Protect Your Pump With a Powerful, Space-saving Monster Grinder

Is your sewer grinder pump running into large objects it just can’t handle? The Monster Industrial 1-HYDRO Open-channel grinder can cut through debris no matter its size, unlike a sewer grinder pump. Protecting a grinder pump and other downstream equipment is simple with a Monster Industrial grinder.

The 1-HYDRO Open-channel grinder is compact, yet tough on solids! It fits into areas with limited space requirements while still providing the necessary power for downstream protection. Two rows of hardened steel cutters rotate slowly and with incredibly high torque to grind large solids that flow through pumps and pipelines into small particles. Our sewer grinders are used by facility managers in thousands of towns and cities, nursing homes and hospitals. They also are used in digester and food waste applications.
