Annovi Reverberi XMASS4G20E-F33 Stainless Triplex Pump | 4.0 GPM 2000 PSI NEMA 56C Viton

XMASS4G20E-F33 — the Annovi Reverberi Series 178 XMA stainless
steel triplex plunger pump delivering 4.0 GPM at 2,000 PSI at
1,750 RPM with a NEMA 56C F33 direct-drive flange
and 5/8-inch hollow shaft — engineered for commercial wash
stations, electric pressure washer systems, portable cleaning carts, equipment
and parts cleaning stations, and enclosed industrial wash systems where stainless
manifold corrosion resistance, Viton o-ring chemical compatibility, and direct
56C motor coupling deliver reliable 4.0 GPM high-flow performance in a compact
17-lb package. At the heart of every XMASS4G20E-F33 is Annovi
Reverberi’s dual redundant packing system — the cornerstone of
AR’s pump longevity engineering, combining primary and secondary packing rings
that share the sealing load at 2,000 PSI so that when the primary seal begins
to show wear, the secondary maintains pressure containment and gives operators
a warning interval rather than a sudden catastrophic failure.

The dual redundant packing system is not an optional feature — it is the standard
specification on every pump in the AR XM, XMS, XMA, XMV, SXM, SXMS, SXMA, and
SXMV triplex ceramic plunger pump families, reflecting over 60 years of Annovi
Reverberi engineering accumulated since 1958. Combined with the
XMASS4G20E-F33’s stainless head, Viton o-rings, ceramic
plungers, and 1,750 RPM low-speed design, this packing system is why AR pumps
routinely achieve thousands of trouble-free operating hours in commercial and
industrial cleaning applications — and why every XMASS4G20E-F33 is backed by
a 5-year commercial warranty with nationwide U.S.-based service
centers and domestic fulfillment.

The AR Dual Redundant Packing System

XMASS4G20E-F33 — 60 Years of Longevity Engineering in Every Pump

The dual redundant packing system is the technical foundation
of Annovi Reverberi’s commercial pump longevity reputation — and it is standard
on every pump across the XM, XMS, XMA, XMV, SXM, SXMS, SXMA, and SXMV
triplex ceramic plunger families including the
XMASS4G20E-F33.

Standard single-packing pump designs rely on one seal ring to contain working
pressure at every plunger stroke. When that ring begins to wear, pressure
bypasses it immediately — the result is sudden output loss, water in the
crankcase, and an unplanned service event. The AR dual redundant system
deploys primary and secondary packing rings in series. The primary ring
carries the full sealing load during normal operation. When it begins to show
wear, the secondary ring maintains pressure containment — and the operator
typically notices a minor weep at the telltale port before any output
degradation occurs. That early warning interval is what converts an unexpected
breakdown into a planned maintenance event.

For commercial operators running the XMASS4G20E-F33 through
daily cleaning shifts, the practical outcome of the dual redundant system is
longer seal service intervals, predictable maintenance scheduling, and
protection of the crankcase and bearings from the water contamination that
single-seal failure events cause in less sophisticated pump designs. This is
the engineering that has made AR pumps the reference standard in commercial
and industrial cleaning markets across over 60 years and in over 100 countries
— and it is the engineering that supports the confidence behind the
5-year commercial warranty on every XMASS4G20E-F33.

XMASS4G20E-F33 Key Benefits

Dual Redundant Packing, Stainless Viton, and F33 Direct-Drive

• Dual redundant packing — the AR longevity
  standard: primary and secondary packing rings
  in series at 2,000 PSI provide the early warning
  interval that converts unexpected breakdowns into
  planned maintenance events — standard on every
  XMASS4G20E-F33 and every pump in the
  XM family
• 4.0 GPM — highest-flow XMA stainless F33
  electric variant: maximum flow at the
  2,000 PSI stainless specification for commercial
  wash stations, parts cleaning, and equipment
  washdown where throughput per shift
  drives productivity
• Stainless head with Viton o-rings — complete
  chemical wet-end specification: the stainless
  series default delivers both manifold corrosion
  resistance and Viton chemical seal compatibility
  for the detergents, sanitizers, and cleaning
  agents of commercial and industrial
  washdown environments
• 1,750 RPM slow-speed design extends component
  life: lower heat, reduced vibration, and
  slower seal cycling than 3,400 RPM direct-drive
  alternatives at equivalent output — every hour
  at 1,750 RPM adds to the service life advantage
  of the dual redundant
  packing system
• F33 NEMA 56C direct-drive in 17 lbs:
  compact direct motor coupling eliminates belt
  hardware in portable carts, enclosed panels, and
  OEM equipment builds where total system weight
  and footprint are both
  design constraints
• Cooling fins for extended duty cycles:
  die-cast aluminum crankcase with cooling fins
  manages heat during 4.0 GPM continuous operation
  in commercial wash stations and
  industrial cleaning installations
• 5-year warranty backed by U.S. infrastructure:
  nationwide AR service centers and domestic
  WSHPWR fulfillment mean warranty claims,
  replacement parts, and technical support are
  resolved domestically — no international
  sourcing delays for
  commercial operators
• 60 years of AR engineering behind every
  unit: Annovi Reverberi has manufactured
  precision triplex pumps since 1958 — the
  XMASS4G20E-F33 is the current expression of
  that accumulated engineering
  expertise

XMASS4G20E-F33 Typical Applications

Where 4.0 GPM at 2,000 PSI With Stainless Viton Dual Packing Delivers Results

• Commercial wash stations and rinse bays:
  4.0 GPM at 2,000 PSI from a stainless Viton pump
  with dual redundant packing covers the full range
  of commercial wash station cleaning demands with
  the chemical resistance and
  service life the application requires
• Electric pressure washer systems:
  the XMASS4G20E-F33’s F33 NEMA 56C direct-drive
  makes it the correct replacement and upgrade pump
  for electric pressure washer systems where stainless
  construction and Viton seals are
  specified requirements
• Portable cleaning carts and skid-mounted
  units: 17-lb compact weight and direct motor
  coupling keep cart and skid system weight and
  footprint practical — the highest XMA stainless
  F33 flow in the most
  portable package
• Equipment and parts cleaning stations:
  consistent 4.0 GPM at 2,000 PSI for industrial
  parts cleaning where stainless construction handles
  cleaning agent chemistry across continuous
  daily wash cycles
• Indoor and enclosed wash systems:
  zero exhaust electric direct-drive with stainless
  Viton construction for enclosed facilities where
  chemical exposure, moisture cycling, and air
  quality are all
  operating considerations
• OEM equipment integrations: compact
  footprint, direct 56C coupling, stainless manifold,
  and factory-verified output make the XMASS4G20E-F33
  a reliable specification for OEM machine builders
  requiring a consistent high-flow
  stainless pump platform

XMASS4G20E-F33 Installation & Maintenance

Best Practices for Long Dual Packing Service Life

• Verify NEMA 56C motor compatibility: confirm
  the electric motor has a 5/8-inch output shaft and
  NEMA 56C face before mounting — the F33 flange is
  engineered specifically for
  this motor standard
• Install fine inlet filtration: size suction
  plumbing and strainer for 4.0 GPM with minimal
  pressure drop — cavitation at this flow rate
  accelerates wear on the dual redundant packing
  and ceramic plungers
• Monitor the telltale port: a minor weep
  at the telltale indicates primary packing wear —
  the secondary is maintaining pressure; schedule
  seal replacement promptly rather than continuing
  to run until secondary
  failure occurs
• Prime before every start: flow clean water
  through the XMASS4G20E-F33 before each session —
  dry running damages both packing rings and ceramic
  plungers simultaneously and voids
  warranty coverage
• Size unloader for 4.0 GPM and 2,000 PSI:
  correctly rated unloader prevents pressure exceedances
  that stress the dual packing system beyond
  its design envelope
• Check oil before every shift: sight glass
  visual confirmation before starting — 14.5 oz
  crankcase; adequate oil is the foundation of
  bearing longevity at 1,750 RPM
  continuous duty
• Never run dry: always confirm water supply
  is flowing before starting — dry operation
  damages both packing stages and
  voids warranty
• First oil change at approximately 50 hours:
  then follow AR duty-cycle maintenance schedule —
  commercial daily-use benefits from more frequent
  intervals than intermittent
  residential use
• Flush after chemical applications: run
  clean water through the XMASS4G20E-F33 after every
  chemical application to protect stainless manifold
  passages and valve seats
• Contact WSHPWR for warranty and service:
  all warranty claims, service parts, and technical
  support are handled domestically through WSHPWR
  and AR North America’s nationwide
  U.S. service network
