Transport
• All Hypro pumps are capable of being transported by air, sea, rail or motor vehicle. When the pump is shipped, ensure
that the pump is moved in accordance with local and national laws and is properly secured to prevent unwanted
movementwhichcouldcausedamagetopersonorproperty.Priortoshipping,alluidsshouldberemovedfromthe
pump.
Storage
• New pumps in their boxes can be stored several years as long as the port plugs are not removed. Once the plugs
have been removed, if the pump is not to be used for an extended period of time (i.e. more than 30 days), the pump
must be winterized as described in the Cleaning section of this manual.
Assembly and Installation
Assembly
• This pump comes completely assembled.
Installation
BeforeattemptingtoinstallyourHyprocentrifugalpump,itisimperativetoreadandunderstandthefollowing:
• InstallationofaHypropumpshouldonlybeperformedbyatechnicianhavingtheknowledgeandskillsnecessary
toinstallthepumpwithouttheriskofpropertydamageorinjury.
• 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.
• Pumping systems must be installed in accordance with Pentair installation instructions. Failure to do so will void
yourwarrantyandcouldcausedamagetoproperty,seriouspersonalinjury,ordeath.
• Electricalpowercablesandpumphosesmustberoutedwherethereisnoriskofpersonneltripping,walkinginto,
or falling because they have been routed in areas where personnel are expected to move. Electrical power cables and
pump hoses should be routed according to local and national standards.
• Itistheinstaller’sresponsibilitytoensurethatACelectric-drivemotors,Hypropumps,andmetalworkofsupport
structures are bonded to earth (ground), per local and national standards.
• It is the installer’s responsibility to conduct earth continuity tests between AC electric-drive motors, Hypro pumps,
andmetalworkofsupportstructuresandearthaccordingtoEN60204-1:2006/A1:2009,oritssupersedingstandard,to
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.
• 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.

• Theworkingpressureinthehydraulicssystemmustbecontrolledbyapressurereliefvalvethatisadjustedto
operateat10%ofthemaximumsystempressure.
• Wheninstalling,adjustingorremovingaHyprocentrifugalpump,ensurethattherearenoobjectswhichcanfall
ontheinstallerandmakecertainthatallmachinerytowhichthepumpistobeattachedisturnedoff.
• Pumps must be installed in a location where they are accessible for any necessary maintenance.
• Whenhydraulicpowerisused,thesystemshouldcontainaquickdisconnectcouplingthatcanbedisconnected
to isolate the pump.
• 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.
• When a main electrical supply is needed to power electric-drive motors, installers are responsible for ensuring
that a supply disconnect device, capable of isolating the machine from its electricity supply, be provided.
Standard Mounting
• Inordertopreventinjuryordamagetoproperty,allHypropumpsshouldbeproperlymountedtoasolidbasewhere
thereisnodangerofthepumpfallingorbreakingloose.AllHypropumpscomewithmountingholeswhichallowbolts
to be put into the pump so it can be secured to a sturdy base. When mounting your Hypro centrifugal pump, be sure to
use bolts and nuts which are compatible with any chemicals that may come into contact with them as well as choosing
the correct grade of bolt based on the pump weight and any expected loads. Pumps should be mounted as close to the
liquid source as possible. Non self-priming pumps must be mounted below the liquid level to function properly.
Pump Plumbing
• To achieve maximum pump performance, pump inlet and outlet lines should be at least the same size as their
respective port, and should have as few restrictions as possible. Pump plumbing must be capable of withstanding the
maximumsuctionandpressuregeneratedbythepump.Pumpsuctionlinemustalsobefreeofairleaks.Usegood
quality suction hose that will not be collapsed by suction.
• For best priming results, the recommended orientation for the outlet port is pointing straight up. The upper most vent
plugcanberemovedandaventlinecanbeinstalled.Thislinepreventsairlockandallowsthepumptoprimeitself
by bleeding off trapped air. Avoid any dips or bends in the suction line plumbing that could trap air.
Hydraulic Installation
• Prior to installation, refer to the tractor or sprayer manual and determine what type of hydraulic system is being used.
Thethreetypesofsystemsinclude:
• Open center systems
• Closed center (Pressure-Compensated) systems
• Closed center Load Sensing (Flow and Pressure-Compensated) systems
•Thehydraulicmotormustbecorrectlyconguredandsizedforthehydraulicsystem:
• Open center systems
• Excess oil from the hydraulic pump must be bypassed around the motor
   •Builtinbypassoptioninmotorendplate,orseparatebypassvalveinstalledinthelinefeeding 
the motor inlet.
• Use the largest motor possible
• Closed center (Pressure-Compensated) systems
  •Meteringoricesneededforoptimalperformance(seemeteringoricesectionbelow).
• Use the smallest motor possible

reducedseallife.Pressuresunder50PSI[3.4bar](20PSI[1.4bar]forGM1motors)arerecommended.
* For motors equipped with case drains the case drains must be used to minimize the pressure acting on the hydraulic
motor seal, and extend the life of the oil seal.
* The case drain line must be connected directly to the hydraulic reservoir with no restrictions, and the case drain port on
the motor must always be oriented upward.
THE CASE DRAIN PORT ON THE HYDRUALIC MOTOR MUST NEVER BE PLUGGED.

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.
When bypassing hydraulic oil, a large amount of heat can be generated which will damage the tractor’s hydraulic
system.Besuretomonitortheoiltempwhenbypassinghydraulicoil.
If the pump is not brought to a gradual stop, the sudden change in hydraulic pressure and pump RPM could cause
damage to the pump’s drive system.

Hypro’s obligation under this limited warranty policy is limited to the repair or replacement of the product. All returns will be tested per
Hypro’s factory criteria. Products found not defective (under the terms of this limited warranty) are subject to charges paid by the returnee
for the testing and packaging of “tested good” non-warranty returns.
No credit or labor allowances will be given for products returned as defective. Warranty replacement will be shipped on a freight allowed
basis. Hypro reserves the right to choose the method of transportation.
This limited warranty is in lieu of all other warranties, expressed or implied, and no other person is authorized to give any other warranty or
assume obligation or liability on Hypro’s behalf. Hypro shall not be liable for any labor, damage or other expense, nor shall Hypro be liable for
any indirect, incidental or consequential damages of any kind incurred by the reason of the use or sale of any defective product.
RETURN PROCEDURES
All products must be flushed of any chemical (ref. OSHA section 1910.1200 (d) (e) (f) (g) (h)) and hazardous chemicals must be labeled/tagged
before being shipped†to Hypro for service or warranty consideration. Hypro reserves the right to request a Material Safety Data Sheet from
the returnee for any pump/product it deems necessary. Hypro reserves the right to “disposition as scrap” products returned which contain
unknown fluids. Hypro reserves the right to charge the returnee for any and all costs incurred for chemical testing, and proper disposal
of components containing unknown fluids. Hypro requests this in order to protect the environment and personnel from the hazards of
handling unknown fluids.
Be prepared to give Hypro full details of the problem, including the model number, date of purchase, and from whom you purchased your
product. Hypro may request additional information, and may require a sketch to illustrate the problem.
Contact the appropriate Hypro Service Department to receive a Return Merchandise Authorization number (RMA#).
Returns are to be shipped with the RMA number clearly marked on the outside of the package. Hypro shall not be liable for freight damage
incurred during shipping. Please package all returns carefully. All products returned for warranty work should be sent shipping charges
prepaid:
