SXWA55G50N | Triplex Pump, 5.5 GPM 5000 PSI, 1750 RPM

Annovi Reverberi SXWA55G50N Industrial Triplex Pump | 5.5 GPM 5000 PSI 24mm Shaft

The Annovi Reverberi SXWA55G50N is a high-output industrial triplex
plunger pump delivering 5.5 GPM at 5,000 PSI at a controlled
1,750 RPM — engineered for surface preparation, heavy equipment
washing, contractor pressure wash rigs, and continuous-duty industrial cleaning
systems where both high flow and extreme pressure must be sustained reliably across
long operational shifts. Built with a 24 mm solid keyed shaft,
abrasion-resistant ceramic plungers, heavy-duty stainless steel valves, and an
oil-lubricated crankcase with oversized bearings, the SXWA55G50N
is designed to withstand the demanding pressure cycles, heat buildup, and mechanical
loads that lighter-duty pumps cannot sustain.

Every SXWA55G50N is factory-tested, pre-filled with break-in oil, and shipped with
a performance test report verifying PSI and flow output to rated specifications —
backed by a 5-year commercial warranty with U.S.-based service
support. The 24 mm solid keyed shaft supports both belt-drive and direct-drive
integration, making the SXWA55G50N a practical choice for OEM skid builders,
contractors building custom wash rigs, and industrial operators replacing pumps
in existing high-pressure systems.

How the SXWA55G50N Delivers 5,000 PSI Performance

Triplex Plunger Design for Extreme-Pressure Continuous-Duty Operation

The SXWA55G50N uses a triplex plunger system where three ceramic
plungers operate in a synchronized reciprocating sequence — drawing water through
stainless steel inlet valves and discharging it at rated 5,000 PSI pressure through
stainless discharge valves in an overlapping cycle that produces steady,
pulsation-free flow. This balanced three-cylinder architecture distributes mechanical
load evenly across the crankshaft and bearings, reducing the vibration and peak stress
that single or dual-piston designs create at equivalent high-pressure output.

The ceramic plungers are specifically chosen for extreme-pressure
service — ceramic’s superior hardness and low thermal conductivity minimize friction
at the packing interface and reduce heat transfer into the seal stack during
continuous 5,000 PSI cycling. This directly extends water-seal and packing service
life compared to steel or chrome plunger alternatives at equivalent operating
conditions. The stainless steel valves maintain precise intake and
discharge timing at elevated pressure, ensuring volumetric efficiency and consistent
5.5 GPM output are maintained across long hose runs and variable tool demand.

The oil-lubricated crankcase with oversized bearings keeps the
rotating assembly continuously coated and supported at 1,750 RPM under the high
radial and axial loads generated by 5,000 PSI working pressure — the combination
of controlled speed and adequate bearing sizing is what allows the SXWA55G50N to
sustain continuous-duty operation where high-speed pumps at equivalent pressure
overheat and wear prematurely.

SXWA55G50N Key Benefits

Why This Pump Handles What Lighter-Duty Alternatives Cannot

• 5.5 GPM at 5,000 PSI — extreme-pressure industrial output:
  the combination of high flow and 5,000 PSI working pressure places the
  SXWA55G50N in the professional surface preparation and heavy industrial
  cleaning class — more cutting power than commercial wash pumps at
  a sustained output that lighter-duty alternatives
  cannot maintain
• 1,750 RPM controlled speed reduces continuous-duty wear:
  running at 1,750 RPM instead of 3,400 RPM means substantially less heat,
  less seal cycling, less valve fatigue, and reduced bearing load per hour
  of operation — the physics of slow-speed design compound into
  significantly longer service intervals
• 24 mm solid keyed shaft for flexible drive integration:
  compatible with belt-drive sheaves and direct-coupling hardware across
  OEM skid builds, contractor rigs, and industrial system replacements
  without custom adapter hardware
• Ceramic plungers built for 5,000 PSI continuous cycling:
  ceramic’s hardness and low thermal conductivity are specifically
  advantageous at extreme pressure — protecting the packing stack
  from heat-induced degradation that accelerates in
  high-PSI applications
• Stainless steel valves maintain precision at extreme pressure:
  consistent sealing performance across the elevated suction and discharge
  pressure differentials created at 5,000 PSI — protecting
  volumetric efficiency and output stability
• Oil-lubricated crankcase with oversized bearings:
  designed for the sustained radial and axial loads of 5,000 PSI
  operation — not adapted from a lower-pressure platform with
  inadequate bearing sizing
• Factory-tested and performance-verified: every
  SXWA55G50N ships with a test report confirming rated PSI and
  GPM output — no guesswork on whether your pump
  meets specification
• 5-year commercial warranty: industry-leading coverage
  for an industrial-class high-pressure pump — backed by U.S.-based
  service centers and the global Annovi Reverberi
  parts network

SXWA55G50N Typical Applications

Where 5.5 GPM at 5,000 PSI Delivers Industrial Results

• Surface preparation: concrete cleaning, steel surface
  profiling, and paint stripping where 5,000 PSI mechanical impact is
  required for proper surface profile and coating adhesion
  preparation results
• Heavy equipment washing: mining, construction, and
  agricultural machinery where compacted soils, grease, and baked deposits
  require sustained 5,000 PSI output to remove efficiently from
  large equipment surfaces
• Contractor-grade pressure wash rigs: trailer-mounted
  and skid-mounted contractor systems where the SXWA55G50N’s 24 mm keyed
  shaft, 5,000 PSI output, and 5-year warranty make it the
  right professional-grade pump investment
• Industrial cleaning plants: factory sanitation,
  production equipment washdown, and process cleaning in food and beverage,
  general manufacturing, and chemical processing facilities where
  continuous-duty 5,000 PSI operation is required
• Marine and dock cleaning: vessel hulls, dock structures,
  and marine hardware where the stainless steel internal components
  resist the corrosion that saltwater environments
  accelerate in lesser pumps
• Fleet maintenance: truck wash bays, rental fleet
  turnover stations, and municipal service centers where sustained
  5,000 PSI output across long daily operating cycles demands the
  durability that the SXWA55G50N’s slow-speed triplex
  design provides

SXWA55G50N Installation & Maintenance

Best Practices for Sustained 5,000 PSI Performance

• Verify drive system RPM before installation: confirm
  your belt-drive or direct-drive configuration delivers the correct
  1,750 RPM to the SXWA55G50N shaft — overspeeding at 5,000 PSI
  operating pressure dramatically accelerates seal and
  bearing wear
• Mount on a rigid, vibration-resistant structure:
  adequate structural support is critical at 5,000 PSI — transmitted
  vibration into the manifold and crankcase accelerates fastener
  loosening and seal fatigue on high-pressure pump assemblies
• Feed clean, filtered water from adequate supply:
  install an upstream inlet strainer and ensure the water supply line
  provides adequate NPSH — cavitation at 5,000 PSI damages ceramic
  plungers and valve seats rapidly
• Size the unloader and relief valve correctly: system
  protection components must be rated for 5,000 PSI with appropriate
  safety factors — undersized unloaders create pressure spikes that
  exceed the pump’s working pressure rating
• Check oil daily using sight glass and dipstick:
  verify level via sight glass before each shift and confirm with
  the dipstick — adequate oil is the most critical factor in
  bearing longevity at 5,000 PSI continuous-duty operation
• Never run the pump dry: even brief dry operation
  at 5,000 PSI pressure rating destroys ceramic plunger packings
  and voids the 5-year warranty — always confirm water supply
  before starting
• Flush after cleaning chemicals: always run clean
  water through the SXWA55G50N after chemical applications to protect
  stainless valve seats and manifold passages
  from residue buildup
• First oil change at 50 hours: then follow
  duty-cycle-based service intervals — high-pressure continuous-duty
  applications require more frequent attention than
  intermittent use
• Winterize before cold storage: drain completely
  or use pump-safe antifreeze — freeze damage to manifold passages
  or plunger bores at this pressure class requires full
  wet-end rebuild
