Seeking specific data for a National Oilwell A-346 Triplex Pump...

[SNORGY]

...and suppliers / OEMs have as yet not been able to provide these data.

Specifically, what I am looking for is:

(1) connecting rod length
(2) NPSHR for 3.75" plungers, 6" stroke, 307 rpm

Can anyone point me towards a source or old catalogue data? Otherwise I can make some assumptions that will allow me to get by...but it's nice to have the actual hard data.

Thanks in advance...

Regards,

SNORGY.

Thanks all, but I received a call and confirmation from a supplier answering my questions.
