APLICATIONS
WASTE EVACUATION
The Jabsco 18590 series DC macerator pump unit is the ideal solu-
tion for emptying marine holding tanks when not in a discharge
restricted area. Self priming to 5ft this pump will empty a typical
30 gallon (115 Liter) holding tank in less than 3 minutes. Duty
cycle of the pump is 15 minutes continuous which means a 180
gallon (680 liter) can be emptied in a single operation.
It is recommended that holding tanks be flushed with several gal-
lons of water after each pump out. This will reduce the possibility
of a continued build up of sediment in the tank which could cause
a potential blockage.
FISH BOX AND LIVEWELL TANK EVACUATION
The Jabsco Macerator Pump is the ideal pump for the emptying
of Fish box and livewell receptacles. Very often the livewell tank
will be above the waterline of the boat, when this is the case
gravity can be used to empty the livewell tank. If not installed in
this format then it is beneficial to use the Jabsco macerator pump
for evacuation due to its self-priming capabilities and also it's
grinding properties.
Fish boxes are typically mounted into the floor of the vessel and
are very often below the waterline or only partially above the wa-
terline. Again the Jabsco Macerator pump has the characteristics
that lend themselves to this application. The bait residue particles
of ice, fish scales and anything else that could potentially be found
in the Fish-Box will be easily passed buy the Jabsco Macerator
Pump, and the self priming capabilities are perfect for fish box
installations common to many of today's sports fishing boats.
GENERAL INSTALLATION SUGGESTIONS
The pump can be mounted in any orientation without loss of
performance. It is however recommended that if the pump is
mounted vertically then the pump head be mounted below the
motor (pump head facing downwards).
Use the rubber grommets provided to absorb vibration.
The Macerator pump can be screwed directly into a 1-1/2" (38mm)
NPT tank flange or female pipe fitting. If attaching the inlet port to
a pipe fitting it may require removal of the hose barbed port, this
