ponents. Perform routine maintenance as required
(See Repair Instructions).
9. Use only pipe, hose and fittings rated for the maxi-
mum psi rating of the pump.
10. Do not use these pumps for pumping water or other
liquids for human or animal consumption.
11. Do not run pump with discharge fully closed for over
two minutes.
Notes are used to notify of installation, operation, or
maintenance information that is important but not safety
related.
Caution is used to indicate the presence of a hazard,
which will or may cause minor injury or property damage
if the notice is ignored
Warning denotes that a potential hazard exists and indi-
cates procedures that must be followed exactly to either
eliminate or reduce the hazard, and to avoid serious per-
sonal injury, or prevent future safety problems with the
product.
Danger is used to indicate the presence of a hazard
that will result in severe personal injury, death, or prop-
erty damage if the notice is ignored.
Do not pump flammable or explosive fluids such as gas-
oline, fuel oil, kerosene, etc. Do not use in explosive at-
mospheres. The pump should be used only with liquids
compatible with the pump component materials. Failure
to follow this notice may result in severe personal injury
and/or property damage and will void the product war-
ranty.
1. Always drain and flush pump before servicing or dis-
assembling for any reason.
2. Always drain and flush pump prior to returning unit
for repair.
3. Never store pumps containing hazardous chemicals.
4. Before returning pump for service/repair, drain out
all liquids and flush unit with neutralizing liquid.
Then, drain the pump. Attach tag or include written
notice certifying that this has been done. It is illegal
to ship or transport any hazardous chemicals with-
out United States Environmental Protection Agency
Licensing.
Never use your hand to check the condition of hydraulic
lines or hoses. If hydraulic fluid penetrates the skin, get
medical help immediately. Failure to get proper medical
help may result in loss of limb or life. The safest way to
check hydraulic lines or hoses is by holding a piece of
cardboard next to the hydraulic line or hose.
The sound pressure level of the Pump is 80dBA. Ob-
serve all safety precautions when operating the pump
within close proximity for extended periods of time by
wearing hearing protectors. Extended exposure to ele-
vated sound levels will result in permanent loss of hear-
ing acuteness, tinnitus, tiredness, stress, and other ef-
fects such as loss of balance and awareness.

Hydraulic Pumps
Hydraulic pumps come in two basic types:
•Constant displacement - which will continue to put
out its rated flow regardless of pressure, until the re-
lief valve bypasses the flow.
•Variable displacement - which will produce only the
flow needed by the implement until the total pump
output is reached. If less than the full pump output
isrequired,anautomaticstrokecontrolmechanism
decreases the pump output to maintain a constant
pressure and flow. The output varies according to
demand.
The Closed Center Valve (See Figure 2) is used with variable
displacement pumps. The flow is completely shut off in the
neutral position, causing the pump stroke to adjust to zero
flow. The flow stops, but the pump maintains a static pres-
sure up to the valve.
Spool Valves
Therearetwobasictypesofspoolvalvesusedinconjunction
with these pumps — Open and Closed Center. In the Open
Center Valve (See Figure 1), the flow goes straight through
the valve when in the neutral position. This type is used for
constant displacement pumps where the flow should never
be shut off.

Hydraulic Motors
Figure 3 shows an internal gear motor (Gerotor) where pres-
sure causes the cavities between the gears to expand on one
side, developing torque. The Gerotor type of hydraulic motor
is used on Hypro pumps for its superior performance charac-
teristics, including cooler running and higher rpm capabilities.
Three Systems
Fitting these components together and installing a motor,
we have one of the three types of systems: Open Center,
Closed Center (pressure compensated) and Closed Center
Load Sensing (flow and pressure compensated).
Open Center Systems
In an Open Center System, the hydraulic pump puts out a
constant flow. If the pump puts out more oil than the mo-
tor can use, a portion of the oil must be bypassed around
the motor. When the oil is bypassed around a loop and does
nowork,theenergyputintoitbythepumpturnsintoheat.
Therefore,the amountof oilbypassed shouldbe keptto a
minimum. Use the largest motor possible.
Closed Center (Pressure-Compensated) Systems
The Closed Center Pressure-Compensated system has a
variable displacement pump which will deliver flow at the
necessary rate to maintain a specified pressure.
Note: This pump is not configured for use with these
systems.
Closed Center Load Sensing Systems
(Flow and Pressure-Compensating)
The Closed Center Flow-Compensated System is a variation
of the pressure-compensated system, designed primarily for
more efficient operation and the generation of less heat. It
works on the principle of maintaining a constant pressure
dropfromthepumptotheworkportoftheselectorvalve.Any
variation in demand at the motor will cause a change in flow.
The system senses this change in flow due to the change
in pressure drop across the valve and causes the pump to
compensate by varying the pump flow. No restrictor is used
in the pressure line and no oil is bypassed.

conrmthatallcomponentsthatneedtobeconnectedtoeartharesatisfactorilybonded.
• It is the installer’s responsibility to conduct electrical tests in accordance with EN60204-1:2006/A1:2009, or its
supersedingstandard,onnishedpumpassemblies.
• All connections to electrical components must be number, symbol, or color-coded generally as recommended by
EN60204-1:2006/A1:2009, or its superseding standard.
• Installers must provide hydraulic components that are capable of withstanding maximum source pressure.
• Theworkingpressuremustbecontrolledbyapressurereliefvalvethatisadjustedtooperateatamaximum
pressure of the hydraulic motor.
• For pumps with gas engines, the exhaust must be directed away from operators and anyone standing nearby to
ensure that exhaust fumes do not enter their breathing zone.
• If a rigid plumbing system is to be used on a Hypro centrifugal pump, the system must be properly aligned with
the inlet and outlet ports.

All Models — Open Center Systems
ModelsincludeTankPortAdapterwithbuilt-inCheckValve
Assembly and Pressure Port Adapter.
Preliminary to Mounting
Consult the owners manual to determine the type and
capacity of the hydraulic system. Make sure the hydraulic
system is recommended to operate with a continuous load.
Refer to the Pump Selection Guide at www.hypro.pentair.
com to confirm you have the proper pump for your hydraulic
system.
Checktoseethatthepumpimpellercanbeturnedbyhand.
(Turn the shaft clockwise using a deep socket wrench on
the impeller nut.) If it cannot be turned, open the pump
casing to look for obstructions. Clean out any corrosion
buildup where the casing fits over the eye of the impeller.
Pump Inlet Line
To achieve full capacity from the pump, the inlet line
should be at least the same size as the inlet port on the
pump. Reducing this line size will restrict the capabilities
ofthepump.Thelinemustalsobefreeofairleaks.Check
all fittings and connections in the suction line for tightness.
The introduction of air may affect the priming and pumping
capabilities of the pump. Use good quality suction hose
that will not be collapsed by suction.
Pump Outlet Line
The recommended orientation for the outlet port is pointing
straight up. This allows liquid to stay in the pump while
it is priming. The outlet line should be the same size as
the pressure port on the pump to give the optimal flow.
The line should have as few restrictions and elbows as
possible to optimize the pump performance and reduce
pressure drop from the pump to the discharge point.
Priming the Pump
The pump must not be run dry.
Before starting the pump, the chamber needs to be filled
with liquid. The pump must not be run unless it is completely
filled with liquid because there is a danger of damaging
the mechanical seal, which depends on the liquid for its
lubrication.
Self-priming models can be primed by removing the top vent
plug and filling the priming chamber. The priming chamber
will fill to the level of the inlet port. After use, the priming
chamber should be flushed and drained to avoid chemical
corrosion and damage from freezing. Drain by removing the
lower drain plug.
Hooking Up the Hydraulic Motor to the
Tractor Hydraulic System
Hypro Series 9300HMC hydraulic motor-driven pumps
can be mounted on either the tractor or sprayer. When
hooking up, make sure that no dirt or liquid gets into the
hydraulic motor. Keep all hydraulic connections clean.
The recommended filter for the hydraulic motor removes
particulates greater than and including 10 microns. The
>10 micron filter should be placed on the return line of the
hydraulicsystemtomitigatetheriskofcontaminatingtheoil
tank.Besuretoconnectthehydraulicmotorintothesystem
correctly by putting the pressure line to the pressure port
andreturn line to the tankport. The ports on thehydraulic
motor are sized to accommodate 7/8” and 1 1/16” SAE
fittings. For maximum performance, the hydraulic lines
should also be at least 1/2” [12.7 mm] in size. For lines
longer than 8 feet [2.44 m], hydraulic line size should be at
least 3/4” [19.05 mm] in order to reduce heat generation.
Standard spool valves, which are found on all tractor
hydraulic systems, may cause potentially damaging high
peak pressures in the hydraulic system when closed,
because of abrupt shut-off of oil flow in both the supply and
return lines. When shutting off the pump, move the selector
to the FLOAT position to allow the centrifugal pump to come
to a stop gradually.
Installation Instructions

L-1581 Rev. A (10/18)

Open Center Systems - All Models
Adjusting Centrifugal Pump Output
1. Install a shut-off valve and pressure gauge on the dis-
charge line for initial setup.
2. Openthebypassadjustmentscrew2-1/2turnsfromfully
closed. Turn the bypass screw in to achieve the flow for
the desired gpm and psi.
3. Start the tractor. Leave the directional valve in the neutral
position and allow hydraulic oil to circulate for approxi-
mately 10 to 15 minutes or until adequately warmed.
4. Prime the centrifugal pump with all valves open (See
the Installation Instructions and System Configuration Di-
agram).
5. Once the pump is primed, shut off the dischage line and
monitor the pressure. Shut-off pressure is not to exceed
60PSI.Adjustdischargescrewaccordingly.
Closed Center (Load Sensing) All Models
Many tractors are being introduced with load sensing sys-
tems (also referred to as flow and pressure- compensated
systems) which simplify system setup and eliminate many
of the problems associated with using the wrong size pump
motors on a given hydraulic system. Usually, any of Hypro’s
9300HMC models may be used on this type of system, pro-
vided the hydraulic system produces sufficient oil flow for the
hydraulic motor being used (Refer to the Pump Selection
Guide).
This system maintains a constant flow of hydraulic oil for a
givenpressuredrop.Theflowisadjustablewithaflowcontrol
valve installed in the hydraulic system (such as the Tortoise/
Hare control on John Deere tractors). Because this system
hasadjustableflow,thereisnoneedtobypasshydraulicoil
as in an open center system, or to restrict the flow with ori-
fices as in a closed center pressure- compensated system.
Adjusting Centrifugal Pump Output
1. Install a shut-off valve and pressure gauge on the dis-
charge line for initial setup.
2. Closeandlockdownthebypassadjustingscrewinthe
hydraulic motor.
3. Set the tractor hydraulic flow control valve for minimum
hydraulic oil flow to the remote outlet (Tortoise position).
4. Start the tractor and allow the hydraulic oil to circulate
for approximately 10 to 15 minutes or until adequately
warmed.
5. Prime the centrifugal pump with all valves open (See the
Installation Instructions and System Configuration Dia-
gram).
6. Shut off the discharge valve and monitor the pressure.
Slowlyadjustthetractorhydraulicflowcontrolvalveuntil
the pump deadhead pressure approaches 60 PSI.
Storage
1. Drain pump. Flush pump after use.
One of the most common causes for faulty pump perfor-
mance is gumming or corrosion inside the pump. Flush
the pump and entire system with a solution that will
chemically neutralize the liquid pumped. Mix according
to the manufacturer’s directions. This will dissolve most
residues remaining in the pump, leaving the inside of
the pump clean and ready for use.
2. Store pump in a clean, dry environment.

Maintenance and Servicing
Information
• All maintenance should be done when machinery is stationary and has been isolated from its energy sources.
It is dangerous to perform maintenance while machinery is still connected to its power source. Machinery should be
isolated from its electrical, hydraulic or gas engine power source.
• Be sure to release all pressure from the system before performing any sort of maintenance on a Hypro pump.
• DO NOT perform service or maintenance to the pump, or attached components, until the pump unit is below
109°F(43°C).
• The lubrication of this pump unit has been done at the factory prior to shipping.
• When handling Hypro pumps, one should wear steel-toed shoes and protective gloves in order to protect the feet
in the event the pump is dropped and protect the hands from any sharp surfaces on the pump or chemicals. If the
pump is being repaired while the pump is in service, eye protection should also be worn.
Any hazardous liquids should be disposed of in a manner which complies with local and national regulations. Never dump
uidsontotheground.
Disposal
WhendisposingofaHypropump,besuretoremovealluidsfromthepumpbeforescrapping.Theseuidsshouldbe
disposedofinamannerwhichcomplieswithlocalandnationalregulations.Neverdumpuidsontotheground.Oncethe
pumpisfreeofalluids,itmaybescrappedinaccordancewithlocalandnationallaws.
Cleaning
Yourpumpwilllastlongerandgivebestperformancewhenproperlytakencareof.Properpumpcaredependsonthe
liquidbeingpumpedandwhenthepumpwillbeusedagain.Aftereachuse,ushpumpwithaneutralizingsolutionforthe
liquidjustpumped.Followwithacleanwaterrinse.Thisisespeciallyimportantforcorrosivechemicals.Itisgoodpractice
to clean the pump after each use to prevent deposits from forming and damaging the pump. For infrequent use and before
long periods of storage, drain pump thoroughly. Open any drain plugs, remove suction hose from liquid, and blow pump
drywithair.Anantifreeze/rustinhibitorshouldbeinjectedintothepumpbeforebothportsarepluggedandthepumpis
stored.Plugallportstokeepoutairuntilpumpisusedagain.
