APPLICATION

The Flojet 18555-000 DC portable waste pump is the
ideal solution for emptying holding tanks on recreational
vehicles and avoiding dump stations. The macerator
section grinds waste down to a particle size of
1/8" maximum so it can easily be pumped through a
garden hose. Empties a typical 40-gallon holding tank in
less than 5 minutes. Do not run more than 15

minutes continuously.

The 18555-series waste pump will macerate and pump
all waste and tissue normally found in recreational
vehicle waste systems. IT WILL NOT HANDLE HARD
SOLID OBJECTS, SANITARY NAPKINS OR RAGS.

RECOMMENDED HOSE TABLE

Hose Size Maximum Hose Length

5/8” (16 mm) 25 feet (7.5m) max
3/4” (19 mm) 50 feet (15m) max

Recommended lengths are based on horizontal
discharge. Longer discharge runs create higher
resistance and may result in the pump motor over
heating.

DO NOT MOUNT PERMANENTLY
TO THE RV WASTE PORT.

DISASSEMBLY

Remove the four acorn nuts 3/8” (10 mm) (Key 1) and
fiber washers (Key 2) from the pump studs (Key 3). Slide
the macerator adapter (Key 4) off the studs. Insert a thin
bladed 9/32" (7mm) ignition wrench behind the chopper
plate (Key 6) and onto the flat of the motor shaft to
prevent it from turning. Unscrew (counter-clockwise) the
locknut 7/16” (11 mm) on the end of the motor shaft and
remove the stainless steel chopper blade.†Remove the
pump wearplate (Key 7) and two paper gaskets (Key 8).
Now slide the pump body (Key 12) with impeller (Key 9),
small wearplate (Key 10), two studs and shaft seal as an
assembly off the motor shaft and remaining two
mounting studs. Remove the starlock retaining washer
on the seal and push the seal out of the seal bore.

If reconditioning pump with a service kit (Part No.
18598-1000), it is not necessary to remove the seal
because the new seal is pre-installed in the new body. It
is also generally not necessary to remove the slinger or
brass studs screwed into the motor end bell.

ASSEMBLY

If installing a new seal, push it into the seal bore of the
body with the lip pointing toward the impeller bore.
Press the starlock washer into the seal bore with the
concave side up to secure the seal in the bore. Install the
two shorter studs in the two holes with threaded inserts
in the new pump body and tighten finger tight. If
required, screw the two longer studs into the tapped
holes in the motor end bell. Slide the new pump body
with the shaft seal installed onto the motor shaft and two
long mounting studs in the motor. Slide the small
wearplate over the motor shaft and position it in the
bottom of the impeller bore. Slide the new impeller onto
the motor shaft and, with a counter-clockwise motion,
push it into the pump impeller bore. Position one new
