MATCHED PRECIPITATIONMP Rotators now come in two precipitation rate options toprovide maximum flexibility for your irrigation design.Standard MP Rotator Precipitation RateThe Standard MP Rotator has the slowestprecipitation rate in the industry at approximately0.4 in/hr, preventing runoff in the majority of soilapplications, and allowing for gentle hydrationof the landscape.MP800 Precipitation RateThe MP800 has a precipitation rate of approximately0.8 in/hr, allowing for high-efficiency irrigation ofsmall spaces and medium-grade soils.0.4"0.8"1 hour1 hourStandard MP Rotator 0.4 in/hrMatching Soil Intake RatesMatching your precipitation rate to your soil intake rate willeliminate the hazards of runoff and help conserve water.With two different precipitation rate options with theMP Rotator, you can now choose the best high-efficiencyrotary nozzle for your plant material, soil type, and slope.Standard MP Rotators deliver water slowly, at a rate thatmost soils and slopes can effectively absorb.The MP800 delivers water at half the rate of a spraynozzle, better matching typical soil intake rates. Standard sprays apply water at a rate much higher thanmost soils can absorb, causing runoff in most soil types.MP800 0.8 in/hrINFILTRATION RATES BY SOIL TYPESLOPE PERCENTAGE0-5%5-8%8-12% 12%COARSE SANDFINE SAND–SANDY LOAM–FINE SANDY LOAM––LOAM/SILT LOAM––––CLAY/CLAY LOAM–Water infiltration into the soil is less than:1.5 in/hr   1 in/hr   0.5 in/hr– Cycle and Soak required to avoid runoff3

MP ROTATOR DESIGN GUIDELayout and PlacementRun TimesBecause the MP Rotator applies less water with increaseduniformity, simply doubling the run time used fortraditional spray nozzles may supply sufficient water to thelandscape while using less water overall.You can also calculate the run time based on the lowerprecipitation rate.Visit www.hunterindustries.com/tools/runtime for moreinformation on run time calculations.Precipitation Rate CalculationsMP Rotators are recommended for use with head-to-head coverage in either square or triangular layouts.Square Spacing Application RateEquilateral Triangular Spacing Application Rate96.25 #GPM of 360c sprinkler(Head spacing # Row spacing)96.25 #GPM of 360c sprinkler(Head spacing # Head spacing) 0.866Example:Example:96.25 # 1.48 GPM 142.45 0.39 in/hr(19'# 19')36196.25 # 3.64 GPM350.35350.35 0.45 in/hr(30'# 30')0.866(900) 0.866779.419' Square Spacing30' Triangular SpacingMP2000-36040 PSI19' Radius1.48 GPM19' Head x 19' Row,Square SpacingMP3000-36040 PSI30' Radius3.64 GPM30' Head x 26' Row,Triangular SpacingNote: Equilateral triangular spacing has a higher application rate than square spacing due to less area per sprinkler.Zoning with the MP RotatorThe standard MP Rotators have a matchedprecipitation rate of approximately 0.4 in/hr.This means any standard MP Rotator at any arcor radius can be placed on the same zone.The MP800SR can be configured to work wellin head-to-head coverage in either square ortriangular layouts. When square spacing isused, the resulting precipitation rate will beapproximately 0.8 in/hr.Since this precipitation rate differs from thestandard line of MP Rotators, you should zonethe MP800 family separately to maintainmatched precipitation within each zone.ZONE 1 MP800 MP815ZONE 2 MP1000 MP20005

MP ROTATOR DESIGN GUIDEMP8000.8in/hrMatched PrecipitationMaximize water savings for tight spaces with the MP800. The MP800 offers the benefits of multi-stream, multi-trajectorytechnology in smaller areas than ever before. The MP800 delivers water to distances as short as 6' at a matchedprecipitation rate of approximately 0.8 in/hr, less than half that of traditional spray nozzles.RadiusArc90 º to 210 º210 º to 270 º360 -90MP815-210MP815-360Pressure RatingsThe MP800, just like its larger family of MP Rotators, prefers 40 PSI for optimal performance. This pressure yields optimalresults for coverage and distribution uniformity. However, to achieve the lowest radius setting of 6', you must regulate theinlet pressure to 30 PSI. Use a Pro-Spray PRS30 to achieve a consistent inlet pressure of 30 PSI.Pro-Spray PRS30Pair the MP Rotator with aPro-Spray PRS30 to achievethe minimum radius.6Pro-Spray PRS40Pair the MP Rotator witha Pro-Spray PRS40 forpeak performance.

MP ROTATOR DESIGN GUIDECost and Water SavingsLower System CostA design with MP Rotator nozzles uses far less material and equipment than a traditional spray design, resulting in anoverall reduced project cost. Due to the lower flow rates, more heads can be run at once, reducing the number of valvesneeded.Learn more about how the MP Rotator provides material and labor savings in this residential site study:http://hunter.direct/mprotatorss.Design Using Traditional SpraysDesign Using MP RotatorsPatioPatioResidenceResidenceWWAAPorchPorch DrivewayDrivewayIRRIGATION SYSTEM COST COMPARISONIRRIGATION SYSTEM COST COMPARISONMaterials NeededWith SpraysMaterials NeededWith MP Y COST MP ROTATOR COST 10

MP ROTATOR DESIGN GUIDEFiltration Recommendations and Wastewater ApplicationsFiltration GuidelinesYou should use primary filtration when operating withdirty water.A general rule is to use primary filtration that is fivetimes the mesh rating of the nozzle filter. For example,if the nozzle filter is 20 mesh, the primary filter shouldbe 100 mesh.HY-100, HY-100-75, HY-075Height: 6"Width: 3"Depth: 5"Field testing has shown that the MP800SR runs wellin dirty water conditions with the use of a 120-meshprimary filtration system.NOZZLE FILTER SIZESNozzleScreen Size (mesh)MP100040MP200040MP300020MP350020MP Strips and Corner40MP800SR-9060MP800SR-36040MP81540Hunter’s HY filters with 150-mesh size are a great solutionfor zone-specific MP800SR arrangements.Reclaimed WastewaterThe MP Rotator is an excellent choice when using reclaimed wastewater.
