VR1 / VR2 Grinder Pumps Information

A. Wide Angle Float Switch F. Shaft Seals • Piggy-back cord for easy maintenance • Oil lubricated single carbon and ceramic faced seal provides motor protection B. Cable Entry System G. Impeller • Cable jacket sealed by compression fitting and individual wires sealed by compression grommet for double seal protection against water ingress • Semi-open impeller handles ground slurry without clogging or binding • Pump-out vanes help keep trash from seal and reduces pressure at seal face for longer life C. Oil-Filled Motor H. Axial Cutter System • Maximizes heat dissipation and provides constant bearing lubrication for long life • High torque start/run capacitor for single phase motors for assured starting under heavy loads. • Internal capacitors eliminate need for control panel • Easily slice through solids and trash commonly found in domestic wastewater without roping or clogging • Constructed of 440 SST hardened to 57-60Rc for long life • Easily replaceable without dismantling pump D. Integrated Heat Sensor I. Volute Case • Cast iron, 1-1/4” vertical, flanged discharge (VR2) • 2” vertical discharge (VR1) • Protects motor from burnout due to excessive heat from any overload condition. Automatically resets when motor has cooled E. Shaft and Fasteners • Stainless steel for maximum corrosion resistance and long life
