created. Depending on the model, it will take anywhere from 45 seconds to 2 minutes to build up vacuum to start working. A rotary blower displaces air to create that vacuum, creating negative pressure in seconds, and the technician is ready
