RKSS11.11N | Stainless Triplex Pump, 3 GPM 3000 PSI, 24mm Shaft

RKSS11.11N Stainless Triplex Pump | 2.9 GPM 3000 PSI AISI 316L Bronze Viton

RKSS11.11N — the Annovi Reverberi AISI 316L stainless steel
triplex plunger pump delivering 2.9 GPM at 3,000 PSI at a
controlled 1,450 RPM — engineered for USDA-compliant food and
dairy washdown, chemical wash stations, meat packing and beverage production
sanitation, marine and coastal facility cleaning, restaurant hood and duct
contractor rigs, and any continuous-duty industrial environment where chlorides,
caustic cleaners, disinfectants, and corrosive vapors demand AISI 316L stainless
construction over brass. The RKSS11.11N is built on a
24 mm solid keyed shaft compatible with belt-drive, gearbox,
and engine-coupled systems — combining an AISI 316L stainless pump head,
bronze connecting rods, ceramic plungers, stainless steel
valves, and Viton o-rings into a 22-lb continuous-duty
stainless pump backed by a 5-year commercial warranty with
U.S.-based service support.

The RKSS11.11N is the lowest-flow model in the RK-SS 1450 RPM
solid shaft lineup — at 2.9 GPM and 3,000 PSI it is tuned for single-gun
washdown systems, compact wash carts, and targeted cleaning stations in food
processing, chemical, and marine environments where steady controlled output
and chemical resistance matter more than maximum volume. Bronze connecting rods
and Viton o-rings confirm the RKSS11.11N’s specification for demanding chemical
exposure environments — bronze delivers superior fatigue strength and corrosion
resistance in the oil-bath crankcase at 1,450 RPM sustained industrial loads,
and Viton provides seal compatibility with the caustic cleaning agents,
disinfectants, and hot-water cycles of food processing and
sanitation applications.

Why AISI 316L, Bronze Rods, and Viton Define the RKSS11.11N

Three Specifications Chosen for the Chemistry of Industrial Sanitation

The RKSS11.11N’s three material specifications are not
independent upgrades — they work together to address the complete set of
corrosion, fatigue, and seal compatibility challenges in the industrial
chemical washdown environments this pump is built for.

AISI 316L stainless pump head addresses manifold corrosion —
chloride pitting, dezincification, and caustic attack that cause premature
failure in brass-head pumps in food processing, dairy, marine, and chemical
environments. AISI 316L’s molybdenum content provides the additional chloride
resistance that Grade 304 stainless lacks in high-chloride cleaning
environments.

Bronze connecting rods address drivetrain fatigue at sustained
chemical washdown duty cycles — at 1,450 RPM and 3,000 PSI, the connecting
rod experiences combined tensile, compressive, and bending loads continuously
across industrial operating shifts. Bronze’s fatigue strength and corrosion
resistance in the oil-bath crankcase environment outperforms aluminum rod
alternatives across the multi-year service life the RKSS11.11N is specified for
in food processing and sanitation program applications.

Viton o-rings address seal chemical compatibility — caustic
soda, chlorinated disinfectants, concentrated detergents, and hot-water cycles
exceed the compatibility range of standard EPDM and Buna-N seals. Viton’s
broad chemical resistance covers the cleaning agent concentrations and
temperatures encountered in USDA-compliant food processing, meat packing,
dairy, and chemical rinse applications.

RKSS11.11N Performance and Operating Envelope

Controlled 2.9 GPM at 3,000 PSI for Targeted Sanitation Applications

• 2.9 GPM for single-gun targeted cleaning:
  thorough rinsing of equipment surfaces, small tanks,
  process lines, and facility floor areas without
  overwhelming drains or generating overspray around
  instrumentation and sensitive
  processing surfaces
• 3,000 PSI for effective cutting on industrial
  soils: removes fats, proteins, oils, and residues
  from concrete pads, stainless equipment, and painted
  structures when used with compatible cleaning agents
  and appropriate nozzle selection
• Low-pulsation triplex output: balanced
  three-cylinder cycle improves operator control and
  reduces fatigue at the gun or lance across extended
  sanitation shifts in food processing
  and industrial facilities
• 1,450 RPM slow-speed advantage: lower
  mechanical stress, reduced internal temperature, and
  lower noise versus 3,400 RPM direct-drive alternatives
  at equivalent output — critical in food processing
  environments where noise and heat are
  operational concerns
• Tunable output for diverse sanitation tasks:
  with correct nozzle selection and unloader setting,
  the RKSS11.11N output can be tuned from light rinsing
  to aggressive degreasing within the 3,000 PSI
  maximum pressure rating

RKSS11.11N Drive and System Integration

24mm Solid Shaft for Belt-Drive, Gearbox, and Engine-Coupled Installations

• Belt-drive, gearbox, and flexible coupler
  compatibility: the RKSS11.11N’s 24 mm keyed
  shaft allows precise speed matching to available motors
  and engines across fixed central systems, OEM engineered
  skids, and contractor portable
  stainless rigs
• Stainless skid and washdown-zone mounting:
  mounting footprint supports installation on stainless
  skids, epoxy-coated bases, and mobile frames in
  washdown and outdoor corrosive
  environments
• Fixed central and multi-zone service
  configurations: the RKSS11.11N integrates into
  both fixed central washdown systems and portable rigs
  serving multiple work zones, dock positions, or
  production line areas
• Inlet sizing for 2.9 GPM without cavitation:
  size inlet plumbing, strainers, and valves to support
  2.9 GPM with minimal pressure drop — cavitation at
  this duty point damages ceramic plungers and Viton
  seals and voids warranty coverage
• All downstream components rated for 3,000 PSI:
  unloader, safety relief valve, hose assemblies, and spray
  guns must be rated at or above 3,000 PSI and chemically
  compatible with all cleaning agents
  in the system

RKSS11.11N Typical Applications

Where AISI 316L, Bronze, and Viton at 2.9 GPM and 3,000 PSI Are the Right Specification

• USDA-compliant food and dairy washdown:
  stainless construction and controlled 3,000 PSI output
  for sanitation-critical areas — OEM machine builders
  should follow facility certification requirements
  for completed system configurations
• Chemical wash stations and sanitation rigs:
  processing plants and laboratories handling caustic
  cleaners and disinfectants where the RKSS11.11N’s
  AISI 316L manifold and Viton seals handle the
  chemistry that degrades
  brass manifold pumps
• Meat packing, dairy, and beverage production:
  high-pH cleaning protocols and frequent hot-water
  washdowns in protein processing environments where
  bronze rods, Viton seals, and AISI 316L construction
  provide the service life that
  standard pumps cannot
• Marine and coastal cleaning: docks, vessels,
  equipment, and structures exposed to salt spray and
  corrosive atmospheres where AISI 316L’s chloride
  resistance is the required
  manifold specification
• Restaurant hood and duct cleaning contractors:
  high-temperature degreaser chemistry in contractor
  cleaning rigs where the RKSS11.11N’s Viton seals
  and stainless construction handle degreaser exposure
  across seasonal
  operating schedules
• Environmental services and chemical remediation:
  corrosion-resistant pumping hardware for chemical
  rinse systems and remediation equipment where
  AISI 316L stainless provides the manifold durability
  that environmental chemistry demands

RKSS11.11N Maintenance and Rebuild Planning

Preventive Service for Long-Term AISI 316L Stainless Platform Performance

• Daily pre-shift inspections: verify oil
  level and clarity via sight glass, check for leaks at
  all connections, confirm drive alignment, and monitor
  operating pressure under load before each
  production shift
• Planned seal and valve replacement intervals:
  schedule rebuild around run hours, temperature exposure,
  and chemical loading — planned maintenance minimizes
  unplanned downtime in critical food processing
  and sanitation areas
• Rebuild rather than replace: seal and valve
  kits available for the RKSS11.11N — the hydraulic
  section is rebuildable at planned intervals, extending
  the useful life of the AISI 316L pump head and
  bronze crankcase assembly investment
• Never run dry: always confirm water supply
  is flowing before starting — dry operation at 3,000 PSI
  damages ceramic plunger packings and Viton seals
  immediately and voids
  warranty coverage
• Flush between chemical applications: run
  clean water through the RKSS11.11N between caustic and
  acid wash cycles — mixed chemistry residue in manifold
  passages accelerates degradation
  even on AISI 316L construction
• First oil change at approximately 50 hours:
  then follow Annovi Reverberi’s duty-cycle preventive
  maintenance schedule with intervals appropriate to
  chemical exposure intensity in the
  installed environment
• Winterize with compatible antifreeze: in
  food processing and dairy environments confirm
  antifreeze compatibility with facility food safety
  protocols — drain completely where chemical
  antifreeze is not acceptable
