V70 turbo Pump replacement

Question

Hello there! 
 I'm looking for a replacement of varian v70 pump. will any existing agilent pumps work with the varian v70 controller?

Those functions are the same. 
 The real issue is the Agilent turbo and controllers are matched (tuned), and need to be paired together. 
 The V70 controller is designed to run the V70 turbo, and the 74FS controller(s) are designed for the 74FS turbo. 
 The full speed frequencies of these pumps are not the same (V70 - 1250HZ // 74FS 1167HZ). 
 
 Using the incorrect turbo controller can damage the pump by ramping and spinning it at resonant speeds that can jeopardize the mechanical integrity (bearing damage). 
 In some cases, catastrophically.

The Agilent V74 turbo pump can replace the V70 turbo pump. The v70 controller will only run the v70 turbo pump. The V74 datasheet provides the turbo and matched controller specifications.
