WJTA

The official WJTA mobile app puts essential field tools and member resources in your pocket—built for technicians, supervisors, and authorized personnel in high-pressure waterjetting, hydroblasting, and industrial vacuum operations.

Whether you are sizing equipment on the jobsite, checking safety references, or staying current with industry updates, WJTA gives your team fast, reliable access to the resources you use every day.

FIELD CALCULATOR SUITE (OFFLINE CAPABLE) Run practical hydroblasting and vacuum calculations anywhere—even without a connection: • Pump Flow Calculator — solve for pressure, flow rate, or horsepower (HHP/IHP) • Nozzle / Orifice Sizing — size nozzles with pressure-loss analysis for hose, lances, and couplings • Tank Volume Calculator — estimate material capacity and payload weight for vacuum trucks and combo units • Material Weight Calculator — calculate load weight from tank volume, fill level, and material density

Imperial and metric units are supported across calculators.
