A Series pumps are not as susceptible to cavitation compared to flat plate design because the flow path through the pump is an axial flow. This allows the velocity through the pump to be unchanged and carries the air out effortlessly.
It is not unusual for these pumps to run 24/7 operation for years without maintenance.
A Series pumps are vibration-free and environmentally friendly with no oil used for lubrication, and no oil discharged to atmosphere.
Complete, self-contained systems including liquid recovery and recirculation are available.
