TASKMASTER® TM8500 Wastewater Grinder
TASKMASTER® TM8500 Wastewater Grinder
The TASKMASTER® TM8500 Wastewater grinder uses a twin-shaft mechanism and CUTTER CARTRIDGE® technology to continuously reduce solids within pressurized pipeline systems, protecting downstream pumps and equipment.
Two stacks of intermeshing cutters aggressively pull the solids in and finely reduce them. These grinders can be installed in gravity or pressurized, vertical or horizontal pipe systems, on the suction or discharge side of a pump. The TASKMASTER® is provided with CUTTER CARTRIDGE® technology, wherein 6 cutter disks and 6 spacer disks are replaced by one-piece elements for far greater strength, fewer components, no stack loosening or stack re-tightening requirement.
Further advantages include:
- Suitable for piping up to 300mm
- Suitable for flows to 75 L/s
- Hardened alloy steel cutters
- Low-speed, high torque cutting
- Cutter Cartridge Technology
