OVERBOARD DISCHARGE PUMP

(MACERATOR)
Theory- If installed, the overboard discharge pump
(macerator)) can be used to pump out the holding tank in
international waters. The overboard discharge pump uti-
lizes an impeller type pump which grinds up the waste and
passes the waste to a seacock located on the vessel bottom.

TYPICAL OVERBOARD DISCHARGE PUMP
There is a special interlock valve which works with the
overboard discharge pump (macerator). This interlock
valve is normally in the "closed" position when the mac-
erator pump is off. The interlock valve features two sen-
sors which react to a magnet imbedded in the underside
of the handle. When the system is triggered power travels
from the monitor panel "push" button switch to the valve
which is opened and at that point activates the macerator.
What makes the interlock valve such a unique feature is
that the skipper does not need to manually open and close
a seacock in the bilge each time the overboard discharge
system is used.
The macerator system is protected by a 10 amp breaker
located at the ship's main DC distribution panel. For ex-
tended cruising it is recommended to carry extra macerator
pump impeller.
