The SCP XP series large-flow centrifugal pumps are heavy-duty slurry handling pumps purpose-built for the most demanding oilfield blending, abrasive fluid transfer and corrosive media pumping applications. Designed for continuous high-load operation in fracturing blender slurry discharge, sand-laden cement mixing, drilling mud transfer, produced water injection and chemical stimulation services. The XP series covers three core models — XP 100, XP 200 and XP 300 — sharing a common heavy-duty power frame, bearing cartridge and mechanical seal arrangement for simplified fleet maintenance. Each model features a rugged volute casing with extra-thick wall sections, large-diameter shaft with short bearing span and replaceable wear components engineered to survive extended service intervals in abrasive and corrosive wellsite environments. All wetted parts are available in ductile iron, 316 stainless steel or duplex alloy for H2S sour service and high-chloride brine applications.
Extra-heavy-duty volute casing with thick wall sections for abrasive slurry erosion resistance
Oversized casing wall thickness provides extended erosion resistance in sand-laden fracturing slurry and cement mixing service, reducing casing replacement frequency compared to standard-duty centrifugal pumps.
Large-diameter shaft with short bearing span minimizes deflection under heavy radial loads
Oversized shaft diameter with close-coupled bearing arrangement limits shaft deflection to less than 0.002" at full load, protecting mechanical seal integrity and extending seal life.
Replaceable casing wear rings, impeller wear rings and shaft sleeve extend overhaul interval
Full set of replaceable wear components absorbs erosion damage, protecting the casing and shaft capital parts from premature wear and allowing cost-effective refurbishment at overhaul.
Heavy-duty duplex bearing cartridge with oil bath lubrication for 24/7 continuous service
Duplex angular contact bearing arrangement with oil bath lubrication handles combined radial and thrust loads during continuous 24-hour fracturing blender operations without overheating.
Centerline discharge nozzle orientation simplifies piping layout on blender skids
Top-centerline discharge nozzle arrangement provides symmetrical piping runs on standard blender skids, reducing piping stress and simplifying installation.
Available in ductile iron, 316 SS and duplex alloy for full corrosive service coverage
Three standard metallurgy options cover clean water through H2S sour brine and acid stimulation services without premium alloy surcharges for moderate corrosive duties.
Standard centerline-mounted foot support maintains alignment under thermal expansion
Centerline mounting allows the pump casing to expand radially under hot fluid service without shifting the shaft centerline, maintaining coupling alignment.
Oversized stuffing box accommodates standard and API-682 mechanical seal configurations
Large seal chamber space accommodates single, double and tandem mechanical seal arrangements with API-682 seal flushing plans, providing seal system flexibility for different fluid services.
Fracturing blender sand slurry discharge and recirculation pumping
Cement mixing and high-rate displacement for well cementing operations
Drilling rig mud mixing, transfer and charge pump services
Produced water transfer, injection and disposal well pumping
Acid stimulation fluid transfer and chemical injection services
Heavy crude and sand-laden oil transfer in gathering stations
High-volume water supply for hydraulic fracturing operations
Extra-thick casing wall sections provide 2–3 times longer erosion life than standard-duty centrifugal pumps
XP series casing wall thickness is 50–100% greater than equivalent API or ISO centrifugal pumps, directly translating to extended service life in abrasive slurry handling applications.
Large-diameter shaft with short bearing span eliminates deflection-related mechanical seal failures
The robust shaft design limits radial deflection to less than 0.002" at full rated load, eliminating the primary root cause of mechanical seal failure in high-specific-gravity slurry service.
Full replaceable wear component set enables cost-effective pump refurbishment without casing replacement
When wear components are consumed, only the inexpensive replaceable wear rings, shaft sleeve and impeller need replacement — the casing and shaft remain reusable for multiple service cycles.
Duplex bearing cartridge with oil bath lubrication handles continuous 7/24 high-load operation without overheating
Dual angular contact bearings with positive oil circulation maintain stable bearing temperatures below 160°F even during sustained high-load blender discharge service in desert summer conditions.
Oversized seal chamber with API-682 compatibility allows field upgrade to advanced seal systems without pump modification
The large seal chamber accommodates any API-682 seal arrangement — from simple single seals to pressurized double seals with Plan 53 or 54 flush systems — without pump modification.
Three metallurgy options (ductile iron, 316 SS, duplex) cover all oilfield fluid services from fresh water to sour brine
No need to source from different pump manufacturers for corrosive vs. non-corrosive service — the XP series offers all three material grades from the same pump platform.
Proven mass production and global export track record ensures competitive pricing and fast delivery
Large-batch production runs and established raw material supply agreements ensure short lead times and direct factory pricing for both single units and fleet orders.
Q: What is the maximum solid particle size the XP series can handle?
A: The XP series handles suspended solids up to 1/8" (3 mm) diameter in sand slurry and up to 1/4" (6 mm) in non-abrasive fluid services. Larger solids handling requires optional open impeller configuration.
Q: Can the XP 100, 200 and 300 models share the same baseplate?
A: Yes, all three models share identical baseplate mounting dimensions, nozzle centerline heights and shaft centerline elevations, allowing direct model swap on the same baseplate without piping modification.
Q: What mechanical seal arrangements are available for H2S sour service?
A: For H2S service, we recommend a double mechanical seal with API Plan 53 or 54 barrier fluid system, with duplex or Hastelloy wetted seal components for corrosion resistance.
Q: What is the maximum working temperature?
A: Standard construction handles up to 200°F (93°C). High-temperature options with upgraded bearing cooling, fluorocarbon elastomers and water-cooled bearing housing are available for up to 350°F (177°C) service.
Q: Do you offer complete pump-motor packages with VFD control?
A: Yes, we supply fully assembled pump-motor units with baseplate, coupling guard and optional VFD controller, ready for installation and start-up.
