Maintenance and Repair
6-6 Stainless Max Series Pumps
IMPORTANT!
WHEN REASSEMBLING, ALL COMPONENTS MUST BE CLEAN AND
FREE OF DEFECTS.
❑ Wherever there is a requirement for new parts, it is
recommended to use only Hale authorized replacement parts for
optimum safety of the equipment and its operators.
❑ Wherever gaskets are removed, the gasket must be replaced.
Clean all gasket material from mating surfaces before installing
a new gasket. Be careful not to score the finished surfaces.
❑ Bearings and seals should be inspected whenever the parts are
disassembled.
●
Bearings and other components should be cleaned using only
recommended solvents.
●
Inspect bearings for wear, pitting, and damage.
●
Lightly oil or grease the shaft, O-ring seals and bearings
before installing bearings and spacers, especially when
pressed-in.
❑ Inspect the gear tooth surface for wear damage and pitting.
Replace all components that are worn, damaged, or pitted.
❑ When inspecting the impellers and clearance rings for wear,
measure the impeller hub diameter and the inner diameter of the
clearance ring, using a digital caliper. If measurements indicate,
replace clearance rings and impeller. See Figure 6-3: “Critical
Dimensions” on page 6-2.
❑ It is recommended to replace O-ring seals to avoid unnecessary
downtime later on.
❑ Replace any hardware that shows signs of excessive wear.
Note: If either the impeller hub or clearance rings are out of tolerance,
both rings and the impeller must be replaced, as well as the
mechanical seal.
