Vanes transfer mechanical energy from the pump shaft to the fluid by creating centrifugal force, which increases fluid pressure and velocity for efficient pumping.
In dry pumps, vanes are often made from self-lubricating materials like carbon graphite to minimize friction, while wet pumps use corrosion-resistant materials like stainless steel and rely on fluid for lubrication.
Regular inspection for wear, clearance checks, and replacement when thickness reduces beyond tolerance; lubrication if applicable; and cleaning to prevent buildup that affects balance.
