Annovi Reverberi XMASS35G15E-F33-B Stainless Triplex Pump | 3.5 GPM 2000 PSI Buna-N F33 56C

XMASS35G15E-F33-B — the Annovi Reverberi Series 178 XMA stainless
steel triplex plunger pump delivering 3.5 GPM at 2,000 PSI at
1,750 RPM with a NEMA 56C F33 direct-drive flange
and Buna-N seals — engineered for car wash systems, parts washers,
food service and sanitation operations, mobile cleaning rigs, industrial equipment
washdown, surface preparation, and agricultural cleaning where stainless manifold
corrosion resistance, F33 direct electric motor coupling, and Buna-N compatibility
with water-based detergents and mild cleaning agents deliver reliable performance
in a compact 17-lb package. The XMASS35G15E-F33-B is the Buna-N
seal variant of the XMA stainless F33 electric family — the correct specification
when stainless manifold durability and 3.5 GPM flow at 2,000 PSI are required
with water-based detergents and cleaning solutions that fall within Buna-N
seal compatibility.

The XMASS35G15E-F33-B delivers the highest flow rate in the
XMA stainless F33 electric family at 3.5 GPM — more volume for faster rinsing,
wider surface coverage, and efficient carry-off than the 3.0 GPM, 2.5 GPM, and
2.0 GPM variants in the same platform family. At 2,000 PSI, the XMASS35G15E-F33-B
provides serious cleaning force for car wash operations, equipment washdown, and
industrial surface preparation without requiring the chemical compatibility
premium of Viton seals when application chemistry is water-based detergents,
mild chemicals, and general cleaning agents within Buna-N’s
compatibility range.

How the XMASS35G15E-F33-B Works

Triplex Plunger and Oil-Bath Crankcase for Smooth High-Flow Electric Performance

The XMASS35G15E-F33-B uses a triplex plunger design where three
solid ceramic plungers produce smooth hydraulic motion in a synchronized
reciprocating sequence — drawing water through stainless steel inlet valves and
discharging at rated 2,000 PSI through stainless discharge valves in a balanced
three-cylinder cycle. The triplex geometry produces a smooth, linear pressure
curve without pressure spikes, and low pulsation output reduces vibration
transmitted to connected hoses, nozzles, and spray gun accessories
across long operating sessions.

The die-cast aluminum crankcase with cooling fins is a practical
thermal management feature for the XMASS35G15E-F33-B’s 3.5 GPM continuous-duty
output — the cooling fins increase surface area for heat dissipation during
extended operating sessions while the oil-bath lubrication system continuously
coats the crankshaft, bearings, and connecting rods throughout operation. At
1,750 RPM the oil-bath system provides reliable film coverage that maintains
consistent lubrication across the full operating shift.

The forged stainless steel head resists the scaling, oxidation,
and waterborne contaminant exposure of car wash environments, parts washing
operations, and general commercial cleaning applications — maintaining internal
sealing tolerances and manifold dimensional stability across the thermal cycling
of frequent daily cleaning sessions that would accelerate brass manifold
degradation in similar applications.

The F33 NEMA 56C direct-drive flange couples the
XMASS35G15E-F33-B directly to compatible electric motors at 1,750 RPM —
no belts, no pulleys, and no external adapters. Perfect alignment is
maintained between motor shaft and pump input, reducing the vibration
and misalignment-induced wear that belt-drive configurations
accumulate over time in commercial
daily-use installations.

XMASS35G15E-F33-B vs. XMASS3G15E-F33 — Flow and Seal Selection

3.5 GPM Buna-N vs. 3.0 GPM Viton — Choosing the Right Configuration

The XMASS35G15E-F33-B and the XMASS3G15E-F33 share the same
XMA stainless F33 electric platform. Two differences define which is correct
for a given application.

Flow: the XMASS35G15E-F33-B delivers 3.5 GPM versus the
3.0 GPM of the Viton variant — 0.5 GPM additional flow for faster surface
coverage and carry-off in car wash lanes, equipment washdown stations, and
agricultural cleaning operations where throughput per shift matters.

Seal material: Buna-N in the XMASS35G15E-F33-B for
water-based detergents and mild cleaning chemistry; Viton in the
XMASS3G15E-F33 for concentrated pharmaceutical sanitizers, aggressive
process chemicals, and high-pH caustic agents. If the application involves
water-based detergents, car wash chemistry, mild industrial cleaners, and
general rinse agents — the XMASS35G15E-F33-B with Buna-N
and 3.5 GPM is the correct specification. If the chemistry includes
concentrated sanitizers or aggressive process compounds — specify the
XMASS3G15E-F33 with Viton seals instead.

XMASS35G15E-F33-B Key Benefits

Highest-Flow XMA Stainless F33 Electric — Forged SS, Buna-N, Direct Drive

• 3.5 GPM — highest flow in the XMA stainless F33
  electric family: more volume for faster rinsing,
  wider spray coverage, and better carry-off than the
  3.0 GPM, 2.5 GPM, and 2.0 GPM variants in the
  same platform family at
  equivalent pressure
• Forged stainless head at the car wash and
  general wash budget: stainless corrosion and
  scale resistance in detergent-rich and moisture-heavy
  environments without the Viton seal premium when
  application chemistry is water-based and
  within Buna-N compatibility
• Buna-N — correct seal for general wash
  chemistry: water-based detergents, car wash
  chemistry, mild industrial cleaners, and agricultural
  cleaning agents are Buna-N compatible — specifying
  Viton where Buna-N performs correctly adds cost
  without adding service benefit
• Cooling fins for extended duty cycles:
  the die-cast aluminum crankcase cooling fins manage
  heat during 3.5 GPM continuous operation — practical
  thermal management for car wash lanes and industrial
  washdown stations that run extended
  daily sessions
• F33 direct-drive eliminates belt maintenance:
  direct NEMA 56C motor coupling at 1,750 RPM for the
  cleanest OEM panel, mobile cart, and compact skid
  integration without belt hardware
  or alignment procedures
• Low-pulsation triplex output protects
  accessories: smooth pressure curve reduces
  vibration transmitted to hoses, nozzles, and spray
  guns — extending accessory service life across
  high-cycle car wash and industrial
  cleaning operations
• 2,000 PSI serious cleaning force for
  commercial applications: effective mechanical
  cleaning on vehicle surfaces, equipment residues,
  and agricultural soils that
  1,500 PSI alternatives
  address more slowly
• Factory-tested flow, pressure, and sealing
  integrity: every XMASS35G15E-F33-B verified
  to specification before shipment — consistent output
  for system builders and OEM
  equipment integrators
• 5-year warranty on forged stainless
  Buna-N construction: exceptional coverage
  for a high-flow compact stainless pump — backed
  by U.S.-based service support

XMASS35G15E-F33-B Typical Applications

Where 3.5 GPM at 2,000 PSI With Forged Stainless and Buna-N Delivers Results

• Car wash systems: the XMASS35G15E-F33-B’s
  3.5 GPM at 2,000 PSI and forged stainless head handle
  car wash detergent chemistry efficiently — Buna-N
  compatibility covers the water-based detergents and
  rinse agents of car wash operations with
  the highest flow rate in the
  XMA stainless F33 family
• Parts washers: consistent 3.5 GPM output
  at 2,000 PSI for industrial parts cleaning where
  stainless construction handles detergent and cleaning
  agent exposure across continuous
  daily wash cycles
• Food service and commercial sanitation:
  stainless manifold and Buna-N seals handle water-based
  food service cleaning chemistry — OEM system builders
  should follow facility certification requirements
  for completed
  system configurations
• Mobile cleaning rigs and portable
  washdown units: 17-lb weight and F33 direct-drive
  keep mobile cart and portable rig weight practical
  — the XMASS35G15E-F33-B delivers the highest
  XMA stainless F33 flow in a
  compact portable package
• Industrial cleaning and manufacturing
  facilities: equipment washdown, shop floor
  cleaning, and maintenance stations where stainless
  construction and 3.5 GPM flow at 2,000 PSI handle
  general industrial cleaning chemistry
  efficiently per shift
• Surface preparation and agricultural
  cleaning: equipment wash stations and
  agricultural machinery cleaning where the
  XMASS35G15E-F33-B’s 3.5 GPM at 2,000 PSI covers
  large surfaces efficiently with Buna-N
  compatibility for agricultural
  cleaning chemistry

XMASS35G15E-F33-B Installation & Maintenance

Best Practices for Compact Stainless Buna-N Direct-Drive Systems

• Verify NEMA 56C motor compatibility: confirm
  the electric motor has a 5/8-inch output shaft and NEMA
  56C face configuration before mounting the
  XMASS35G15E-F33-B
• Confirm Buna-N chemical compatibility: verify
  all detergents and cleaning agents are within Buna-N
  compatibility at actual concentration and temperature
  before commissioning — if application involves
  concentrated sanitizers or aggressive process
  chemicals, specify the Viton seal
  variant instead
• Install fine inlet filtration: size suction
  plumbing and strainer for 3.5 GPM with minimal pressure
  drop — cavitation at this flow rate damages ceramic
  plungers and Buna-N seals and
  voids warranty coverage
• Size nozzle for 3.5 GPM and 2,000 PSI:
  match nozzle orifice to the rated duty point —
  incorrect nozzle sizing creates pressure hunting
  in continuous cleaning applications
• Size unloader for 3.5 GPM and 2,000 PSI:
  limit extended bypass cycles to control heat rise —
  the cooling fins help during operation but bypass
  heat management remains important in
  extended idle periods
• Prime before every start: flow clean water
  through the XMASS35G15E-F33-B before operating —
  dry running damages Buna-N seals and ceramic plunger
  packings immediately and voids
  warranty coverage
• Use drain plug for oil changes: accessible
  drain plug simplifies crankcase oil changes in
  compact installations — first change at
  approximately 50 hours then per
  duty-cycle schedule
• Flush after chemical applications: run
  clean water through the XMASS35G15E-F33-B after
  every cleaning chemical application to protect
  stainless manifold passages and
  valve seats
• Winterize before cold storage: drain
  completely or use pump-safe antifreeze — freeze
  damage voids warranty coverage
