XMV25G26D-F25 Triplex Plunger Pump | 2.5 GPM 2600 PSI

Annovi Reverberi XMV25G26D-F25 Triplex Pump | 2.5 GPM 2600 PSI F25 Gas Engine Flange

XMV25G26D-F25 — the Annovi Reverberi Series 178 XMV commercial
triplex plunger pump delivering 2.5 GPM at 2,600 PSI at
3,400 RPM with an F25 SAE J609a gas engine flange
and 3/4-inch hollow shaft for direct mounting to horizontal-shaft
gas engines in the 4–8 HP class — engineered for contractor cold-water pressure
washers, small fleet and vehicle washing, rental yard and property maintenance
units, agricultural equipment cleaning, and OEM compact gas engine pressure washer
builds where a proven, lightweight, 15-lb commercial triplex pump mounts directly
to the engine without belts, pulleys, or alignment hardware. At the heart of every
XMV25G26D-F25 is Annovi Reverberi’s dual redundant
packing system — the forged brass head double gasket sealing architecture
that has defined AR’s commercial pump longevity since 1958, deploying primary and
secondary packing stages so that early seal wear produces a telltale weep warning
rather than sudden pressure loss or crankcase contamination.

The dual redundant packing system is standard across every pump in the AR XM,
XMS, XMA, XMV, SXM, SXMS, SXMA, and SXMV triplex ceramic plunger families —
and it is the engineering foundation that supports the 5-year commercial
warranty on every XMV25G26D-F25, backed by AR North
America’s nationwide U.S.-based service centers and domestic WSHPWR fulfillment.
Built with a forged brass manifold, ceramic plungers, aluminum connecting rods,
heat-treated stainless valves, and a die-cast aluminum oil-bath crankcase with
cooling fins, the XMV25G26D-F25 is factory-tested for flow and pressure before
shipment and arrives pre-filled with break-in oil for immediate engine
installation.

The AR Dual Redundant Packing System

XMV25G26D-F25 — The Longevity Architecture Behind 60 Years of AR Commercial Pumps

The dual redundant packing system is the engineering foundation
that separates Annovi Reverberi’s XM Series 178 commercial pumps from standard
single-seal triplex designs — and it is built into every XMV25G26D-F25
as standard specification.

In a standard single-packing design, one seal ring contains working pressure at
every plunger stroke. When that ring wears, pressure bypasses immediately —
the result is output loss, water contamination of the crankcase oil, accelerated
bearing wear, and an unplanned service event that takes the pressure washer
out of service without warning. The AR dual redundant system places primary
and secondary packing stages in series. The primary stage carries the full
sealing load during normal operation. As it reaches the end of its service
life, the secondary stage maintains pressure containment — and a minor weep
at the telltale port alerts the operator before any output degradation occurs.
That early warning converts an unexpected breakdown into a planned maintenance
event that can be scheduled around the work rather than interrupting it.

For contractors running the XMV25G26D-F25 through daily
cleaning schedules, rental yard operators managing pressure washer fleets,
and property maintenance crews who depend on consistent availability, the
practical outcome is longer seal service intervals, predictable maintenance
scheduling, and crankcase oil protection from the contamination events that
single-seal failure causes. This is the accumulated engineering of Annovi
Reverberi’s more than 60 years of commercial pump manufacturing since 1958 —
reflected in a 5-year commercial warranty that competitors with single-seal
designs cannot match and backed by AR North America’s nationwide U.S. service
infrastructure and domestic WSHPWR fulfillment.

What’s Included with the XMV25G26D-F25

Factory-Ready for Immediate Gas Engine Installation

• Factory pre-filled break-in oil (14.5 oz) —
  ready for immediate engine mounting without sourcing
  initial oil fill separately
• Integrated oil sight glass — quick visual
  crankcase level check before each operating
  session
• F25 flange mounting hardware — for secure
  square engine-to-pump alignment on SAE J609a
  compatible engines
• Factory performance verification —
  2.5 GPM and 2,600 PSI output confirmed before
  every XMV25G26D-F25 shipment
• 5-year commercial warranty — backed by
  nationwide U.S.-based AR service centers and
  domestic WSHPWR fulfillment; parts, service, and
  warranty claims resolved domestically without
  international sourcing delays

XMV25G26D-F25 Performance and Sizing

Matching the Right Engine and System Components to 2.5 GPM at 2,600 PSI

• Engine horsepower requirement — 4.7 EBHP:
  pair the XMV25G26D-F25 with a quality 5–6.5 HP gas
  engine for reliable operation with adequate power
  margin — undersized engines cause RPM drop
  under load and premature
  wear at 3,400 RPM
• Match governed engine speed to 3,400 RPM:
  verify engine governed speed matches the
  XMV25G26D-F25’s rated 3,400 RPM — over-speeding
  accelerates wear on the dual packing, plungers,
  and bearings; under-speeding reduces
  pressure output
• Unloader or regulator required: always
  operate the XMV25G26D-F25 with a properly sized
  unloader or regulator — without pressure regulation,
  trigger release events create pressure spikes
  that stress the dual packing
  beyond rated load
• Bypass plumbing to supply tank: route
  bypass water to the supply tank or pump inlet
  with adequate volume — extended bypass periods
  without proper routing allow heat buildup that
  shortens packing
  service life
• F25 compatible engine list: the F25 SAE
  J609a flange fits most horizontal-shaft gas engines
  in the 4–8 HP class with 3/4-inch cylindrical
  shaft — confirm engine shaft diameter and
  bolt pattern before installation

XMV25G26D-F25 Key Benefits

Dual Redundant Packing, Forged Brass, and F25 Direct Gas Drive

• Dual redundant packing converts breakdowns to
  planned maintenance: the AR engineering standard
  that contractors and rental yard operators
  recognize after experiencing single-seal pump
  failures — standard on every
  XMV25G26D-F25
• 2,600 PSI from a 15-lb compact package:
  the commercial triplex output that fits contractor
  cart frames, consumer pressure washer housings,
  and OEM compact builds that larger pumps
  cannot accommodate
• F25 SAE J609a direct mount — no belts, no
  pulleys: bolt directly to compatible
  horizontal-shaft gas engines for a compact,
  vibration-reduced drive package that eliminates
  belt wear, pulley alignment, and the mechanical
  energy loss of indirect
  drive systems
• Forged brass manifold for commercial service
  life: superior structural integrity and
  corrosion resistance versus cast brass at 2,600 PSI
  repeated pressurization — the manifold specification
  that extends pump service life in contractor
  and rental fleet applications
• Heat-treated stainless valves with maintenance
  plugs: field-serviceable without removing the
  manifold — repair kit valve replacement at wear
  intervals keeps the XMV25G26D-F25 performing
  like new without full
  pump replacement
• Cooling fins for 3,400 RPM sustained
  operation: die-cast aluminum crankcase
  cooling fins manage heat at direct gas drive
  speed — practical thermal management for
  contractor daily use and
  rental fleet operation
• Right-hand horizontal orientation for easy
  installation: designed to align naturally with
  common engine output shafts and standard mounting
  rails without repositioning hardware on
  typical pressure washer
  frame configurations
• 5-year warranty backed by U.S.
  infrastructure: the strongest warranty in
  the compact gas engine pump class — AR North America
  nationwide service centers and domestic WSHPWR
  fulfillment mean support is
  always domestic

XMV25G26D-F25 Typical Applications

Where 2.5 GPM at 2,600 PSI on F25 Gas Engine Delivers Commercial Results

• Contractor cold-water pressure washers:
  siding, decks, driveways, walkways, and jobsite
  cleanup at light-to-medium duty cycles — the
  XMV25G26D-F25’s 2,600 PSI output handles the
  full range of standard contractor
  cleaning tasks efficiently
• Small fleet and vehicle washing: pickup
  trucks, trailers, service vehicles, and light
  equipment where 2.5 GPM at 2,600 PSI provides
  thorough cleaning without requiring the larger
  engine platforms of
  higher-flow alternatives
• Rental yard and hardware-store pressure
  washer fleets: the XMV25G26D-F25’s dual
  redundant packing and field-serviceable valve
  design make it an ideal replacement and OEM pump
  for rental fleets where uptime and
  predictable maintenance scheduling
  are operational requirements
• Facility and property maintenance:
  apartment complexes, campuses, hotels, and light
  industrial facilities where consistent washdown
  capability from a compact gas engine system
  serves regular maintenance schedules
• Agricultural and farm use: small tractors,
  implements, pens, and equipment cleaning where
  the XMV25G26D-F25’s 15-lb compact weight and
  F25 direct-mount make it practical for farm
  equipment installations in the
  5–6.5 HP engine class
• OEM and custom pressure washer builds:
  compact mobile washers and custom skid units
  powered by 4–8 HP horizontal-shaft engines where
  the XMV25G26D-F25’s weight, footprint, and
  F25 direct-drive provide the most efficient
  pump-to-engine
  integration

XMV25G26D-F25 Installation & Maintenance

Best Practices for Long Dual Packing and Engine Drive Service Life

• Verify F25 SAE J609a engine compatibility:
  confirm the engine has a 3/4-inch cylindrical shaft
  and SAE J609a bolt pattern before mounting —
  incorrect shaft diameter or non-standard bolt
  pattern prevents proper F25
  flange engagement
• Mount square and aligned: use the
  integrated F25 flange with proper engine bolts;
  ensure engine and pump are perfectly square to
  prevent shaft wear, crankcase stress, and
  premature bearing failure at
  3,400 RPM
• Monitor the telltale port: a minor weep
  indicates primary packing wear — the secondary
  is maintaining pressure; schedule seal replacement
  using AR repair kits promptly rather than running
  to secondary
  packing failure
• Install upstream inlet filtration: size
  suction plumbing and strainer for 2.5 GPM with
  minimal pressure drop — clean inlet water protects
  the dual packing seals and ceramic plungers from
  abrasive contamination
• Never run dry: always confirm water
  supply is flowing before starting the engine —
  dry operation at 3,400 RPM damages both packing
  stages and ceramic plungers immediately
  and voids warranty
• First oil change at 50 hours: then
  follow AR’s recommended service interval —
  contractor daily use and rental fleet operation
  benefit from more frequent changes than
  occasional residential use
• Downstream inject detergents: always
  inject cleaning agents downstream of the pump
  or thoroughly flush with clean water after every
  chemical application to protect the forged brass
  manifold and dual packing
  seals from chemical residue
• Route bypass correctly: direct bypass
  water to the supply tank or pump inlet —
  extended trigger-off periods without proper
  bypass routing build heat that shortens
  packing service life at
  3,400 RPM
• Service valves with AR repair kits:
  as hours accumulate, refresh water seals, oil seals,
  and stainless valves using genuine AR kits —
  the maintenance plug valve access on the
  XMV25G26D-F25 makes
  this practical in the field
• Winterize before cold storage: pump
  environmentally friendly or RV antifreeze through
  the system or fully drain pump and lines — freeze
  damage to the forged brass manifold
  voids warranty coverage
