This pump impeller Ref. 110 is a flexible replacement impeller for cooling water and seawater pumps on inboard engines, generator sets, and other marine installations. The impeller has 6 blades and profile number 7 and is intended for pumps where the dimensions, hub design, and profile match the existing impeller.
The impeller has an outer diameter of 50.8 mm and a width of 22.1 mm. The hub dimension Ø A is stated as 7.31 / 8 mm for the inner and outer measurements respectively, and the shaft hole has one flat side. The impeller is supplied as a loose spare part without specified gaskets or other mounting components.
The spare part cross-references to Jabsco 7273-0001 and Ancor 2745. Jabsco 7273-0001 is used, among others, in Jabsco pumps from the 18610, 28140, and 53020 series. The specific pump and installation should always be checked before replacement.
There are conflicting cross-references for impellers with these dimensions. Oberdorfer 6617, Jabsco 6303-0001, and Johnson 09-824P appear in several spare parts catalogs along with Jabsco 7273-0001, but Jabsco data shows that 7273-0001 and 6303-0001 have different impeller profiles. These numbers should therefore not be used as unambiguous cross-references for this Ref. 110 variant. Always check the diameter, width, hub dimension, number of blades, and profile rather than just comparing nominal dimensions or cross-reference numbers.
