RTX85-SX Industrial Triplex Plunger Pump – Left-Hand Shaft
System Role
- Industrial-grade triplex plunger pump engineered to deliver 22.5 GPM at 3,000 PSI for continuous-duty wash systems where high water volume and pressure stability are required.
- Left-hand (SX) shaft configuration supports reverse-rotation requirements, mirrored installations, and counter-rotating drivetrains where a standard right-hand pump cannot be used.
- Designed for high-hour industrial operation with a slow-speed 1,450 RPM duty cycle that minimizes heat buildup, vibration, and mechanical fatigue.
- 30 mm solid keyed left-hand shaft allows integration into heavy-duty belt-drive, gearbox, or direct-coupled power systems used in industrial machinery and wash equipment.

What’s Included RTX85-SX
Factory Provisioning
- Factory-installed break-in oil to allow immediate commissioning without pre-service preparation.
- Integrated oil sight glass for rapid visual oil-level checks during daily inspections.
- Vented dipstick to manage crankcase pressure and simplify routine oil servicing.
- Owner’s manual with maintenance schedules, torque values, and operating guidelines.
- Detailed service schematic to streamline parts identification and rebuild planning.
- Factory performance test verifying pressure output, flow accuracy, and seal integrity.
- Five-year commercial-use warranty backed by domestic parts availability and service centers.
Operation
Triplex Plunger Output
- Triplex plunger architecture uses three ceramic plungers driven by a precision-balanced crankshaft to deliver smooth, pulse-reduced flow.
- Reduced pulsation protects downstream components such as unloaders, hoses, valves, and spray accessories from pressure spikes.
- The left-hand shaft orientation allows the pump to rotate counter to standard right-hand units, enabling mirrored or opposing installations.
- 30 mm keyed shaft supports high torque loads common in industrial belt-drive and gearbox-driven systems.
- Low-speed 1,450 RPM operation lowers internal temperatures, helping seals and bearings survive extended runtime cycles.
- Oversized bearing architecture stabilizes the crankshaft under sustained high-flow and continuous-duty conditions.
Construction & Durability
Industrial Materials Package
- Forged brass manifold provides corrosion resistance, structural rigidity, and stable sealing surfaces under high pressure.
- Solid ceramic plungers resist abrasion, heat transfer, and scoring for long seal life.
- Stainless steel valve assemblies withstand chemical exposure, temperature fluctuation, and high cycle counts.
- Bronze connecting rods handle continuous mechanical loading while accommodating thermal expansion.
- Heavy-duty aluminum crankcase dissipates heat efficiently and maintains alignment during long shifts.
- Oil-bath lubrication continuously protects internal components and reduces friction-related wear.
