SECTION V MAINTENANCE
AND REPAIR
OVERVIEW
This section describes the removal, inspection,
and re-installation (as required for maintenance
and repair) of all booster pump components. To
completely disassemble the pump and gearbox,
follow the disassembly instructions in the order
which they appear in this text. At any point in the
disassembly process, the pump may be
reassembled by following the instructions
backwards through this manual.
NOTE: Unless otherwise indicated, these
instructions apply to all Hale booster pumps.
General Repair Guidelines
1. Match mark or note the orientation of
components before disconnecting or
removing them.
2. Where grease is called for, use a Lithium
Based Grease with 1 to 3% Molybdenum
Disulfate. The following are examples of
approved greases:
o
Dow Corning BR2-PLUS
o
Lubriplate Fiske #3000
o
Shell Super Duty Grease
o
Imperial #777
o
Mobil Grease Special
o
Sunoco Moly #2EP
3. In the gearbox, use only oil with an API GL-5
rating. Use SAE EP-90, 80W-90 or
synthetic 75W-80 oil. (See Table 5-1 for
gearbox oil capacities.)
4. Before installing the mechanical seal, use
the alcohol swabs provided by Hale
Products Inc. to clean all grease or oil from
the pump shaft and bearing housing.
5. Use only PAC-EASE Rubber Lubricant
Emulsion (or equal) on the rubber
mechanical seal parts to ease installation.
USE OF ANY OTHER LUBRICANT CAN
DAMAGE THE MECHANICAL SEAL AND
SEAT.
6. Replacement steel fasteners, must be grade
5, 360 O nylon patchlock fasteners. Apply
Loctite™ 242 (or equal) to all threads.
7. Before working on the pump, disconnect the
suction and discharge piping and drain the
pump body. Disconnect cooling tubes from
the water manifold and pump as required.
8. Label and disconnect all wiring from the
pump.
Cleaning and Inspection Guidelines
Wherever the procedures call for cleaning and
inspection, these guidelines should be followed:
1. Inspect all components for excessive or
abnormal wear.
2. Wherever a requirement for new parts is
indicated, obtain new components from Hale
Products Inc.
3. Wherever procedures call for the removal of
gaskets, the gasket should be replaced.
Clean all gasket mating surfaces before
installing new gaskets.
4. Bearings and other components should be
cleaned using only recommended solvents.
5. Bearings and seals should be inspected
whenever the parts are disassembled. Look
for signs of excessive wear.
