KERR TROUBLE SHOOTER GUIDE
REASON OR SERVICE NEEDED
Unusual pounding, knocking broken valve spring Insufficient fluid at high speed. Check to see if the suction line is
the proper size and is not constricted, trash in line, valve partly
opened, etc. There is also a possibility of gas in the fluid causing
the roughness.
Loss of pressure or volume Also above. Foreign matter may be holding valves open. Worn
valves. Broken springs.
Consistent, rhythmic knock Improper bearing adjustment. Worn bearings or connecting rods.
NOTE: Valve noise is common and normal in high-speed pumps.
It should not cause concern unless it becomes erratic.
Packing failure (Excessive) Improper installation. Improper type lubrication.
Incorrect type packing for particular installation.
(Contact Kerr Pumps if in doubt) Excessively worn plungers.
Abnormal wear of fluid end parts Abrasive or corrosive fluid.
Abnormal wear of power end parts Lack of oil, overload on pump, foreign matter in oil.
Heat in power end A new pump will run hot for a short period (2 or 3 days). Check
above for persistent heating. Pump will operate near 140˚F.
under average conditions.
Check for air in pump by bleeding at cover caps. Too much
spring tension Reciprocating pumps have very limited pick up,
check installation section.

INSTALLATION INSTRUCTIONS (SEE ILLUSTRATION)
The importance of proper installation cannot be overstressed. As the reciprocating pump is almost unable to lift fluid, proper
suction flooding is a must. This is the First step toward satisfactory operation.
The Kerr Pumps Engineering Service will be happy to advise you in your installation problems. As almost every installation
varies, you cannot exercise too much care in making certain your installation is proper.
Before Starting The Pump, read carefully the maintenance section in the following pages.
To start the pump, open the suction line valve and permit the intake chamber to fill on the pump. Air may be bled off by
opening the valve covers slightly until there is a constant fluid flow. After bleeding, open the discharge line valve and start the pump.
Roughness may occur from cavitation (air in line) or from starvation (lack of fluid). Eliminate these troubles before permitting
continuous operation.

RECOMMENDED INSTALLATION OF KERR PUMPS
FOR BEST RESULTS
(A) PRESSURE RELIEF VALVE (OPTIONAL)
(B) BY-PASSED FLUID SHOULD BE PIPED BACK IN SUCTION SUPPLY TANK WHEN POSSIBLE
(C) USE FLEXIBLE HOSE IN DISCHARGE LINE WHEN POSSIBLE
(D) DISCHARGE SHUT-OFF VALVE (OPTIONAL-USED FOR TOTAL SHUT-DOWN OR SERVICE ONLY)
(E) DISCHARGE AND SUCTION ON EITHER SIDE OF FLUID END ON ALL MODELS.
(F) PULSATION “DAMPENERS” MAY BE USED IN EITHER THE SUCTION OR DISCHARGE PIPING OR BOTH.
DISCHARGE DAMPENERS SHOULD BE CAPABLE OF HANDLING PUMP DISCHARGE MAXIMUM PRESSURE
CAUTION SHOULD BE TAKEN TO KEEP FITTINGS OUT OF THE SUCTION AND
DISCHARGE PIPING AS THESE WILL RESULT IN POOR PERFORMANCE. EACH
90-DEGREE TURN IN THESE LINES RESULTS IN GREAT LOSS OF PUMPING

SERVICE PROCEDURES (ALL MODELS)
1. VALVES (Wing-guided type):
A. Discharge Valves: The discharge valve and seat can be exposed by first removing the discharge valve cover cap. Once
the discharge cover cap has been removed you may lift out the discharge valve spring and the discharge valve. The
valve seat will be held in place by a taper fit and must be “pulled” with an appropriate valve-pulling tool (available
from the Kerr Pumps Dealers). Once the valve and seat have been removed they should be resurfaced or replaced if
badly worn. To replace the discharge valve, first clean and inspect the seat bore for washout defects and then drop the
seat into the bore. Replace the valve into the seat and strike the top of the valve a couple of good blows utilizing a
brass bar and hammer to seat the valve seat in the fluid end valve bore. Replace the valve spring and cover cap after
inspecting the spring and the seal of the cover cap.
B. Suction Valves: The suction valves are located in the chamber directly behind the suction or end valve cover caps.
The suction valves are serviced in the identical manner as the discharge valves. Note: Discharge valves must be
removed prior to any removal of the suction valves.
Service Procedure for KZ-3150 Valves
C. DISCHARGE VALVE: The discharge valve and seat can be exposed by first removing the discharge valve cover
plate. Once the discharge cover cap has been removed you may lift out the discharge valve spring, discharge valve
and valve seat. Once the valve and seat have been removed they should be replaced if badly worn. To replace
discharge valve, first clean and inspect the seat bore for wash out defects and then drop the seat into the bore.
Replace valve in seat then valve spring and cover cap, always-inspecting o’ring seals between seats and cover caps.
D. SUCTION VALVE: The suction valves are located in the chamber directly below the discharge valve seat. The
suction valves are serviced in the identical manner as the discharge valves.
2. VALVES (Disc-type): All disc-type valves are exposed for removal in a similar manner as the wing-guided valves. Instead
of removing the valve body; the upper portion of the valve is removed by removal of the valve capscrew, spring retainer, valve
spring, and valve spacer sleeve. The valve seat is then “pulled” from the fluid-end utilizing an authorized Kerr Valve Puller.
Note: In all Kerr Pumps with disc-type valves the discharge and suction valves are identical.

-10-
3. VALVES (Ball & Seat): In Kerr Pumps with block/billet type fluid-ends the valves are ball and seat design. These are
exposed for removal/inspection by removal of the appropriate valve cover. The flat seats are kept in place by a screw-in valve
retainer that can be best removed with a Kerr Valve Wrench made for the appropriate pump. Springs are normally
incorporated with the discharge valves while the suction valves operate with a “free ball”. A copper washer/gasket is used
under all valve seats for a seal. When installing or removing a flat type valve seat a good “rap” on top of the valve wrench will
“seat/unseat” the seat and copper gasket prior final tightening or removal. Failure to “seat” the valve seat in this manner can
result in the “washing out” of the fluid-end. For pressurized suction, valves will need to be spring loaded. Call Kerr Pumps
for this change.
4. PLUNGERS: Following the removal of the suction valve, the plunger may be removed by breaking the union between the
plunger and pony rod and forcing the plunger out the back of the fluid-end. Loosening the packing nut/gland will facilitate the
removal of the plunger. The reverse of this procedure is used to install a plunger. Lubrication and some slight force may be
used to pass plunger through the packing. Always retighten the plunger and pony rod union periodically following the removal
of the plunger to insure it is securely made up and will not vibrate loose.
5. PLUNGER PACKING: This manual includes illustrations of the packing sets for each model pump. Generally, once the
plunger has been removed from the pump, the packing can be exposed for removal by completely removing whatever device is
used to tighten the packing (i.e. the packing or stuffing box nut or gland). There will be various amounts of metal rings and
packing components depending upon the type of packing and the model of pump (refer to appropriate illustration or chart).
After the removal of all rings and equipment from the stuffing box; thoroughly clean it and inspect for damage, which might
keep the new packing from working properly. If the stuffing box is in satisfactory condition, install the new packing as per the
appropriate illustration. It is a good idea to lubricate new packing with a light oil prior to installation. Most of the standard
packing used in Kerr Pumps should be tightened with the original equipment-packing wrench while the pump is running
under normal operating pressure. After a two or three hour run-in, check the packing for tightness and re-adjust as necessary.
Packing should be checked for tightness on a periodic basis, but it is not a good idea to attempt to periodically tighten the
packing as part of routine maintenance. This tends to “wear out” the packing prematurely. When the packing leaks in an
excessive amount it should be replaced. There is no value in constantly “re-tightening” leaking packing.
If your pump is equipped with optional “spring loaded” packing, there is no adjustment in this equipment during its operational
life. The stuffing box nut is initially tightened as much as possible and there is no further adjustment. Note: In all cases the
spring goes in the stuffing box before the packing rings.

-11-
When using the optional Kevlar or Teflon packing, be sure to rotate the “splits” so that none are “aligned” to insure that the
packing holds properly. Normally, this packing is not lubricated and requires less tension on the stuffing box nut during
operation.
CAUTION: An “airtight” seal is not desirable with this plunger packing. Some slight dripage is desirable during operation.
Attempts to tighten packing until it completely “seals off” will result in premature failure from too much friction. The Kevlar
& Teflon packing must be allowed to drip a small amount to assure normal life.
6. PONY ROD and PONY ROD PACKING: Kerr Pumps use two pony rod sealing arrangements, models KD-1250, KJ-2250,
KM-3250 and KCP-6300 use a screw in seal gland, all other models use a bolt in seal gland, these glands use press in oil seals
with snap ring retainers. Some Bolt in gland use adjustable packing arrangements with bolt in or screw in followers to adjust
packing. By unscrewing plunger from pony rod a gap may be facilitated to allow the removal of the various sealing
arrangements. A special wrench will be needed to remove and replace pony rod to crosshead. (This wrench is available from
Kerr Dealers) All pony rods have a jam nut to align tighten pony rod to crosshead, care must be exercised in installing new
seal on pony rod not to damage it.
7. DISASSEMBLY OF POWER END. (CAUTION: Prior to disassembly of any power end, the plunger, pony rod, and pony
rod seal housing must be removed.) Expose the crankshaft and connecting rods by removing the pan cover. Connecting rod
caps may now be removed and the connecting rod and crosshead should be shoved all the way to the rear (toward the fluid
end) to facilitate crankshaft removal out either side as convenient. The connecting rods and crossheads may now be taken out
the front cavity exposed by removing the crankshaft. Connecting rods may be removed from the crosshead by loosening the
setscrew and driving out the wrist pin from the crosshead. A bronze bushing is used in the rod it may be driven out of the rod
and replaced with a new bushing. Reassembly is the reverse of the above outlined sequence with the following considerations
for “fits” or tolerance:
A. General: All Kerr components are machined on modern production machine tools and are of the same specifications
and close tolerances you would expect in a modern automobile engine. It must be pointed out that at top speed (350 to
400 RPM) your pump will not even be approaching idle speed for a gasoline engine so “field fits” are possible and
practical when making repairs and replacements away from the factory. All procedures outlined below are possible
with only hand tools and absolutely no instruments, special tools, or gauges are needed.
B. Connecting rod and wrist pin: Proper fit will find the wrist pin turning freely in its bore in the connecting rod, but it
should have no “wobble” that is discernable up and down the main axis of the connecting rod. This looseness in the

-12-
wrist pin fit is the most probable cause of “knocking” which is traceable to the power end of most all pumps. The only
solution for loose fitting wrist pins is to discard the connecting rod wrist pin bushing and replace with a new one. If
any wear is visible on the wrist pin it should always be replaced.
C. Crankshaft End Play and Lateral adjustments: Adjustment of the Taper Roller bearings used in all Kerr Pumps is
accomplished by removing or adding shims under the bearing housing. Shims are taken out or added until the
crankshaft (without connecting rods) will turn freely, but with no endplay felt when attempting to pull or push the
jackshaft end of the crankshaft along its long axis. Some lateral adjustment is possible by removing shims from one
side of the crankshaft and adding them to the opposite side. (Note: Lateral adjustment is the “centering” of the
crankshaft in the power frame housing.)
D. Connecting Rod to Crankshaft fitting: Factory bored connecting rods will normally fit the standard crankshaft journal
just by bolting the cap on the rod with the standard rod shims being used. If the caps do require adjustment this is
accomplished by removing or adding various thicknesses of rod shims. The standard connecting rod shim used on all
Kerr Pumps is 1/32” thick and is comprised of .002” laminates, which can be “pealed “ off separately. Proper fit of the
connecting rod will allow the pump crankshaft to be rotated while not allowing in-and-out slack in the connecting rod
along its long or main axis. A well-fitted rod will have none of the in-and-out slack, but should be free enough to be
moved from side to side on the rod journal. This insures the rod not being too tight. A point of caution when installing
the connecting rod assembly in the pump is to make certain the oil holes in the rod are “UP” and not toward the bottom
of the pump. This will result in lubrication failure in these parts and the pump will fail in a short period of time. An
additionally important step is to make sure that the rod cap is bolted back on the rod as it came off. The rod and cap
carry a “mark” or “number” which allows you to match them back properly. Failure to do this will cause the rod not to
fit the journal for which it was made.
8. Power End/Fluid End Connection: A common misconception is that there is some form of fluid seal between the power end
and the fluid end. This is false. The fluid end is merely bolted to the power frame. It can be removed by breaking the
plunger connection, backing off the packing nut or gland, removing the various fluid end bolts, and sliding the entire fluid end
off the power frame. Corrosion may tend to seize the two components together making their separation difficult in some
isolated cases. On models KP-3300, KT-3350/KT-3400 and R335/R340 the bolted in stuffing box assemblies must be
removed prior to removal of the entire fluid end. They are held in place by four studs each. On all other units the stuffing
boxes can be left intact. On the remaining pumps (with the exception KD-1250B, KJ-2250B, KM-3250B, and KCP-6300) the
stuffing boxes are held in place in the fluid end by a friction or “press” fit. They should be removed with a hydraulic press if
possible. These press-in type stuffing boxes carry a gasket and/or an o-ring to insure a good seal. The boxes on the KD-
1250B, KJ-2250B, KM-3250B, and KCP-6300 are screw-in type and carry only a copper gasket.
