Installation of the Giant Industries, Inc.,
pump is not a complicated procedure, but
there are some basic steps common to all
pumps. The following information is to be
considered as a general outline for installation. If you have unique requirements, please
contact Giant Industries, Inc. or your local
distributor for assistance.
1. The pump should be installed flat on a base to
a maximum of a 15 degree angle of inclination
to ensure optimum lubrication.
2. The inlet to the pump should be sized for the
flow rate of the pump with no unnecessary
restrictions that can cause cavitation. Teflon
tape should be used to seal all joints. If pumps
are to be operated at temperatures in excess of
0
160
F, it is important to insure a positive head
to the pump to prevent cavitation.
3. The discharge plumbing from the pump
should be properly sized to the flow rate to
prevent line pressure loss to the work area. It is
essential to provide a safety bypass valve
between the pump and the work area to protect
the pump from pressure spikes in the event of a
blockage or the use of a shut-off gun.
4. Use of a dampener is necessary to minimize
pulsation at drive elements, plumbing, connections, and other system areas. The use of a
dampener with Giant Industries, Inc. pumps is
optional, although recommended by Giant
Industries, Inc. to further reduce system pulsation. Dampeners can also reduce the severity of
pressure spikes that occur in systems using a
shut-off gun. A dampener must be positioned
downstream from the unloader.
5. Crankshaft rotation on Giant Industries, Inc.
pumps should be made in the direction designated by the arrows on the pump crankcase.
Reverse rotation may be safely achieved by
following a few guidelines available upon
request from Giant Industries, Inc. Required
horsepower for system operation can be obtained from the charts on pages 3-9.
6. Before beginning operation of your pumping
system, remember: Check that the crankcase
and seal areas have been properly lubricated per
recommended schedules. Do not run the pump
dry for extended periods of time. Cavitation will
result in severe damage. Always remember to
check that all plumbing valves are open and that
pumped media can flow freely to the inlet of the
pump.
Finally, remember that high pressure operation in a pump system has many advantages. But, if it is used
carelessly and without regard to its potential hazard, it can cause serious injury.
IMPORTANT OPERATING CONDITIONS
Failure to comply with any of these conditions invalidates the warranty.
1. Prior to initial operation, add oil to the
crankcase so that oil level is between the two
lines on the oil dipstick. DO NOT OVERFILL.
2. Pump operation must not exceed rated
pressure, volume, or RPM.
A pressure relief
device must be installed in the discharge of
the system.
Use Giant 20W-50 oil (p/n 01153)
3. Acids, alkalines, or abrasive fluids cannot be
Crankcase oil should be changed after the
first 50 hours of operation, then at regular
pumped unless approval in writing is obtained
before operation from Giant Industries, Inc.
intervals of 500 hours or less depending on
operating conditions.
4. Run the pump dry approximately 10 seconds
to drain the water before exposure to freezing
temperatures.
Consult the factory for special requirements that must be met if the pump is
to operate beyond one or more of the limits specified above.
NOTE:
In order to drive the pump from the side opposite the present shaft extension, simply
remove the valve casing from the crankcase and rotate the pumps 180 degrees to the
desired position. Be certain to rotate the seal case (item #20) as well, so that the weep
holes are down at the six o'clock position. Exchange the oil fill and the oil drain plugs,
also. Refer to the repair instructions as necessary for the proper assembly sequence.

NOTE: Always take time to lubricate all metal and nonmetal parts with a light film of oil before reassembly.
This step will ensure proper fit, at the same time protecting the pump nonmetal parts (i.e., the elastomers) from cutting
and scoring.
1.W ith a 22mm socket
wrench, remove the (3)
discharge valve plugs and
(3) inlet valve plugs (32)
Inspect the o-ring (33) for
wear and replace if
damaged.
4.Remove the o-ring (31).
Inspect all parts for wear
and replace as necessary.
Apply one drop of Loctite
243 to the valve plugs (32)
and tighten to 59 ft.-lbs.
2.Using a needle nose pliers,
remove the inlet and
discharge valve assemblies
(32X).
5.Next, use a 5mm allen
wrench to remove the 8
socket head cap screws
(34).
3.By inserting a small screw
driver between the valve
seat (27) and the valve
spring retainer (30), the
valve assembly can be
separated.
6.Carefully slide the valve
casing (26) out over the
plungers.
7.Remove the weep return
ring (25), pressure ring
(24), and v-sleeve (23)
from the valve casing (26).
Remove the v-sleeve
(23A) from the seal case
(20). Inspect all parts,
including o-ring (21) for
wear and replace as
necessary
8.Check surfaces of plunger
(16). A damaged surface
will cause accelerated
wear on the seals. Deposits of any kind must be
carefully removed from
the plunger surface. A
damaged plunger must be
replaced!
10
9.If the crankcase oil seals
(19) are to be replaced,
they can be removed by
prying loose with a flat
screwdriver. Take care
not to make contact with
the plunger.
10. If the ceramic plunger pipe
(16B) is damaged, remove
the plunger bolt (16C).
Discard the old plunger
pipe (16B) and copper
gasket (16D), and clean the
old locktite from the
plunger bolt (16C) and
plunger base (16A).
Replace the plunger with
the new one and locktite
the plunger bolt and torque
to 220 inch-pounds.
NOTE: If there are
deposits of any kind (i.e.,
lime deposits) in the valve
casing, be certain that the
weep holes in the weep
return ring (25) and valve
casing (26) have not been
plugged.
Reassembly sequence of the P217/P218/P219/P220/P221/P227/P230
pumps
1)If oil seals (19) were removed, replace with seal lip towards crankcase. Lubricate seals before
replacing.
2)Replace seal case (20) with o-rings (21) over plungers. Generously lubricate o-rings and oil
seal before reassembly. Replace v-sleeve (23A) over plungers (16)..
semble weep return ring (25) and pressure ring (24) over plungers (16). Slide valve casing over
plungers and seat firmly. Replace the eight socket head cap screws (34) and tighten to 105
inch-pounds in a crossing pattern.
4)Replace the six o-rings (31) and the six valve assemblies (32X). Now replace the six valve
plug o-rings
( 33). For pumps manufactured prior to 5/97, tighten plugs (32) to 33 ft-lbs. otherwise, apply one drop
of Loctite 243 to the valve plugs (32) and tighten to 59 ft.-lbs.
