edwards pump

[andcia]

Hello

we need to replace an old pump Edwards 1.5 E2M1.5 part n. A37124919
i've found an Edwards 1.5 E2M1.5 at good price with same characteristics of the previous but different part number A37132919

someone knows the difference between the two models

(the old is marked agilent the other not.... someone knows if there is a substantial difference between the two pumps?)

Thanks

Difference could be as simple as different connections; I'd contact Edwards.
