XWLSS50.15N | 13.2 GPM 2200 PSI Pump 1450 RPM SS Head 24mm Shaft

XWLSS50.15N Stainless Steel Industrial Pump | 13.2 GPM 2200 PSI Grade 316

The XWLSS50.15N from Annovi Reverberi is a Grade 316 stainless
steel industrial triplex plunger pump delivering 13.2 GPM at 2,200 PSI
at a controlled 1,450 RPM — engineered for food and
beverage processing, dairy and poultry sanitation, chemical rinse stations, marine
and port cleaning, fleet and fire department wash stations, and any continuous-duty
industrial cleaning environment where standard brass manifold pumps fail prematurely
from chemical attack, caustic cleaning agents, constant moisture exposure, or
salt-laden air. The XWLSS50.15N 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, heavy-duty chemical-compatible
seals, and oversized bearings into a 37-lb continuous-duty industrial pump backed
by a 5-year commercial warranty with U.S.-based service support.

The defining specification of the XWLSS50.15N is the
Grade 316 stainless steel manifold head — not 304 stainless,
not stainless-lined brass, but full Grade 316 construction specifically chosen for
its superior resistance to chloride attack, high-pH caustic cleaning solutions,
sanitizers, and the salt-laden environments that accelerate corrosion in marine
and coastal industrial facilities. Where standard brass manifold pumps in the same
13.2 GPM output class require early replacement due to chemical degradation in
food processing and sanitation environments, the XWLSS50.15N’s Grade 316
construction provides the service life that demanding chemical exposure
applications require.

Why Grade 316 Stainless Steel Changes the Application

XWLSS50.15N — When Brass Manifold Pumps Are Not the Right Answer

The choice between a brass manifold pump and the XWLSS50.15N
is not about preference — it is about the chemistry of the cleaning environment.
Brass manifolds perform reliably in standard water and mild detergent applications.
They degrade in environments with repeated caustic chemical exposure, high-pH
sanitizers, chloride-bearing cleaning agents, and constant moisture cycling that
never allows the manifold surface to dry between operating sessions.

Grade 316 stainless steel is the correct manifold material for
these conditions — it is the same alloy specification used in food processing
equipment, pharmaceutical manufacturing, marine hardware, and chemical processing
components specifically because of its resistance to chloride pitting, caustic
attack, and the accelerated surface degradation that standard stainless 304
and brass experience in these environments.

For dairy processing facilities running caustic rinses and acid wash cycles,
food production lines using approved sanitizers, poultry processing plants
with high-pH cleaning protocols, marine wash stations with constant salt
exposure, and chemical rinse stations where pump manifold longevity has been
a persistent maintenance problem, the XWLSS50.15N’s Grade 316 manifold
is the correct specification — not an upgrade, but the right tool for
the application.

XWLSS50.15N High-Flow Industrial Performance

13.2 GPM at 2,200 PSI for Large-Scale Sanitation and Washdown

The XWLSS50.15N uses a triplex plunger system where three
ceramic plungers operate in synchronized reciprocation — producing smooth,
consistent 13.2 GPM output at 2,200 PSI with substantially reduced pulsation
versus axial or wobble-plate designs at equivalent flow. The balanced
three-cylinder cycle protects downstream hose assemblies, spray bars, surface
cleaners, and multi-gun manifold systems from hydraulic fatigue across long
continuous industrial operating shifts.

At 1,450 RPM, the XWLSS50.15N’s ceramic plungers, stainless
valve seats, chemical-compatible seals, and oversized bearings all operate at
a controlled rate that maintains stable internal temperatures — critical for
food processing and dairy facilities running the pump across multiple daily
sanitation cycles where heat accumulation and chemical compatibility are both
active concerns. The oversized crankcase and bearings provide the thermal
stability needed to sustain 13.2 GPM continuous output across long industrial
operating schedules without the heat-induced seal degradation that affects
smaller bearing specifications at equivalent flow rates.

The 24 mm solid keyed shaft supports belt-drive, gear-drive,
and electric motor flange installations — making the XWLSS50.15N adaptable to
fixed industrial wash station configurations, trailer-mounted contractor systems,
and electric motor-driven sanitation platforms across the diverse installation
types encountered in food processing, marine, and
large-facility cleaning environments.

XWLSS50.15N Industrial-Grade Component Specification

Every Wet-End Component Chosen for Chemical Exposure Resistance

• Grade 316 stainless steel manifold head:
  the XWLSS50.15N’s defining specification — superior
  resistance to chloride attack, caustic cleaning agents,
  high-pH sanitizers, and marine salt exposure versus
  brass manifolds and Grade 304 stainless alternatives
  in the same output class
• Ceramic plungers for chemical washdown cycles:
  heat and abrasion resistance that limits thermal transfer
  into the packing stack — extending water-seal service life
  in the frequent start/stop sanitation cycles and chemical
  concentration variations of food processing
  and dairy environments
• Stainless steel valves throughout: consistent
  sealing and corrosion resistance in the chemical-bearing
  water streams of food processing, poultry, dairy, and
  marine cleaning applications where brass valve
  components would corrode prematurely
• Heavy-duty chemical-compatible seals:
  engineered specifically for sanitizer, caustic agent, and
  acid wash compatibility — the seal specification appropriate
  for food processing and chemical rinse environments
  rather than standard commercial
  washdown chemistry
• Oversized crankcase and bearings: thermal
  stability under sustained 13.2 GPM continuous industrial
  loads — critical in food processing and dairy facilities
  where the pump may run extended sanitation cycles
  with minimal idle time
• Oil sight glass and vented dipstick: complete
  daily crankcase monitoring in seconds before each operating
  shift — routine maintenance access appropriate for
  industrial facility maintenance schedules

XWLSS50.15N Key Benefits

Grade 316 Stainless Performance for the Applications Brass Cannot Handle

• Grade 316 stainless — not brass, not 304:
  the specific alloy specification required for chloride
  environments, caustic cleaning agents, and high-pH
  sanitizer exposure — the XWLSS50.15N is built for
  the applications where brass manifold pumps
  fail prematurely
• 13.2 GPM for maximum sanitation throughput:
  the high flow volume that covers large food processing
  floors, dairy parlors, vehicle wash bays, and parking
  structures efficiently in fewer passes — more area
  sanitized per shift than lower-flow
  alternatives at equivalent pressure
• 2,200 PSI surface-safe for food and dairy
  environments: effective mechanical cleaning action
  on processing equipment, stainless steel surfaces,
  concrete floors, and vehicle exteriors without
  surface damage risk on equipment
  and facility components
• 1,450 RPM continuous-duty low-speed design:
  thermal stability and reduced component fatigue across
  the extended daily sanitation cycles of food processing,
  dairy, and industrial cleaning operations
• 24 mm shaft for three-way drive flexibility:
  belt-drive, gear-drive, and electric motor flange
  compatible — the same installation flexibility as the
  XWP50.15N brass manifold counterpart for
  replacement and new-build applications
• Stainless valves and chemical-compatible seals
  throughout: the entire wet end is specified for
  chemical exposure environments — not just the manifold
  head but every component that contacts the
  cleaning solution stream
• 37-lb compact industrial package:
  manageable weight for a 13.2 GPM Grade 316 stainless
  industrial pump — practical for mobile contractor
  and trailer-mounted sanitation
  system installations
• 5-year commercial warranty on Grade 316
  construction: exceptional coverage for a premium
  stainless industrial pump platform — backed by U.S.-based
  nationwide service centers and the global
  Annovi Reverberi parts network

XWLSS50.15N Typical Applications

Where Grade 316 Stainless at 13.2 GPM and 2,200 PSI Is the Correct Specification

• Food and beverage processing facilities:
  floor and equipment washdown where repeated caustic
  rinse and sanitizer cycles demand the Grade 316
  stainless manifold specification that resists chemical
  degradation across the full operating season —
  OEM machine builders should follow facility
  certification requirements for their
  completed system configurations
• Dairy and poultry processing sanitation:
  parlors, processing rooms, and production equipment
  where high-pH cleaning protocols and chloride-bearing
  sanitizers make Grade 316 stainless the required
  manifold specification for long-term
  pump reliability
• Chemical rinse stations: industrial facilities
  running aggressive cleaning chemistries where the
  XWLSS50.15N’s complete stainless wet end — manifold,
  valves, and chemical-compatible seals — provides the
  corrosion resistance that brass manifold pumps
  cannot sustain
• Marine and port cleaning operations: vessel
  washdown, dock maintenance, and coastal industrial
  facilities where salt-laden air and seawater exposure
  accelerate brass manifold corrosion — Grade 316
  stainless construction handles marine
  environments reliably
• Fleet and fire department wash stations:
  high-volume vehicle washing where 13.2 GPM at 2,200 PSI
  supports rapid fleet turnover and the stainless
  construction handles the full range of vehicle
  cleaning detergents and foam
  applications
• Restaurant hood and duct cleaning contractors:
  high-temperature chemical degreasing environments where
  the XWLSS50.15N’s Grade 316 manifold and
  chemical-compatible seals handle degreaser chemistry
  that degrades standard
  brass manifold pumps
• Large building and parking garage maintenance:
  high-volume floor and surface cleaning at scale where
  13.2 GPM output with the XWLSS50.15N’s stainless
  construction handles diverse cleaning chemistries
  encountered in large-facility
  maintenance programs

XWLSS50.15N Installation & Maintenance

Best Practices for Grade 316 Stainless Industrial Pump Performance

• Select the correct drive interface: the
  XWLSS50.15N’s 24 mm solid keyed shaft accommodates
  belt-drive sheaves, gear-drive couplings, and electric
  motor flange adapters — confirm drive type and RPM
  reduction to deliver rated 1,450 RPM at the
  pump shaft under operating load
• Mount on a rigid, corrosion-resistant base:
  in marine, food processing, and chemical rinse
  environments, structural mounting hardware should match
  the XWLSS50.15N’s stainless construction —
  carbon steel mounting hardware corrodes
  in the same environments that
  demand stainless pumps
• Size inlet plumbing for 13.2 GPM: adequate
  supply line diameter and NPSH margin is critical at
  this flow rate — cavitation at 13.2 GPM damages
  ceramic plungers and valve seats and is
  not covered under warranty
• Use compatible inlet filtration: install
  a corrosion-resistant strainer appropriate for the
  chemical environment — standard carbon steel strainers
  corrode in the same chemical applications where the
  XWLSS50.15N’s stainless construction
  is required
• Flush between different chemical applications:
  always flush the XWLSS50.15N with clean water between
  caustic and acid wash cycles — mixed chemistry residue
  in the manifold and valve passages accelerates internal
  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 bearing longevity in 13.2 GPM continuous
  industrial operation
• Never run dry: always confirm water supply
  is flowing before starting — dry operation damages
  ceramic plunger packings immediately and voids
  the 5-year warranty
• First oil change at approximately 50 hours:
  then follow Annovi Reverberi’s duty-cycle maintenance
  schedule — intensive food processing and dairy sanitation
  cycles benefit from more frequent oil service than
  intermittent commercial use
• Winterize with food-safe antifreeze where
  required: in food processing environments, confirm
  antifreeze compatibility with facility food safety
  protocols — drain completely where food-safe
  antifreeze is not acceptable
