Product Description (Continued)CoverStandard seal• The 3796 is available with a stuffing-box cover designed for a packing and a BigBore or a TaperBorePLUS seal chamber.Optional seal• a dynamic seal is available which uses a repeller to pump liquid out of the stuffing box while the pumpoperates. A static seal prevents leakage when the pump is shut down.This table describes the main parts of the power end.Table 4: Power endPartFrame adapterPower endShaftBearingsDescriptionThe ductile iron frame adapter has• a machined rabbet fitted to the seal chamber/ stuffing box cover• a precision dowel pin fitted to the bearing frame.• Flood-oil lubrication is standard.• No machining is required to convert from oil to grease or oil-mist lubrication.Regreasable bearings and oil-mist lubrication are optional.• The oil level is checked through a sight glass.• The power end is sealed with labyrinth seals.• The power end is made in the following sizes:• STi• MTi• LTiThe shaft is available with or without a sleeve.The inboard bearing• carries only radial loads.• is free to float axially in the frame.• is a single-row deep-groove ball bearingThe outboard bearing• is shouldered and locked to the shaft and housing to enable it to carry radialand thrust loads.• is a double-row angular-contact bearing, except for the LTi which uses a pair ofsingle-row angular-contact ball bearings mounted back-to-back.General description i-ALERT Condition MonitorDescriptionAlarm modeThe i-ALERT Condition Monitor is a compact, battery-operated monitoring device that continuouslymeasures the vibration and temperature of the pump power end. The condition monitor uses blinking redLEDs to alert the pump operator when the pump exceeds pre-set vibration and temperature limits. Thisallows the pump operator to make changes to the process or the pump before a catastrophic failureoccurs. The condition monitor is also equipped with a single green LED to indicate when it is operationaland has sufficient battery life.The condition monitor enters alarm mode when either vibration or temperature limits are exceeded overtwo consecutive readings within a ten minute period. Alarm mode is indicated with two red flashing LEDswithin two second intervals.Temperature and vibration limitsVariableTemperatureLimit195°F (91°C)22 Model 3796 i-FRAME Installation, Operation, and Maintenance Manual
Product Description (Continued)VariableVibrationLimit100% increase over the baseline levelBattery lifeThe i-ALERT Condition Monitor battery is not replaceable. You must replace the entire unit oncethe battery runs out of power.The battery life is not covered as part of the standard five-year pump warranty.This table shows the average condition monitor battery life under normal and alarm-mode operatingconditions.Condition monitor operational stateBattery lifeNormal operating and environmental conditionsAlarm modeThree to five yearsOne yearNameplate informationImportant information for orderingNameplate typesEvery pump has nameplates that provide information about the pump. The nameplates are located on thecasing and the bearing frame.When you order spare parts, identify this pump information:• Model• Size• Serial number• Item numbers of the required partsRefer to the nameplate on the pump casing for most of the information. See Parts List for item numbers.NameplatePump casingBearing frameATEXIECExDescriptionNameplate on the pump casing using English unitsProvides information about the hydraulic characteristics of the pump.The formula for the pump size is: Discharge x Suction - Nominal Maximum ImpellerDiameter in inches.(Example: 2x3-8)Provides information about the lubrication system used.If applicable, your pump unit might have an ATEX nameplate affixed to the pump, thebaseplate, or the discharge head. The nameplate provides information about the ATEXspecifications of this pump.If applicable, your pump unit might have the following IECEx nameplate affixed to thepump and/or baseplate. The nameplate provides information about the IECExspecifications of this pump.Model 3796 i-FRAME Installation, Operation, and Maintenance Manual 23
