PLACING PUMP IN SERVICE
LUBRICATION
Ingersoll–Rand No. 50 Ingersoll–Rand No. 80
Always use an air line lubricator with this pump.
We recommend the following Filter–Lubricator–Regulator
Unit:
For USA – No. 8LUB12
For International – No. 8LUB12
Before starting the pump, fill the oil chamber in the
Backhead (1) with Ingersoll–Rand No. 50 Oil and inject
about 3 cc of oil into the air inlet before attaching the air
hose.
Before starting the pump and after four hours of
operation, unless the air line lubricator is used, detach the
air hose and fill the oil chamber in the Backhead (1) with
Ingersoll–Rand No. 50 Oil.
After each forty hours of operation, or as experience
indicates, inject 5 – 10 cc of the Ingersoll–Rand No. 80
Grease into the Grease Fitting (15).
Never use ordinary cup grease as it emulsifies with water
and will not lubricate in this condition. Automotive water
pump grease is not satisfactory as it is made for use with
hot water. AIR STRAINER
Periodically, clean the Air Strainer Screen (9) as follows:
1. Shut off the air supply to the pump.
2. Unscrew the Air Strainer Plug (11).
3. If the Screen still appears clogged, unscrew the Air
Strainer Cap (10) and withdraw the Screen. Clean the
Screen in a suitable cleaning solution.
IMPELLER ADJUSTMENT
For the most efficient operation of the pump, particularly
against high heads, it is necessary that the clearance
between the Impeller (42) and the Impeller Cover (46) be
limited. This clearance is set at 0.010” at the factory.
When, due to wear, this clearance has increased to about
1/32”, an adjustment can be made by removing enough of
the Impeller Cover Shims (45) to obtain the original 0.010”
clearance. This simple adjustment will prolong the life of
the Impeller and maintain the high efficiency of the pump.
The Impeller Cover Shims are different colors to identify
the various thicknesses.

     
Impeller Shims (41) are used as required between the
Impeller and the Impeller Spacer (40) to provide running
clearance between the Impeller and the Housing (14).
When assembling a pump, install only enough Impeller
Shims to permit the Impeller to rotate without any drag.
OILER ADJUSTMENT
The Oiler is adjusted at the factory, but since flow rate
varies somewhat with temperature, readjustment may be
necessary. The rate of flow is regulated by an Oiler
Adjusting Screw.
To regulate the Oiler:
Remove the Backhead and turn the Oiler Adjusting Screw.
Turning the Screw clockwise decreases the flow; turning
the Screw counterclockwise increases the flow. Under no
circumstances should the Screw be backed out beyond the
face of the Backhead.

PLACING PUMP IN SERVICE
OPERATION
Always use an Exhaust Hose and be certain the free end of
the Hose is kept well above the surface of the liquid.
Do not allow the pump to operate at free speed (not
submerged) for long periods of time. The frictional heat
generated will damage the composition sealing members.
Prevent dirt from entering the pump. When pumping from a
ditch or natural sump, set the pump on a board or flat stone
or suspend it a few inches from the bottom of the sump.
Arranging a wire screen around the inlet or setting the
pump in a wire basket is also recommended.
If the inlet becomes clogged, stop the motor and lift the
pump from the liquid. Liquid flowing through the
discharge line will usually flush the obstruction from the
inlet.
If the pump is stopped while pumping dirty liquids, gravel
washed back through the pump by the liquid in the
discharge line may sprag the impeller and prevent the
motor from starting when the air is turned on. If the gravel
cannot be dislodged by jarring or striking the pump with a
wooden block; make sure that the air is turned off, remove
the air line from the pump, remove the Inlet and rotate the
Impeller by hand.
INSTALLATION
Air Supply and Connections
Always use clean dry air at 90 psig maximum air pressure.
Dust, corrosive fumes and/or excessive moisture can ruin
the motor of an air tool. An air line filter can greatly
increase the life of an air tool. The filter removes dust and
moisture. Be sure all hoses and fittings are the correct size
and are tightly secured. See Dwg. TPD905–1 for a typical
piping arrangement.

MISE EN SERVICE DES POMPES
FONCTIONNEMENT
Utiliser toujours un flexible d’échappement et s’assurer que
son extrémité libre est maintenue au–dessus de la surface
du liquide.
Ne pas laisser tourner la pompe à sa vitesse à vide (non
submergée) pendant de longues périodes. La chaleur causée
par le frottement endommagera les organes des joints
composés.
Eviter l’entrée des saletés dans la pompe. Pour le pompage
dans un caniveau ou dans un puisard naturel, poser la
pompe sur une planche ou une pierre plate, ou la suspendre
à quelques centimètres du fond du puisard. La mise en
place d’un grillage de protection autour de l’admission ou
l’installation de la pompe dans un panier est également
recommandée.
Si l’admission se colmate, arrêter le moteur et sortir la
pompe du liquide. Le liquide s’écoulant par le refoulement
dégagera généralement l’obstruction de l’admission.
Si la pompe est arrêtée pendant le pompage de liquides
sales, les graviers entraînés dans la pompe par le retour du
liquide pourront bloquer l’impulseur et empêcher la
rotation du moteur lorsque l’alimentation d’air comprimé
est remise en service. Si les graviers ne peuvent pas être
déplacés en secouant ou en frappant la pompe avec un bloc
en bois s’assurer que l’alimentation d’air est bien mise hors
service, déconnecter le flexible d’alimentation, déposer le
raccord d’admission et tourner l’impulseur à la main.
S’assurer que la soupape de régulation coulisse librement
dans son fourreau. Une soupape de régulation grippée est la
cause la plus courante d’une vitesse irrégulière du moteur.
Un ajustement libre causé par une soupape très usée produit
le même effet.

FUNCIONAMIENTO
Use siempre una Manguera de Escape y asegúrese que el
extremo abierto de Manguera esté arriba de la superficie del
líquido.
No permita que la bomba marche a velocidad libre (sin
sumergir) por largos períodos de tiempo. El calor de
fricción generado dañará la composición de los elementos
de junta.
Evite la entrada de suciedad en la bomba. Cuando bombee
de una fosa o depósito natural, coloque la bomba sobre una
tabla o piedra plana o suspéndala a unas pulgadas. Se
recomienda también una malla metálica alrededor de la
admisión o poner la bomba en una cesta de alambre.
Si se atasca la admisión, pare el motor y saque la bomba del
líquido. El flujo de líquido a través de la línea de descarga
normalmente limpiará la obstrucción de admisión.
Si se para la bomba cuando está bombeando líquido sucio,
puede ser que el impulsor haya quedado atascado por
arenilla retrocedida de la línea de descarga, evitando el
arranque de motor cuando el aire esta conectado. Si las
arenillas no salen agitando o golpeando la bomba con un
bloque de madera; asegúrese que el aire esté desconectado,
saque la línea de aire comprimido de bomba, saque la

OPERAÇÃO
Use sempre uma Mangueira de Exaustão e esteja certo de
que a extremidade livre da Mangueira é mantida bem acima
da superfície do líquido.
Não permita que esta bomba funcione com velocidade livre
(não submersa) por períodos de tempos prolongados. O
calor de fricção gerado danificará os membros da
composição selante.
Evite que sujidade entre na bomba. Quando bombear de um
furo ou açude, ajuste a Bomba numa plataforma ou rocha
ou suspenda–a alguns centímetros acima do fundo do furo.
Também se recomenda a colocação de uma tela de arame
em redor da entrada ou a montagem da bomba num cesto
de arame.
Se a Entrada ficar entupida, desligue o motor e desligue a
mangueira de alimentação de ar e erga a Bomba da água. A
passagem de água da parte traseira através da mangueira de
descarga irá expelir naturalmente a sujidade da Entrada.
Se a bomba é desligada enquanto bombeando líquidos
sujos, detritos que passem pela linha de descarga podem
travar o impulsor e impedir que o motor funcione quando o
ar for ligado. Se o cascalho não puder ser desalojado por
vibração ou golpeando a bomba com um bloco de madeira,
certifique–se de que o ar está desligado, remova a linha de
ar da bomba, e a Entrada, e gire o Impulsor com a mão.
Esteja certo de que a Válvula Mestra desliza livremente no
Rolamento. Uma Válvula Mestra pegajosa é a causa mais
comum de uma velocidade de motor desafinado. Um ajuste
frouxo ou mal feito resultante de uma Válvula ou
Rolamento muito desgastados produz o mesmo efeito.
