The V2 Series grinder from Pentair - Myers has a volute and impeller design that allows shut-off heads up to 180 feet with a single-stage centrifugal pump. This design gives operators the flexibility to change between the standard and high-head flow design by simply swapping the impeller and cutter plate, simplifying maintenance and reducing service parts inventory for low-pressure sewage systems projects. It has an optional quick-disconnect cord for easier servicing in the field, double-row bearings to absorb axial and radial loads, and an oil-filled motor for cooler operating temperatures and longer life. 888/987-8677; www.femyers.com.
