DESCRIPTION:
Model 2710 consists of a pump hoist for use with 400# refinery
container drums, 400# follower, Powermaster III pump tube,
air motor, and the necessary hoses and fittings to perform a
basic installation. (See Illustration 1.)
Model 2740 consists of a pump hoist for use with 400# refinery
container drums, 400# follower, Series 40 pump, and the nec-
essary hoses and fittings to perform a basic installation. (See
Illustration 2.)
Model 274680 is a basic pump hoist assembly, less pump,
for use with Powermaster III pump tubes and air motors. The
400# follower, hoses and necessary fittings are included.
Model 274681 is a basic pump hoist assembly, less pump,
for use with Series 40 pumps. The 400# follower, hoses and
necessary fittings are included.
All models are designed to hold a pump and follower in posi-
tion for insertion into a standard 400# refinery container. The
priming action of this unit is created by gravity and the vacuum
created when material is removed from the drum by the pump.
No force by the hoist is used to cause a priming action to the
pump. The follower will remain on top of the lubricant until
the container is emptied by the pump. The action of gravity
and atmospheric pressure acting on the follower will cause
the priming action, directing material into the inlet of the pump
tube.

INSTALLATION:
1. Select a location where there is adequate clearance around
the hoist to operate and maneuver around the hoist and
pump assembly when installing and removing drums.
2. The mounting base must be securely fastened to the floor
before use. Mounting dimensions are provided on Base
Mounting Dimensions illustration (See Illustration 3), or the
base may be used as a template for drilling and positioning
anchors.
3. After hoist has been secured to the floor adjust the pump
support, item 56, so that it is parallel to the floor. This will
keep the pump tube parallel with the support tube.
4. Mount pump to pump mount (item 29 or 53) depending on
model.
When attaching the Series 40 pumps to the mount, (item
53), attach pump outlet body to pump mount with four ¼-20
x 9/16 hex screw and washer assemblies, item 54. See
Series 40 Assembly Details.
When attaching the Power Master Pump to the mount,
item 29, use four extension adapters, item 40. See Power
Master III Assembly Details. Note that the extension adapt-
ers are threaded onto the pump tie rods against the tie rod
nuts, as shown in the illustration.
5. Place pump and mount into pump support, item 56, and
loosely install hex bolts, lock washers, and flat washers,
items 4, 5, &6, through slots in support. Leave loose until
final adjustment is made.
6. Assemble air inlet fittings as shown in the appropriate as-
sembly detail page for the model that is being assembled.
Assemble the air regulator, item 44, to the air inlet of the
hoist as shown in the illustration. Note that there is a 1/8
pipe plug packaged with each regulator for plugging the
unused gage port in the regulator.
7. After all fittings are assembled and tight measure and cut
a length of ¼ OD black polyurethane tubing, supplied, to
connect the air inlet to the regulator inlet as shown in the il-
lustrations. The tubing will simply push fit into the ¼ fittings
included with the model.
8. Assemble the air hose to the air coupler as required for the
model assembled. (Note that the air coupler for the Power
Master Air Motor is supplied with the air motor.) Make sure
the ball valve, item 35 or 45, is closed and the hoist control
valve, item 10, should be placed in the down position, and
attach air hose to source of filtered, regulated air. The air
pressure should be set initially to about 40 PSI.
9. Adjust the hoist air regulator, item 44, for a pressure of
around 30-40 PSI. Check for air leaks in all connections.
Slowly move the hoist control valve, item 10, to the raised
position and raise pump so the end of the pump tube will
clear the primer assembly.
Failure to securely fasten the base to the floor may result
in severe injury and or property damage. Pump hoist may
topple over if not securely fastened.
10. Attach the primer assembly to the end of the pump tube.
When assembling the Power Master Pump tube to the fol-
lower, apply some grease to the end of the pump tube, and
the O-rings inside the follower assembly. Lower the end
of the pump tube into the follower until the pump tube is
flush with the bottom of the follower. Tighten the three hex
screws, item 24, on the follower until tight.
When assembling the Series 40 pump to the follower, a
reducing adapter is used, item 55. Apply some grease to
the outside of the adapter and the O-rings on the inside
of the adapter and the inside of the follower. Push the
adapter into the follower assembly until it seats against the
shoulder. Tighten the three hex bolts on the follower, item
24, securely. Apply some grease to the end of the pump
tube and slide into the reducing adapter, item 55, until the
pump tube is flush with the bottom of the follower. Tighten
the three set screws, item 32, securely.
11. Raise the follower high enough to clear an open 400# con-
tainer. Place the container under the follower and slide the
drum back on the mounting base, item 8, until it is against
the two gusset plates on the base. Adjust the position of
the pump with respect to the drum by sliding the pump
mount (item 29 or 53) in the pump support, item 56, until
the follower is centered over the open drum. Tighten the
hex bolts, item 4, through the slots in the pump support to
secure the pump mount.
12. Using the remaining polyurethane tubing, attach to the
open fitting on the 2-way air valve, item17, mounted on the
pump support, item56, by pushing one end of the tube into
the fitting until secure. Thread the tubing down along the
pump tube to the fitting, item 1, in the top of the follower as-
sembly. Secure the tubing to the pump tube with two nylon
wire ties, supplied with the assembly.
13. Check for proper air flow by pressing button on 2-way air
valve, item17, making sure that air flows through check
valve, item 30, and out under follower assembly.
14. Connect fluid hoses to pump outlet.
Power Master Pumps are supplied with a 3/8” ID high
pressure hose with ½ NPT female threaded connections.
Thread a ¾ NPT x ½ NPT bushing adapter, item 36, into
the pump outlet and tighten securely. Thread a ½ NPT hex
nipple, item 34, into the bushing and tighten securely. At-
tach the high pressure hose, item 50, to the hex nipple and
tighten for leak free fit.
Series 40 pumps are supplied with a ¼” ID high pressure
hose, item 52, with 33/64 female thread on both ends. Two
male adapters, item 48, are supplied to adapt the hose to
¼ NPT male for the pump outlet, and working end of the
hose. Insert the hose adapters, item 48, into each end of
the high pressure hose and tighten securely for leak proof
seal. Thread one end of the hose into the pump outlet and
tighten securely. Attach the other end as required for the
application.

OPERATING CONTROLS (See Illustrations 3, 5 & 6)
Hoist Control Valve (item 10): Three position air valve used
to raise and lower the pump into and out of the drum. When
the handle is moved up, the hoist will raise. When placed in
the neutral position, with handle level with floor, hoist will stop
and hold position. When the handle is placed in down position,
the hoist will lower the pump into the drum.
Air Assist Push Button (item 17): Two way air valve used
to force air under the follower assembly to assist in lifting the
pump and follower from the drum. Used in conjunction with the
Hoist Control Valve when removing the pump and follower from
the drum.
Air Vent (item 21): Used to vent air trapped under the follower
plate when the follower and pump is lowered into the drum.
This valve should be open when the pump and follower are
lowered into the drum. Air will escape from the valve as the
follower is lowered into the drum. After the follower rests on
top of the lubricant, the valve is closed by turning clockwise to
seal the ball against the seat.
Hoist Regulator (item 44): Used to control the air pressure to
the hoist only. The air pressure should be set to the necessary
pressure required to raise the pump and follower. Too much
pressure will cause the hoist to rise very quickly and may dam-
age the hoist.
Pump Air Supply Valve (item 35 or 45): Used to control air to
the air motor and pump assembly. When the pump is in opera-
tion this valve must be open to allow air to flow to the air motor.
When servicing, relieving pressure, or operating the hoist, this
valve must be closed to stop air motor and pump operation
when the pump is removed from the drum.
OPERATION
1. Before operating, insure that the hoist is securely fastened
to the floor. All connecting bolts must be tightened securely.
Air connections and tube fittings are all tight and leak proof.
Fluid connections are tight and leak proof.
2. All fluid and air hoses are to be connected as required.
Installing a Material Drum:
3. Adjust the hoist regulator, item 44, to about 30 PSIG. Move
the Hoist Control Valve (item 10) to the raise position to
lift the pump clear of the rim of the drum. Adjust the hoist
regulator as required to a pressure high enough to raise the
pump clear of the drum with out rapid uncontrolled rising of
the pump. Move the Hoist Control Valve to the neutral posi-
tion to hold the pump in position.
4. Position the drum of lubricant on the mounting base, item 8,
so that the drum rests against the two gussets on the back
side of the base. (See Illustration 3.)
5. Adjust, if necessary, the location of the pump support, (item
29 or 53) to center the follower assembly over the top of
the drum. Tighten the bolts, (item 4) if an adjustment was
made.
6. Open the Air Vent (item 21) to allow air to vent from below
the follower as the follower is lowered into the drum.
7. Move the Hoist Control Valve (item 10) to the down posi-
tion and guide the follower into the drum of lubricant. As
the follower is lowered into the drum, air will vent from the
vent valve. Continue to lower the pump and follower into
the drum until it stops. If lubricant appears at the Air Vent,
close the Air Vent, (item 21).
8. Leave the Hoist Control Valve in the down position at all
times except when removing the drum from the drum.
9. Turn on the Pump Air Supply Valve (item 35 or 45) and
adjust the air pressure to the air motor and pump tube as-
sembly to prime the pump as required. See the owner’s
manual for the air motor and pump tube.
10. While in operation, as the pump removes material from the
drum, the pump will continue to drop into the drum, follow-
ing the level of material down to the bottom of the drum.
Note that no air pressure used to exert force on the pump
hoist to force the follower into the drum.
Removing a material drum:
11. When the pump follower reaches the bottom of the drum
and drum replacement is necessary the pump may be
removed from the drum as follows. Close the Pump Air
Supply Valve (item 35 or 45).
12. Move the Hoist Control Valve (item 10) to the raise position,
and press the Air Assist Push Button, (item 17), at the same
time. Hold the base of the drum into the slots formed in the
gussets on the mounting base with one foot while raising
the pump from the drum. Modulating the Hoist Control
Valve may be necessary to work the follower out of the
drum. If the follower hangs up at the drum chimes, it may
help to allow the drum to rise off the base slightly and allow
the Air Assist to force the drum off the follower.
13. When the follower reaches the top of the drum, release the
Air Assist Push Button, and place the Hoist Control Valve in
the neutral position to hold the pump in position while the
drum is replaced.
14. After removing the drum, remove any grease from the bot-
tom side of the follower in the area of the Air Vent check
ball (item 23), so that grease is not forced on top of the
follower when placing the follower back into the lubricant.

SERVICE
When service is required see the appropriate owner’s manual
for the pump, air motor or pump tube for the model in use.
Service on the hoist is limited to the hoist air cylinder assem-
bly and the follower assembly. All other hoist components are
not serviceable items.
WARNING! Before any service is attempted it is important to
disconnect the air supply to the pump and hoist unit and bleed
off all material pressure from the pump outlet and attached
hoses.
Air Cylinder Service
• The pump must be removed from the hoist to service the
air cylinder assembly. Disconnect all air lines between the
pump and hoist assembly. Disconnect the air line to the
follower assembly. The pump and pump mount (item 29 or
53) and the follower assembly, can be removed as a unit
from the pump support (item 56) by removing the four at-
tachment hex bolts, and washers, (items 4, 5, & 6). Place
the pump and follower on large sheet of clean paper or
cardboard to keep follower clean.
• Loosen set screw (item 12), and remove tube cap (item 11)
from upper support tube (item 15).
• Slide the upper support tube off of the lower support tube
(item 18) and set aside.
• The seal, (item 20) is accessable and may be replaced by
removing from the piston (item 19) and replacing with a
new seal.
• Carefully inspect the condition of the upper support tube
(item 15) before reassembly, checking for scratches or
damage to the inside surface. Before re-assembly, apply a
liberal coating of grease to the inside surface of the upper
support tube (item 15), piston (item 19), and seal (item 20).
• Reassemble in the reverse order of disassembly. Check all
tubing and connections for leaks.
Follower Service
• The follower must be removed from the bottom of the pump
for service. The pump does not need to be removed from
the hoist. To remove the follower, remove the pump and
follower from the material drum. Remove the drum from
the base of the hoist. Lower the pump and follower to the
base on top of a piece of clean cardboard or paper. Place
hoist control valve in neutral position.
• Disconnect the air line from the follower.
• Loosen the three hex screws, item 24, and slide the fol-
lower off the end of the pump tube. The follower may be
tight due to the O-ring seals (item 25) around the pump
tube.
• Place follower on clean flat surface with air vent and pump
tube bushing facing the top side.
• Remove the 18 hex screws (item 26), three segment rings
(item 27) and follower wiper ring (item 28)
• Inspect all components for wear or damage, replacing any
damaged or worn components.
• Re-assembly is the reverse of the disassembly process.
When installing the hex screws, item 26, take care not to
tighten too tight. The screws only need to be tight enough
to seal the wiper to the follower. There should be no deflec-
tion to the segment rings (item 27) when the screws are
tightened.
• Check for leaks and test after re-assembly.
Air Vent Service
• The Air Vent, items 21, 22, and 23, may be serviced without
removing the pump or follower from the pump. The pump
and follower must be removed from the drum. Lower the
pump and follower to the base on top of a piece of clean
cardboard or paper. Place hoist control valve in neutral
position.
• Remove the valve screw assembly (item 21) by turning
counterclockwise.
• Remove the retaining ring (item 23).
• The ball can now be removed through the slots on the sides
of the valve body.
• Inspect the ball for any signs of wear or damage. Replace
as necessary. Clean and inspect the valve body and fol-
lower surfaces where the ball is seated. Repair or replace
as necessary.
• Reassemble in the reverse order of disassembly. Do not
tighten the valve screw too tightly. It should only be tight
enough to form a seal. If tightened too tightly, damage to
the ball may occur.
