RTJ70 Industrial Pressure Washer Pump – 18.5 GPM @ 4000 PSI, 1000 RPM

Part Number: RTJ70
Category: Pressure Washer Pumps
Type: Industrial Triplex Pump – RTJ70, 18.5 GPM @ 4000 PSI (1000 RPM)

The RTJ70 Industrial Pressure Washer Pump is a heavy-duty, high-output triplex pump engineered for industrial systems that require both extreme pressure and massive flow. Delivering an impressive 18.5 GPM at up to 4000 PSI, this pump is built for large-scale cleaning, surface preparation, and industrial wash-down operations where power, reliability, and continuous-duty performance are non-negotiable.

Designed for 1000 RPM operation, the RTJ70 balances high output with reduced mechanical stress, extending service life under sustained workloads. With oversized internal components, a large oil capacity, and rugged triplex construction, this pump is purpose-built for nonstop industrial environments such as mining, shipyards, refineries, and heavy equipment maintenance facilities.
