XWLSS42.15N | 11 GPM 2200 PSI Pump 1450 RPM SS Head 24mm Shaft

Annovi Reverberi XWLSS42.15N Stainless Steel Industrial Pump | 11 GPM 2200 PSI Grade 316

XWLSS42.15N — the Annovi Reverberi Grade 316 stainless steel
industrial triplex plunger pump delivering 11 GPM at 2,200 PSI
at a controlled 1,450 RPM — engineered for food and beverage
processing washdown, meat, seafood, and poultry processing sanitation, agricultural
facility cleaning, fleet and heavy equipment washing, and continuous-duty industrial
environments where caustic cleaning agents, sanitizers, acid solutions, and constant
moisture exposure demand stainless manifold construction over brass. The
XWLSS42.15N is built on a 24 mm solid keyed shaft
compatible with belt-drive, gear-drive, and electric motor flange configurations —
combining a Grade 316 stainless steel manifold head, ceramic plungers, stainless
steel valves, high-grade chemical-resistant seals, and oversized bearings into a
continuous-duty industrial pump backed by a 5-year commercial warranty
with U.S.-based service support.

The XWLSS42.15N sits between the 13.2 GPM XWLSS50.15N and the
12 GPM XWLASS12G22N in the Annovi Reverberi XWL stainless family — the mid-tier
high-flow stainless specification for facilities that require Grade 316 corrosion
resistance and 2,200 PSI continuous-duty output at 11 GPM. Where the XWLSS50.15N’s
13.2 GPM output serves the highest-throughput sanitation lanes and multi-gun
manifold systems, the XWLSS42.15N is sized for single-operator
wash stations, tank and container rinse cycles, chemical wash bays, and
large-equipment sanitation operations where 11 GPM provides thorough coverage
with manageable water recovery demand.

How the XWLSS42.15N Delivers Stainless Industrial Performance

Grade 316 Construction at 1,450 RPM for Chemical-Exposure Continuous Duty

The XWLSS42.15N uses a triplex plunger system where three
ceramic plungers operate in synchronized reciprocation — each cylinder drawing
water through stainless steel inlet valves and discharging at rated 2,200 PSI
through stainless discharge valves in a balanced, overlapping three-cylinder cycle.
This configuration produces smooth, consistent 11 GPM output with substantially
reduced pulsation versus axial or wobble-plate designs at equivalent flow —
protecting downstream hose assemblies, spray bars, and chemical wash manifold
systems from hydraulic fatigue across long industrial sanitation shifts.

The Grade 316 stainless steel manifold head is the specification
that makes the XWLSS42.15N the correct pump for environments that consume brass
manifold pumps prematurely. Grade 316 provides resistance to chloride pitting,
caustic attack, acid exposure, and the accelerated surface degradation that
standard brass and Grade 304 stainless experience in food processing rinse
chemistry, high-pH sanitizer cycles, and saltwater-adjacent environments. For
meat, seafood, and poultry processing plants running aggressive cleaning protocols,
agricultural facilities with animal waste and acid wash exposure, and chemical
rinse stations where manifold longevity has been a recurring maintenance problem,
the XWLSS42.15N provides the chemical resistance that
the application demands.

At 1,450 RPM, the XWLSS42.15N’s ceramic plungers, stainless
valve seats, chemical-resistant seals, and oversized bearings operate at a
controlled rate that maintains stable internal temperatures across the extended
sanitation cycles of food processing and industrial cleaning operations — critical
for facilities where the pump runs continuously across multiple daily cleaning
phases with minimal idle time between cycles.

XWLSS42.15N Key Benefits

Grade 316 Stainless, 11 GPM High Flow, and 1,450 RPM Continuous Duty

XWLSS42.15N Typical Applications

Where Grade 316 Stainless at 11 GPM and 2,200 PSI Is the Right Specification

• Food and beverage processing washdown:
  production floor and equipment sanitation where repeated
  caustic rinse and sanitizer exposure demands the Grade 316
  stainless manifold — OEM machine builders should follow
  facility certification requirements for their
  completed system configurations
• Meat, seafood, and poultry processing plants:
  high-pH cleaning protocols and chloride-bearing sanitizers
  in protein processing environments where the
  XWLSS42.15N’s complete stainless wet end handles
  the chemistry that degrades
  brass manifold pumps
• Agricultural and farm sanitation: livestock
  facilities, barn washdown, and equipment cleaning where
  animal waste acids, manure chemistry, and outdoor moisture
  exposure make Grade 316 stainless the correct manifold
  specification for long service life
• Fleet garages and heavy-equipment washing:
  municipal garages and fleet cleaning programs where
  11 GPM at 2,200 PSI provides fast vehicle coverage
  and the stainless construction handles diverse
  vehicle cleaning chemistry
• Tank, container, and equipment rinse cycles:
  chemical wash bays and industrial rinse stations where
  the XWLSS42.15N’s predictable 11 GPM output at
  2,200 PSI delivers controlled rinse performance
  across repeated cleaning cycles
• Environmental and wastewater service operations:
  cleaning equipment exposed to wastewater chemistry,
  biological residues, and variable chemical conditions
  where Grade 316 stainless provides the corrosion
  tolerance that standard pump materials
  cannot sustain

XWLSS42.15N Installation & Maintenance

Best Practices for Grade 316 Stainless Industrial Pump Service Life

• Select the correct drive interface: confirm
  belt-drive, gear-drive, or electric motor flange
  configuration delivers rated 1,450 RPM to the XWLSS42.15N
  24 mm shaft under operating load — underspeed reduces
  pressure; overspeed accelerates
  component wear
• Use corrosion-resistant mounting hardware:
  in food processing, agricultural, and chemical environments,
  mounting hardware should match the pump’s stainless
  specification — carbon steel hardware corrodes in
  the same conditions the
  XWLSS42.15N is designed for
• Size inlet plumbing for 11 GPM: adequate
  supply line diameter and NPSH margin is critical —
  install a corrosion-resistant strainer appropriate
  for the chemical environment upstream of the
  XWLSS42.15N inlet
• Flush between different chemical applications:
  always flush the XWLSS42.15N with clean water between
  caustic and acid wash cycles — mixed chemistry residue
  in manifold and valve passages accelerates degradation
  even on Grade 316 stainless construction
• Check oil before every shift: sight glass
  for visual confirmation and dipstick for secondary
  verification — adequate crankcase oil is the foundation
  of XWLSS42.15N bearing longevity in continuous
  industrial sanitation operation
• Never run dry: confirm water supply is
  flowing before starting — dry operation at 2,200 PSI
  damages ceramic plunger packings immediately and
  voids warranty coverage
• First oil change at approximately 50 hours:
  then follow Annovi Reverberi’s duty-cycle maintenance
  schedule — intensive food processing and agricultural
  sanitation cycles benefit from more frequent
  oil service intervals
• Winterize with food-safe antifreeze where
  required: confirm antifreeze compatibility with
  facility food safety protocols — drain completely
  where food-safe antifreeze is not acceptable
  for the installation environment
