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.
