Engine Drive for Mobile Mounting - incorporates a selected group of high-pressure, engine driven units with special design features and operating characteristics. All models produce high pressure-flow characteristics for stable operation. High discharge pressure provide for long hose lays, or steep up-hill pumping situations, with ample residual pressure at nozzle to generate the high velocities required for flat stream trajectory and effective penetration. The flow rate ranges accomodate teh several truck size installations most commonly used in the field.
