Accessories

section. With 200 liter (55

gallon) drum length pumps, screw the bung adapter

(B) tightly into the bung hole of the drum and adjust to

hold the pump 13 mm (0.5 in.) of

f the bottom of the

drum. Loosen the vent plug (A) to prevent formation of

a vacuum in the drum. Stubby pumps may be mounted

on a wall or on the side of a drum with a clamp. Drum

pumps can also be mounted to the side of a drum.

NOTE:

Refer to

Dimensions

on page 38 for pump

dimensions, and air inlet and fluid outlet sizes.

If low level cut-off valve 210–865 is being used, install

a drum length pump (except Model 226–951) in the

container with the valve 210–865 resting on the con

tainer bottom. This accessory valve will not fit pumps

with a telescoping suction tube, such as Model

226–951.

CAUTION

If low level cut-of

f valve 210–865 is used, install it

with a strap wrench to avoid damaging the valve.

Do not use the legs of the valve to tighten it into

the pump.

Installation

System Accessories

Refer

to Fig. 2 and the Accessories section.

NOTE: T

o ensure maximum pump performance, be

sure that all accessories used are properly sized to

meet your system’

s requirements.

Most models are supplied with a needle-type air con

trol valve (K) at the pump air inlet. Model 226–951 is

equipped with an air regulator kit (CC) instead (see

Fig. 3). All models are supplied with an air line quick

disconnect coupler (L) to connect the air line to the

pump and accessories.

A bleed-type master air valve (D) and a fluid drain

valve

(G) are required in your system, to help re

duce the risk of serious injury

, including splashing

fluid in the eyes or on the skin, and injury from

moving parts if you are adjusting or repairing the

pump.

The

bleed-type master air valve

(D) relieves air

trapped between this valve and the pump after the

pump is shut of

f. T

rapped air can cause the pump

to cycle unexpectedly and result in serious injury

including amputation. Locate the valve close to the

pump.

The

fluid drain valve

(G) helps relieve pressure in

the displacement pump, hose, and dispensing

valve when shutting of

f the pump. Actuating the

dispensing valve to relieve pressure may not be

suf

ficient, especially if there is a clog in the hose or

the dispensing valve.

WARNING

For automatic air motor lubrication, install an air line

lubricator (C) downstream from the air regulator (if

supplied) and all other accessories. Install a bleed-type

master air valve (D) close to the pump. Next, install the

air regulator (CC), if supplied. Install an air line filter (E)

upstream from all other accessories, to remove harm

ful dirt and moisture from the compressed air supply

Using a suitable adapter

, install the male disconnect

pin fitting (J) in the air filter inlet. Install the air line

quick disconnect coupler (L) on the air hose (F), but do

not connect it to the pin fitting yet.

Connect an electrically conductive fluid hose (M) to the

3/4 npt(f) fluid outlet.

Model 226–951 Only

Using

moderate force, extend the pump suction tube,

insert the pump into the drum or tank bung hole, and

screw the bung adapter (B) tightly into the bung hole.

Lift the pump about 13 mm (0.5 in.) and tighten the

bung adapter (B) screw to hold the pump. Loosen the

vent plug (A). Refer to Fig. 2.

CAUTION

o prevent damaging the o-ring seals inside the

suction tube, do not use excessive force when ex

tending the suction tube.

Operation

Pressure Relief Procedure

PRESSURIZED

EQUIPMENT HAZARD

The equipment stays pressurized until pressure is

manually relieved. To reduce the risk of serious

injury from pressurized fluid, accidental spray from

the gun or splashing fluid, follow this procedure

whenever you:



Are instructed to relieve pressure,



Have an air supply interruption,



Stop pumping,



Check, clean or service any system equipment,



Install or clean fluid nozzles.

WARNING

Shut of

f the air to the pump.

Close the bleed-type master air valve (required in

your system).

Hold a metal part of the dispensing valve firmly to

the side of a grounded metal pail, and trigger the

valve to relieve pressure.

Open the fluid drain valve (required in your sys

tem) to relieve all fluid pressure, having a contain

er ready to catch the drainage.

Leave the drain valve open until you are ready to

dispense again.

If you suspect that the nozzle or hose is completely

clogged, or that pressure has not been fully relieved

after following the steps above,

very slowly

loosen the

hose end coupling and relieve pressure gradually

, then

loosen completely

. Now clear the nozzle or hose.

Flush the Pump Before Using

The

pump was tested in lightweight oil, which was left

in to protect pump parts. T

o prevent contamination of

the fluid you are pumping, flush the pump with a com

patible solvent before using it.

o flush the pump, connect a short hose to the pump

outlet, insert the pump intake into a pail of compatible

solvent, direct the hose into a pail, and start the pump

as explained at right.

Cycle the pump slowly for at least 5 minutes, then stop

and disconnect the air hose. Push up on the ball of the

intake valve (N) to drain the lower part of the pump.

See Fig. 4. T

urn the pump over to drain the upper part

of the pump.

03765

Fig. 4

Starting and Adjusting the Pump

With

the air valve (K) or regulator (CC) closed, turn on

the air supply and connect the air line coupler (L). See

Figs. 3 or 5. Make sure all dispensing valves are open.

Slowly open the air valve (K) or regulator (CC) until the

pump cycles 5 to 20 cycles per minute. The pump it

self only takes a few strokes to prime. In a large sys

tem, however

, the pump may have to be cycled for

several minutes to fill all the lines. Once the entire sys

tem is primed, use the air valve or regulator to control

pump speed and cycle rate; always use the lowest

pressure necessary to get the desired results.

When used for transfer and supply operations with no

dispensing valve, the pump will run whenever air is

supplied.

Pump Shutdown

WARNING

reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure

at left.

Disconnect the air line coupler (L).

Relieve the pressure.

 

Maintenance

Fill the wet-cup (P) 1/2 full of Graco Throat Seal Liquid

(TSL) or compatible solvent and keep it 1/2 full to keep

fluid from drying on the displacement rod and damag

ing pump throat packings. See Fig. 5.

Lubricate the throat packings frequently when you are

pumping a non-lubricating fluid, or are shutting down

for more than a few days. Some pumps have a grease

fitting (DD) for this purpose. See Fig. 5.

The accessory air line lubricator (C) provides automat

ic air motor lubrication. T

o manually lubricate the mo

tor

, disconnect the air line at the air motor inlet, put

about 15 drops of lightweight oil in the inlet, reconnect

the air line and turn on the air to blow oil into the motor

Never allow the pump to run dry of fluid being pumped.

A dry pump will quickly accelerate to a high speed,

possibly damaging itself. If your pump accelerates

quickly

, or is running too fast, stop it immediately and

check the fluid supply

. If the supply container is empty

and air has been pumped into the lines, prime the

pump and lines with fluid, or flush and leave filled with

compatible solvent. Be sure to eliminate all air from the

fluid system.

WARNING

o reduce the risk of serious injury whenever you

are instructed to relieve pressure, always follow the

Pressure Relief Procedure

on page 8.

Do not attempt to adjust the packing nut with the

pump operating.

WARNING

Periodically

, check the tightness of the packing nut (P).

Relieve the pressure, then tighten enough to prevent

leakage; no tighter

. See Fig. 5. If the leakage can not

be stopped, change the packings to prevent exposure

to the fluid being pumped.
