A Hale pump is a quality product; ruggedly designed, accurately ma-

chined, carefully assembled and thoroughly tested. In order to maintain

the high quality of your pump and to keep it in a ready condition, it is im-

portant to follow the instructions on care and operation. Proper use and

good preventive maintenance will lengthen the life of your pump.

OPERATION The following instructions apply when the pump is to be put into operation immediately after arrival at the fire. If standing by without pumping, the pump should not be engaged. WORKING FROM HYDRANT 1. Close all discharge valves and drain valves. 2. Open and flush hydrant. Attach hose from pump to hydrant. Open hydrant. 3. Bleed air from supply hose 4. With engine at idle, engage pump. 5. Open discharge valve. 6. Increase engine throttle gradually until desired pressure is reached.
PAGE 4
5. Open throttle gradually until the desired pressure is reached. Regulate valve for cooling engine and set the pressure governor or relief valve. As the throttle is opened, the pressure should build up as the engine speed increases. Should the engine speed go up without a corresponding increase in pressure, the pump is cavitating or “running away” from the water. There are two possibilities that can lead to this condition. a. The first can occur only on high vertical lifts with several short lines.
PAGE 5
When working from draft, do not pump volumes large enough to cause a whirlpool at the strainer. This will allow air to get into the pump and result in rough operation and pulsation. If more water is needed, try to get a better submergence for the strainer. LUBRICATION PEDESTAL The pump shaft bearings are supplied with oil from the pedestal housing. Use a premium grade of multirange SAE EP-90 oil. Fill to oil level plug. Do not use a heavier oil or too much oil. Drain oil and renew every six months.

5. To remove impeller, put a flat pry bar on each side of impeller between it and pump head. The pry bars should bear against impeller disc opposite the impeller vanes. Tap end of shaft with a soft hammer, while maintaining pressure on pry bars, until impeller comes off. Do not put too much pressure on the pry bars. Application of heat may be necessary. Use a torch to slowly heat the impeller hub area until the impeller comes loose. Remove the impeller lock nut (or capscrew and washer) and impeller.

GAUGES & LAYOUTS To accurately test a pumper for performance, a pitot gauge and a pump pressure gauge, both gauges tested for accuracy, are required. Gauge testing can be done with a dead weight gauge tester. Pumpers should be tested from draft at not over a 10 foot lift with 20 feet of suction hose. 1500 GPM and higher rated pumpers frequently require two separate 20 foot lengths of suction hose and larger pumps utilize lower lifts down to 6 feet.
PAGE 8
TESTING PRESSURE The pumper should now be checked at 7/10 capacity at 200 PSI, and 1/2 capacity at 250 PSI. If the apparatus fails to pump its required volume at either 200 or 250 PSI, it should be thoroughly checked. Compare results with performance of the pumper when new. An appreciable drop indicates need for service. ENGINE SPEED Engine speed is important on all four tests and should be recorded, and compared to the original speeds at time of delivery.

2. Air Leaks. A frequent cause of low performance, recognized by excess motor speed, hose pulsation and unsteady pressure gauge. Remedy - check pump for holding vacuum, find leaks. Sometimes these leaks are in the booster tank plumbing. Leaks can usually be heard when the motor is stopped. See instructions. Priming will be delayed by an excessively leaking packing gland. 3. Suction obstructions. These cause higher than normal engine speed and reduced capacity.
PAGE 10
the greater the pressure at which the pump is operating, the larger will be the bypass and the more the performance will be reduced. When new, the clearance between the impeller hubs and the ring is approximately five to nine thousandths of an inch per side (.005-.009). Any increase will allow more bypass and lower performance, but when the pump is adequately powered, it should not be necessary to replace clearance rings and impellers until the average radial clearance reaches 15 to 20 thousandths or more.

ADDITIONAL TROUBLESHOOTING CHARTS Table 4-1 lists the symptoms of some common problems and possible corrective measures. Before calling Hale or a Hale authorized parts service center for assistance, eliminate problem causes using Table 4-1. If you cannot correct a problem, please have the following information ready prior to calling the Hale Customer Service Technician Department for assistance. Customer Service Number: 610-825-6300.
PAGE 12
CONDITION Automatic Transmission With Power Shift System (continued) POSSIBLE CAUSE Air leaks in shift system SUGGESTED CORRECTION Check system for loss of air. Check of leak in system. Employ manual override procedures if necessary. See Standard Transmission with Power Shift System. Attempt to locate and repair leak(s). Leakage, if external, may be detected audibly. Leakage could be internal and not as easily detected.
PAGE 13
CONDITION PUMP LOSES PRIME OR IT WILL NOT PRIME (CONTINUED) POSSIBLE CAUSE Air Trap in Suction Line SUGGESTED CORRECTION Avoid placing any part of the suction hose higher than the suction intake. Suction hose should be laid with continuous decline to water supply. If trap in hose is unavoidable, repeated priming may be necessary to eliminate air pocket in suction hose. Pump Pressure too low when nozzle is opened Prime the pump again and maintain higher pump pressure while opening discharge valve slowly.
PAGE 14
CONDITION INSUFFICIENT PUMP CAPACITY INSUFFICENT PRESSURE POSSIBLE CAUSE Insufficient engine power SUGGESTED CORRECTION Engine power check or tune up may be required for peak engine and pump performance. Transfer Valve not in proper “Volume” position TWO STAGE PUMPS ONLY. Place transfer valve in “Volume” position (parallel) when pumping more than 2/3 rated capacity. For pressure above 200 PSI (13.8 BAR), pump should be placed in “Pressure” (series) position.
PAGE 15
CONDITION LEAK AT PUMP PACKING REMOTE CONTROL DIFFICULT TO OPERATE ENGINE SPEEDS TOO HIGH FOR REQUIRED CAPACTICTY OR PRESSURE RELIEF VALVE DOES NOT RELIEVE PRESSURE WHEN VALVES ARE CLOSED POSSIBLE CAUSE Packing out of adjustment or worn. Lack of lubrication SUGGESTED CORRECTION Adjust the packing per the procedure in Section 3 of this manual (8 to 10 drops per minute leakage at 150 PSI (10 BAR) preferred). Replace pump packing per Section 3 of this manual.
PAGE 16
CONDITION RELIEF VALVE DOES NOT RECOVER AND RETURN TO ORGINAL PRESSURE SETTING AFTER OPENING VALVES RELIEF VALVE OPENS WHEN CONTROL VALVE IS LOCKED OUT UNABLE TO OBTAIN PROPER SETTING ON RELIEF VALVE WATER IN PUMP GEARBOX POSSIBLE CAUSE Dirt in system causing sticky or slow reaction Drain hole in housing, piston, or sensing valve blocked Wrong procedure SUGGESTED CORRECTION Relief valve dirty or sticky. Follow instructions for disassembling, cleaning, and lubricating. Blocked relief valve.

EXPLANATION OF TERMS CENTRIFUGAL PUMP A centrifugal pump consists of an impeller with an intake at the center, so arranged that, when rotated, it will discharge water by centrifugal force into a casing or volute body which surrounds the impeller. The water exits from the impeller at high velocity into the diverging passages of the volute body, where the velocity, energy is converted into pressure.
PAGE 18
PRESSURE GAUGE The pressure gauge is usually graduated in pounds per square inch and/or bar. It is connected to the pump discharge manifold, thus indicating the pump discharge pressure. COMPOUND GAUGE The compound gauge is graduated to read pressure in pounds per square inch and/or bar with the vacuum in inches of mercury and/or bar. It is connected to the pump suction thus indicating the suction pressure when pumping from a hydrant or the vacuum when pumping from draft.

Pump Maintenance Check List Truck Manufacturer________________________________ Pump Model & Serial Number_______________________ Year_________Unit#_______________________________ RECOMMENDED WEEKLY PROCEDURES (Not applicable to HFM, PSD or CSD pumps) ¨ Test relief valve system or governor at 150, 200, 250. If pump is equipped with TPM you will need to have positive pressure. ¨ Test transfer valve (if applicable) ¨ Test the priming system and check lubrication level in priming tank.
