Description
Model 275260 is a pump hoist (without the pump) for use with 120 lb. (54 kg) and 400 lb. (181 kg) refinery container drums, 400 lb. (181 kg) follower, and the necessary hoses and fittings to perform a basic instal­lation († Fig. 1, page 3).
Model V350400HF includes the 275260 pump hoist and follower and a 3 in. (76 mm) PMV grease pump for use in 400 lb. (181 kg) container drums.
Model V450400HF includes the 275260 pump hoist and follower and a 4 in. (102 mm) PMV grease pump for use with 400 lb. (181 kg) container drums.
All models will place a pump and follower in position for insertion into a standard 400 lb. (181 kg) refinery container. The prim- ing action of these models is created by gravity and the vacuum created when mate­rial is pumped from the drum. The weight of the pump and follower, plus the effects of atmospheric pressure, work with the shape of the follower, to direct the material into the pump inlet. The follower will remain on top of the material until the container is emptied by the pump. When the follower reaches the bottom of the container, very little, if any, material is left in the bottom of the drum. The follower will work well with most drum liners in good condition.

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 detail in fig. 1, page 3 or the base may be used as a template for drilling and positioning anchors.
3 After hoist has been secured to the floor
reposition the pump support (46) by moving it down on the support tube (15) († fig. 3, page 6). Adjust the pump sup- port so that it is parallel to the floor and secure by tightening the six mounting bolts (4). This will keep the pump tube parallel with the support tube.
4 Mount pump to pump mount (29).
The holes in the pump mount are off center with the pump mount. When the pump mount is placed in the pump sup­port (46) the pump mount should be placed with the holes closest to the open end of the pump support († fig. 3, page 6). When attaching the pump to the mount (29) attach pump outlet body to pump mount with four 1/420 x 9/16 hex screw and washer assemblies (39) († fig. 3, page 6).
5 Place pump and mount into pump sup-
port (46) and loosely install hex bolts, lock washers, and flat washers (4, 5, and
6) through slots in support. Leave loose until final adjustments are made.
6 Assemble air inlet fittings († fig. 3,
page 6). Assemble the air regulator (44)
to the air inlet of the hoist as shown in the figure. Note that there is a 1/8 in. pipe plug packaged with each regulator for plugging the unused gage port in the regulator. Install this plug into the un­used port on the regulator (44) as shown.
7 Measure and cut a length of the supplied
1
/4 in. OD black polyurethane tubing to connect the air inlet to the regulator inlet († fig. 3, page 6). The tubing will simply push fit into the 1/4 in. fittings included with the model.
8 Assemble the air hose to the air coupler
(24). Make sure the ball valve (34) is closed and the hoist control valve (10) is in the down position. Attach air hose to source of filtered, regulated air. The air pressure should be set initially to about 40 psi (3 bar).
9 Adjust the hoist air regulator (44) for a
pressure of around 30 to 40 psi (2 to 3 bar). Check for air leaks in all connec­tions. Slowly move the hoist control valve (10) to the raised position and raise pump so the end of the pump tube will clear the primer assembly.
10 Attach the primer assembly to the end of
the pump tube. When assembling pump to the follower, a reducing adapter is used (38). 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 (14) securely. Apply some grease to the end of the pump tube and slide into the reducing adapter (38) until the pump tube is flush with the bottom of the follower. Tighten the three set screws (32) securely.
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.
WARNING
11 Raise the follower high enough to clear
an open 400 lb. (181 kg) container. Place the container under the follower and slide the drum back on the mounting base (8) until the bottom is against both gusset plates on the base. Adjust the position of the pump with respect to the drum by sliding the pump mount (29) in the pump support (46) until the follower is centered over the open drum. Tighten the hex bolts (4) through the slots in the pump support to secure the pump mount. Do not insert the follow-
er into the drum at this time.
12 Using the remaining polyurethane tub-
ing, attach to the open fitting on the 2-way air valve (17) mounted on the pump support (46) by pushing one end of the tube into the fitting until secure. († fig. 3, page 6). Thread the tubing down along the pump tube to the fitting (1) in the top of the follower assembly. Secure the tubing to the pump tube with two nylon wire ties, supplied with the assembly († fig. 2, page 4).
13 Check for proper air flow by pressing
button on 2-way air valve (17) making sure that air flows through check valve (30) and out under follower assembly.
14 Connect fluid hoses to pump outlet.
These models are supplied with a 1/4 in. (6 mm) ID high pressure hose (40) with
33
/64 in. (13 mm) female thread on both ends. Two male adapters (45) are sup­plied to adapt the hose to 1/4 NPT male for the pump outlet, and working end of the hose. Insert the hose adapters (45) 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
Refer to fig. 1, page 3.
Hoist control valve (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 (17)
Two-way air valve used to force air under the follower assembly to assist in lifting the pump and follower from the drum. The air assist is used in conjunction with the hoist control valve when removing the pump and follower from the drum.
Air vent (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 (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 damage the hoist.
Pump air supply valve (34)
Used to control air to the air motor and pump assembly. When the pump is in operation 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
Before operating, ensure 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.
All fluid and air hoses are to be connected
as required.
Installing a material drum
1 Adjust the hoist regulator (44) to about
30 psi (2 bar). Move the hoist control valve (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 position to hold the pump in position.
2 Position the drum of lubricant on the
mounting base (8) so that the drum rests against both gussets on the back side of the base.
3 Adjust, if necessary, the location of the
pump support (29) to center the follower assembly over the top of the drum. Tighten the bolts (4) if an adjustment was made.
4 Open the air vent (21) to allow air to vent
from below the follower as the follower is lowered into the drum.
5 Move the hoist control valve (10) to the
down position 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. Some lubricant may appear at the vent valve as it is lowered into the drum. This is normal. Close the air vent (21) after the follower stops moving.
6 Leave the hoist control valve in the
down position at all times except
when removing the follower from the drum. This will allow the follower to drop as the lubricant is depleted from the drum.
7 Turn on the pump air supply valve (34)
and adjust the air pressure to the air motor and pump tube assembly to prime the pump as required. Refer to the own­er’s manual for the air motor and pump tube.
8 While in operation, as the pump removes
material from the drum, the pump will continue to drop into the drum, following the level of material down to the bottom of the drum. Note that air pressure is not used to exert force on the pump hoist to force the follower into the drum.
Removing a material drum
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: 1 Close the pump air supply valve (34) to
stop the pump.
2 Move the hoist control valve (10) to the
raise position, and press the air assist push button (17) at the same time.
3 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.
4 Modulate the hoist control valve and air
assist push button as 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 while guiding the drum by hand.
5 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.
6 After removing the drum, remove any
grease from the bottom side of the fol­lower in the area of the air vent check ball (22), so that air will flow freely through the vent and grease is not forced on top of the follower when placing the follower back into the lubricant.
7
Air cylinder service
The pump must be removed from the hoist to service the air cylinder assembly. 1 Disconnect all air lines between the pump
and hoist assembly.
2 Disconnect the air line to the follower as-
sembly. The pump and pump mount (29) and the follower assembly, can be removed as a unit from the pump support (46) by removing the four attachment hex bolts, and washers, (4, 5, and 6). Place the pump and follower on large sheet of clean paper or cardboard to keep follower clean.
3 Loosen set screw (12), and remove tube
cap (11) from upper support tube (15).
4 Slide the upper support tube off of the
lower support tube (18) and set aside.
5 The seal (20) is accessible and may be
replaced by removing from the piston (19) and replacing with a new seal.
6 Carefully inspect the condition of the
upper support tube (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 (15), piston (19), and seal (20).
7 Reassemble in the reverse order of disas-
sembly. Check all tubing and connections for leaks.
Service
When service is required see the appropriate owner’s manual for the pump. Service on the hoist is limited to the hoist air cylinder assembly and the follower assembly. All other hoist components are not serviceable items.
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.
WARNING
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.
1 To remove the follower, remove the
pump and follower from the material drum.
2 Remove the drum from the base of the
hoist.
3 Lower the pump and follower to the base
on top of a piece of clean cardboard or paper.
4 Place hoist control valve in neutral
position.
5 Disconnect the air line from the follower. 6 Loosen the three screws (14 or 32) and
slide the follower off the end of the pump tube. The follower may be tight due to the O-ring seals (25 or 31) around the pump tube.
7 Place follower on clean flat surface with
air vent and pump tube bushing facing the top side.
8 Remove the 18 hex screws (26), three
segment rings (27) and follower wiper ring (28).
9 Inspect all components for wear or dam-
age, replacing any damaged or worn components.
10 Re-assembly is the reverse of the disas-
sembly process. When installing the hex screws (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 deflection to the seg­ment rings (27) when the screws are tightened.
11 Check for leaks and test after
re-assembly.
Air vent service
The air vent (21, 22, and 23) may be serviced without removing the pump or the follower from the pump. The pump and follower must be removed from the drum.
1 Lower the pump and follower to the base
on top of a piece of clean cardboard or paper.
2 Place hoist control valve in neutral
position.
3 Remove the valve screw assembly (21)
by turning counterclockwise.
4 Remove the retaining ring (23). 5 The ball can now be removed through the
slots on the sides of the valve body.
6 Inspect the ball for any signs of wear or
damage. Replace as necessary. Clean and inspect the valve body and follower sur­faces where the ball is seated. Repair or replace as necessary.
7 Reassemble in the reverse order of disas-
sembly. 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.
