SHP2050HN | 5.3 GPM 7250 PSI Pump 1450 RPM SHP Series Duty

Annovi Reverberi SHP2050HN Industrial Pump | 5.3 GPM 7250 PSI 24mm Nickel-Plated

SHP2050HN — the Annovi Reverberi SHP Series super high-pressure
industrial triplex plunger pump delivering 5.3 GPM at 7,250 PSI
at a controlled 1,450 RPM on a 24mm solid keyed shaft
— engineered for heavy manufacturing and fabrication facilities, industrial
surface preparation and coating removal, high-pressure cleaning of large machinery
and industrial infrastructure, centralized multi-station cleaning systems, and
marine and construction specialty cleaning rigs where 7,250 PSI ultra-high-pressure
output at 5.3 GPM delivers the hydraulic power that standard
industrial pump platforms cannot produce. The SHP2050HN is the
higher-flow SHP Series variant — delivering 1.34 GPM more than the SHP1550HN
at identical 7,250 PSI pressure for faster coverage, higher-throughput blasting
operations, and multi-station systems where flow volume at ultra-high pressure
is the governing system design requirement. The HN designation confirms
nickel-plated forged brass head and valve caps with a
high-efficiency manifold design for enhanced corrosion resistance in marine,
coastal, and chemically aggressive industrial environments. Backed by a
5-year commercial warranty with AR North America’s nationwide
U.S.-based service centers and domestic WSHPWR fulfillment.

SHP2050HN vs. SHP1550HN — Choosing the Right Flow at 7,250 PSI

5.3 GPM vs. 3.96 GPM at Identical Pressure — The System Design Decision

The SHP2050HN and the SHP1550HN share the same 7,250 PSI
pressure rating, same HN nickel-plated construction, same 24mm solid keyed
shaft, and same SHP Series ultra-high-pressure platform. The difference is
flow volume and the power requirement that comes with it.

The SHP2050HN delivers 5.3 GPM at 25 EBHP —
the correct choice for centralized multi-station systems supplying two or more
ultra-high-pressure work points simultaneously, large-surface coating removal
and concrete preparation where coverage speed drives productivity, and
high-throughput blasting operations where water volume at 7,250 PSI determines
how much surface area is processed per shift.

The SHP1550HN delivers 3.96 GPM at 20 EBHP — the correct
choice for single-gun hydrostatic testing, targeted descaling of heat
exchangers and specific equipment components, and installations where the
available engine or motor is in the 20–24 HP class rather than the 25 HP+
class the SHP2050HN requires.

The practical selection is driven by two questions: how much surface area or
system throughput does the application demand, and what engine or motor is
available? If the power plant supports 25 EBHP at 1,450 RPM and the
application benefits from higher flow — specify the SHP2050HN.
If 20 EBHP at 1,450 RPM is the power ceiling — specify the SHP1550HN.
Contact WSHPWR for system specification guidance before ordering
either variant.

High-Efficiency Nickel-Plated Manifold Design

SHP2050HN Construction for Ultra-High-Pressure Industrial Environments

The SHP2050HN’s nickel-plated forged brass manifold features
a high-efficiency manifold design — an architecture that optimizes internal
flow passages for reduced turbulence and improved volumetric efficiency at
7,250 PSI, while the nickel plating provides the corrosion and chemical attack
resistance that marine, shipyard, coastal industrial, and chemical processing
environments demand.

The oversized SKF tapered bearings are a specification detail
worth noting for system builders evaluating long-term operating costs. SKF
bearings at this duty point are precision-rated for the radial and axial load
combination generated by a 25 EBHP triplex pump at 1,450 RPM — properly
matched bearings at this load class extend crankshaft bearing service intervals
and reduce the risk of the bearing failures that cause unplanned downtime in
continuous-duty ultra-high-pressure industrial systems.

The aluminum oxide blend ceramic plungers are precision-ground
for dimensional stability under the thermal and pressure cycling of 7,250 PSI
continuous duty. Aluminum oxide ceramic is specifically chosen for this
application class for its combination of hardness, thermal conductivity,
and resistance to the micro-fracturing that extreme pressure cycling can
induce in lower-grade ceramic formulations.

SHP2050HN Key Benefits

Highest-Flow SHP 7,250 PSI Platform — Nickel-Plated, SKF Bearings, Continuous Duty

• 5.3 GPM at 7,250 PSI — maximum flow in the
  SHP nickel-plated lineup: 34% more flow
  than the SHP1550HN at identical pressure —
  the specification for multi-station systems,
  large-surface preparation, and
  high-throughput blasting operations
• Nickel-plated HN for corrosive
  environments: forged brass head and valve
  caps with nickel plating for marine, coastal,
  shipyard, and chemical industrial environments
  where standard brass surfaces
  degrade under sustained exposure
• High-efficiency manifold design:
  optimized internal flow passages for reduced
  turbulence and improved volumetric efficiency
  at 7,250 PSI — the manifold architecture
  that separates the SHP platform from
  standard industrial triplex
  alternatives
• Oversized SKF tapered bearings for
  25 EBHP continuous duty: precision-rated
  for the load combination at this duty point —
  extended bearing service intervals and reduced
  unplanned downtime risk in continuous
  industrial operation
• 1,450 RPM low-speed for
  ultra-high-pressure longevity: controlled
  vibration, managed heat accumulation, and reduced
  packing fatigue — the operating speed that makes
  continuous-duty 7,250 PSI
  service life achievable
• 29-lb compact package for a 25 EBHP
  industrial pump: practical weight for
  skid, trailer, and centralized system
  integration where pump weight
  contributes to total
  system load
• Factory-verified performance at
  7,250 PSI: 100% tested before shipment —
  critical for system builders specifying a
  pump for safety-rated hydrostatic testing
  and industrial blasting
  applications

SHP2050HN Typical Applications

Where 5.3 GPM at 7,250 PSI Delivers Ultra-High-Pressure Industrial Results

• Heavy manufacturing and fabrication
  facilities: large-scale equipment cleaning,
  weld spatter removal, and manufacturing surface
  preparation where 5.3 GPM at 7,250 PSI delivers
  the throughput that production schedules
  require without abrasive media
  or chemical treatments
• Industrial surface preparation and
  coating removal: paint, scale, rust, and
  surface contamination removal prior to recoating,
  lining installation, or structural repair where
  5.3 GPM at 7,250 PSI achieves near-white
  metal surface profiles faster than
  lower-flow alternatives at
  equivalent pressure
• Centralized multi-station cleaning
  systems: industrial facilities supplying
  two or more ultra-high-pressure work points
  simultaneously where 5.3 GPM flow volume
  supports the manifold distribution that
  3.96 GPM alternatives
  cannot serve
• High-pressure cleaning of large
  machinery and infrastructure: industrial
  process equipment, structural steel, bridges,
  and large facility components where maximum
  flow at 7,250 PSI reduces cleaning time
  per shift on large surface
  areas
• Marine and shipyard operations:
  the SHP2050HN’s nickel-plated HN construction
  makes it the correct specification for saltwater
  and marine chemical environments — hull
  preparation, coating removal, and
  corrosion control at
  high throughput
• Industrial wash bays with extreme
  pressure requirements: specialized wash
  bay installations where standard 3,000–4,000 PSI
  pump capability is insufficient for the cleaning
  tasks required — the SHP2050HN delivers
  7,250 PSI at the flow volume
  industrial wash bays need

SHP2050HN Installation & Safety

Critical Requirements for 7,250 PSI Ultra-High-Pressure System Integration

• All system components must be rated
  for 7,250 PSI minimum: hoses, fittings,
  unloaders, safety relief valves, and blasting
  accessories rated below 7,250 PSI are not
  acceptable — component failure at
  ultra-high pressure presents
  serious safety risk
• Size drive system for 25 EBHP at
  1,450 RPM: specify 25+ HP engine or motor
  with appropriate speed reduction to deliver
  1,450 RPM at the 24mm shaft under full
  7,250 PSI operating load — undersized
  power causes speed drop
  and output loss
• Install safety relief valve rated
  for 7,250 PSI: mandatory for every
  SHP2050HN system; unloaders and bypass
  circuits must also be rated
  for full system pressure
• Size inlet plumbing for 5.3 GPM
  with adequate NPSH margin: at 5.3 GPM,
  inlet restriction cavitation is more
  significant than at the SHP1550HN —
  undersized suction plumbing
  accelerates plunger and
  packing damage
• Operator PPE is mandatory:
  ultra-high-pressure water at 7,250 PSI
  causes severe injection injuries —
  appropriate PPE, safe standoff distances,
  and trained operators are required
  for all SHP2050HN
  system operation
• Monitor oil sight glass before
  every shift: at 25 EBHP continuous duty,
  crankcase oil condition and level directly
  determine SKF bearing and plunger
  longevity — never operate with
  low or degraded oil
• First oil change at 50 hours:
  then per AR industrial duty-cycle schedule;
  flush with clean water after every chemical
  or descaling application
• Winterize before cold storage:
  drain completely or use appropriate antifreeze —
  freeze damage to the nickel-plated brass
  manifold voids warranty
