2Introduction

2.1 ESP PRIMER PUMP

Hale recommends and uses Rotary Vane Positive Displacement pumps (ESP) for priming. Priming pumps are used to evacuate air in the suction hose and pump. (See Figure 2-1: “Rotary Vane ESP Priming Pump.”)
Introduction ❑
ESP Primer System I nstruction Guide p/n: 029-0810-01-0
Figure 2-1: Rotary Vane ESP Priming Pump
The Hale ESP series priming pump is an environmentally friendly primer that does not require a separate lubricant reservoir.
The vanes and pump body are self-lubricating for maintenance free opera­tion. An ESP priming pump also uses a single control to open the priming valve and start the priming motor.
Note: For an optional “ESP Primer lubricated system,” also see heading “Lubri­cated ESP Primer System” on page 14.)
Hale priming valves open when the priming pump is operated allowing the air to escape from the pump. Two priming valves offered:
a. Semi-Automatic Priming Valve (SPV / SPVR) - also see heading “SPV
Priming Valve” on page 12.
b. PVG Priming Valve - also see heading “PVG Priming Valve” on page 14.
11
❑ Introduction

2.2 SPV PRIMING VALVE

The Hale Semi-Automatic Priming Valve (SPV) simplifies the priming opera- tion of your pump allowing for a faster priming time and longer primer life . The SPV is a diaphragm-operated valve that opens using the vacuum gen- erated by the priming pump.
Easily activated by a push button control, the SPV starts the primer motor creating a vacuum. The vacuum acts on the diaphragm in the valve causing the port to open allowing vacuum. (See Figure 2-2: “SPV Overview.”)
12
Figure 2-2: SPV Overview
The SPV conforms to NFPA requirements for priming time and hydrostatic test when bolted to Hale Midship series pumps. Each valve is factory tested to 26 in. (660 mm) hg. vacuum and 600 PSIG (41 BAR)
Overview
The SPV mounts directly to the priming connection of Hale Midship series pumps. Additionally, a universal adapter is available to mount the SPV on Hale Booster and Volute series pumps. The installer must also supply hose connections from the adapter to the pump priming connection.
When used on a midship fire pump, the valve mounts to the pump body with two studs and nuts, standard strainer and seal ring.
A short length of 3/4” (19 mm) ID vacuum hose connects the SPV to the priming pump, eliminating potential leak points in the priming hose.
ESP Primer System Instruction Guide
p/n: 029-0810-01-0
Introduction ❑
The short length of hose also allows for a faster priming time and longer primer life by reducing the volume that must evacuated.
The priming pump motor is push-button operated, located on the pump operator panel of the apparatus. There are NO hose connections at the pump operator panel thus saving valuable space.
Depressing and holding the PRIME push button energizes the priming pump motor creating a vacuum in the 3/4” (19 mm) ID hose. As sufficient vacuum is created the diaphragm depresses the spring to OPEN the prim­ing valve, thus creating a vacuum in the main pump body, priming the main pump. Once primed, as indicated by water discharging to the ground from the priming pump outlet, the push button is released to STOP the priming pump. The SPV then CLOSES for normal pump operation.
Configuration Options
The Hale SPV is available from the factory in four (4) different configura­tions. A description of each follows, beginning on the next page.
Retrofit Kit Option
The retrofit kit contains the components necessary for installing the Hale SPV on a midship fire pump. The kit contains a Hale SPV Valve assembly, panel placard and push button switch.
Universal Mount Installation Kit Option
The Universal Mount Installation Kit contains the components necessary for installing the Hale SPV on a volute or booster type pump. The kit contains a Hale SPV Valve assembly, universal mounting adapter, panel placard and push button switch.
Midship Pump Mounted Option
This option mounts the Hale SPV to the priming flange connection on a “new” midship pump body. Components included with this option and shipped with the midship pump are the push button switch, panel placard and Installation Manual.
When completing the apparatus installation of the Hale SPV, the priming pump must be mounted on the apparatus with the vacuum hose connected in addition to the push-button switch and panel placard being installed on the operator panel.
ESP Primer System I nstruction Guide p/n: 029-0810-01-0
13
❑ Introduction
Primer Mounted on Midship Pump
This option mounts the Hale SPV to the priming flange connection on a “new” midship pump body with the priming pump mounted to the pump gearbox. When this option is ordered, the vacuum hose is connected from the Hale SPV to the priming pump.
Components included with this option and shipped with the midship pump are the push button switch, panel placard and Installation Manual.
When completing the apparatus installation of the Hale SPV with this option the push-button switch and panel placard must be installed on the operator panel.

2.3 PVG PRIMING VALVE

The PVG is a combination valve and switch and is mounted on the pump operator’s panel. (See Figure 2-3: “PVG Priming Valves.”)
Figure 2-3: PVG Priming Valves
Pulling the handle out OPENS the valve and energizes the primer motor. Pushing the handle in de-energizes the primer motor and CLOSES the valve.

2.4 LUBRICATED ESP PRIMER SYSTEM

The Hale ESP Priming System has a proven history of reliable fast priming and high vacuum performance when properly maintained and operated in accordance with the instructions found in your Pump Installation, Operation and Service Maintenance Manual and in this guide. Under NORMAL oper­ating conditions (standard climates) our research has found that no lubri­cant is required.
14
ESP Primer System Instruction Guide
p/n: 029-0810-01-0
Introduction ❑
Figure 2-4: Typical ESP Lubricated System
The Hale ESP Priming System can be converted to a “lubricated system” by installing “separate” lubricant and discharge tanks and using a Propylene Glycol / water mixture as the lubricant. (See Figure 2-4: “Typical ESP Lubri­cated System.”)
Propylene Glycol is a less toxic and more environmentally-friendly coolant and is recommended over Ethylene Glycol based antifreeze.Propylene Gly­col (PG) based antifreeze provides comparable system protection to that of conventional ethylene glycol (EG) based coolants (i.e., freeze, and corro­sion protection).
Propylene glycol is readily available in automotive supply stores, under the following brand names:
❑ Sierra Antifreeze – use a 50 – 50 mix (www.sierraantifreeze.com)
❑ RV & Marine Easy Going Antifreeze, Camco Mfg. – use pure, DO NOT
mix. (www.camco.net)
A 50/50 blend of propylene glycol coolant and water has a freezing point of
-26° F (-32° C) and is applicable under most operating conditions.
ESP Primer System I nstruction Guide p/n: 029-0810-01-0
If a lower temperature protection is required, it can readily be achieved by increasing the coolant. (See Chart 2-5: “Typical Freeze-Up Protection,” on page 16.)

IMPORTANT!
IF THERE IS PRIMER LUBRICANT IN THE RESERVOIR, IT IS RECOMMENDED TO OPERATE LUBRICATED PRIMING SYSTEMS WEEKLY TO CYCLE THE FRESH LUBRICANT THROUGH THE PRIMER.
HOLDING THE PRIMER ON FOR TWO (2) OR THREE (3) SECONDS AFTER A PRIME FROM DRAFT WILL CLEAN OUT RESIDUE IN THE PRIMER.

4 Primer Operation

THE PROCEDURES IN THIS SECTION ARE GENERAL OPERATING PROCE­DURES. NOT ALL PROCEDURES IN THIS SECTION MAY APPLY TO YOUR SPE­CIFIC OPERATIONAL REQUIREMENTS.
THESE PROCEDURES DO NOT REPLACE THE PROCEDURES, POLICIES OR GUIDELINES ESTABLISHED BY THE AUTHORITY HAVING JURISDICTION, NOR DO THEY REPLACE THE RECOMMENDATIONS AND PROCEDURES PROVIDED IN THE APPARATUS MANUFACTURER'S MANUAL.
ALWAYS REFER TO THE PROCEDURES PROVIDED BY THE AUTHORITY HAV­ING JURISDICTION FOR OPERATING PROCEDURES, SETTING WHEEL CHOCKS, AS WELL AS LAYOUT AND CONNECTION OF HOSES, VALVES AND DRAIN COCKS. ALL VALVES, DRAIN COCKS AND CAPS SHOULD BE CLOSED.
Operation ❑
WARNING !

4.1 PRIMING THE PUMP

1. Position the apparatus as close to the water source as practical. The pump can draw 100% of its rated capacity with less than a 10 foot (3.05 meters) vertical lift and 20 feet (6 meters) of suction hose.
2. Activate the priming pump - pull the control handle, or press the push button.
Your departmental manual for pumping should specify the correct RPM for priming. However, in general, priming should be operated at IDLE.
Running the engine at speeds higher than 1,000 RPM during priming is not recommended. It does not improve the priming operation but can cause damage to the pump.
CAUTION !
IF THE DISCHARGE GAUGE READING DOES NOT INCREASE, THE INTAKE GAUGE READING DOES NOT FALL BELOW ZERO (0), OR THE PRIMING PUMP DOES NOT DISCHARGE WATER WITHIN 30 TO 45 SECONDS, DO NOT CONTINUE TO RUN THE PRIMING PUMP.
ESP Primer System Instruction Guide p/n: 029-0810-01-0
STOP THE PUMP AND CHECK FOR AIR LEAKS OR POSSIBLE PROBLEMS. SEE SECTION 6 “TROUBLESHOOTING,” ON PAGE 47.
33
❑ Operation
3. Monitor the intake and discharge master gauges. When the pump is primed, the intake reading falls below zero (0), and the discharge pressure starts to increase. You may also hear or see water discharging from the primer, indicating the pump is primed.
4. Gradually open the discharge valve until water emerges in a steady stream. Then open the other discharge valves to the desired setting.
5. Gradually open the engine throttle until the desired pressure or flow is achieved.
CAUTION !
DO NOT CAUSE A WHIRLPOOL AT THE STRAINER. THIS ALLOWS AIR INTO THE PUMP CAUSING ROUGH OPERATION AND PULSATION. REPOSITION THE STRAINER OR REDUCE FLOW.
DO NOT USE THE PRIMER TO EVACUATE AIR FROM LDH SUPPLY HOSES. NFPA SPECIFIES AIR BLEEDS FOR THIS PURPOSE. HIGH PRESSURES CAN DAMAGE THE PRIMER.
Note: Holding the primer ON for about one (1) or two (2) seconds while discharging
water after prime helps keep the primer clean of debris and promotes longer primer life.

5 System Maintenance

5.1 GENERAL MAINTENANCE

The following procedures are for normal use and conditions. Extreme condi­tions may indicate a need for increased maintenance. The procedures in this section identify measures needed to ensure lengthened pump life and continu­ing dependability. Always follow local maintenance and test procedures.
Wherever there is a requirement for new parts, it is recommended to use only Hale authorized replacement parts for optimum safety of the equipment and its operators and to limit “downtime.”
For a parts breakdown and identification, see Section 7, “Drawing Package” on page 53.
Maintenance ❑
READ ALL INSTRUCTIONS THOROUGHLY
BEFORE BEGINNING ANY SERVICE REPAIR.
Weekly
Priming System Test
1. Tighten all pump caps, and close all pump valves.
2. Pull the primer control while you watch for a below-zero (0) reading on the master intake gauge.
3. Continue operation for two (2) or three (3) seconds after the primer starts flushing water to clear any possible dirt or sludge (gum) buildup. This buildup affects primer operation by jamming vanes which reduces primer life.
4. Verify that the master intake gauge readings hold for approximately five (5) minutes after you release the primer control. A drop of up to 10” Hg. during this 5 minute period is anticipated per NFPA 1901 standards.
ESP Primer System I nstruction Guide p/n: 029-0810-01-0
5. If air leaks are heard or the gauge bounces back to or above zero (0), the pump or valves require service.
35
❑ Maintenance
Monthly
Priming System Test, Dry Vacuum Test
(Refer to NFPA 1901 or NFPA 1911)
1. Close all valves and drains. Cap all suction openings and the outlet of the suction side relief valve (if so equipped).
2. Connect a test vacuum gauge or manometer to the intake test gauge con­nection on the pump panel.
3. Engage the priming pump until the gauge indicates 22” Hg. vacuum.
For SPV, press and hold the prime push button to energize the priming pump motor; for PVG, pull the primer handle.
4. Compare the readings of the test gauge and the apparatus gauge. Note any difference.
Figure 5-1: PVG Prim-
ing Valve Handle
5. STOP the priming pump and observe the gauge.
6. If the vacuum falls more then 10” Hg. in five (5) minutes, it is an indication of at least one air leak.
Vacuum leaks may often be detected by ear if the apparatus engine is turned OFF.
Correct leaks immediately before returning the pump to service.
7. Test the suction hose as follows:
❑ Attach the suction hose to the pump.
❑ Place the suction tube cap on the end of the hose in place of a strainer.
❑ Close all valves and drains. Cap all suction openings and the outlet of the
suction side relief valve (if so equipped).
❑ Connect a test vacuum gauge or manometer to the intake test gauge con-
nection on the pump panel.
❑ Engage the priming pump until the gauge indicates at least 22” Hg.
36
❑ If the vacuum falls more then 10” in 5 minutes, at least one air leak.
❑ Verify the test gauge and the apparatus gauge display the same readings.

Troubleshooting ❑
Condition

Pump Loses Prime or Will Not Prime.

Possible
Cause
Electric priming system.
Note: Weekly priming is recommended to ensure proper operation.
Inoperative priming system or possible clogged priming pump.
Suggested Corrective Action
• To prevent possible pump damage, DO NOT EXCEED an engine speed of 1,000rpm!
• See Section 2.2 “SPV Priming Valve” on page 12. Also see “PVG Priming Valve” on page 14.
Note: Using lubricant on the vanes and vane slots during disassembly and cleaning eventually causes a gummy residue to develop, rendering the system inoperative.
DO NOT LUBRICATE VANES AND VANE SLOTS.
• Check the priming system by performing a “Dry Vacuum Test” per NFPA standards. If the pump holds vacuum, but primer pulls less than 22” Hg., it could indicate excessive wear in the primmer.
• See Section 5 Maintenance, heading “Weekly” on page 35. Also see Section 5 Maintenance, heading “Annually” on page
37.
• See Section 2.2 “SPV Priming Valve” on page 12. Also see “PVG Priming Valve” on page 14.
• Repair and/or replace accordingly.
Note: Using lubricant on the vanes and vane slots during disassembly and cleaning eventually causes a gummy residue to develop, rendering the sys­tem inoperative.
Suction lifts too high. • DO NOT attempt lifts exceeding 22’ (6.7 meters) except at low
Blocked or restricted suction strainer.

elevation.
• Remove obstruction from suction hose strainer.
• Thoroughly clean strainer screen.

Troubleshooting
Condition
Pump Loses Prime or Will Not Prime ­continued.
Possible
Cause
Suggested Corrective Action
Suction connections. • Clean and tighten all suction connections.
• Check suction hose and hose gaskets for possible defects - repair and/or replace.
Air trapped in suction line.
• Avoid placing any part of the suction hose higher than the suction intake.
• Suction hose should be laid out with continuous decline to fluid supply.
• If trap in hose in unavoidable, repeated priming may be needed to eliminate air pockets in suction hose.
Insufficient priming. • Proper priming procedures should be followed.
• Do not release the primer control before assuring a complete prime.
• Open the discharge valve slowly during completion of prime to ensure complete prime.
NOTICE !
DO NOT RUN THE PRIMER OVER FORTY-FIVE (45) SECONDS. IF PRIME IS NOT
ACHIEVED WITHIN 45 SECONDS, STOP AND LOOK FOR CAUSES
(AIR LEAKS OR BLOCKED SUCTION HOSES).
Pump pressure too low when nozzle is opened.
• Prime pump again and maintain higher pump pressure while open­ing the discharge valve slowly.
Chart continued on
next page.
Air leaks. • Attempt to located and correct air leaks using the following proce-
dures:
• Perform “Dry Vacuum Test” on pump per NFPA standards with 22” Hg. minimum vacuum required with loss not to exceed 10” Hg. in five (5) minutes.
• If a minimum of 22” Hg. cannot be achieved, the priming device or system may be inoperative, or the leak is too big for the primer to overcome (such as an open valve). The loss of vac­uum indicates leakage and could prevent priming or cause loss of prime.
• After priming shut OFF the engine. Audible detection of a leak is often possible.
• Connect the suction hose from the hydrant or the discharge of another pumper to pressurize the pump with water and look for vis­ible leakage and correct. A pressure of 100 PSI (6.9 BAR / 0.7 MPa) should be sufficient. DO NOT exceed pressure limitations of pump, accessories or piping connections.
• The suction side relief valve can leak. Plug the valve outlet con­nection and retest

Suggested Corrective Action
• Check solenoid base screws for tightness and corrosion, especially under the hold-down tangs - clean accordingly. Switch base must be properly grounded to motor and motor to chassis.
• Continuity test and check each cable for defects, i.e., fraying, splits, corrosion, etc. See electrical installation detail plate drawing on page 54. Repair and/or replace accordingly.
• Check apparatus battery for full charge - service accordingly.
• Using VOM (volt ohm meter), check wires for proper voltage ­12VDC requires minimum of 9.0VDC; 24VDC requires minimum of 18.0VDC.
• Check that hardware is tight and torqued to specifications. See mechanical installation detail plate drawing on page 54.
• Hair line cracks in the plastic body allow moisture to enter and short the internal circuity. If suspect, replace solenoid.

Switch chatters, pops or clicks, but the motor does not work.
