The Monolithic Vibrating Screen Vibrating Screen — Vibrating Screen mounted on top of the EHP 1500. Also compatible with the EHP 2000. Rubber isolators between the screen and the hopper provide optimum vibration from the screen because the vibrator is designed to vibrate the screen and not the pump. New and Improved — Introducing our new and improved screen! Its added hook at the end of the of the angle iron allows the screen to be stood upright on either end of the hopper. The screen for the small pump can only be stood on one end.. In use — The Vibrating Screen will filter out rocks that are too large for pumping through a shotcrete pump. Crisis Averted — This screen does it’s job by filtering out of aggregate that is too large for pumping. (Javier Figueroa)
