Since liquefied gases boil when
drawn into a pump by its own
suction, the pump must be fed by
gravity flow to give stable,
trouble-free operation.
Never locate pump above level of liquid feeding pump.
Product must be able to flow by gravity into pump.
Positive closure of back check valve
prevents proper vapor return for pump
priming.
Always pipe bypass back to tank! Make
sure bypass line is large enough to handle
full pump flow without excessive pressure
build-up. Note that bypass line must be
capable of bypassing full pump capacity
without excessive pressure build-up. High
pressure rise can cause bypass valve to
chatter and vibrate.
