Fit VOLUTE LINER (MMVOL) – Gently place Volute Liner over Impeller so that it cannot drop down
and cause injury. Move it back towards Frame Plate until the conical bore engages with the matching
periphery of the Frame Plate Liner Insert. Ensure that the Volute Liner Seal (‘O’ Ring) has not been
displaced. Fit a G clamp to temporarily clamp the Volute Liner discharge nozzle to the flange of the
Frame Plate, as shown in Fig 11.
NOTE: THIS WILL PREVENT DROPPING THE VOLUTE AND CAUSING POTENTIAL
INJURY OR DAMAGE.
