6" Trash Pump
Description
This trash pump is heavy duty, centrifugal, engine driven, self-priming (to 20 ft. lift), and transportable unit. Pump is equipped with precision lapped mechanical shaft
seal to reduce the likelihood of leakage, and a clog resistant impeller capable of handling solids up to 3" in spherical diameter. Units are used to handle water
containing stones, sticks, mud, and other solids (up to 20% by volume). O-ring sealed flange connection to provide leak-free low maintenance operation. Suction
flange male NPT threaded for direct coupling to a standard NPS hose connector with rubber gasket. Liquid temperature range is 40º to 180º F (4º to 82º C). Maximum
casing pressure if used in a flooded suction application is 50 psi. For use with nonflammable liquids that are compatible with pump component materials.
All models come equipped with a 12V electric
starting system (battery not included). A fully
plumbed and mounted 12 gallon marine grade
plastic fuel tank is standard. All units equipped
with a digital tachometer/hour meter.
Pump and engine are mounted on an easy
maintenance sliding frame assembly. Frame
can be mounted to transport trailer equipped
with pneumatic tires, lighting system, rear
stabilizer jacks, and 1-7/8" diameter ball mount
tongue hitch. Trailer meets DOT requirements
and is supplied with certificate of origin and VIN
number. Check state and local requirements to
register trailer/pump for highway towing.

Assembly
Tail light assembly installation:
1. Install driver side tail light assembly with
license plate holder to trailer frame rail with
2 carriage bolts and nuts provided.
2. Connect red wire (light) to yellow wire
(trailer) with wire nut, connect two black
wires (light) to yellow/brown wire (trailer)
with wire nut.
3. Install passenger side tail light assembly to
trailer frame rail with 2 carriage bolts and
nuts provided.
4. Connect red wire (light) to brown wire
(trailer) with wire nut, connect two black wire
(light) to green wire (trailer) with wire nut.
NOTE: Follow all recommendations in General
Operating Instruction and Maintenance Manual
provided with this pump. In addition, follow the
specific recommendations that follow:
Installation:
Trailer mounted pump:
To avoid trailer tipping, set
rear trailer stabilizer jacks
before removing trailer from vehicle hitch.
1. Always set trailer tongue stand and rear
trailer stabilizer jacks before unhooking
trailer hitch from vehicle tow ball.
2. Make sure pump and trailer are level and
trailer wheels are blocked to prevent
movement during operation.
Frame mounted pump:
3. Pump frame must be supported on a level
firm surface. Anchoring pump frame to
support surface is required to prevent
movement during operation. A vibration
dampening mounting system should be
employed. Allow sufficient clearance around
pump frame to perform routine maintenance.
All installations:
4. Suction line should be as short and direct as
possible, have a constant slope up to the
pump’s suction port, and line diameter must
match suction port diameter. If hose is used,
it must be non-collapsible.
5. Check condition of suction hose gaskets
before installation. Weak, worn, leaking
gaskets will allow an air lead at suction
connection. If suction connection leaks air,
the pump will not prime.
6. Supports must be used to carry the weight
of the suction and discharge lines. The
pump should not be used to support the
entire weight of the suction and discharge
lines. Damage/breakage of pump ports may
occur if lines are not supported.
7. If a check valve or collapsible hose is used
on discharge, a means of venting air from
the pump discharge manifold is required
during the priming cycle. If air cannot
escape from casing, the pump will not prime.
LIFTING EYES
Pump frame is equipped with four 3/8-16x1" ID
lifting eye bolts (Ref. No. A6). Eye bolts
provided for lifting of pump frame on and off of
transport trailer and to lift complete pump/trailer
assembly. Eye bolts rates for lifting pump,frame
