P.T.O. PUMP OPERATION INSTRUCTIONS PUMPING FROM HYDRANT
1. Position chassis near hydrant and set parking brake. Place truck transmission in neutral.
CAUTION: Make sure that truck transmission shift quadrant lock is used. Place wheel
chocks in front and behind tires.
2. Attach one end of the suction hose to the hydrant and the other end to the pump suction
connection. Be sure the inlet strainer is installed and all drain valves are closed.
3. Open hydrant valve slowly to avoid rush of water.
4. Maintain engine idle speed and engage power take-off device.
5. Open discharge valve on pump.
NOTE: It is not necessary to use primer when pumping from hydrant. Accelerate
engine and adjust discharge valves to obtain desired pressure and volume. Set relief
valve operating pressure per the specific instructions supplied elsewhere in this
manual.
6. When using soft suction hose between pump and hydrant, do not use nozzles of larger
capacity than the hydrant will supply.
PUMPING FROM BOOSTER TANK
1. Position chassis and set parking brake. Place truck transmission in neutral. CAUTION:
Make sure that truck transmission shift quadrant lock is used. Place wheel chocks in front
and behind tires.
2. Close all drain valves.
3. Open valve in supply line from booster tank to pump suction.
4. Maintain engine idle speed and engage power take-off device.
5. Pull out primer handle. When discharge gauge registers pressure, open discharge line, and
release primer handle.
6. Accelerate engine and adjust discharge valves to obtain desired pressure and volume.
CAUTION: Do not try to pump a large volume of water, as suction supply line from
the tank will not handle it.
7. Set relief valve operating pressure per the specific instructions supplied elsewhere in this
manual.
PUMPING FROM DRAFT
1. Position chassis as close to the water source as possible and set parking brake. Place
truck transmission in neutral.
CAUTION: Make sure that truck transmission shift quadrant lock is used. Place wheel
chocks in front and behind tires. The pump will exceed the rated capacity on a ten
foot vertical lift, however, as the lift increases, performance and capacity will
decrease.
2. Attach hard suction hose to the suction nipple on pump and attach the hose strainer to the
other end. Be sure suction hose gasket and inlet strainer are in place, and all drain valves
are closed.
3. For best results, submerge suction strainer two feet or more in the water and avoid
pumping large volumes from shallow water.
4. Maintain engine idle speed and engage power take-off device. Pull out primer handle.
CAUTION: Care must be exercised not to operate pump without water as this can
seriously damage pump.
5. When discharge gauge registers pressure, open discharge line and release primer handle.
6. Accelerate engine and adjust discharge valves to obtain desired pressure and volume.- Set
relief valve operating pressure per the specific instructions supplied elsewhere in this
manual.
WARNING BUTTERFLY STYLE SUCTION VALVES
NOTICE: The PSD pump incorporates a butterfly style valve in the suction side of the
pump, or pumps utilizing large diameter delivery hose, REQUIRE the use of a suction
side relief valve of sufficient size and MUST be set at 150 PSI MAXIMUM. Do not
hydrostatic pressure test the butterfly valve above 150 PSI and make sure that it is in
the open position.
Most brands of butterfly valves REQUIRE modification for use. If the butterfly valve is supplied
by anyone other than Hale then contact our Engineering Department for the latest retrofit
requirements. Failure to stay within the above parameters releases Hale Products Inc. from all
liability resulting from the misuse or improper installation of this product.
Many Centrifugal Pump Troubles are Due to Air Leaks
Procedure to follow to detect possible air leaks:
A. Start engine with pump disengaged and with pump drained.
B. Tightly close pump drain valve as well as booster tank suction and discharge valves (if
connected to a booster tank). Tighten caps on suction and discharge openings. Then pull
out primer handle.
C. Observe hand on vacuum gauge until it reaches a stationary position; this should be 20
inches or over.
D. Release primer handle and carefully watch vacuum gauge hand. If hand drops back rapidly,
it indicates a leak, which must be located and corrected. If it stands stationary, or moves
back very slowly, it indicates either no leak, or a minor leak, which will not interfere with
satisfactory operation.
E. Should test indicate a leak in pump proper, the stuffing box may need adjustment, if
equipped with packing. If the pump is equipped with a mechanical seal, it may require
service.
F. Now remove discharge cap. If vacuum gauge hand returns toward zero, more rapidly than
before cap was removed, it indicates that the self-closing poppet valve within the discharge
manifold is not properly seated and this condition should be corrected.
G. When difficulty is experienced in locating an air leak, it may be found by connecting pump
suction to a hydrant. With hydrant pressure on pump, look for water leaks, any one of
which indicates a possible air leak. When connected to a booster tank, there may be an air
leak in booster line valves - in valve proper, or around valve stem. The former may
necessitate replacement of complete valve while the latter may be corrected by replacing
valve stem.
H. Do not overlook possibility of air leaks in suction hose or couplings. To test for such leaks,
connect suction hose to pump suction, place pump suction cap over the end of the suction
hose, and test in the same manner as described above as to the motion of the vacuum
gauge hand.
I. It is a very good idea to make periodic tests for air leaks. NOTE: Excessive air leakage
may delay, or even prevent priming.
Trouble Shooting Guide
Pump Fails to Prime or Loses Prime
1. Restriction at the Suction Strainer
a. Remove all leaves, dirt and other foreign material from the strainer.
b. Use extra caution when drafting from shallow water sources with mud, sand or gravel
bottom.
c. Keep the strainer off bottom by placing it inside a barrel with the top cut down, or use a
similar method.
2. Suction Lift too High
a. Suction lift should not be attempted over 20 feet, except at low altitudes with the
equipment in new condition.
3. Suction Strainer too Near the Surface.
a. When pumping large volumes of water, the strainer should be submerged at least two
feet below the surface.
4. High Point in Suction Line.
a. Suction hose should slope down from pump to source.
b. If a high point cannot be avoided, re-prime several times to avoid air pockets.
5. Primer Not Operated Long Enough.
a. A normal prime should be accomplished within 20 seconds at a 10-foot lift.
6. Defective Priming Line.
a. Check hose from pump to priming valve and also hose from priming valve to the electric
priming pump. Check for leaks or accumulations of foreign material.
b. If necessary, refer to the electric priming pump operation instructions supplied
elsewhere in this manual.
Pump Will Not Deliver Capacity
1. Insufficient Horsepower.
a. Check engine according to manufacturers instructions, supplied with truck.
b. See local truck service garage.
2. Engine RPM too Low at Full Throttle.
a. Engine operated at high altitudes, engine horsepower decreases about 3 percent per
1000 feet above sea level. Consult manufacturers instructions. Also due to insufficient
horsepower.
3. Pump Wear Rings excessively Worn.
a. Excessive wear will allow severe internal leakage from the pressure side of the pump
back to the suction side, reducing the net pump capacity and pressure.
Engine RPM Higher than Necessary for Desired Volume in Pressure
1. Restriction in Suction Hose Strainer or Impeller Vanes.
a. Inspect strainer to clear away all debris.
b. Pressure backwash will usually clear impeller vane when pump is topped.
c. Check condition of the suction hose. On an old, or defective hose, the liner may be
pulled loose when pumping, thus reducing the inside diameter of the hose itself.
2. Undersize Suction Hose.
a. When pumping at higher than normal lifts, or altitudes, use a larger suction.
3. Truck Transmission in Too Low a Gear.
a. Proper pumping gear is usually high, or direct drive. Consult apparatus instructions.
Pump Will Not Develop Sufficient Pressure
1. Often the remedies for low pump capacity will also correct low pressure.
2. Pump RPM too Low
a. Use a tachometer to check engine speed.
3. Pump Capacity Limits Pump Pressure.
a. Do not attempt to pump a greater volume of water at a given pressure than the pump
was designed to handle. Cavitation will result. Pump efficiency will be seriously impaired.
(NOTE: Prolonged pumping while pump is cavitating will damage impeller.)
b. Reduce volume by restricting discharge until the desired pressure is obtained.

RECOMMENDED PREVENTIVE MAINTENANCE PROCEDURE
1. Lubrication.
The PSD pump utilizes oil-bath type lubrication of all gears and bearings in the pump transmission.
Oil level in the transmission should be maintained even with the oil level plug, which is located near
the input shaft on the front side of the gear case. It is recommended that the oil be changed every
three months and after any prolonged period of pumping. Check oil level at regular intervals.
Should your department be fortunate enough to have only a few calls during the year, it will be
beneficial to operate the pump once a week - perhaps during drill work.
IMPORTANT - MIDSHIP PUMPS WITH SPLINED INPUT AND OUTPUT SHAFTS REQUIRE
THE USE OF SAE 20 WEIGHT NON-DETERGENT MOTOR OIL. DO NOT USE HEAVIER
OIL.
MIDSHIP PUMPS WITH FLANGED INPUT AND OUTPUT SHAFTS REQUIRE THE USE OF
SAE EP-90 LUBRICANT. ALL OTHER PUMPS (FRONT MOUNTS, PTOs, ETC.) REQUIRE
THE USE OF SAE 20-WEIGHT NON DETERGENT MOTOR OIL. DO NOT USE HEAVIER
OIL.
WARNING: Insufficient oil will result in serious damage to the bearings and other internal
parts. Too much oil or too heavy oil will result in unnecessary loss of power and
unnecessarily high oil temperature. Drain oil and renew at least every 12 months.
WARNING: It is normal practice to ship pump to builder without oil, oil must be added
before operating.
2. Drafting.
When pumping large volumes of water, the strainer should be submerged at least two feet below
the surface. Use extra caution when drafting from shallow water sources with mud, sand or gravel
bottom. Keep the strainer off bottom by placing it inside a barrel with the top cut down, or use a
similar method.
3. Salt Water Use.
After pumping salt water, pump from a hydrant for a few minutes to flush out the pump. Also, follow
this procedure after pumping excessively dirty water.
4. Cold Weather.
It is recommended that during cold weather the pump should be drained at all times, except when
kept in a heated fire house.
CAUTION: If long runs in very cold weather are expected (such as in rural areas), it is wise
to maintain a dry pump regardless of storage conditions.
5. Final Test Before Housing Engine after a Fire or Drill.
In addition to regular lubrication and maintenance to the pump, the following procedure is
recommended to assure proper operation under emergency conditions:
a) Open discharge valves and remove caps.
b) Close drain valve(s).
c) Tighten suction caps.
d) Pull a prime until the compound gauge reaches about 20 inches of vacuum.
e) Watch gauge - if vacuum drops more than one inch in 10 minutes, an air leak is present. All air
leaks must be corrected before the pump may be considered fully serviceable.
Ball Bearings
Ball bearings are the most common anti-friction bearings used today and offer a major contribution
to the life of a fire pump, during major maintenance you will have an occasion to remove or replace
ball bearings. Often an attempt is made to reuse them and sometimes they can be; however, when
doing so you are taking a serious gamble, particularly when you have invested a great deal of time
and money to dismantle, repair and reinstall the equipment only to have a bearing fail after a few
short hours of operation, again requiring further downtime and additional money spent. We do not
recommend this practice under any circumstance, however, we realize at times this must be
considered, when doing so they must be examined very carefully for pits, abrasion or other
damage, check the raceways very carefully for metal transfer and pits. When cleaning ball
bearings, be sure to use clean solvent; do not use contaminated solvent. Use clean air to blow the
solvent and foreign matter from the inside raceway, do not hold the inner race rigid and spin the
outer race with air pressure; this can cause metal transfer or embed small particles. Hold both
inner and outer races and blow through the open sections around the separation. After examination
and the bearing appears to be satisfactory, lubricate the raceway with light oil and then holding the
inner race between the fingers slowly rotate the outer race and feel for any catch, rough spots or
binds. If any are found then discard the bearing and secure a correct replacement. Your best
supply for the correct type and size is the pump manufacturer. If locally supplied bearings are used,
be sure it is an exact replacement. Do not interchange bearing types; they may also fail
prematurely.
We have sketched two similar bearings that have the same outside diameter, same inside diameter
and the same width, but if one of these bearings is used to replace the other one you may be
asking for trouble. Design engineers and bearing manufacturers have spent a great deal of time
and effort to achieve the correct combinations of loads, speeds and other contributing factors to
assure long and dependable service. When a bearing is inadvertently or hastily replaced without
due consideration, you should not expect your equipment to operate as designed.
The standard Conrad type bearing shown on the left contains five balls and is a so-called standard
bearing. It will withstand moderate radial and combined thrust loads; however, the maximum
capacity bearing shown on the right contains more balls due to the loading groove and will
withstand considerable higher radial loads but less thrust loading. This bearing can replace the
Conrad type when very little or no thrust load is present; however, never replace the maximum type
with a standard Conrad type, when a bearing has the loading groove as shown, it most certainly
indicates high radial and very little thrust loads are present.

The PSD pump is an extremely rugged, dependable and versatile unit. Its transmission housing, gears, shafts, bearings, pump casings, and impeller are made of only the
finest materials. Years of engineering experience in hydraulic design and pump manufacturing stand behind beach unit and are in fact, the very reasons for its efficiency as
a hydraulic machine. Careful individual attention is given to each component as it is
machined to exact tolerances. Each pump is assembled by hand as a single unit. After
assembly and inspection, it is thoroughly tested under all phases of actual pumping
conditions.
In order that you realize the full value and advantages of this pump, it is suggested
that a few practices be carefully followed. All persons who will be responsible for the
actual operations of the pump should be thoroughly familiar with it and its operation,
both in theory and practice. This should include regular drills in pumping from draft,
hydrant, and booster tank. Careful instruction and practical experience will enable the
men and their equipment to work together as an effective firefighting team.
Regular and proper care of the pump itself and its related equipment (suction and
discharge hoses, gaskets, valves, etc.) is more important. A periodical schedule for
maintenance should be set up and strictly observed.
