XMASS1G15E-F33-B 1.0 GPM 1500 PSI Pump | Buna Seals 1750 RPM

Annovi Reverberi XMASS1G15E-F33-B Stainless Triplex Pump | 1.0 GPM 1500 PSI Buna-N F33 56C

XMASS1G15E-F33-B — the Annovi Reverberi forged stainless steel
compact triplex plunger pump delivering 1.0 GPM at 1,500 PSI at
1,750 RPM with a NEMA 56C F33 direct-drive flange
and Buna-N seals — engineered for component wash stations, robotic
rinse modules, food service and beverage equipment cleaning, agricultural spraying
systems, automotive detailing, and compact OEM integrations where stainless manifold
corrosion resistance, direct 56C motor coupling, and Buna-N compatibility with
water-based detergents and rinse agents deliver dependable daily performance in a
space-efficient package. The XMASS1G15E-F33-B is the Buna-N seal
variant of the XMA stainless electric family — the correct specification when
stainless manifold durability and F33 direct-drive integration are required but
the application chemistry is water-based detergents, rinse agents, and light
solvents that fall within Buna-N compatibility rather than the aggressive
sanitizers and concentrated process chemicals that require Viton seals.

The XMASS1G15E-F33-B combines a forged stainless steel manifold,
precision ceramic plungers, stainless steel inlet and discharge valves, a die-cast
aluminum oil-bath lubricated crankcase, and oversized crankshaft bearings into a
compact 56C direct-drive package that eliminates belt drive assemblies, minimizes
vibration, and fits enclosed OEM assemblies, bench-mounted cleaning stations, and
mobile skid units where space efficiency and mechanical simplicity are both
operating requirements. Every XMASS1G15E-F33-B ships factory performance-tested
for flow and pressure, pre-filled with break-in oil, and backed by a
5-year commercial warranty.

XMASS1G15E-F33-B vs. XMASS1G15E-F33 — Choosing the Right Seal

Buna-N for General Wash Chemistry, Viton for Aggressive Sanitizers

The XMASS1G15E-F33-B and the XMASS1G15E-F33 are the same pump
platform — same AISI 316 stainless manifold, same F33 56C direct-drive, same
1.0 GPM at 1,500 PSI at 1,750 RPM. The single specification difference is the
seal material, and that difference determines which applications each pump
is correct for.

Buna-N seals in the XMASS1G15E-F33-B provide excellent
compatibility with water-based detergents, rinse agents, light solvents,
and the general wash chemistry used in food service equipment cleaning,
component wash stations, agricultural spraying, and automotive detailing.
Buna-N is the correct seal specification for these applications — it provides
long service life in water-based chemistry and does not require the premium
cost of Viton for applications that don’t demand it.

Viton seals in the XMASS1G15E-F33 are the correct specification
when the application involves concentrated pharmaceutical sanitizers, aggressive
process chemicals, high-pH caustic agents, or biotech cleaning compounds where
Buna-N seal integrity cannot be guaranteed across the full chemical exposure
range. If the cleaning chemistry includes concentrated sanitizers, CIP chemicals,
or aggressive process compounds, specify the XMASS1G15E-F33 with Viton seals.
If the application is water-based detergents and general rinse chemistry, the
XMASS1G15E-F33-B with Buna-N delivers equivalent stainless
manifold performance at the correct seal specification for the application.

How the XMASS1G15E-F33-B Works

Triplex Plunger and Oil-Bath Crankcase for Compact Direct-Drive Performance

The XMASS1G15E-F33-B uses a triplex plunger design where three
precision-ground ceramic plungers operate in synchronized reciprocation — drawing
water through stainless steel inlet valves and discharging at rated 1,500 PSI
through stainless discharge valves in a balanced overlapping three-cylinder cycle.
High-efficiency valve and plunger alignment reduces vibration for quiet operation
in enclosed cabinet and bench-mounted installations where noise level is a
working environment consideration.

The F33 flange mount aligns the XMASS1G15E-F33-B directly with
56C-style electric motors at 1,750 RPM — no belts, no pulleys, no alignment
procedures beyond standard motor coupling. Direct drive eliminates belt slip,
reduces mechanical energy loss, and produces the compact motor-to-pump footprint
that OEM assemblies and mobile skid units require when space
efficiency is a design constraint.

The die-cast aluminum oil-bath crankcase continuously coats
bearings and connecting rods throughout operation — at 1,750 RPM the oil-bath
system provides reliable lubrication film coverage that splash lubrication
methods cannot maintain consistently under continuous direct-drive operating
conditions. Die-cast aluminum’s thermal conductivity helps manage crankcase
temperature during extended duty cycles in enclosed
cabinet installations.

XMASS1G15E-F33-B Key Benefits

Forged Stainless, Buna-N, and F33 Direct-Drive for General Wash Applications

• Forged stainless manifold at general wash
  pricing: stainless corrosion resistance and
  pitting protection for detergent-rich and moisture-heavy
  environments without the Viton seal premium cost
  when application chemistry is
  water-based
• Buna-N — the correct seal for the application:
  water-based detergents, rinse agents, and light solvents
  are Buna-N compatible — specifying Viton where Buna-N
  performs correctly adds cost without
  adding service benefit
• F33 56C direct-drive eliminates belt complexity:
  direct motor coupling at 1,750 RPM for the cleanest
  possible OEM panel, bench-mounted station, and
  compact skid integration without belt
  maintenance or alignment procedures
• Quiet balanced operation for enclosed
  installations: high-efficiency valve and plunger
  alignment reduces vibration and noise — important in
  bench-mounted stations, automated machine cells, and
  OEM assemblies where operational
  noise matters
• Oil-bath lubrication for continuous direct-drive
  protection: continuous bearing and connecting
  rod film coverage at 1,750 RPM in the die-cast
  aluminum crankcase — more reliable than splash
  lubrication in sustained
  duty cycles
• Drain plug simplifies maintenance in tight
  spaces: accessible crankcase drain in compact
  installations where standard oil change procedures
  require dedicated access points in
  space-constrained OEM builds
• Factory performance-validated output:
  1.0 GPM at 1,500 PSI confirmed before shipment —
  consistent output specification for OEM system
  builders with documented
  performance requirements
• 5-year warranty on forged stainless
  Buna-N construction: exceptional coverage
  for a compact precision pump — backed by
  U.S.-based service support

XMASS1G15E-F33-B Typical Applications

Where Forged Stainless, Buna-N Seals, and F33 Direct-Drive Deliver Results

• Component wash stations and robotic rinse
  modules: the XMASS1G15E-F33-B’s controlled
  1.0 GPM output, direct 56C coupling, and compact
  footprint make it the correct pump for automated
  machine-mounted cleaning modules requiring precise
  RPM control and
  consistent flow
• Food service and beverage equipment cleaning:
  water-based detergent chemistry in food service
  environments where stainless manifold construction
  and Buna-N seal compatibility cover the
  application requirements without
  Viton premium specification
• Agricultural spot spraying and chemical
  application: water-based agricultural chemistry
  and fertilizer solutions within Buna-N compatibility
  range where the XMASS1G15E-F33-B’s compact
  direct-drive design fits
  mobile spraying systems
• Automotive detailing and tool washing:
  detailing chemistry, equipment rinse, and general
  workshop cleaning where 1.0 GPM at 1,500 PSI
  delivers targeted cleaning without overspray
  and the stainless manifold handles
  wash chemical exposure
• Manufacturing clean-in-place functions:
  compact manufacturing cells requiring high-pressure
  CIP functions where the XMASS1G15E-F33-B’s
  forged stainless construction and direct 56C
  mount fit automated process
  equipment builds
• Compact pressure washer builds and OEM
  integrations: enclosed cabinet, wall panel,
  and mobile skid installations where the
  XMASS1G15E-F33-B’s compact footprint,
  stainless manifold, and F33 direct-drive
  deliver space-efficient stainless
  pump performance

XMASS1G15E-F33-B Installation & Maintenance

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

• Verify NEMA 56C motor compatibility: confirm
  the motor uses a 56C face configuration before mounting
  the XMASS1G15E-F33-B — the F33 flange is specifically
  engineered for this standard motor
  interface
• Confirm chemical compatibility with Buna-N
  seals: verify all detergents, rinse agents,
  and process chemicals fall within Buna-N compatibility
  at actual concentration and temperature before
  commissioning — if the application involves
  concentrated sanitizers or aggressive process
  chemicals, specify XMASS1G15E-F33
  with Viton seals instead
• Install fine oversized inlet filtration:
  at 1.0 GPM flow demand, short unrestricted suction
  lines and fine filtration are critical — cavitation
  at low flow damages ceramic plungers and
  Buna-N seals rapidly
• Match nozzle to 1.0 GPM and 1,500 PSI target:
  size nozzle orifice correctly and install a pressure
  gauge at the tool — incorrect nozzle sizing creates
  pressure hunting in precision
  rinse applications
• Size unloader for 1,500 PSI and limit bypass
  cycles: control heat rise by limiting extended
  bypass periods — add thermal relief protection
  appropriate for the XMASS1G15E-F33-B
  installation’s duty cycle
• Prime before every start: flow clean water
  through the XMASS1G15E-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: the accessible
  drain plug simplifies crankcase maintenance in
  compact OEM installations where standard
  drain positioning is not practical
• Flush after every chemical application: run
  clean water through the XMASS1G15E-F33-B after each
  chemical service session to protect manifold passages
  and valve seats from
  residue buildup
