HALE AP, Technical Manual

The two Maintenance sections provide all aspects of maintaining the AP, CBP, MBP, and RSD
pumps, including sparing, preventive and corrective maintenance (which includes troubleshoot-
ing and remove and replace instructions). Notice that the use of this manual also requires
maintenance personnel to have received Hale training prior to using it. Use Hale Training Acad-
emy (Pumping And Maintenance) training (see paragraph 1.3, Training) and the two Maintenance
sections for all aspects of maintaining the pumps.
Within the two Maintenance sections, the troubleshooting provided utilizes SCR tables which
provide the list of known symptoms associated with a pump trouble/problem/failure. To use a
SCR table, locate the indicated SYMPTOM, verify the associated CAUSE (the maintainer must ver-
ify ALL the associated causes if multiple causes are listed) and then perform the associated
REMEDY (or remedies). The R&R procedures provide pump removal from the apparatus via two
separate methods: removing a pump as a complete assembly or removing only the pump portion
leaving the gearbox in the apparatus. Once removed the subsequent pump or gearbox repairs
are treated as bench procedures each covering a specific level (1, 2, 3, or renewal) of mainte-
nance. Each level of maintenance requires the associated repair kit be utilized. Utilizing the as-
sociated repair kit ensures all the required components are available for replacement. Utilizing
the repair kits as intended prolongs pump performance and supports the manufacturer’s warran-
ty.
Performing a procedure is NOT the ONLY key action in maintaining a pump, documentation of the
pumps Preventive Maintenance, R&R, and SYMPTOM/REMEDY history (including meaningful
tracking of when each issue occurred) is also key to maintaining each pump. A maintenance log
with meaningful entries will provide invaluable insight, time/money savings (in reduced down
time and shorted troubleshooting time), and cost savings over the life cycle of each pump.

Pump Specifications And Numbering
Hales policy is one of continuous development. Hale therefore reserves the right to amend speci-
fications without notice or obligation. Refer to Section 2.2, Pump Specifications And Numbering,
in the Hale OIM manual (FSG–MNL–00183) for serial number locations, model number defini-
tions, and major pump features. Refer to the Hale Products website (www.haleproducts.com) for
detailed booster pump specifications. NOTE: Using your pumps serial number and the Hale web-
site (or Customer Service) is the best way to ensure you receive/utilize the correct replacement
parts for your pump.

Principles Of Operation
Hale booster pumps are centrifugal pumps that operate on the principle that centrifugal force is
created by a rapidly spinning disk. Figure 1 shows an amount of water has been placed at the
center of a disk. The disk is rotated and the water is thrown outward from the center to the edge
of the disk. The velocity at which the water travels from the center directly relates to the diameter
of the disk and the speed of rotation. When water is confined in a closed container (such as the
volute), the velocity is converted to pressure; pressure is therefore, dependent on the speed of
rotation.
