Neovane pumps were made throughout the last half of the 20th century
by Hanly Manfacturing. Hanly retired around 1990 and the business was
not purchased or continued.
Several variations of the pumps were manufactured including belt driven, cam driven
some with integral outlet dividers, some without. Aftermarket companies
including Hallcraft and Nicson among others made water outlets
for the Neovane pumps. People frequently mistake the name on the aftermarket
dividers for the name of the pump. A Neovane pump frequently will have
a divider on it with the name Nicson or Hallcraft. Its still a Neovane pump.
Rex Marine frequently has used Neovane 3/4" pumps for sale. If looking for a good
used pump please check with us.
To replace the 392100 impeller remove the pump cover. If vanes are
missing off the impeller you need to find them. Typically they
break off and become lodged in fittings or oil coolers. These
broken off vanes can cause overheating even after a new impeller
is installed due to restricted water flow.
Drive the threaded pin out that passes through the impeller and shaft
with a small drift punch. Pull the old impeller off the shaft. Put a little light
grease on the shaft and the inside of the impeller cover. Drive the pin
back through the impeller and shaft so the ends of the pin are
just inside the impeller surface.
Getting the cover back on is much easier if you use a couple 1/8"
pins for line up in the holes provided in the casting. Slide the
cover over your pins and get a couple screws started. Tighten
the screws down in sequence a little at a time pulling the cover
down over the impeller. Take a screwdriver crosswise in the cam
drive and turn the pump while pressing down on the cover.
Suggested impeller change interval is 1-2 years maximum as rubber
