Grinder Systems

Protect Your Pump Station and Avoid Clogged Sewer Lines

With slow speed, high torque, and dual shaft design, municipal grade grinders augment pump stations to enable shredding of heavy to light solids such as wet wipes, paper towels, disinfecting cloths, plastics, and other long stranded or fibrous materials. For fish, meat, and poultry processing, industrial grade grinders macerate food solids with high performance cutters designed to keep pumps and pipes flowing smoothly. Jensen Precast packaged grinder vaults feature high quality precast concrete coupled with top of the line grinders for an easy to install solution. Inline models feature flow rates from 65 gpm to 2500 gpm. Open channel models offer flow rates up to 700 gpm. Custom design grinder vaults for any size project are also available.

How It Works

  1. Wastewater flows via gravity from a residential, business, or municipal source through underground pipes into the pump station wet well positioned at a lower elevation.
  2. To protect downstream pump stations and other critical civil infrastructure, grinder vaults serve as the onsite solution for reducing larger solids down to consistently passable sizes, thereby extending the life and maintenance cycles of all downstream equipment.
  3. When solids encounter an inline, open channel, or wall mounted dual shaft grinder, the serrated cutting teeth pull the solids into the machine and quickly reduce the size of the solids to a passable level by all downstream equipment.
  4. When the grinder encounters an impassable object, such as large metal waste or rocks, the grinder automatically reverses direction, kicking the solid back toward a rock trap where it can be collected later during a maintenance checkup on the system.
  5. The reduced solids then continue down the main sewer system, passing through all critical downstream infrastructure and providing owners and operators alike peace of mind that their underground sewer system will continue operating smoothly for years to come.
