RKASS35G25E-F17 | 3.5 GPM 2500 PSI Triplex Pump, 1750 RPM, SS 182/184C

RKASS35G25E-F17 — 3.5 GPM 2500 PSI Stainless Steel Triplex Pump, 1750 RPM, F17 Motor Flange

• The RKASS35G25E-F17 is a stainless steel industrial triplex plunger pump engineered for direct mounting to NEMA 182–184C electric motors in demanding washdown and sanitation environments.
• Rated 3.5 GPM at 2500 PSI and 1750 RPM, it provides a strong, controllable wash stream suitable for production floors, equipment bays, and centralized plant wash systems.
• The stainless head, ceramic plungers, and stainless valves are specified for long service life where detergents, sanitizers, and moisture are present every shift.
• A 24 mm solid shaft combined with the E-series F17 motor flange delivers a rigid, compact pump-and-motor assembly that reduces alignment challenges and simplifies installation on industrial frames and skids.

Performance and Operating Profile

• With 3.5 GPM at 2500 PSI, the RKASS35G25E-F17 offers a practical balance of impact and coverage, well suited for cleaning equipment, walls, floors, vehicles, and work areas with consistent results.
• Operating at 1750 RPM, the pump matches standard 4-pole motor speeds, providing predictable behavior and manageable noise levels in mechanical rooms, utility corridors, and process areas.
• Triplex plunger design delivers low-pulsation output, improving spray stability at the gun and reducing fatigue on hoses, fittings, and nozzles under continuous-duty operation.
• When paired with properly sized unloaders, nozzles, and plumbing, the pump maintains steady working pressure throughout long washes and multi-shift sanitation schedules.

Flow, Pressure, and Duty Range of RKASS35G25E-F17

• 3.5 GPM provides enough volume to flush away soils, chemicals, and rinse water quickly without overwhelming drainage systems or reclaim equipment when configured correctly.
• 2500 PSI gives strong cleaning impact for baked-on residues, oily films, and tracked dirt while remaining controllable on coated or painted surfaces with appropriate nozzle selection.
• The performance window fits single-gun stations, compact manifolds, and localized wash zones where repeatable cleaning is required multiple times per day.
• Duty range is intended for frequent or continuous use when inlet conditions, chemistry, and temperatures remain within manufacturer guidelines for long-term reliability.

F17 Motor Flange Integration fits RKASS35G25E-F17

• E-series F17 flange is designed for direct mounting to NEMA 182–184C motors with a 1-1/8″ keyed shaft, creating a factory-style interface between the electric motor and pump.
• Direct coupling reduces alignment time, eliminates separate base-plate coupling hardware, and lowers the risk of misalignment-induced bearing and seal wear over time.
• The compact motor-mounted configuration works well on wall brackets, floor stands, carts, and skids where footprint and access are tightly controlled.
• With the pump supported at the motor face, vibration characteristics are consistent and can be managed using standard mounting hardware and isolation pads.

System Layout and Controls

• The 1750 RPM direct-drive arrangement is compatible with across-the-line starters, soft starters, or VFDs, allowing facilities to manage inrush current and acceleration profiles as required.
• Electrical protection should be coordinated with pump pressure settings, unloader adjustment, and nozzle sizing so the motor operates within its horsepower envelope.
• Compact geometry simplifies routing of suction lines, discharge manifolds, hose reels, and chemical injection points around a central pump-and-motor module.
• When integrated with correctly sized unloaders, relief valves, and bypass plumbing to tank or drain, the system can operate safely in continuous or frequent-start applications.

Construction and Wet-End Design

• Stainless steel head RKASS35G25E-F17 provides robust corrosion resistance in washdown environments where alkaline cleaners, sanitizers, and frequent rinsing are standard practice.
• Stainless valves maintain tight sealing and accurate flow control under repeated cycling, pressure changes, and temperature swings typical of industrial sanitation work.
• Solid ceramic plungers offer a hard, dimensionally stable surface for the packing sets, reducing wear and limiting heat transfer into the seal area during extended operation.
• Oversized bearings and a robust crankshaft design support the mechanical loads associated with continuous duty at 1750 RPM, helping to maintain alignment of the rotating group.

Seals, Bearings, and Serviceability

• High-pressure packing assemblies are specified for 2500 PSI service with clean water and compatible cleaning agents used within recommended temperature and concentration ranges.
• RKASS35G25E-F17 Seal and valve kits are available so maintenance teams can perform planned wet-end rebuilds, restoring performance without replacing the complete pump.
• Head and valve layout is designed for straightforward access with common shop tools, allowing rebuild work to be completed during scheduled shutdowns or off-shift maintenance windows.
• Appropriate inlet filtration, suction hose sizing, and controlled chemical introduction help extend seal and valve life while minimizing cavitation risk.

Maintenance, Inspection, and Reliability

• The crankcase is shipped with break-in oil pre-installed, simplifying commissioning and protecting internal components during initial run-in.
• An integrated oil sight glass provides quick visual confirmation of oil level and basic condition as part of daily inspection routines.
• The vented dipstick regulates crankcase pressure and serves as the access point for draining and refilling oil at scheduled service intervals.
• When operated within specified limits for inlet conditions, temperature, lubrication, and speed, the RKASS35G25E-F17 is designed to deliver long, predictable service life in continuous-duty washdown applications.

Preventive Maintenance Practices of RKASS35G25E-F17

• Recommended checks include monitoring oil level and clarity, inspecting fittings and the head for seepage, and verifying stable system pressure under normal operating load.
• Seal and valve replacement intervals can be established based on run hours, water quality, chemical exposure, and operating temperature, aligning rebuilds with broader facility maintenance plans.
• Routine cleaning of inlet strainers and inspection of suction lines helps prevent flow restriction and cavitation that can shorten pump life.
• Documented service history and adherence to manufacturer procedures support multiple rebuild cycles, improving lifecycle cost and overall system reliability.

Applications and Use Cases for RKASS35G25E-F17

• Manufacturing plant and equipment cleaning, including production machinery, conveyors, guarding, and structural members exposed to process residues and dust.
• Vehicle and truck wash bays for municipal fleets, distribution centers, rental operations, and maintenance shops using indoor electric pressure systems.
• Restaurant hood and duct cleaning systems that require stainless wet ends and controlled pressure for use with hot water and degreasing solutions.
• Public works and municipal washdown operations, including service garages, transit facilities, and utility yards where reliable daily cleaning is required.
• Food processing and packaging facilities where stainless construction and electric drive support sanitation, ventilation, and safety requirements.
• OEM and contractor-built electric skids or centralized wash stations that need a 3.5 GPM, 2500 PSI stainless triplex pump with F17 motor-flange integration.
