MMI's new flexible impeller pump is interchangeable with the early gear type pumps, as well as any of the later OEM flexible impeller pumps used by Universal.
The shaft is retained between two packless ball bearings, which eliminates the need for the small snap ring on the outside of the impeller to prevent the shaft from floating. The grease cup has also been eliminated by the packless bearings.
The pump includes an MMI Quick-Change back plate to facilitate on-boat replacement of the impeller. The Quick-Change back plate is designed with an o-ring and 4 captive thumb screws. The captive feature of the thumb screws prevents them from being dropped into the bilge when removing or replacing the cover.
This pump has been designed to use the same shaft lip seal as Jabsco and Oberdorfer models, and the impeller is the same as those used in the Oberdorfer 202 and 201 series pumps.
