INSTALLATION INSTRUCTIONS

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
1600 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 3-6.

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 oil or a synthetic oil such as

Mobil 1 (15W-50).

3. Acids, alkalines, or abrasive fluids cannot be
pumped unless approval in writing is obtained

Crankcase oil should be changed after the

before operation from Giant Industries, Inc.
first 50 hours of operation, then at regular
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.

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.

REPAIR INSTRUCTIONS - P200A SERIES

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. With 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.
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.

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 (23)
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!

12

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.

REPAIR INSTRUCTIONS - P200A SERIES

9. If the ceramic plunger pipe
(16B) is damaged, remove
