EVAA field replaceable, three-part plunger seal providesthe wear surface between the plungerassembly and the plunger.A filter eliminates any contaminants from enteringthe pump’s plunger system.Air from the pressurized plunger system is ventedthrough an externally adjustable relief valve poppetlocated at the high point of the plunger system.A replenishment valve/replenishment check worktogether to insure excellent suction lift.1.5 STROKE LENGTH ADJUSTMENT ASSEM-BLYThe stroke length is fully adjustable from 0% to100% in 1% increments. The adjuster is fullysealed to prevent contamination or oil leakage.Also the stroke adjuster can be easily converted toan electronic stroke adjuster.1.6 GENERAL SPECIFICATIONSFlow Rate:0.049 GPH (0.18 L/H) to 23 GPH (88.5 L/H)Pressure:Up to 3500 PSIG (241 BAR)Turn Down Ratio:10:1 (optional 100:1)Steady State Accuracy:±0.5% of flow settingRepeatability:± 2% of full flowLinearity:± 1% of full flowMaximum Temperature:Metallic to 250 F (121 C)Non-metallic to 150 F (66 C)Paint:Powder Coating° °° °2
EVASECTION 2INSTALLATION2.1 UNPACKINGPumps are shipped f.o.b. factory or representativewarehouse and the title passes to the customerwhen the carrier signs for receipt of the pump. Inthe event that damages occur during shipment, it isthe responsibility of the customer to notify the carrierimmediately and to file a damage claim. Carefullyexamine the shipping crate upon receipt fromthe carrier to be sure there is no obvious damageto the contents. Open the crate carefully so accessoryitems fastened to the inside of the crate willnot be damaged or lost. Examine all materialinside the crate and check against packing list tobe sure that all items are accounted for and intact.2.2 STORAGEShort Term Storage (Less than 6 Months)It is preferable to store the material under a shelterin its original package to protect it from adverseweather conditions. In condensing atmospheres,follow the long term storage procedure.Long Term Storage (Longer than 6 Months)The primary consideration in storage of pumpequipment is to prevent corrosion of external andinternal components. This corrosion is caused bynatural circulation of air as temperature of the surroundingschange from day to night, day to day,and from season to season. It is not practical toprevent this circulation which carries water vaporand other corrosive gasses, so it is necessary toprotect internal and external surfaces from theireffects to the greatest extent possible.When the instructions given in this section arecompleted, the equipment is to be stored in a shelter;protected from direct exposure to weather.The prepared equipment should be covered with aplastic sheet or a tarpaulin, but in a manner whichwill allow air circulation and prevent capture ofmoisture. Equipment should be stored 12 inchesor more above the ground.If equipment is to be shipped directly from MiltonRoy into long term storage, contact Milton Roy toarrange for factory preparation.Pump Drive and Gearbox1. Flood the gearbox compartment with a highgrade lubricating oil/rust preventative such asMobile Oil Corporation product Mobilarma 524. Fillthe compartment completely to minimize air spaceand water vapor condensation. After storage,drain this material and refill the equipment with therecommended operating lubricant for equipmentcommissioning.2. Remove drive motors and mounting adapters,and brush all unpainted metal surfaces with multipurposegrease (NLGI grade 2 or 3). Store theseunattached.Pump Liquid Ends1. Flood the front compartment of the pump housingwith a high grade Lubricating Oil/Rust Preventativesuch as Mobil Oil Corporation product “Mobilarma527”. Fill the pump-housing compartment all theway to minimize airspace and water vapor condensation.2. Most of the liquid ends are constructed of inherentlycorrosion resistant materials and require noapplied corrosion inhibitor. If they are NOT naturallyresistant (test the threaded or flanged inlet and outletconnections - if they have little or now magneticproperty, they are resistant) they should be flushfilled with a corrosion inhibiting and non-freezing liquidwhich is compatible with the final pumped processchemical. Flush and fill with inhibitors such as“Mobilarma 524” or with a commercial automotiveantifreeze coolant. The pump head contains oneway check valves, so flush in a direction into thesuction (bottom) connection, and out the discharge(to) connection.3. Cap or plug all openings to capture the inhibitingfluid, and to prevent animals and insects from buildingnests.Pneumatic, Electrical and Electronic Equipment1. Motors should be prepared in the manner prescribedby their manufacturer. If information is notavailable, dismount and store motors as indicatedin step 3 below.3
