WARNING
HAZARDOUS SITUATIONS MAY OCCUR UNLESS THIS EQUIPMENT IS APPLIED, INSTALLED, OPERATED,
AND MAINTAINED BY THOROUGHLY QUALIFIED PERSONNEL IN STRICT ACCORDANCE WITH THE
INSTRUCTION MANUAL AND ALL APPLICABLE DRAWINGS AND CODES.

WARNING:
Be sure that there is nothing remaining in the pump that could react
with the liquid that will be pumped or that would have an excessive
vapor pressure at the system operating temperature. For example,
water residue left in the pump, when exposed to the operating tem-
perature of the system, would create a vapor pressure in excess of
the capability of the system to retain it, therefore causing an explo-
sion that could prove fatal.
4) R plac th casing drain plug and th s al v nt plug.
5) R mov th “storag ” prot ctiv coating from th xt rnal sur-
fac s of th pump.
Pumps must also b prot ct d from moistur , dirt, and physical dam-
ag , during and aft r installation whil th syst m is b ing compl t-
d. Pumps “stor d” on th ir foundations must b compl t ly ch ck d
for prop r installation prior to start-up.

SUCTION AND DISCHARGE PIPING
Suction and discharg nozzl siz s of D an pumps ar s l ct d for
prop r p rformanc of th pumping unit and ar not int nd d to
d t rmin th suction and discharg pip siz s. Pip siz s must b
d t rmin d by th us r bas d on th syst m r quir m nts.
Suction piping should hav a minimum friction loss and thus should
b as short and straight as possibl with a pip diam t r as larg
as conomically f asibl for th flow rat handl d.
Suction piping should n v r b small r in diam t r than th suction
nozzl siz . Wh n th suction piping is larg r than th suction noz-
zl siz an cc ntric r duc r is r quir d at th suction flang and
must b install d with th tap r locat d on th und rsid to limi-
nat air or vapor pock ts. Th s ction of piping attach d to th suc-
tion flang of th pump should b straight for a l ngth of ight pip
diam t rs or mor .
Discharg piping may b th sam siz as, larg r, or small r than
th discharg nozzl as th syst m flow may d mand.
In n w installations or r built syst ms, dirt, pip scal , w lding slag,

vibra tion, short bearing life, and reduced mechanical seal life.
Pumps ar not construct d to b us d as pip anchors. Both suction
and discharg piping must b support d ind p nd ntly of th
pumping unit and th rmal xpansion joints provid d to guard
against xpansion loads on th pump. Pip s should b anchor d
b tw n th xpansion joint and th pump and as clos ly to th
pump as possibl . Failur to provid prop r piping support and
xpansion joints may impos strains on th pump ing unit which will
r sult in s rious misalignm nt. Maximum allowabl piping loads
ar shown on pag 6 in this manual.
No allowanc for th rmal xpansion is mad for motor driv n units
in mounting th driv r. Allowanc for turbin mounting should b in
accordanc with th turbin manufactur r’s r comm ndations.
Final alignment must always be checked and corrected at the
operating temperatures of the pump and driver.
Misalignm nt of th two shafts is of two kinds. Th first of th s is
angular misalignm nt wh r th axis of on shaft is at an angl
from th oth r. Th oth r is offs t alignm nt wh r th c nt r of on
shaft is offs t from th c nt r of th oth r shaft. Th s ff cts usual-
ly occur tog th r so that both angular and offs t misalignm nt ar
pr s nt.
Coincid nt alignm nt of th driv r and pump shaft is m asur d at
th fac s of th coupling hubs. B caus of th vari ty of coupling
typ s furnish d at custom r’s r qu st, th proc dur h r giv n is
g n ral in natur but may b appli d by simpl adaption to most
coupling typ s.
Th pump was shipp d with th coupling spac r not install d, to
allow alignm nt and motor rotation ch ck. If, how v r, som on

RA2096 pumps ar shipp d with on of th coupling spac r
flang s bolt d to th pump hub to s cur th cooling fan (It m
#120) for shipping. Loos n th four bolts that ar s curing this
flang and r mov it.
To on of th coupling hubs, ith r on th motor shaft or th pump

indicator button rid s on th fac of th oth r coupling hub n ar th
outsid diam t r of th hub. R f r nc th illustration “INDICATOR

Angular and offs t alignm nt is adjust d by moving th motor sid -
ways and up and down to bring th motor into xact alignm nt
with th bolt d down pump. Th motor is mov d up and down by
adding and r moving thin m tal shims b tw n th motor f t and
th bas plat . If misalignment is of ma or proportions, the base-
plate has been improperly installed on the foundation and must be
releveled before proceeding with alignment.

The closer the running alignment, the longer the running life will be.

Th “RA” pumps ar arrang d with a m chanical fac s al (95A
and 95B) that was sp cifically s l ct d for s aling th mor
commonly us d h at transf r oils. Som of th h at transf r oils
“oxidiz ”. Th manufactur r of any h at transf r oil that oxidiz s
will r comm nd that a nitrog n gas blank t b maintain d on
th xpansion tank of th syst m to assur that oxyg n cannot
com in contact with th oil. Th “RA” pumps hav a cavity pro-
vid d b tw n th m chanical s al stationary (95A) and th
front gr as s al (76) to allow th us of a barri r fluid to k p
oxyg n away from th m chanical s al fac s wh n op rating
with an oxidizing oil.
All “oils” will oxidiz at som point d p nding upon th amount of
air contamination and th t mp ratur . Most “oils” will b gin to
oxidiz at 250°F. Som “oils” will oxidiz as low as 150°F. Th oxi-
dation rat doubl s for v ry 18 to 20°F incr as in t mp ratur ,
so it is v ry important to not us a barri r fluid that has a low oxi-
dation t mp ratur . Th us r should ch ck to s at what t mp ra-
tur his oil will start to oxidiz .
Wh n th oil b ing pump d is on that oxidiz s, a barri r fluid
should b us d. S l ct a fluid to b us d as th barri r fluid that is
compatibl with th pumpag and not d trim ntal to th lip s al,
b arings, m chanical s al, or th b aring housing. Th b st fluid to
us is nitrog n, but many custom rs pr f r to us a liquid inst ad
of a gas. Many oil compani s produc a (barri r) oil that would b
compatibl with th oil b ing pump d, m chanical s al lastom rs,
lip s al, b arings, b aring gr as , and th b aring housing. Two
xampl s of this typ of oil ar Calflo AF (P tro-Canada) and
Dowth rm RP (Dow Ch mical). Th us r should ch ck with his oil
suppli r for his r comm ndation for a non-oxidizing or low oxidiz-

Sinc most of our custom rs ar using a liquid as a barri r fluid, th
pump is suppli d with th barri r oil piping shown at th bottom of

It is important that a pump should n v r b subj ct d to th rmal or
pr ssur shock. Th liquid should th r for b allow d to flow into
th casing slowly. A c ntrifugal pump should n v r b start d until
all th parts ar up to th t mp ratur of th liquid to b pump d.
FILLING
WARNING:
Before filling the pump with liquid, check to see that all possible
leak locations are sealed. See that all of the connections into the
pressure containing cavity are sealed or connected to a related
piping system that also has all possible leak paths sealed. Do not
plug unused cavities, as this could develop dangerous pressure
build-up. Use a wrench on all bolted oints to apply torque to assure
that all gaskets are sealed in a tight oint. Check to see that all
threaded pipe connections are also tight enough to seal the Liquid
pressure that will be applied when the system is started.
WARNING:
Filling directions below refer to venting of “air” to the atmosphere,
but dependent upon the physical properties of the liquid intended
to be pumped, temperature, pressure, and other variables related
to the system and its operational requirements, this may not be
allowed by federal or local regulations, or may not be acceptable
for whatever other reasons. Consult your plant or corporate safety
engineer for instruction on possible required procedures for the
specific liquid, operating conditions and legal requirements.
Wh n th sourc of th liquid to b pump d is b low atmosph ric
pr ssur or locat d b low th pump, th filling may b ac -
complish d in any of s v ral ways, thr of which ar list d b low:
1) An xhaust r may b conn ct d to th discharg piping
b tw n th pump and th discharg isolation valv . With th
discharg isolation valv clos d and th suction valv op n,
th air can b xhaust d from th pump and th suction pip-
ing. Wh n all th air has b n r mov d, clos th suction
valv , r mov th xhaust r, plug th acc ss port wh r th
xhaust r was conn ct d, and th n op n th discharg valv .
R mov th s al v nt plug from th top of th b aring housing,
r f r to th drawings on pag 6. Allow th air to flow from this
port until th pumpag starts to flow. This could tak consid r-
abl tim d p nd nt upon th viscosity of th pumpag .
Fift n to tw nty minut s is not unusual, how v r som liquids
may v nt out in l ss than a minut . If th pump is a “RA2096”
us a funn l and fill th s al cavity, through this conn ction
with cl an pumpag .
2) With a foot valv install d in th suction piping, th pump may
b fill d with pumpag introduc d som wh r abov th
pump in th discharg piping. A foot valv may cr at xt n-
siv loss s and th r for must b allow d for in calculating th
availabl NPSH. Wh n th pump is fill d, plug th port
through which you w r filling. R mov th s al v nt plug from
th top of th b aring housing, r f r to th drawings on pag
6. Allow th air to flow from this port until th pumpag starts
to flow. This could tak consid rabl tim d p nd nt upon th
viscosity of th pumpag . Fift n to tw nty minut s is not
unusual, how v r som liquids may v nt out in l ss than a
minut . If th pump is a “RA2096”, us a funn l and fill th
s al cavity, through this conn ction with cl an pumpag .
3) A vacuum pump (pr f rably a w t vacuum pump) may b
us d for vacuating air from th pump and piping. Th vacu-
um pump should b conn ct d as is th xhaust r cov r d in
No. 1 abov and th proc dur is th sam .
Wh n th sourc of th liquid to b pump d is abov atmosph ric
pr ssur or abov th pumps discharg flang , th pump may b
fill d by v nting through a bl d-off lin to atmosph r . Wh n th
sourc of th liquid is abov th pumps discharg flang th v nt-
ing could b back to th suction sourc , inst ad of to atmosph r .
Wh n all of th air has b n xp ll d through th bl d-off, s al it.
R mov th s al v nt plug from th top of th b aring housing, r f r
to th drawings on pag 6. Allow th air to flow from this conn c-
tion until th pumpag starts to flow. This could tak a consid rabl
amount of tim , d p nd nt upon th viscosity of th pumpag .
Fift n to tw nty minut s is not unusual, how v r som liquids may
v nt out in l ss than a minut . If th pump is a “RA2096”, us a fun-
n l to fill s al cavity, through this conn ction with cl an pumpag .
It is most important to check the direction of rotation of the pump
before allowing the pump to come up to speed. Th pump was
shipp d with th coupling spac r not install d to allow alignm nt
and motor rotation dir ction ch ck. If, how v r, som on install d
this spac r ass mbly, r mov it at this tim . To ch ck rotation dir c-
tion, push th starting button and instantly push th stop button. This
will allow th motor to turn ov r a f w r volutions and th dir ction
of rotation to b obs rv d. A dir ction of rotation arrow is shown
on th front of th pump casing. If rotation is incorr ct, chang th
wiring conn ctions and r ch ck rotation. Operating the pump in
reverse rotation may cause extensive damage.
WARNING:
Lock-out the power to the driver (motor, turbine, engine, etc.) install
the shaft coupling spacer. Be sure that you install all the retaining
devices and bolts and that they are tight. Read and comply with the
coupling manufacturer’s instructions. Personal in ury, death, and/or
equipment damage could occur if the coupling spacer is not prop-
erly installed. Remove all debris and tools from the area near the
shafts and the shaft coupling. Do this to assure that nothing is
caught and thrown by the rotating parts when the pump is started.
Bolt the coupling guard securely to the baseplate, checking to
assure that it is not contacting any parts that will rotate when the
pump is started.
OPERATING
WARNING:
Before starting the unit, see that all personnel are a safe distance
away from all possible hazards, that all sub-systems are connected
and operating, that all debris has been removed, that the shaft cou-
pling guard is securely in place, and that the pump is full of
liquid.
Do not operate this pump at shut-off (no flow) as an explosion may
result. This can occur with any liquid, even “cold water”. Personal
in ury, death, equipment damage, and/or loss of product
(pumpage) is Likely to occur. If your system is operated where it is
possible for all outlets of the discharge from the pump to be closed
while the pump is still operating, a modification of the system needs
to be made to assure a continual flow of pumpage through the
pump. NOTE: Some people have a belief that a bypass line from the
discharge side of the pump to the suction side of the pump will
relieve this problem, this is “NOT TRUE”; DO NOT ATTEMPT THIS.
WARNING:
Do not operate a pump at a low flow condition, unless provision has
been made to prevent dangerous heat build up within the pump
casing. The liquid in the pump will heat up and this may result in
high pressure in the pump in a short time. Such pressure may result
in a rupture of the pressure-containing parts and cause severe haz-
ard to personnel and/or damage to the system.
