RKASS3.6G12N | Stainless Triplex Pump, 3.6 GPM 3000 PSI, 24mm Shaft

RKASS3.6G12N — 3.6 GPM 1200 PSI Stainless Steel Triplex Pump, 1750 RPM, 24 mm Shaft

• The RKASS3.6G12N is a stainless steel industrial triplex plunger pump designed for light-to-moderate duty cleaning in plants, service bays, and commercial facilities that require dependable daily performance.
• Rated 3.6 GPM at 1200 PSI at 1750 RPM, it provides controlled cleaning power that is well suited to washdown, rinse, and sanitation work without overwhelming surfaces, drains, or operators.
• The 24 mm solid keyed shaft supports flexible drive options, including belt-drive from gas engines, direct coupling to electric motors, or integration into OEM skid and cart systems.
• Stainless head, ceramic plungers, stainless valves, and an oil bath crankcase combine to deliver a robust, low-maintenance pump for commercial and industrial environments where chemicals and moisture are part of daily operation.

Performance and Operating Profile

• The RKASS3.6G12N delivers 3.6 GPM at 1200 PSI, providing a balanced combination of flow and pressure for cleaning equipment, floors, walls, and vehicles in controlled, repeatable cycles.
• Operating at 1750 RPM aligns the pump with standard 4-pole electric motor speeds and common belt ratios, simplifying drive selection and ensuring predictable hydraulic output.
• Triplex plunger design produces low-pulsation flow, yielding stable spray patterns that protect hoses, guns, and accessories from shock loading in continuous or frequent-duty applications.
• With appropriate nozzle selection and unloader settings, the pump maintains consistent operating pressure over extended run times, reducing the need for constant adjustment by the operator.

Flow, Pressure, and Duty Range of RKASS3.6G12N

• 3.6 GPM provides enough volume to rinse down machinery, product-contact surfaces, and work areas without excessive water usage, making it suitable for facilities that monitor consumption closely.
• 1200 PSI offers effective cleaning impact for general soils, light grease, and tracked-in dirt while remaining manageable for coatings, labels, and painted surfaces when paired with correct tips.
• The duty range is focused on single-gun or small-station systems where washdown tasks are performed multiple times per shift in production, maintenance, or janitorial roles.
• When operated within recommended inlet conditions, temperature limits, and chemical compatibility guidelines, the pump supports frequent or extended operation typical of commercial wash systems.

Construction and Wet-End Design of RKASS3.6G12N

• The stainless steel head is specified for environments where detergents, sanitizers, and frequent rinsing would challenge standard brass components, giving added resistance to corrosion and surface attack.
• Stainless steel valves provide reliable seating and flow control under repeated cycling, pressure changes, and moderate temperature swings found in wash bays and processing areas.
• Solid ceramic plungers offer a hard, dimensionally stable surface for the packing sets, controlling wear and limiting heat transfer into the seal zone during sustained operation.
• The crankcase is built around an oil bath design, supporting the crankshaft and connecting rods with a stable lubrication film for consistent operation at 1750 RPM.

Seals, Bearings, and Serviceability

• High-pressure packing assemblies are selected for 1200 PSI service when used with clean water and compatible cleaning agents kept within recommended temperature and concentration limits.
• Bearings are sized to handle the radial and axial loads of triplex operation at 1750 RPM, reducing vibration and helping maintain alignment of the rotating group over long service intervals.
• Valve and seal kits are available, allowing maintenance teams to rebuild the wet end on a planned schedule instead of replacing the complete pump assembly.
• The RKASS3.6G12N head and manifold layout provides straightforward access to valves and packings using common shop tools, supporting quick service during scheduled downtime or off-shift maintenance windows.

Integration and Drive Options for RKASS3.6G12N

• The 24 mm solid keyed shaft can be belt-driven from gas engines or electric motors, allowing designers to select pulley ratios that match desired flow and pressure to available horsepower.
• Direct coupling to an appropriate electric motor is also possible when alignment, guard design, and base mounting are handled according to standard rotating-equipment practices.
• The compact form factor fits easily on wall-mounted brackets, small skids, portable carts, and trailer frames where space and weight are constrained.
• Standard porting and mounting features enable straightforward integration into existing manifolds, hose reels, unloader assemblies, and valve banks used in established cleaning systems.

System Layout and Controls

• Proper system design includes a correctly sized unloader, pressure gauge, and safety relief valve to maintain stable working pressure and protect components from overpressure events.
• Inlet plumbing should provide generous flow with minimal restriction, including strainers and filters chosen to protect the pump from debris while maintaining adequate net positive suction conditions.
• Chemical injection points should be located and sized to avoid starving the pump or introducing incompatible fluids at concentrations beyond recommended limits.
• Hoses, lances, and nozzles must be selected for the 3.6 GPM, 1200 PSI duty point so that flow, pressure, and operator handling remain within intended ranges.

Maintenance, Inspection, and Reliability for RKASS3.6G12N

• The oil bath crankcase is equipped with a sight glass that allows quick confirmation of oil level and basic condition as part of daily inspection routines.
• A vented dipstick supports crankcase pressure control and provides an access point for draining and refilling oil at scheduled service intervals.
• The pump is shipped with factory-installed break-in oil, simplifying initial start-up and protecting internal components during the early hours of operation.
• When operated within the specified limits for speed, inlet conditions, lubrication, and temperature, the RKASS3.6G12N is designed to deliver long, predictable service life in commercial-duty applications.

Preventive Maintenance Practices

• Recommended daily checks RKASS3.6G12N include inspecting for leaks, verifying oil level and clarity, and confirming that the system reaches and holds the expected operating pressure.
• Planned seal and valve replacements can be scheduled based on run hours, water quality, chemical exposure, and temperature history, aligning pump maintenance with facility shutdowns or service windows.
• Regular cleaning of inlet strainers and inspection of suction hoses help prevent cavitation and starvation, which can shorten seal, valve, and bearing life.
• Maintaining basic service records and following manufacturer procedures support multiple rebuild cycles and predictable lifecycle cost for the pump and associated washdown equipment.

Applications and Use Cases of RKASS3.6G12N

• Agricultural sprayers and equipment rinsing where stainless construction helps withstand fertilizers, detergents, and outdoor exposure.
• Janitorial and facility cleaning in schools, shopping centers, and public buildings that require dependable washdown of walkways, loading areas, and service corridors.
• Fleet and vehicle cleaning for light-duty wash bays handling cars, vans, small trucks, and service vehicles.
• Food and beverage plant washdown where moderate pressure, stainless wet ends, and controlled flow support sanitation practices.
• Mobile contractor rigs and service carts that need a compact stainless triplex pump matched to 3.6 GPM, 1200 PSI operation at 1750 RPM.
• OEM-built cleaning modules and skid systems designed for medium-duty industrial cleaning with flexible engine or motor drive options.
