RTX70-DD-SX 18.5 GPM 2900 PSI Pump | Left-Hand Direct Drive Hydraulic

AR RTX70-DD-SX Left-Hand Hydraulic Direct-Drive Triplex Pump

The AR RTX70-DD-SX is a left-hand rotation, hydraulic direct-drive triplex plunger pump engineered for
continuous-duty environments demanding high flow, stable pressure, and long operational life. Delivering
18.5 GPM at 2,900 PSI, this model is purpose-built for industrial wash bays, agricultural sanitation
systems, fleet maintenance operations, and mobile hydraulic cleaning platforms that require dependable,
high-volume water output. The left-hand configuration supports mirrored system layouts, dual-pump
assemblies, and specialized hydraulic installations where directional rotation is a critical requirement.

Designed for direct coupling to hydraulic motors, the RTX70-DD-SX eliminates belts, pulleys, and gear
reduction systems—reducing vibration, decreasing noise, and minimizing service points. This configuration
ensures maximum torque transfer from the hydraulic motor to the crankshaft, enhancing energy efficiency and
lowering long-term operating costs. Built within AR’s heavy-duty RTX architecture, this pump provides
industrial reliability for applications where downtime is not an option.
