RKASS3G15N | 3 GPM 3000 PSI Triplex Pump, 1750 RPM, SS 24mm

RKASS3G15N — 3.0 GPM 1500 PSI Stainless Triplex Pump, 1450 RPM, 24 mm Shaft

• The RKASS3G15N is a compact stainless-head triplex plunger pump engineered for commercial and industrial systems that need long service life in a small footprint.
• Delivering 3.0 GPM at 1500 PSI while running at 1450 RPM, it provides steady cleaning power with low vibration and reduced noise, making it suitable for indoor and enclosed installations.
• A 24 mm solid keyed shaft supports both direct-drive and belt-drive layouts, giving designers flexibility to pair the pump with gas engines, electric motors, or gear-reduction packages.
• Stainless steel head construction, forged brass manifold, ceramic plungers, and stainless valves combine to deliver reliable operation in washdown and sanitation environments that demand corrosion resistance.

Performance and Operating Profile

• Rated 3.0 GPM at 1500 PSI, the RKASS3G15N is targeted at light-to-medium industrial cleaning tasks where controlled flow and moderate pressure are preferred over extreme output.
• The 1450 RPM operating speed reduces friction and heat inside the crankcase, supporting longer seal, valve, and bearing life under continuous-duty conditions.
• Triplex plunger geometry produces low-pulsation output, improving gun stability and accessory performance while reducing fatigue for operators working around the system.
• The flow and pressure envelope is suitable for single-gun and small manifold systems in facilities that run daily cleaning, sanitation, or maintenance routines.

Flow, Pressure, and Duty Range for RKASS3G15N

• 3.0 GPM provides efficient rinsing capability for equipment, vehicles, and work areas without demanding excessive water supply or drainage capacity.
• 1500 PSI offers effective cleaning impact for soils, residues, and light greases on common industrial and commercial surfaces while helping protect more delicate finishes.
• When combined with correctly sized nozzles and unloaders, the pump maintains stable working pressure for wands, foamers, and small surface cleaners.
• The design supports continuous commercial duty when inlet conditions, bypass arrangements, and chemical use are managed within recommended specifications.

Pump Construction and Wet-End Components of RKASS3G15N

• The stainless steel head provides enhanced resistance to corrosion in environments exposed to detergents, sanitizers, and frequent washdown cycles.
• A forged brass manifold reinforces structural strength around the wet end, helping maintain sealing tolerances under pressure and temperature changes.
• Solid ceramic plungers offer a hard, dimensionally stable surface for the packing sets, reducing wear and limiting heat transfer into the seal area.
• Stainless steel valves are specified for consistent seating and long-term volumetric efficiency in damp, chemical-rich environments.

Seals, Valves, and Serviceability

• High-pressure seal packs are configured for 1500 PSI operation with clean water and compatible cleaning agents used within manufacturer temperature guidelines.
• Valve assemblies can be replaced using standard service kits, allowing technicians to restore capacity and pressure after extended run hours.
• The head and manifold are designed for straightforward access, so seal and valve changes can be performed with common shop tools during planned maintenance.
• Proper filtration, inlet line sizing, and chemical management further extend seal and valve life and help maintain predictable service intervals.

Drive Integration and System Layout

• The 24 mm solid keyed shaft integrates with belt-drive arrangements for gas or electric power, allowing designers to select pulley ratios that hold pump speed near 1450 RPM.
• In direct-drive configurations, the shaft supports coupling to gearboxes or close-coupled motor packages when compact systems are required.
• The pump’s footprint and mounting pattern allow installation on skids, carts, wall-mounted brackets, or cabinet systems with straightforward guarding.
• The RKASS3G15N can be combined with unloaders, regulators, and safety valves chosen for 3.0 GPM at 1500 PSI to create reliable, balanced wash packages.

System Compatibility

• Compatible with standard pressure washer accessories such as hose reels, lances, spray guns, foamers, and small rotary tools matched to the pump’s output.
• Works with chemical injection systems configured for downstream or upstream use, provided materials and pressures are within the pump’s rated limits.
• Bypass plumbing can be configured to return to tank or inlet manifolds as required by plant standards and thermal management practices.
• The compact size and stainless wet end make the pump a strong candidate for OEMs developing small, purpose-built washdown or sanitation modules.

Maintenance, Inspection, and Reliability

• The crankcase is supplied with pre-installed break-in oil, simplifying initial commissioning and protecting internal components during the first hours of operation.
• An oil sight glass is integrated into the crankcase, enabling quick verification of oil level and basic condition during daily or pre-shift inspections.
• The vented dipstick helps regulate crankcase pressure and provides clean access for draining and refilling oil at scheduled service intervals.
• When run within specified inlet pressure, temperature, and lubrication guidelines, the RKASS3G15N is designed for long, predictable service life in demanding commercial environments.

Preventive Maintenance Practices

• Recommended routines include checking oil level and clarity, inspecting fittings and head surfaces for leaks, and confirming stable operating pressure under typical load.
• Seal and valve replacement intervals can be based on run hours, water quality, chemistry, and temperature to align with facility maintenance programs.
• Regular inspection of inlet strainers, suction hoses, and unloader operation helps prevent cavitation and pressure spikes that shorten component life.
• Following documented rebuild procedures allows the pump to remain in service through multiple overhaul cycles, supporting long-term asset planning and consistent performance.

Applications and Use Cases for RKASS3G15N

• Food service and USDA-style sanitation washdowns when paired with appropriate stainless piping, nozzles, and sanitation procedures.
• Mobile contractor and detailing rigs that require a compact, low-RPM pump with stainless wet-end components.
• HVAC coil cleaning and mechanical room maintenance where controlled flow and moderate pressure are preferred in confined spaces.
• Agricultural, dairy, and small fleet maintenance systems that demand regular washdown with reliable 3.0 GPM performance.
• OEM skid, cart, and cabinet systems where a stainless-head triplex pump is required but space and power budgets favor a smaller frame size.
• General industrial washdown for equipment, work areas, and support systems in facilities that run daily cleaning operations.
