dynamic pumps-magnetic pumps
Magnetic drive pumps use magnets to generate movement. These magnets are mounted on a carrier or drive assembly and are driven by a standard electric motor. For dynamic pumps, this drive assembly typically moves an impeller; for positive displacement pumps, it moves a mechanism which expands and contracts a cavity. The drive assembly consists of two separate rings of permanent magnets. The outer set moves the inner set via a rotating magnetic field, which in turn drives the pumping mechanism.
Most Magnetic drive pumps are centrifugal pumps (a subset of dynamic pumps), although there are also positive displacement magnetic drive pumps (like the gear pump pictured above). Centrifugal pumps utilize one or more impellers to generate fluid velocity.
