RKSS13.17N | 3.5 GPM 3000 PSI Triplex Pump, 1450 RPM, SS 24mm

Annovi Reverberi RKSS13.17N Stainless Triplex Pump | 3.5 GPM 2500 PSI AISI 316 Grade

RKSS13.17N — the Annovi Reverberi AISI 316 stainless steel
triplex plunger pump delivering 3.5 GPM at 2,500 PSI at
1,450 RPM — engineered for pharmaceutical and hygienic facility
sanitation, food and beverage processing washdown, chemical cleaning stations,
industrial plant maintenance, and any continuous-duty environment where chlorides,
caustic soda, disinfectants, and aggressive cleaning vapors demand stainless
manifold construction over brass. The RKSS13.17N is built on a
24 mm solid shaft compatible with belt-drive, gearbox-coupled,
and direct-coupled electric motor systems — combining an AISI 316 stainless steel
manifold head, ceramic plungers, stainless valve assemblies, and chemical-compatible
sealing elements into a medium-duty stainless pump backed by a
5-year commercial warranty with U.S.-based service support.

The RKSS13.17N is tuned for the medium-duty chemical washdown
duty point where steady, controlled output matters more than maximum flow —
3.5 GPM provides thorough equipment rinsing, process line flushing, and floor
cleaning coverage without overwhelming drains or generating excessive overspray
around instrumentation and sensitive surfaces, while 2,500 PSI delivers strong
cutting action on grease, food residue, and chemical contamination. The 1,450 RPM
slow-speed design keeps internal temperatures stable and extends bearing and seal
service life across the extended sanitation shifts that pharmaceutical, food
processing, and chemical processing facilities require from their
daily cleaning platforms.

AISI 316 Stainless Construction — The RKSS13.17N Specification Choice

When Brass Head Pumps Fail Prematurely in Chemical Washdown Environments

The RKSS13.17N is specified for environments where brass manifold
pumps experience dezincification, pitting, and rapid head corrosion from repeated
exposure to the cleaning chemistry the application requires. AISI 316 stainless
steel provides resistance to chloride attack, caustic soda degradation,
disinfectant concentration exposure, and the aggressive vapors present in
pharmaceutical and chemical processing areas where conventional brass-head designs
require premature replacement.

Stainless wetted surfaces maintain structural integrity and sealing geometry even
after repeated exposure to hot water, steam, and harsh cleaning agents — the
dimensional stability that keeps valve seats seating correctly and manifold passages
holding their shape across the thermal cycling of frequent washdown operations.
Stainless hardware and fasteners on key external interfaces further improve
long-term serviceability in areas subject to constant washdown spray where
carbon steel fasteners rust and seize.

The RKSS13.17N’s ceramic plungers provide the hard, dimensionally
stable surface that packing sets require for long service life under continuous
stroking at 2,500 PSI — ceramic’s resistance to abrasion and heat transfer into
the seal stack is particularly valuable in the high-pH caustic cleaning cycles
of food processing and pharmaceutical sanitation programs. Stainless valve
assemblies deliver clean seating and reliable performance through the chemical
and thermal cycling that degrades standard valve materials in aggressive
washdown service.

RKSS13.17N Performance and Operating Envelope

Medium-Duty Stainless Output for Controlled Sanitation Applications

• 3.5 GPM for thorough controlled rinsing:
  enough volume for equipment surfaces, small tanks,
  process lines, and facility floor areas without
  overwhelming drains or generating excessive overspray
  around instrumentation and
  sensitive processing surfaces
• 2,500 PSI for strong cutting action without
  surface risk: effective mechanical cleaning on
  grease, food residue, chemical contamination, and
  road film while remaining manageable around delicate
  equipment and process instrumentation
  in washdown zones
• Compatible with foamers, sanitizing lances, and
  fan nozzles: the RKSS13.17N’s output profile
  works with the full range of nozzle and accessory types
  used in hygiene-focused maintenance and
  sanitation programs
• Single-gun washdown system sizing: the
  3.5 GPM duty point is optimized for single-operator
  food plant, chemical facility, and industrial wash bay
  systems that run daily without requiring
  high-excavation pressure output
• 1,450 RPM pairs with 4-pole electric motors:
  natural speed match for 4-pole motor configurations
  reduces or eliminates additional speed reduction
  hardware in many stainless electric
  washdown system designs

RKSS13.17N Drive and System Integration

24mm Shaft Flexibility for Stainless Washdown Platform Configurations

• Belt-drive, gearbox, and direct-coupled
  compatibility: the RKSS13.17N’s 24 mm solid shaft
  allows precise speed matching to available motors
  and drives across fixed central systems, compact service
  carts, and stainless skid
  installations
• Stainless skid and washdown-rated zone mounting:
  mounting footprint and shaft height support installation
  on stainless skids, epoxy-coated baseplates, and
  overhead racks in facility washdown zones where
  the environment demands corrosion-resistant
  construction throughout
• Fixed central and multi-zone service systems:
  the RKSS13.17N can be built into fixed central wash
  systems or compact carts that service multiple
  production lines and facility zones from
  a single pump installation
• Inlet sizing for 3.5 GPM without cavitation:
  supply from a properly vented feed tank with free-flowing
  suction plumbing — inlet lines, strainers, and valves
  must support 3.5 GPM with minimal pressure drop
  to protect seals and valve seats from
  cavitation damage
• All downstream components rated for 2,500 PSI:
  unloader, safety relief valve, hose assemblies, and
  spray guns must be rated at or above 2,500 PSI and
  chemically compatible with all cleaning agents
  used in the RKSS13.17N system

RKSS13.17N Typical Applications

Where AISI 316 Stainless at 3.5 GPM and 2,500 PSI Is the Required Specification

• Pharmaceutical and hygienic facility sanitation:
  controlled pressure, AISI 316 stainless construction,
  and cleanable surfaces for process integrity in
  pharmaceutical manufacturing and hygienic
  processing environments — follow facility
  validation and certification requirements for
  completed system configurations
• Food and beverage processing: frequent
  hot-water washdowns, foam application, and rinse cycles
  in USDA- or HACCP-driven operations where the
  RKSS13.17N’s stainless construction handles the
  chemistry that causes premature brass
  manifold failure
• Chemical washdown stations: processing plants,
  blending areas, and packaging lines where harsh
  detergents and caustic cleaners make AISI 316
  stainless the required manifold specification
  for reliable long-term
  pump performance
• Industrial plant maintenance: pipe and rack
  flushing, equipment cleaning, and general plant
  washdown in corrosive atmospheres where brass pump
  service life is unacceptably short for
  the maintenance program
• Fleet and vehicle washing in corrosive environments:
  coastal, chemical-rich, and marine-adjacent fleet
  washing locations where corrosion resistance is
  essential for long equipment life across
  seasonal operating schedules
• Public and commercial facilities: theme parks,
  stadiums, and high-moisture public areas requiring
  daily cleaning with detergents and disinfectants
  where the RKSS13.17N’s stainless construction
  handles constant chemical and
  moisture exposure

RKSS13.17N Maintenance and Rebuild Planning

Preventive Service for Long-Term Stainless Platform Performance

• Daily routine inspections: verify RKSS13.17N
  oil level and clarity via sight glass, check for
  leaks at all connections, confirm drive alignment,
  and verify stable operating pressure under load
  before each production shift
• Planned seal and valve replacement intervals:
  schedule replacement around run hours, chemical
  exposure, and duty cycle intensity — planned
  maintenance intervals minimize unplanned downtime
  in critical wash areas and food
  processing environments
• Rebuild rather than replace: seal and valve
  kits are available for the RKSS13.17N — the hydraulic
  section is rebuildable at wear intervals, extending
  the useful life of the stainless pump body
  and crankcase investment
• Never run dry: always confirm water supply
  is flowing before starting — dry operation at
  2,500 PSI damages ceramic plunger packings
  and voids warranty coverage
• Flush between chemical applications: run
  clean water through the RKSS13.17N between caustic
  and acid wash cycles — mixed chemistry residue
  in manifold passages accelerates degradation
  even on AISI 316 stainless construction
• First oil change at approximately 50 hours:
  then follow Annovi Reverberi’s preventive maintenance
  schedule with intervals appropriate to duty cycle
  intensity and chemical exposure in the
  installed environment
• Winterize with compatible antifreeze: in
  food processing and pharmaceutical environments
  confirm antifreeze compatibility with facility
  protocols — drain completely where chemical
  antifreeze is not acceptable
