Introduction ❑
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.”)
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 opera-
tion. 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 “Lubri-
cated 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.

❑Introduction

p/n: 029-0810-01-0
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.”)
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.

13
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 prim-
ing 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 configura-
tions. 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.

❑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 oper-
ating conditions (standard climates) our research has found that no lubri-
cant is required.

15
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 Lubri-
cated System.”)
Propylene Glycol is a less toxic and more environmentally-friendly coolant
and is recommended over Ethylene Glycol based antifreeze.Propylene Gly-
col (PG) based antifreeze provides comparable system protection to that of
conventional ethylene glycol (EG) based coolants (i.e., freeze, and corro-
sion 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.
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
