Hale TPM Sistem User Manual

TPM SYSTEM INSTALLATION & OPERATION MANUAL

(Manual Part No. 101-0850-08-0)

RETROFIT

If you are retrofitting the TPM System to an older pump, call the
Hale Pump Service Department, with the pump Serial Number to
verify that the pump has the proper openings for the TPM System
before attempting retrofit.

PMD CONTROL VALVE

Cut the mounting holes in the truck panel as shown on Plate

1.
No. 742C. The new PMD Control Valve must be located higher
than the top of the midship pump to allow for proper drainage
.
Install the indicator bracket assembly (519-0071-10-0) to the

2.
PMD Control Valve by placing the slot in the bracket and
white pressure indicator over the pin in the PMD Control Valve.
The (4) mounting holes in the indicator bracket should align
with the tapped holes in the PMD Control Valve. The top view
of the PMD Control Valve with the indicator bracket assembly
installed is shown in Figure 1.

The PMD Control Valve assembly can now be mounted to the

3.
truck panel as shown in Figure 2. The PMD Control Valve
Assembly is installed on the inside of the truck panel while the
instruction plate is on the outside. Attach the instruction plate to
the PMD Control Valve Assembly using the (4) 3/4-20 x 5/8 Lg.
Phillips Head Screws (018-1205-44-0). Tighten securely.

Attach the adjusting handwheel (512-0070-00=0) to the PMD

4.
Control Valve Shaft using the screw (018-1214-45-0) and lock
nut (110-1205-11-0) provided. Turn the adjusting handwheel in
both directions to verify that the pressure indicator moves freely
to both extremes. If the pressure indicator does not move freely,
check for binding from the indicator lock nut (110-1008-06-0).
There should be approximately a 1/64-1/32 space between the
washer (097-0750-01-0) and the lock nut.

QG RELIEF VALVE

On new pumps, the QG (internal) relief valve is shipped completely installed. If you are installing a
TPM on a new pump, skip to the next Section, “PG30 Relief Valve

€ Sensing valve Assembly”. If you

are retrofitting, follow Steps 1, 2, 3, below:

The existing QD Relief Valve must be removed from the Midship pump body. Disconnect the old

1.
PM control tubing line. Disconnect the drain line if used. Disconnect the electric switch leads.
Remove the four 7/16” hex head capscrews holding the cover, switch bracket, and relief valve
in place. Remove the retaining ring holding the spring in place. Remove the spring and cast iron
cover. The brass cage with piston and valve stem must be removed from the pump. The best
method here is to CAREFULLY get pry bars under the lip of the cage, at the pump surface. Pry
the cage out, taking care not to mar any of the cast iron pump surfaces. The brass parts will all be
discarded, so do not be concerned about destroying them during the removal.

Once the brass parts are removed, the bore in the pump body MUST be cleaned to remove any rust

2.
or mineral deposits that may have accumulated on the machined surfaces. Use a wire brush and
emery cloth if required. Be sure these surfaces are PERFECTLY CLEAN before proceeding to
the next step, because they are o-ring sealing surfaces.

Locate the new QG relief valve assembly. Install the two large o-rings provided in the two grooves

3.
at the outside diameter, and coat these o-rings and pump bores with a general purpose grease
before inserting. The new valve must slide in smoothly. If it does not, clean the pump bore more
thoroughly. Once installed, rotate the valve so the compression tube fitting is locate UP and the red
cap plug DOWN. Attach with four 7/16-14 B 1-1/4 LG. hex head capscrews (018-1812-02-0) and
tighten to 48 ft. lbs. torque.

Instructions to install a replacement 200-2261-00-0 Indicator Light Switch. This switch is a

4.
proximity switch and senses the position of the piston and valve. Connect the leads of the switch
to a test light. The test light should be lit. Screw the switch into the 044-0122-00-0 cover. The
cover and the rest of the QG Relief Valve parts should be completely assembled. As the switch is
screwed into the cover, the test light will go off. Thread the switch in an additional 3/4 to 1-1/4
turns. The switch location is now set. Tighten the switch lock nut.

PG30 RELIEF VALVE & SENSING VALVE ASSEMBLY

1.

You must find an open discharge pad on the midship pump to
mount the PG30 Relief Valve and Sensing Valve Assembly. One
typical location is shown in Figure 3. Any available opening
can be used including any of the “four-bolt” openings on the top
of the pump if space permits. In deciding which opening to use,
remember that a 3” pipe line directing the water to the ground
must be threaded into the PG30 outlet flange. Note that the PG30
relief valve can be rotated into four different positions on any
given pump discharge opening.

Once you have determined the proper outlet and orientation,

2.
mount the PG30 relief valve using a greased gasket (046-0050­00-0) and, attach using the two “C” Washers (097-0440-00-0)
and four 7/16-14 x 1-1/2” I.G. hex head capscrews (018-1814­02-0). Tighten to 48 ft. lbs. torque.

The sensing valve (bolted to the PG30 relief valve) must now be

3.
checked for proper orientation. Regardless of where the PG30
is mounted on the pump, the sensing valve must be bolted to a
boss on the SIDE of the relief valve, NOT the top or bottom. In
addition, the connections marked “A” and “PM” must point “UP”
as shown in Figure 4. The sensing valve is moved or rotated
by removing the 7/16” capscrew shown, and reinstalling after
it is in the proper orientation. NOTE that this “UP” position is
CRITICAL to the proper operation of the TPM System.

Attach the switch/flasher bracket to the PG30 relief valve cover

4.
as shown in Figure 5. This is done by removing two of the cover
capscrews opposite each other. Reinstall the capscrews and
washers securing the switch bracket as shown. Adjust the bolts in
the side of the bracket until the switch plunger is depressed in the
normal position shown. Tighten all bolts securely.
