Installation
Grounding
Pump
NOTE: The reference numbers in the following section
refer to Parts, page 12.
NOTE: Pipe/thread sealant is user supplied, do not use
the PVC cement supplied with the product.
The oil transfer pumps are positive displacement
pumps. The motors are drip proof rated and have sealed
bearings and require minimal maintenance. All models
come with hose, nozzle, 34 in. (864 mm) suction tube
assembly, and bung adapter.
Mount Pump on Drum
1. Install the bung adapter (14) in the drum bung and
tighten.
2. Assemble the suction tube sections (18) by applying
PVC cement (21) to the inside diameter of the PVC
couplers (19, 20). Make sure that the PVC cement is
applied to the complete inside diameter and slide
the pipe sections into the coupler with a twisting
motion.
3. Apply pipe sealant (not supplied, do not use the
supplied PVC cement) to the threaded end of the
suction tube, then screw the tube into the pump inlet
port, making sure that the tube is tight.
4. Insert the suction tube attached to the pump
through the bung adapter, and lower the pump onto
the bung adapter. Position the pump, as desired,
then tighten the swivel nut (23) to the bung adapter
(14).
Mount Hose and Nozzle
1. Before connecting the hose to the pump, pour 8 z.
(0.24 l) of oil into the pump outlet port so that the
pump does not run dry during the initial startup.
2. Apply pipe sealant to the male threads of the elbow
(12), then secure the elbow into the outlet port.
3. Apply pipe sealant to one end of the hose assembly
(17), then twist the hose end into the elbow.
4. Apply pipe sealant to the other end of the hose
assembly (17).
5. Apply thread sealant onto the nozzle (15) end that
connects to the ball valve (16).
6. Fasten the ball valve and nozzle (15, 16) onto the
hose assembly, positioning the nozzle (15) down for
dispensing.
Electrical Installation
12 V DC
The 12 VDC model is not shipped with a power cord
since the installation will determine the length of the
power cord.
1. Verify the on/off switch is in the OFF position.
2. Remove the wiring junction box cover by removing
the four (4) screws.
3. Bring the 12 VDC, 10 AWG supply wire through the
junction box strain relief.
4. Tighten the strain relief.
5. Connect the motor red wire (+) and the motor black
wire (-) to the supply wires using nuts (user
supplied).
6. Reattach the wiring junction box cover with the four
(4) screws.
The equipment must be grounded to reduce the risk
of static sparking. Static sparking can cause fumes to
ignite or explode. Grounding provides an escape wire
for the electric current.
All electrical wiring must be done by a qualified
electrician and comply with all local codes and
regulations.

Operation
3A8569A 7
Operation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn off and disconnect the power supply.
2. Trigger the dispense valve into a grounded waste
container to relieve pressure.
Duty Cycle
The pump is designed to operate for a 50% duty cycle. It
can operate up to a maximum of 30 minutes of run time,
with an equal amount of down time.
Pump Start Up
1. Check that the ball valve is in the off position.
2. Turn the power switch, located on the terminal box,
to the ON position to start the pump.
NOTE: The pump has an internal bypass valve
(Pressure Relief Valve) that opens when the pump
discharge pressure exceeds 65 psi. If the flow is
blocked, the fluid will bypass within the pump.
3. Insert the nozzle (15) into the container and open
the ball valve (16) to dispense fluid.
4. Turn the switch to the OFF position immediately
after finishing dispensing.
5. Close the ball valve (16).
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid and moving
parts, follow the Pressure Relief Procedure when you
stop dispensing and before cleaning, checking, or
servicing the equipment.
NOTICE
Never allow the pump to operate dry. Make sure that
the pump has fluid in it when the pump is initially
installed. Do not run the pump for more than five (5)
minutes with the pump discharge blocked. Do not
operate the pump continuously more than 30 minutes
in one (1) hour. Failure to follow these instructions can
result in damage to the pump.

Recycling and Disposal
83A8569A
