1Each country may use a different form of wire size measurement (AWG, SWG, mm2 etc.). The above wiring size chart is based on the United States
National Electrical Code (NEC) guidelines for America Wire Gauge (AWG) sizes. These wire sizes and distances are based on nominal supplied voltages.
Additional derating is necessary when the voltage is less than that shown. Consult your local standards and regulation for specific wiring requirements.

Do not use restricted inlet line! Use inlet line larger than
pump suction nozzle. Same
size nozzle OK on short runs.
Concentric Reducer Eccentric Reducer
Do not allow bypass line to
have low spot.
Keep return line level
or go up toward tank!
Pressure drop caused by restriction in suction line will cause vaporization and cavitation.
An eccentric reducer should always be used when reducing into any pump inlet where vapor might be
encountered in the pumpage. The at upper portion of the reducer prevents an accumulation of vapor that
could interfere with pumping action.
Low spots in bypass line can collect liquid which prevents normal vapor passage for priming purposes just like the
P trap in the drain of a kitchen sink. This is not a problem for bypass lines where vapor elimination is not required.

Always locate pump below tank
level ...the lower the better!
Never locate pump above
level of liquid feeding pump.
Product must be able to ow
by gravity into pump.
Back Check Valve
Positive closure of back
check valve prevents propervapor return for pump priming.
Do not pipebypass lineback intosuction piping!Heat building inrecirculated productscauses ashing of
liquid to vapor with immediate cavitation andultimate dry-running. This is why the bypassrelief valves which are built into many positivedisplacement pumps should not be used fornormal bypass action when handling liqueed gases. The internalvalve should be considered to be a back-up safety relief inaddition to a back-to-tank bypass valve and should be set torelieve at a pressure 10 to 20 psi higher than the working bypass.Some built-in bypass valves have the capability of being pipedback-to-tank so check with the pump manufacturer.
Always pipe
bypass back
to tank! Make
sure bypass
line is large
enough to handle
full pump ow
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.
Since liqueed gases boil when drawn into a pump by its own suction, the pump must be fed by gravity o
to give stable, trouble-free operation.

and B is

bypass and vaporelimination valve.
Valve A is a xed pressure bypass like the Fisher 98H which limits
the feed pressure into the vaporizer to a specic value regardless of
system vapor pressure. A differential bypass valve like the Corken
B166, T166, or B177 controls a xed difference in pressure between
the pump discharge and the tank. Differential valve B must be set to
the maximum acceptable differential of the pump while xed
pressure valve A is set for the vaporizer pressure requirement.
