The Lavac pump is actually a Henderson manual diaphragm bilge pump...and
should be maintained (lubricated/rebuilt) the same way as any other
manual diaphragm bilge or holding tank overboard discharge pumps.

They do need periodic lubrication...and synthetic Teflon or similar
non-petroleum water soluble grease is recommended.


Hmm. Since I'm just now rebuilding a Henderson Mk5 bilge pump, what gets
lubricated? Only thing I could see is the external lever that actuates the
diaphragm.


I'd put a good coating of Teflon or silicon grease on all the rubber
parts once a year to keep them soft and supple...it'll extend their life
and contribute to smoother operation. Also wherever moving parts move
against each other. Same grease is also good for y-valves and seacocks.
