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 Piston 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 Hypro 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..

- 12 -
• 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 Piston pump the system must be properly aligned with the
inlet and outlet ports.
• Wheninstalling,adjustingorremovingaHyproPiston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 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 should 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basewhichallowthe
pump to be secured. When mounting your Hypro Piston 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.
Pump Plumbing
• Pump inlet and outlet lines should be at least the same size as their respective port. Pump plumbing must be capable
of withstanding the maximum suction, and pressure, generated by the pump and should have as few restrictions as
possible.

Belt & Pulley Drive Installation
▫Pulley Driven-Mountpulleysasclosetopumpandmotorengineshaftbearingsaspossible.Checkalignment
with a straight edge as shown in Fig. 1.
▫Makesurethatbelthaspropertension.(Toomuchtensionwillcausebearingwear;toolittlewillcauseslippage.)SeeFig.2.
▫ Checkwithbeltandpulleysourcesforspecicrecommendation.Togureproperdiameterofpumppulley,multiply
motor/enginerpmbydiameterofthemotor/enginepulleyanddividethatgurebydesiredpumpspeed.Beltand
pulley drive systems are typically used to reduce pump speed. For determining proper pulley sizes, use the formula
below as a guideline and use “A” or “B” section belts.
Motor RPM =Flow (@ Rated Speed) =Pump Pulley Dia.
Pump RPM Flow (Desired) Motor Pulley Dia.
Example:
• Usea1725RPMelectricmotortodriveapumpat950RPM.
• Typically, a pulley diameter on the motor is 3.4 inches. The pump pulley diameter can be determined from the formula
above:
1725 RPM =Pump Pulley Dia.
950 RPM 3.4”
• Solving this equation for the Pump Pulley diameter yields:
1725 RPM x 3.4” = 6.2”
950 RPM
• Refertopumpperformancechartstodeterminedesiredspeedandtoobtaindesiredmaximumow.
• Flexible Coupling - To install couplings, slide coupling ends onto motor or engine and pump shafts as far as possible.
Mountengine/motorandpumponbase.Shimuppumporpowertoalignshafts.Leaveenoughroombetweenshaft
ends to install center disc. When aligned, slide ends over disc. Select couplings rated twice required horsepower
whenusingmotor;threetimeswhenusinggasengine.
d
L
Push the belt midway between the pulleys, check
the deflection (d) and adjust: d = 0.016 x L
Four points of

NOTE: Pump may
be mounted in other
orientations with
respect to the motor
or engine.
CAUTION:
For safety, always install a
shield over rotating shafts
and couplings.

Control Systems
• All pump systems with electric, hydraulic power sources and gas engines are required to have a control system which
meets all local and national standards.
• Overloadandshort-circuitprotectiondevicesshouldopenatacurrentthatis10%higherthanthenormalloadcurrent.
• For more detail on a typical system installation, see preceding subsections of the “Assembly and Installation” section
of this manual.
Direct Drive - Hollow Shaft Installation
Hollow shaft models mount directly on the motor or
engine shaft. After mounting the pump, always turn
itbyhand tomakesure thepumpis operatingfreely.
Neverapplypowertoapumpthatappearstobestuck.
CAUTION: Use a torque arm to keep the pump
from rotating with the shaft. The pump must be
allowed to float on the shaft and must not be tied
rigidly to the equipment on which it is mounted.
CAUTION:
For safety, always install a shield
over rotating shafts. Or enclose
the pump/motor assembly inside
a housing.

Information
• When running Hypro Piston pumps it is essential that operators use hearing protection as the sound levels can
reach levels of 80 decibels.
• 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.
• OnlyauthorizedoperatorshavingtheknowledgeandskillnecessarytosafelyuseaHypropump,orany
equipment the pump is connected to, may run the pump.
• Whensprayingmanuallyitisrecommendedthatchemicalresistantfacemasksandclothingbeworntoprevent
anychemicalsfromcomingintocontactwiththeskinorbeinginhaled.
• When spraying manually always spray upwind of yourself as long as the sprayed chemical will not drift into the
vicinity of other people.
• Wheninstalling,adjustingorremovingaHyproPiston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.
• Hypro Piston pumps should only be used on tractors or tow behind spray platforms which have electrically
conductivetiresinordertoreducetheriskofelectrocution.
• NeveroperateaHyproPistonpumpfromoutsidewhilethereisachanceofgettingstruckbylightning.
• Never leave electrical wires or plumbing components where they can be a tripping hazard or become entangled
inamovingcomponent.Ideallyelectricalcables,hoses,pipesandttingsshouldberoutedoverhead.Intheevent
electrical wiring must be routed over the ground operators are required to use rubber ramps if they cross a gangway.
• IfusersofaHyproPistonpumpareusingaPTOshaft,exiblecouplingorbeltdrivetheyarerequiredtouseCE
approved PTO shafts and guards
• Hypro Piston pumps should not be used if the ambient light is below 200lux.
• For Piston pumps which use gas engines the user should always ensure the exhaust is properly attached to the
engineandisnotleaking
Only use approved chemicals in your pump, for a complete list of approved chemicals see the “Fluid
Pumping Applications” section. Failure to follow this warning will void your warranty and could lead to property
damage, serious injury or death.
Start-up, Operation, Shutdown
Before Starting the Pump
• Ensure all unnecessary personnel are clear of the area
• Forinitialsetupandtestofyoursystem,itisrecommendedtostartwithcleanwaterinsteadofchemicals,andconrm
thesystemandplumbingconnectionsareleakfree.
• Ensurethatthereisuidinthesourcetankorsupplyline.Donotrundry.
• Checklinestrainerfordebrisorclogs.Removeanyfound.
• Checkallplumbingconnectionstomakesuretheyaretight.
• Checkpowersourceandconnections.
• Checkallvalvesandregulatorsaresettothedesiredsettingandarefunctioningproperly.
• Ensure all hoses are properly positioned and are not damaged in any way.
• Ensure PTO shaft shields are in place and are not loose

- 16 -
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)
• 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.A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.
