4. PUMP OVERVIEW
All Hale Flex Series single stage booster pumps feature an integral gearbox and a self-adjusting me-
chanical seal and are volute style centrifugal pumps. The AP, CBP, and MBP pumps provide one inlet
and one outlet. The RSD provides an additional auxiliary side discharge (see Figure 4), typically used
to provide mounting for a TRV or an anode.
Figure 4. Hale Booster Pump Inlet And Outlet
Standard construction includes a bronze impeller and wrap around wear rings in an iron pump body.
All bronze construction is an option. The pumps are designed for water and need an external primer
(to evacuate air) to pump water from a static source. All Hale Flex Series single stage booster pumps
support outlet rotation, see Table 1 for the applicable drawing. The drawings are located on the flash
drive provided with the pump or on the Hale Products website (www.haleproducts.com).

assessment of operations when installing a Hale booster pump on firefighting apparatus.
5.3. Special Tools
Observe all torque requirements and see FSG–MNL–00184, Technical Manual For Hale Single Stage
Booster Pumps for additional information. When conducting testing/verifications for installation pur-
poses, bearings temperatures can be checked using an infrared thermometer.
5.4. Mounting A Hale Booster Pump
A PRESSURE HAZARD MAY EXIST EVEN WHEN THE PUMP IS NOT RUNNING. PRIOR TO
REMOVING HOSES, OR CAPS FROM PUMP CONNECTIONS, RELIEVE PRESSURE BY OPEN-
ING DRAINS. BLEEDER VALVES SHOULD ALSO BE USED WHEN CONNECTING TO AN IN-
TAKE FROM PRESSURIZED SOURCE.
ALWAYS STOP THE ENGINE, SET THE PARKING BRAKE, AND CHOCK THE WHEELS BE-
FORE GOING UNDER THE TRUCK FOR ANY REASON.
OPEN AT LEAST ONE DISCHARGE VALVE SLIGHTLY TO PREVENT THE PUMP FROM OVER-
HEATING. IF THE PUMP RUNS COMPLETELY CLOSED, IT MAY HEAT THE WATER ENOUGH
TO SCALD A PERSON.

THE PUMP SHIFT CONTROL AND PUMP SHIFT INDICATOR SYSTEM ON THE APPARATUS
MUST BE INSTALLED IN ACCORDANCE WITH MANUFACTURERS INSTRUCTIONS AND
REGULATIONS SUCH AS NFPA.
BEFORE LAY OUT AND INSTALLATION OF THE DRIVELINE, CONSULT APPARATUS AND/OR
DRIVELINE COMPONENT MANUFACTURER FOR GUIDANCE AND REFER TO HALE SB90
FOR ALIGNMENT OF DRIVESHAFT AND PUMP DRIVE.
DO NOT EXCEEDING POWER TRAIN LIMITS WHEN INSTALLING A PUMP. A MEANS TO
CONTROL THE ENGINE OUTPUT WHEN PTO IS ENGAGED SHOULD BE CONSIDERED.
FAILURE TO INSTALL THE ENGINE SPEED INTERLOCK SYSTEM PROPERLY MAY RESULT
IN PTO DAMAGE.
HALE PUMPS ARE SHIPPED WITHOUT OIL. FILL GEARBOX WITH FLUID LISTED IN TABLE 5

OPEN AT LEAST ONE DISCHARGE VALVE SLIGHTLY TO PREVENT THE PUMP FROM OVER-
HEATING. OVERHEATING CAN DAMAGE THE PUMP SEAL, AND OTHER PUMP PARTS.
Figure 6 shows the recommended mounting brackets an OEM should provide to mount a Hale Flex
series single stage booster pump. (Hale does NOT supply mounting brackets.) Mount a pump using
both the pump body and the gearbox. Refer to the applicable pump model and installation sheet of
the drawing for mounting details and dimensions as follows.
• FSG–PL–01481 • FSG–PL–01486
•FSG–PL–01482 •FSG–PL–01487
• FSG–PL–01483
Figure 6. Typical Booster Pump Mounting

Design the installation with consideration NOT to transmit loads or twisting moments (AKA angular
mass or rotational inertia) to (or through) the pump assembly from the apparatus (chassis, frame,
bodywork, or suction and discharge piping connections). In addition, DO NOT USE THE MOUNTING
HARDWARE to eliminate voids between the bracket(s) and the pump body or gearbox mounting fac-
es. If the bracket(s) do not align with the pump/gearbox machined surfaces, reposition the bracket(s)
(or use shims/spacers) to ensure the mounting does NOT twist the pump/gearbox.
Attach the OEM provided primary rigid support bracket to the pump body. For an AP, CBP, or RSD use
a minimum of three (3) pump body-mounting bosses (CBP and AP) or studs (RSD). For an MBP use a
minimum of four (4) pump body-mounting bosses. The pump body-mounting bosses require SAE
grade 8 (or better) fasteners to attachment to the bracket(s) (The fasteners are NOT supplied by
Hale.)
Attach an OEM provided secondary support bracket to the gearbox using a minimum of three (3)
gearbox metric mounting studs. (The drive side of the gearbox provides ten (10) M10–1.5 threaded
holes.) Hale supplies four (4) M10 studs, flat washers, lock washers, and nuts to secure the OEMs
mounting bracket(s) to the gearbox.
When mounting a Flex series pump, provide easy access to the lubrication maintenance points on
the gearbox (drain, fill, and sight glass). The gearbox drawing FSG–PL–01481, Sheet 5 shows the
gearbox lubrication points. The drawing can be found on the flash drive provided with the pump or on
the Hale website (www.haleproducts.com).
The drive shaft from the PTO to the pump should conform to the driveline manufacturers require-
ments and typically has an angle of 4 degrees or more with cardan type shafts. CV type shafts have
their own criteria and the supplier of the driveline should be consulted for proper installation. Hale
bulletin (SB90) also address best practices for driveline angles and installations. This bulletin can be
found on the flash drive provided with the pump or on the Hale website (www.haleproducts.com).
Follow PTO manufacturers guidelines for pump drive. Mass moments of inertia can be found on the
Hale drawings (typically on Sheet 1).
Support valves and pump plumbing to minimize the loads on the pump assembly.
5.4.1 Hardware Requirements
Do NOT install used (reuse) nylon type self-locking hardware.
5.4.1.1 Mounting Hardware
PUMP ASSEMBLY HAS BOTH METRIC AND SAE HARDWARE
SAE grade 5 or metric class 8.8 (or better) bolts are required for all mounting hardware. Grade 8 re-
quired fasteners are specified for specific locations, see paragraph 5.4, Mounting A Hale Booster
Pump. All fasteners should be installed with a locking anaerobic adhesive/sealant, see para-
graph 5.4.3.2, Thread Lock, Bonding. See Figure 7 to identify grade 5 (or class 8.8) bolts from their
markings.

5.4.3 Booster Pump Drains
Hale Flex Series single stage booster pumps provide NPT threaded ports for drain installation. Use
care to ensure water is not trapped in drain plumbing. Trapped water could cause damage in freez-
ing temperatures.
5.4.4 Priming Connections
Air must be pulled out of the suction plumbing leading to the pump at the highest point. Installations
that have multiple high points will need multiple priming connections to make sure all the air is re-
moved from suction piping during priming.
