To the best of my knowledge, a compatible pump was not fitted to any other engine.
The SD22 was fitted to the Datsun/Nissan model 720 pickup (truck, lorry) in many parts of the world (1981-2), and what is probably the same pump was used on the SD23 and SD25 (720 pickup, 1983-1986.5).
The SD engines began production in approximately 1963, up through at least the late 1980s. They were used in agricultural applications (water pumps for farming), forklifts (fork trucks), and small marine applications (auxiliary engines for small boats). It was a very popular engine.
Is it possible to get a new pump in the US?
Yes! They are widely available in the US. For example, here is one from NAPA, a large automotive parts distributor in the US:
NAPA NWP559198, US$67
