XMA3G18E-F33 Triplex Plunger Pump | 3.0 GPM 1800 PSI

Annovi Reverberi XMA3G18E-F33 Triplex Pump | 3.0 GPM 1800 PSI F33 NEMA 56C 1750 RPM

XMA3G18E-F33 — the Annovi Reverberi Series 178 XMA commercial
triplex plunger pump delivering 3.0 GPM at 1,800 PSI at a
slow-speed 1,750 RPM through an F33 NEMA 56-C flange
and 5/8-inch hollow E-version electric shaft for direct coupling
to standard NEMA 56-C electric motors — engineered for vehicle washing,
residential surface cleaning, outdoor equipment washdown, light commercial
storefronts, and surface preparation where a compact, 15-lb commercial triplex
pump delivers reliable 3.0 GPM performance at 1,800 PSI from a direct electric
motor-driven slow-speed platform. At the heart of every
XMA3G18E-F33 is Annovi Reverberi’s dual redundant
packing system — the forged brass head double gasket sealing architecture
standard across the entire XM Series 178 family, deploying primary and secondary
packing stages so that early seal wear produces a telltale weep warning rather
than sudden pressure loss or crankcase contamination. Backed by a
5-year commercial warranty with AR North America’s nationwide
U.S.-based service centers and domestic WSHPWR fulfillment.

Standard XM Series 178 Package

Every XMA3G18E-F33 Ships Complete — Nothing Extra to Source

Every pump across the AR XM Series 178 family ships with the same standard
factory package: break-in oil pre-filled in the crankcase,
vented dipstick for pressure control and oil level access,
oil sight glass for at-a-glance level checks before each
operating session, direct-drive mounting bolts for F33 NEMA
56-C motor installation, operator’s manual with parts schematic
for installation reference and repair kit identification, and
5-year commercial warranty documentation backed by AR North
America’s nationwide U.S. service center network and
domestic WSHPWR fulfillment.

The AR Dual Redundant Packing System

XMA3G18E-F33 — 60 Years of Longevity Engineering Standard on Every Unit

The dual redundant packing system is standard on every pump
across the AR XM, XMS, XMA, XMV, SXM, SXMS, SXMA, and SXMV triplex ceramic
plunger families. In a standard single-packing design, one seal ring contains
working pressure at every plunger stroke — when it wears, pressure bypasses
immediately, water contaminates the crankcase oil, and bearings accelerate
toward failure without warning. The AR dual redundant system places primary and
secondary packing stages in series. When the primary stage nears end of service
life, the secondary maintains pressure containment while a minor weep at the
telltale port alerts the operator. That early warning converts an unexpected
breakdown into a planned maintenance event — the accumulated result of over
60 years of Annovi Reverberi commercial pump engineering since 1958, and the
confidence behind the 5-year warranty on every XMA3G18E-F33.

XMA3G18E-F33 vs. XMA25G18E-F33 — 3.0 GPM vs. 2.5 GPM at 1,800 PSI

Same Pressure, Same Platform, Same Flange — Flow Volume Is the Decision

The XMA3G18E-F33 and the XMA25G18E-F33 share the same 1,800 PSI
pressure rating, same F33 NEMA 56-C flange, same 5/8-inch E-shaft, and same
Series 178 XMA platform. The difference is flow volume and the EBHP demand
that comes with it.

The XMA3G18E-F33 delivers 3.0 GPM at 4.0 EBHP —
the correct choice when motor capacity supports 4.0 HP at 1,750 RPM and
maximum coverage speed at 1,800 PSI is the priority. The additional 0.5 GPM
over the lower-flow variant produces noticeably faster rinsing on vehicle
surfaces, wider spray patterns on outdoor cleaning tasks, and better carry-off
on residential driveways and patios where the larger flow volume moves
loosened soils more efficiently toward drains.

The XMA25G18E-F33 delivers 2.5 GPM at 3.0 EBHP — the correct
choice for 120V motor packages with tighter power budgets, small wash bays
with limited drain capacity, or compact cart builds where water tank volume
limits operating time. If the motor and installation can support 4.0 EBHP at
1,750 RPM, the XMA3G18E-F33 delivers more cleaning
throughput per session for the same 1,800 PSI output.

XMA3G18E-F33 Key Benefits

Dual Redundant Packing, 1,800 PSI Surface-Safe Output, and 1,750 RPM Slow-Speed Drive

• Dual redundant packing — planned maintenance
  instead of breakdowns: primary and secondary
  stages with telltale port warning; standard on
  every XM Series 178 pump since 1958
• 3.0 GPM at 1,800 PSI — thorough coverage
  at surface-safe pressure: effective on
  vehicles, residential surfaces, and equipment
  without the technique demands of higher-pressure
  systems on sensitive materials
• 1,750 RPM extends every wear interval:
  reduced heat generation, valve cycling, and
  packing fatigue versus 3,400 RPM alternatives
  at equivalent output — the slow-speed advantage
  that compounds across a
  full operating season
• F33 NEMA 56-C 5/8-inch E-shaft — standard
  electric motor interface: fits the most
  common NEMA 56-C motor output shaft without
  adapters; compact direct coupling without
  belts or pulleys
• More flow than the XMA25G18E-F33 at the
  same pressure: 3.0 GPM versus 2.5 GPM
  for faster rinsing and better carry-off when
  the motor supports 4.0 EBHP at 1,750 RPM
• Forged brass manifold and field-serviceable
  valves: maintenance plug access for AR repair
  kit replacement — rebuilt at wear intervals,
  not discarded

XMA3G18E-F33 Typical Applications

Where 3.0 GPM at 1,800 PSI at 1,750 RPM Delivers Results

• Vehicle washing: cars, trucks, RVs,
  motorcycles, and boats where 1,800 PSI delivers
  thorough cleaning without paint or clear coat
  risk — the pressure specification that covers
  the widest range of vehicle
  surfaces safely
• Residential surface cleaning: decks,
  driveways, walkways, siding, and fences where
  3.0 GPM at 1,800 PSI removes surface soils and
  organic growth efficiently without the
  aggression that higher-pressure systems
  require careful technique
  to manage
• Outdoor equipment washdown: lawn
  mowers, tractors, tools, and farm equipment
  where the compact electric direct-drive format
  provides convenient washdown capability from
  a fixed shop or
  barn installation
• Light commercial cleaning: storefronts,
  small machinery, and equipment washdown where
  3.0 GPM at 1,800 PSI covers routine commercial
  cleaning within a standard NEMA 56-C
  electric motor-driven
  installation
• Surface preparation: removing dirt,
  biological growth, and surface buildup prior
  to painting, sealing, or refinishing where
  controlled 1,800 PSI protects the substrate
  being prepared

XMA3G18E-F33 Installation & Maintenance

Best Practices for Long Dual Packing Service Life at 1,750 RPM

• Confirm motor output shaft is 5/8-inch
  and NEMA 56-C face: the XMA3G18E-F33
  F33 E-shaft requires a 5/8-inch motor output
  shaft — 3/4-inch shaft motors require a
  D-version pump
• Confirm motor delivers 1,750 RPM and
  4.0 HP under load: motor undersizing
  causes speed drop and reduces output
  below 1,800 PSI
• Monitor telltale port: minor weep =
  primary packing wear; secondary is holding
  pressure — schedule AR repair kit replacement
  before secondary failure occurs
• Install upstream inlet strainer:
  50-mesh minimum — clean inlet water protects
  both packing stages and ceramic plungers
• Size unloader for 3.0 GPM and
  1,800 PSI: prevents pressure spikes
  that stress the dual packing beyond
  rated load
• Never run dry: confirm water flow
  before starting — dry operation damages both
  packing stages and plungers immediately
  and voids warranty
• First oil change at 50 hours:
  then per AR duty-cycle schedule; flush manifold
  with clean water after every
  chemical application
• Winterize: pump RV antifreeze
  through or fully drain before freezing
  temperatures — freeze damage
  voids warranty
