Equipment Protection With a Space-Saving Monster In-line Grinder

The 1-HYDRO In-line Monster grinder provides complete protection for downstream equipment – in a small package. Packed with power, this inline sewage grinder converts the 2, 3 or 5 hp (1.5, 2.2 or 4 kW) motor into a cutting force ready to keep fluids flowing through pumps, valves, centrifuges and heat exchangers. Two rows of sharp, steel cutters rotate slowly and with incredibly high torque to break down solids in sewage, sludge and slurries. The 1-HYDRO easily bolts into the pipeline and can be mounted in any orientation. The 1-HYDRO is an economical solution for lower flow applications. Its small package makes it ideal for protecting sewage pumps in office buildings, apartment complexes, resorts and retail centers. It works well in food processing plants, protecting systems in waste streams. 1-HYDRO In-line grinders are also found in digester, manure processing and food waste applications to protect processing systems or breakdown feedstocks.
