    The HED family of two-stage, radially split pumps isparticularly well suited for high-temperature processapplications, such as those found in hydrocarbon pro-cessing, power and specialty services. This family ofpumps fills the performance range between the single-stage HDX pump and multistage, double-case pumps.

    Available with either a single- or double-suction, first-stageimpeller, the pumps feature heavy-duty, single or dual volutecasings with a staggered arrangement for extended pumpreliability and life.

    Meeting Industry NeedsThe HED and HED-DS are fully compliant with API 610 (BB2)standards. The pumps incorporate all of the design require-ments specified by the demanding hydrocarbon processingand power industries. These include:

    API 610 specified nozzle loads and shaft run-out requirements

    API 682 mechanical seal chambers Centerline-mounted casing Bearing options Materials options Control and monitoring systems Low NPSH capabilities

    Broad Application Petroleum refining, production and distribution Heavy-duty chemical and petrochemical processing Liquefied gas industry service Boiler feed Heavy-duty utility service

    Complimentary Pump DesignsType HED and HED-DS pumps may be used withmany other Flowserve pump designs, including:

    Radially split, overhung process pumps Single stage, between bearings pumps Multistage, between bearings pumps Vertical, double-case pumps

    HED-DS Double-SuctionDesign

    Double Casing Covers facilitate maintenance.Gasketing is metal-to-metal fit, fully confined andcontrolled compression to ensure proper sealingand alignment when handling hot liquids

    API 682 Seal Chamber accommodates a wide varietyof seal configurations, including dual pressurized andunpressurized cartridge types for the most severeservices. A full complement of API 610 seal flushplans is available. Seal chambers are maintained atcomparable pressures by a pressure equalizing linefitted on the discharge side chamber

    Raised Face Flanges meet ASME B16.5 criteriafor Class 600. Surface finish is in accordance withAPI 610. Class 300 and 900 flanges are availableupon request

    Renewable Casing and Impeller Wear Rings aresecured by locking pins or threaded dowels. Wearrings economically restore pump efficiency andmaintain operational stability. Optional non-metallicwear rings are available in PEEK and other specialty materials

    Cartridge Seal Mounting ensures precise sealface setting for maximum seal life while easingmaintenance

    Fully compliant with the latest edition of API 610 (BB2),the Flowserve HED pump is a between bearings, radiallysplit, two-stage, single-suction hydrocarbon processingpump. The similarly configured HED-DS boasts adouble-suction, first-stage impeller for services withvery low NPSHA or higher flow rates. Both pumps areCE compliant and engineered to provide safe, reliableoperation in the elevated temperatures experienced inrefining and power applications.

    Operating Parameters Flows to 2000 m3/h (8500 gpm) Heads to 750 m (2500 ft) Pressures to 80 bar (1200 psi) Temperatures to 450C (840F) Speeds to 3600 rpm Specific gravities down to 0.35

    Dual Volute ConstructionThe HED and HED-DS feature heavy-duty casings with eithersingle or dual volute staggered arrangement construction.Both configurations ensure radial balance over the fulloperating range. Detrimental shaft deflection and vibrationare virtually eliminated.

    Dynamically Balanced ImpellersPrecision cast impellers are dynamically balanced to reducevibration and ensure hydraulic efficiency.

    Impellers are positively locked to the shaft toeliminate vibration

    Ceramic core casting technology produces incrediblysmooth passages, improving pump efficiency

    Face-to-face impeller mounting of the HED results in axialthrust balance over the entire operating range of the pump

    The double-suction, first-stage impeller of the HED-DSminimizes axial thrust problems, reduces NPSHrequirements and allows mechanical seals to operateat equal and low pressure

    Oil-Lubricated BearingsBearings are lubricated by means of a slinger or ring oilsystem. This lubrication system prolongs bearing life byensuring the oil penetrates the bearings without foaming.

    Standard single row, self-aligning radial bearing Standard dual single row, back-to-back thrust bearings Optional bearing arrangements and lubrication system

    are available to meet application requirements

    Carbon Steel Bearing HousingWith standard labyrinth type oil seals, the carbonsteel bearing housing is designed with 360 boltingto the mounting bracket.

    Available bearing isolators prevent oil loss andcontamination

    Optional fan-cooled bearing housing permits usein extreme temperatures without water coolingsystems

    Stiff Shaft DesignStiff shafts ensure trouble-free operation belowthe first critical speed. A short bearing span and aheavy shaft minimize deflection under all operatingconditions.
