Parker Vacumatic Diaphragm Size?

[adyf]

Would the below vacumatic deskpen require a deb sized diaphragm or a standard?

according to the Pensac Co website, all speedlines use deb size diaphragms

I should pin this.....

 

All debutante, 51, 2nd generation Major and Junior pens use the Deb size sac.

 

The 1st generation Jr, 3 band standard and the Maxima use the standard size.

 

Only the Oversize pens use the Oversize diaphragm.

 

Therefore, buy mostly deb diaphragms, a few standard, and a couple OS, if you think you might need them some day.

Ron, is was the speedline filler that made me wonder. Do lockdown fillers all use the same size diaphragm or were they fitted to different size pens and therefore use different size diaphragms?

OS lockdown fillers should use lockdown diaphragms. Major and jr lockdowns should use standard diaphragms

Sorry, I missed this while we were traveling last week.

 

All of the first generation pens had lockdown fillers, but the different models and size pens used different size diaphragms. There were some deb size pens, and they used a deb sac. The 2 band Jr and 3 band Standard used the standard diaphragm, and as Sean noted the OS used the OS diaphragm.

 

The pump tube itself is the same size for all pens in both lockdown and streamlined fillers. Just the cone and thread bushing size is different, so if you have a clean tube for one size, and need one for another size pen, you can pull the flat bar and swap out cones and bushings. A bit fiddly to do, but not difficult. Just don't lose the little bar that goes through the cone and the pump.

No worries Ron, thanks for your reply.
