2A.4 PRIMING SYSTEMS
Hale recommends and uses Rotary Vane Positive Displacement ESP
pumps for priming. Priming pumps are used to evacuate air in the suction
hose and pump. (See Figure 2a-6: “Rotary Vane ESP Priming Pump.”)
Figure 2a-6: 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 addi-
tional 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 (SPVR), for Remote Mounting
A single push button on the operator’s panel starts the priming pump
motor. When a vacuum is created, the SPVR OPENS. (See Figure 2a-
7: “SPVR Priming Valves,” on page 42.)
Releasing the push button stops the priming pump and the SPVR
CLOSES.
