Maintenance
CAUTION:
The impeller and wear-ring clearance setting procedures must be followed. Improperly setting the
clearance or not following any of the proper procedures can result in sparks, unexpected heat
generation, and equipment damage.
10. Measure the total indicated runout (TIR) on the impeller wear rings, center sleeve, throttle
sleeve, diaphragm sleeve, and bearing fits. The shaft is the datum point; measure the
runout of wear rings and impeller nuts to the shaft with a dial indicator.
API limits are listed in the Shaft and rotor runout requirements table.
Install the rotating element
1. Fit the casing gasket (351) around all the hydraulics, bores, and through holes using the
upper half as a template.
Pay particular attention to the area around the seal chamber face. This is a critical area for
proper sealing. Make sure that the gasket extends all the way to the face but does not
protrude past this face. Use a file to make the face clean and flush.
Sheet-gasket thickness is 1/32 in. (0.8 mm) for pump sizes 3x4-8B, 3x6-9/10, 4x6-10, and
4x6-11. For all other pumps, the thickness is 1/64 in. (0.4 mm). Applicable gasket materials
are Garlock Style 3000 or Flexitallic SF 3500.
2. Assemble all casing studs (356A, 356C, 356K).
