WARNING

Installation

4312009A

Installation

These pumps are positive displacement gear

pumps. The AC motors are 115 VAC, and use

UL and CSA listed TENV motors. The motors

use sealed bearings and require minimal main-

tenance. These pumps are for use with motor

oil, hydraulic fluid, antifreeze, gear lubes and

other oil-based products. The package

includes a bung adapter for mounting on any

standard 2 inch barrel or tank bung.

When unpacking check for shipping damage.

Report any shipping damage to delivering car-

rier immediately. See Parts, page 6.

Mounting Pump on Barrel or

Tank

1. Install bung adapter in 2 in. bung and

tighten.

2. Use a 1 in. (25 mm) steel or PVC pipe with

1 in. npt pipe threads on one end as a suc-

tion tube.

3. Cut tube to a length 1/2 in. (13 mm) less

than the distance from the top of the bung

to the bottom of the tank.

4. Apply pipe sealant to threads and install

pipe into pump inlet.

5. Insert the suction tube through the bung

adapter into the tank, and lower the pump

onto the bung adapter.

6. Tighten swivel nut on pump to the thread

on the bung adapter.

7. The pump outlet port is a 3/4 in. npt pipe

port. Make sure hose or pipe used on the

pump discharge is rated greater than the

maximum working pressure rating of the

pump

8. Fill pump outlet with fluid to aid initial prim-

ing.

Mounting Pump In-line

The pump has a 1 in. npt inlet and a 3/4 in. npt

outlet.

If you are pumping used oil, install suction

tube assembly with inlet suction screen to

filter large contaminants.

If tank depth is greater than 60 in. (1524

mm), an intake check valve may be

required to retain pump prime.

If you are pumping used oil, install a suc-

tion screen to filter large contaminates.

Operation

312009A 5

Electrical Installation

115VAC

The pump comes pre-wired with a 30 in. (762

mm) power cord with a 3 prong grounded plug.

Power to the pump must be 115 VAC, 60Hz,

single phase. If an extension cord is used it

should be a 3-wire cord with a ground.

To permanently hardwire the pump, remove

the conduit box cover and remove the power

cord strain relief. The conduit box wiring open-

ing is for a 1/2 in. conduit pipe. The motor is

115 VAC single phase, requiring a 3-wire

grounded electrical service.

Operation

See Parts, page 8 for reference.

1. To start the pump, turn power switch ON.

Power switch is located on the back side of

the motor.

2. The pump has an internal bypass valve that

will open when the pump discharge pres-

sure exceeds 150 psi (1.03 MPa, 10.3 bar).

If flow is blocked the fluid will bypass within

the pump.

3. Transfer or dispense fluids by opening the

required valves in your system.

4. Immediately after dispensing, turn power

switch to off position.

Before servicing, turn pump off and open

the nozzle to relieve pressure.

CAUTION

Do not operate pump dry. Make sure pump

has fluid in it when pump is initially installed.

Do not run the pump for more than 2 minutes

with the pump discharge blocked.
