WARNING

FIRE AND EXPLOSION HAZARD

When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be

aware that flammable fumes can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well-ventilated area.

• Eliminate all ignition sources, such as cigarettes and portable electric lamps.

• Ground all equipment in the work area.

• Keep work area free of debris, including rags and spilled or open containers of solvent and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.

• Use only grounded hoses.

•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment until

you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

BURN HAZARD

Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe

burns:

• Do not touch hot fluid or equipment.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system

component. See Technical Specifications in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical

Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For

complete information about your material, request Safety Data Sheets (SDSs) from distributor or

retailer.

Typical Installation

FIG. 1: Typical Installation

Installation

63A8569A

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

Recycling and Disposal

End of Product Life

At the end of the product’s useful life, dismantle and

recycle it in a responsible manner.

• Perform the Pressure Relief Procedure.

• Drain and dispose of fluids according to applicable

regulations. Refer to the material manufacturer’s

Safety Data Sheet.

• Remove motor and power cord components.

Recycle according to applicable regulations. 

• Deliver remaining product to a recycling facility.

Troubleshooting

hose, or nozzle, and replace as

needed.

The motor stalls when the

nozzle is closed.

The bypass relief valve is stuck. Remove and inspect the pressure

relief valve. Clean, or replace if it is

damaged.
