flowserve.comTSPTwin-ScrewPumpGRGearexMSPVersatile and ReliableThe Flowserve TSP double-suction, twin-screw rotarypump is the most versatile of all viscous liquid pumps.Built upon the proven heritage of the Sier-Bath twinscrew positive displacement pump, the TSP continuesto provide the same pulse free flow, high suction liftand self priming capabilities of its predecessor, nowincorporating field proven design enhancements tofurther improve reliability and ease of maintenance.These advanced features, coupled with the wideapplication coverage of this product clearlydemonstrate the versatility of the Flowserve TSP.Advantages Over Gear Pumps Lower NPSH requirementsHigher differential pressure capabilityLower shear stressGreater solids capabilityLower operating noise levelsApplications Crude oil transferFuel oil burner feedCargo loading and unloadingGeneral petroleumChemical dosingLube oil transfer and feedHigh viscosity polymersReactor re-circulationGreases and fatsPulp and paperSlurriesBenefits of the TSP Ease of Maintenance– Back pull-out design of rotating assembly– Split bearing bracket construction– Cartridge type mechanical seals– Tapered shaft mounting of coupling hub– No special tools required Versatility– High volumetric efficiency over a wide rangeof viscosities– Run-dry capability– High temperature operation– Accommodates multiple seal types Heavy-Duty Reliability– Robust, one-piece cast casing design– Oversized and rigid integral shaft design– Oversized bearings– Abrasion-resistant coatings Low Total Cost of Ownership– Individual serviceability of bearings andmechanical seals– Refurbishing program for shafts and casings– Replaceable rotating assemblyComplementary Pump DesignsFlowserve also offers these pump designs: GR double helical, non-timed internal bearinggear pump Gearex double helical, timed external bearinggear pump MSP vertical in-line, medium speed pump3

TSPTwin-ScrewPumpThe Flowserve TSP features a double-suction, timedtwin-screw pump design built in accordance with API676, latest edition. It improves upon traditional rotarypump designs by providing smoother, more constantflow across a wide range of viscosities, temperaturesand pressures.The bearings and timing gears are located in separate oilreservoirs to ensure long pump life and high reliability. Thisdesign is suitable to handle fluids that are contaminated orhave poor lubricity. It is also preferred for high temperatureand high viscosity services or where run-dry capability is anoperational requirement.Operating Parameters 4Flows to 2550 m3/h (11 200 gpm)Pressure to 100 bar (1450 psi)Temperatures to 450 C (850 F)Viscosities to 200 million SSUSlurry concentrations to 70% by weightShaft tip speeds to 30 m/s (100 ft/s)Double Suction Design contributes to low NPSHRand balanced hydraulic loads. Robust cast casing hasvery low inlet losses and ensures mechanical sealsare exposed only to pump inlet pressureExternal Bearings and Timing Gears are located inseparate oil reservoirs, thereby eliminating exposureto the pumped fluid. This design provides ideallubrication for these critical componentsOversized, Integral Shaft Designresults in low operating shaft deflections and hightorque handling capabilityVersatile API 682 Seal Chamber readily accommodates multiple seal types without field modificationsand meets HSE regulationsSplit Bearing Bracket Construction provides easyaccess to bearings and mechanical seals to facilitatemaintenanceAGMA 11 Precision Ground Timing Gears transmitpower from the pump drive shaft to the driven shaftand maintain rotational clearances between thescrews. Metal-to-metal contact is eliminated therebyreducing wear

flowserve.comCustomized Screw PitchDesign capacity and required pressure are achieved byvarying the screw pitch in 3 mm (1/8 in) increments, therebyachieving the optimum hydraulic and mechanical efficiencies.Pumps can then be coupled to standard synchronous speeddrivers reducing original equipment costs. Utilizing state-ofthe-art manufacturing methods precise tolerances can beconsistently achieved.Flowserve Multiphase Twin-Screw PumpThrust Bearing DesignThe TSP incorporates this field proven feature from theFlowserve multiphase twin-screw pump design. This innovative design provides a robust outboard bearing support forthe between bearings mounted timing gears, ensuringoptimum timing gear alignment and mesh resulting in lowoperating vibration levels. This well engineered bearingdesign provides for a simple and controlled method forbearing installation that can be carried out in the field.Split Bearing Bracket ConstructionA strong maintenance feature of the TSP is the splitbearing bracket design. The bearing housing portionof the bracket can be separately removed to permitservicing of the bearings without disturbing themechanical seals. Since the parting flange of thebracket is near the TSP casing maximum access isprovided to the mechanical seals, which similarlycan be individually removed and replaced withoutdisturbing the seal on the adjacent shaft. The criticalpositioning of the bearing bracket assembly ismaintained using hardened dowel pins so properreassembly is assured.Tapered Coupling ExtensionThe TSP’s tapered coupling extension eliminates themaintenance challenge of removing interference-fitmounted coupling hubs, especially at remote fieldlocations. As a result, pump downtime is significantlydecreased and the potential for damaging the pumpdrive shaft and/or coupling hub is eliminated.5

Hard coatings also offerthe additional benefit of protection against galling inthe event of short-term upset conditions. The result isincreased mean time between pump repair.Materials of ConstructionComponentCasingIntegral shaftsSeal plate half of bracketBearing housing half of bracketFront cover; Gear housingRear capsTiming gears Casing bores can be coated with overlays with aminimum hardness of 70 Rc Screw outer diameters can be manufacturedwith abrasion-resistant coatings with a minimumhardness of 40 Rc In-house testing lab to confirm pressure andvelocity load handling characteristics of coatingsStandard DesignAPI DesignDuctile ironCast steelCarbon steelCarbon steelCarbon steel plateCast steelCast steelCarbon steelCase carburized carbon steelTSP Range Chartgpm m3/h700060001400TSP-275-61060Hz Coverage Chart(Product Viscosity of 100 25-215TSP-075-13560barpsi 051015200202530400Differential Pressure354045600700Corrosion-Resistant DesignStainless steelStainless steelStainless steel
