Volute
Remove the four nuts and lock washers from the volute studs. Remove volute and square ring from pump.
To remove or reverse the shredding ring, fi rst remove
the three fl at head allen screws. The screws are
installed with loctite so apply heat to screws before
removing, and lift the throat out of the body. The
shredding ring is press fi tted to the volute and must
be removed with an arbor press.
NOTE: After a number of years of service or if the shredding ring cutting edges dull, the ring can be
pressed out of the volute and reversed to utilize the opposite cutting edges. To maintain effi cient grinder
pump operation, care should be taken to keep both the radial cutter and shredding ring cutting edges sharp.
Neither part can be sharpened to renew the cutting ability. The radial cutter must be replaced and the
shredding ring either reversed or replaced.
