3.4 PRIMING SYSTEMS
Hale uses Rotary Vane Positive Displacement ESP pumps for priming. Priming
pumps are used to evacuate air in the suction hose and pump.
Figure 3-5: 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. See separate manual, Hale p/n:
029-0810-01-0, for additional installation and operating instructions.
Priming Valves
Hale priming valves open when the priming pump is operated to allow the air to
escape from the pump. Two priming valves are offered:
 Hale Semi-Automatic Priming Valve (SPV)
A single push button on the operator’s panel starts the priming pump motor. When
a vacuum is created, the SPV OPENS. (See Figure 3-6: “SPVR Priming Valve
(Shown),” on page 42.)
Releasing the push button stops the priming pump and the SPV CLOSES.
