Introduction
2-12 Stainless Max Series Pumps
A ESP series priming pump also uses a single control to open the
priming valve between the pump and the priming pump, and start
the priming motor.
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 for Remote Mounting
(SPVR)
A hose is connected from the SPVR to the priming tap on the
Stainless Max pump body. A single push-button on the
operator’s panel starts the priming pump motor. When a
vacuum is created, the SPVR opens. (See Figure 2-13: “SPVR
Priming Valve.”) Releasing the push-button stops the priming
pump and the SPVR closes.
❑
The Hale PVG Priming Valve
The PVG is mounted on the pump operator’s panel. The PVG is
a combination valve and switch.
