Remove the packing gland halves and the packing studs Loosen the stator support cap and rotate the suction housing stator and discharge flange together Replace the packing gland studs in the threaded hole provided CAUTION Rotating the suction flange by any other method may tear the stator gaskets causing a leak Once the gaskets have been compressed it is virtually impossible to rotate any one of the two compressing surfaces without tearing the gasket 2 6 Discharge piping diameter should generally be as large as the pump ports unless fluid conditions indicate otherwise An easily removable section of the piping one to two times longer than the connecting rod should be mated to the discharge port This will allow the stator to be removed without having to disassemble the complete pump 2 7 FOUNDATION Each unit should be mounted on a strong fabricated steel base plate The base plate should be mounted on a concrete foundation The foundation should be approximately 4 to 8 longer and wider than the base for which it is built See Figure 2 1 Anchor bolts for the base plate should be located in the foundation FOUNDATION DIMENSION BASE PLATE 100 TO 200mm base BASE PLATE DIMENSION SHIM AS ANCHOR BOLTS NECESSARY BASE PLATE WASHER CONCRETE 3 FOUNDATION g Je Check the base plate surface with a carpenter s level and place shims under the base plate at the places necessary to
