XMA4G20E-F33 Electric Pump | 4.0 GPM 2000 PSI 1750 RPM

Annovi Reverberi XMA4G20E-F33 Triplex Pump | 4.0 GPM 2000 PSI F33 NEMA 56C 1750 RPM

XMA4G20E-F33 — the Annovi Reverberi Series 178 XMA commercial
triplex plunger pump delivering 4.0 GPM at 2,000 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 fleet and equipment
washing, industrial maintenance wash stations, food processing facility washdown,
manufacturing cleaning systems, and commercial contractor electric rigs where
4.0 GPM high-flow output at 2,000 PSI from a compact, direct motor-driven
slow-speed platform delivers the combination of volume, pressure, and service
life that continuous commercial duty requires. At the heart of every
XMA4G20E-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.

The AR Dual Redundant Packing System

XMA4G20E-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 XMA4G20E-F33.

4.0 GPM at 1,750 RPM — Highest-Flow XMA F33 Electric at Low Speed

More Volume Than the XMA3G25E-F33, Produced at the Same Controlled 1,750 RPM

The XMA4G20E-F33 is the highest-flow pump in the XMA F33
electric family — 4.0 GPM at 2,000 PSI versus the 3.0 GPM / 2,500 PSI of the
XMA3G25E-F33 above it in pressure, and 3.0 GPM / 1,800 PSI of the XMA3G18E-F33
below it. This positioning makes the XMA4G20E-F33 the correct choice when
maximum water volume at controlled 2,000 PSI is the priority over higher
pressure with less flow.

At 4.0 GPM, the XMA4G20E-F33 covers fleet vehicles,
industrial equipment, and food processing surfaces faster per shift than
3.0 GPM alternatives — moving loosened soils toward drains with fewer passes,
supporting more vehicles or equipment through a wash bay per operating hour,
and delivering the high-volume rinsing that food processing and manufacturing
washdown require to meet sanitation protocol timing. The 2,000 PSI working
pressure is effective on industrial surfaces, production equipment, and fleet
vehicles without the surface aggression that higher-pressure specifications
introduce in food processing and manufacturing environments where equipment
surfaces and coatings need protection.

All of this is produced at 1,750 RPM — the slow-speed
advantage that extends dual packing seal intervals, valve wear cycles, and
bearing service life versus the 3,400 RPM alternatives that deliver equivalent
or lower flow at higher speed-induced component fatigue. For industrial
facilities and fleet operations running the XMA4G20E-F33
through daily cleaning cycles, the 1,750 RPM design means predictable
maintenance scheduling that fits operational budgets rather than
emergency component replacement.

XMA4G20E-F33 Key Benefits

Highest-Flow XMA F33, Dual Redundant Packing, and Quiet Low-Speed Direct 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
• 4.0 GPM — highest flow in the XMA F33
  electric family: more volume for faster
  fleet washing, broader industrial coverage,
  and efficient food processing washdown than
  the 3.0 GPM F33 variants at
  equivalent or higher pressure
• 2,000 PSI — effective commercial cleaning
  without surface aggression: correct for
  food processing equipment, manufacturing
  surfaces, and fleet vehicles where
  higher-pressure specifications
  create surface risk
• 1,750 RPM quiet low-speed operation:
  cooler running, lower noise, and reduced
  vibration versus 3,400 RPM alternatives —
  the continuous-duty specification for
  industrial wash stations where
  ambient noise matters
• 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
• Forged brass manifold and field-serviceable
  valves: maintenance plug access for AR repair
  kit replacement — rebuilt at wear intervals,
  not discarded

XMA4G20E-F33 Typical Applications

Where 4.0 GPM at 2,000 PSI at 1,750 RPM Delivers Commercial Results

• Fleet and equipment washing: trucks,
  buses, and service vehicles where 4.0 GPM at
  2,000 PSI delivers faster per-vehicle throughput
  than 3.0 GPM alternatives — more vehicles
  through the wash bay per shift
• Industrial maintenance wash stations:
  factory wash bays and production equipment
  cleaning where 4.0 GPM high-flow output and
  1,750 RPM quiet operation meet both throughput
  and ambient noise requirements
  of industrial facilities
• Food processing facility washdown:
  production floor and equipment cleaning where
  4.0 GPM at 2,000 PSI covers large washdown
  areas efficiently within sanitation protocol
  timing — OEM system builders should follow
  facility certification requirements
  for completed system configurations
• Manufacturing cleaning systems:
  production and assembly environments where
  consistent 4.0 GPM output from a compact
  electric motor-driven platform meets facility
  washdown requirements without
  gas engine exhaust or
  noise concerns
• Commercial contractor electric rigs:
  portable and cart-mounted systems where
  the XMA4G20E-F33’s 4.0 GPM output,
  F33 direct-drive, and 14-lb compact
  weight deliver high-flow commercial
  performance in a
  manageable package

XMA4G20E-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 XMA4G20E-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
  5.5 HP under load: motor undersizing
  causes speed drop and reduces output
  below 2,000 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 — at 4.0 GPM clean inlet
  water is critical; inadequate inlet sizing
  causes cavitation that damages both
  packing stages and
  ceramic plungers
• Size inlet plumbing for 4.0 GPM:
  adequate supply line diameter prevents
  inlet restriction cavitation — more
  important at 4.0 GPM than at
  lower-flow variants
• Size unloader for 4.0 GPM and
  2,000 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
