First Choice for VerticalIn-line PumpingThe HWX pump is the API 610latest edition type OH3, bearinghousing design and space-savingin-line alternative for many over-hung process pumps in upstreamand down stream services.
The HWX family of pumpsconsists of designs to API OH3,OH4 and OH5 configurations formeeting customer specificneeds.
The most stringent emissionscontainment is achieved as theAPI 682 seal chambersaccommodate all mechanicalseal styles including advancedgas barrier seal technology.
The HWX pump is the industryleader for these reasons:• Robust construction to
meet pressure, temperature,nozzle loading and safetyconsiderations required byAPI 610 and other industryor user specifications
• Most comprehensivehydraulic coverage in theindustry
• Variety of materials andbearing housing lubricationoptions
• Completely removable, backpull-out design
• Low flow/high head hydraulicoptions– OH3: HWM, HWM-2 – OH4: MSP– OH5: WM, WM-2
• Customized hydraulics– OH4: DSVP– OH5: PVML,
PVML-Mag Drive• Rigid coupled design

The Flowserve HWX pump linemeets or exceeds the rigorousrequirements of API 610, latestedition. It encompasses a familyof eleven distinct designs pro-viding the most comprehensiverange of pump configurationsand hydraulic coverage availableto the industry.
These space-saving pumps areengineered and built for reliableand safe performance in cryo-genic, high temperature andhigh working pressure services.
Special HWX OH3 Features• Choice of bearing lubrication
type– Oil cascade lube design for
temperatures to 385°C(725°F)
– Oil mist design fortemperatures to 400°C(750°F)
– Grease lube design for tem-peratures to 275°C (525°F)
• Only two bearing housingframes and bearing sets for allOH3 pumps
• Top bearing isolator, optional Inpro
• Flexible disc spacercoupling design
• Standard fan air cooling forgrease and oil sump bearinghousings. Fan cooling notapplicable or needed for oilmist designs
• Complete back pull-out design• Accommodates NEMA, IEC
and existing field drivers(C-face and P-base)

Motor Support Head is a heavy-duty design with a registered fitmotor mount. Generous size opencompartments allow easy access toall bolting and removal of the com-plete pumping assembly, includingmechanical seal, without removal ofcasing
Adjustable Axial Screws allow foreasy driver mount positioning andare provided where dowelling ofdriver is not possible or practical
Coupling Guard is provided toenclose the coupling, pump shaftand motor shaft areas
Dynamically Balanced Impellerlimits vibration and assures smoothoperation over wide flow range• Casting techniques and
manufacturing processes forfine finish, high efficiency
• Positively locked, anti-rotationimpeller nut with threads unexposed to pumped liquid
Raised Face Flanges are to ASMEB16.5 for Class 300. Surface finishmeets API 610 standard. ISO flangesand flanges with JIS drilling areavailable
Pump Casing and Cover featuremetal to metal fit with fully confined,controlled compression gasket toensure proper sealing and alignment
Back Pull-Out of rotating assemblyfor OH3 and OH4 models simplifiesmaintenance as neither the motornor piping connections are disturbed
Standardized Mounting Plate isprovided to maintain the API 3:1ratio from the unit center of gravityto prevent tipping. Larger platesprovided as required to accommo-date mounting of seal pot assemblies and heat exchangers
HWX Line Features
API 682 Seal Chamberaccommodates a wide variety of seal configurationsincluding dual pressurizedand unpressurized cartridgetypes for the most severeservices. A full complementof API 610 seal flush plansis available. Shaft sleeveand gland plate constructedof stainless steel for optimumseal life
Cartridge Seal Mountingassures:• Ease of maintenance• Precise seal face setting
for maximum seal life
Fan Cooling* of bearinghousing permits handling ofextreme temperatures withoutthe need for water cooling* Not applicable or needed for oil
mist designs
Renewable Wear Rings*for both the casing andimpeller reduce replace-ment cost• Secured by axial screws,
with option for tackwelding
• Back wear ring standard• Rear rings and balance
holes eliminated for highsuction pressureapplications
* Not applicable or needed for lowflow impeller designs
Stiff Shaft Design limitsmaximum deflection atseal faces to 0.05 mm(0.002 in) maximum. Shaftstiffness factors (L3/D 4) arethe best in the industry
