First called a 4x35 and a 2x35, the MDX Series were the first centrifugal
pumps manufactured by MARCH in the late 50's. Subsequently the nomenclature
was changed to reflect the magnetic drive principal.
The MDX Series pumps, since their inception, have undergone numerous
improvements. The basic design, however, remains the same.
As indicated in the options and specifications that follow, variations in
the MDX Series include: numerous inlet and discharge ports, several motor
options and wetted material combinations for total chemical comparability.
The MDX Series can and should be classified as "the granddaddy of them all".
