Periodic maintenance and inspection is required on all pumps to ensure proper operation. Unit must be clear of debris and sediment. Inspect for leaks and loose bolts. Failure
to do so voids warranty.
3-Inch Premium Trash Pumps
Refer to pump manual 1808-633-00 for General Operating and Safety Instructions.
DESCRIPTION
These trash pumps are high capacity, heavy duty, centrifugal, engine driven, self-priming (to 20 ft. lift), portable units. The pumps are equipped with a
precision lapped mechanical seal to reduce leakage, carrying handle, and a clog-resistant impeller capable of handling solids up to 1½" diameter.
Engine shaft on all models is sealed from liquid and protected by a stainless steel shaft sleeve. 3" NPT suction strainer is included. Units are designed to
handle water containing mud, sand, sludge, solids and sewage (up to 25% by volume). Handles liquids from 40º to 180º (4º to 82º C). For use with
nonflammable liquids compatible with pump component materials.
MAINTENANCE
Always disconnect battery cables and spark plug wire from spark
plug before performing any maintenance operation requiring
disassembly of the pump.
CLEANING
This unit is designed so that for most cleanout or clogging problems, it
should not be necessary to remove hoses or piping. Discharge area
and manifold (Ref. No. 12) can be reached by opening top cleanout
cover plate (Ref. No. 14). Clear all debris from inside manifold and
from strainer portion of manifold gasket (Ref. No. 8). Suction area and
impeller chamber can be reached by removing suction cleanout cover
plate (Ref. No. 3). This plate is locked in position with four threaded
handles. Next to two holes thru which these handles pass in locking
position there are tapped holes. To remove cover plate, first remove
four threaded handles. Then thread two thread handles into an
opposite pair of tapped holes. This will serve as a jack to pull cover out
of casing.
NOTE: When replacing either cleanout cover plates, be sure O-ring
sealing gaskets are in position. Carefully wipe all surfaces on which O-
rings have contact. It will facilitate removal and replacement of suction
cover plate (Ref. No. 3) if a thin coating of grease is wiped over O-ring
gasket (Ref. No. 7).
REPAIRS & REPLACEMENTS
NOTE:
First examine exploded parts illustration which shows all parts
and how they are related to one another. Different degrees of
dismantling can be accomplished depending on what areas of pump
are to be reached. Note that engine front pump assembly can be
removed by first removing (6) fasteners (Ref. No. 9) from adapter (Ref.
No. 35). Impeller and cutwater/wearplates are subject to wear only by
abrasive action of sandy or dirty fluid. If badly worn, all these parts can
be replaced easily and pump thus restored to full efficiency.
IMPELLER (REF. 23) & WEARPLATE (Ref. 26)
RENEWAL
When clearance between impeller and cutwater/wearplate exceeds
1/16" at face of impeller or 1/8" on outside diameter of impeller, it may
be necessary to take corrective action. Increased clearance can cause
lengthened priming times and reduced pumping capacity. If both
priming and capacity of your unit are satisfactory for your application, it
is recommended that no corrective maintenance be performed
regardless of what clearances may have developed, since increased
clearances in themselves are not generally dangerous to your pump.
Normally, new pump face clearances can be restored by simply
shimming behind the impeller. (Add shim washers Ref. No. 38). If
diameter of impeller is badly worn or if 1/16" shim washers do not
restore clearances to less than 1/16" face dimension and/or 1/8"
diametral clearance, it is recommended that impeller be replaced. This
is usually all that is required since only on unusually abrasive surfaces
do cast iron wearplates show deterioration.
REMOVING FRONT WEARPLATE (REF. NO. 5)
Remove suction cleanout cover (Ref. No. 3) using handles (Ref. No. 1)
as jack-screws as described under Cleaning. Front wearplate is
attached to cover with three 5/16" socket head cap screws (Ref. No.
6). Remove these screws and replace wearplates. Be sure mating
surfaces are wiped clean of all dirt.
TO REMOVE CUTWATER/WEARPLATE (REF. 26)
Remove front pump assembly by removing six fasteners (Ref. No. 9)
that hold casing (Ref. No. 21) to adapter (Ref. No. 35) and fasteners
(Ref. Nos. 42 & 33). Remove impeller (Ref. No. 23) by unscrewing
(right hand thread) it from shaft. Cutwater/wear plate can then be
removed by removing socket head screws (Ref. No. 25) that hold it to
adapter (Ref. No. 35).
REMOVING SEAL (REF. NO. 36)
1. Remove pump casing (Ref. No. 21) and impeller (Ref. No.
23) as described under "To Remove Cutwater/Wearplate"
above.
