Installation
The oil transfer pumps are positive displace-
ment pumps. The motors are drip proof rated
at 3/4 hp. The motors have sealed bearings
and require minimal maintenance. All models
come with hose, nozzle, 34 in. (864 mm) suc-
tion tube assembly, and bung adapter.
When unpacking check for shipping damage.
Report any shipping damage to delivering car-
rier immediately. See Parts, page 8.
Mounting Pump on Barrel or
Tank
1. Install bung adapter (14) in barrel bung and
tighten.
2. Assemble suction tube sections (18) by
applying PVC cement (21) to the inside
diameter of the PVC couplers (19, 20).
Make sure 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 the supplied PVC
cement) to the threaded end of the suction
tube and then screw the tube into the pump
inlet port. Make sure tube is tight.
4. Insert suction tube already attached to the
pump through bung adapter and lower the
pump onto the bung adapter. Position the
pump as desired and tighten swivel nut to
the bung adapter (14).
Mounting Hose and Nozzle
1. Before connecting hose to the pump, pour
8 oz (0.24 l) of oil in the pump outlet port so
that the pump does not run dry during initial
start-up.
2. Apply pipe sealant to male threads of the
elbow (12) and screw the elbow into the
outlet port.
3. Apply pipe sealant to one end of hose
assembly (17) and screw hose end into the
elbow (12).
4. Apply pipe sealant to other end of hose
assembly and screw the nozzle (15, 16)
onto the hose.
For tanks deeper than 36 in. (914 mm) you
will need a standard 1 in. (25 mm) pipe
with 1 in. npt threads on one end. If pump-
ing used oil, install suction screen assem-
bly, Part No. 260306, to filter large
contaminants.
For tanks less than 36 in. (914 mm) deep,
cut the suction tube to leave about 2 in. (21
mm) of clearance between the bottom of
the suction tube and the bottom of the
tank.
