WARNING

Installation
4311307E
Installation
These On-Demand dispensing pumps are
positive displacement gear pumps. The motors
are totally enclosed 115 VAC or 12 VDC units,
with sealed bearings, and require minimal
maintenance.
When unpacking, check for shipping damage.
Report any shipping damage to delivering car-
rier immediately. See Parts, page 10.
System Plumbing
The On-Demand pumps deliver a constant
output flow even with a varying load. It is
important the system plumbing be of adequate
size to handle the rated pump flow at a pres-
sure drop that is less than maximum rated
pressure for the pump model used. All plumb-
ing and hoses used in the installation should
have a pressure rating compatible with the
pump selected.
Flow and pressure switch settings
If the system pressure drop at the rated pump
flow is greater than the pressure switch setting,
the motor will cycle on and off when the hose
valve is opened to dispense fluid. If this hap-
pens, reduce system pressure by using a
larger diameter hose or using a less restrictive
valve.

Mounting Pump on Tank
1. Install supplied bung adapter fitting (12)
into the tank bung port and tighten.
2. Use a 3/4 in. (19 mm) steel or PVC pipe
with 3/4 npt pipe threads on one end as a
suction tube.
3. Measure the length from the top of the
bung adapter to the bottom of the tank. Cut
the suction tube length to 1/2 in. (13 mm)
less than this measurement.
4. Apply pipe thread sealant to suction tube
threads and install pipe into pump inlet.
5. Insert suction tube assembly through bung
adapter and lower pump onto the bung
adapter.
6. Position the pump so that the outlet port is
in the desired position. Tighten the swivel
nut on the pump to the bung adapter.
Connection Hose
A flexible hose must be used to connect the
pump outlet to solid plumbing. The pump outlet
port is 1/2 NPT female.
Electrical Installation
115 VAC models
Models 260110, 260111, 260113, and 260114,
use a 115 VAC, single phase, 60 Hz motor.
The electrical circuit supplying the motor must
be on a circuit breaker and be rated to carry a
minimum current greater than the motor full
load current.
Motor current ratings:
260110: 10.6 amps full load
260111: 13.6 amps full load
260113: 18.0 amps full load
260114: 21.0 amps full load
1. Turn power switch OFF.
2. Remove conduit box cover by removing
screws in the opposite corner of cover. A
1/2 in. (13 mm) conduit opening is provided
on the right side of the conduit box just
below the pressure switch.
3. Connect the 115 VAC to the black wire in
the conduit box.
4. Connect the neutral supply wire to the two
white wires in the conduit box. Make sure
both white wires are connected. The small
diameter wire is the pressure switch.
5. Connect ground wire to the motor housing
using the green screw in the motor housing
inside the conduit box.
6. Replace conduit cover, making sure gasket
is in place.
7. Finish wiring the electrical circuit to the
breaker box.

Installation
6311307E
12 VDC model 260112
Motor current rating: 62 amps full load. Use 8
AWG or larger for supply wires.
1. Turn power switch OFF.
2. Use an appropriate size ring terminal to
attach the black (negative) supply wire to
the negative post near the back of the
motor. Ensure the existing small black wire
remains on the post.
3. Use an appropriate size ring terminal to
connect the red (positive) supply wire to the
relay post (16) at the front of the motor.
This post is the one closest to the pump
inlet and outlet. Do not connect the positive
supply wire directly to the positive post of
the motor or the motor will run continuously.
Ensure the small red wire remains on the
front post.
Priming
1. Attach the connection hose to the outlet of
the pump. Insert the opposite end of the
hose into the tank through the fill opening.
2. Turn power switch ON. The pump should
prime in a few seconds. If priming does not
start, see steps 4-6.
3. When pumps starts to prime, turn power
switch OFF. Go to step 7.
4. If priming does not start, remove the outlet
fitting (18) by disconnecting the small diam-
eter sensing hose (17) from the outlet fitting
and remove the fitting.
5. Fill the outlet port of the pump to within 1/2
in. (13 mm) of the top.
6. Replace the outlet fitting and reconnect the
sensing hose. Repeat step 2. Once the
pump is primed the inlet check valve will
prevent loss of prime.
7. Attach the connection hose to the system
plumbing.

Operation
311307E 7
Operation
The on-demand dispensing pumps sense the
pump outlet pressure and turn the pump on or
off depending on the pressure. When a dis-
pensing valve is opened, the pressure in the
system drops and the pump will start pumping
fluid. When the dispensing valve is closed, the
pressure increases and the pump will stop.
1. To start the pump, turn power switch ON.
Power switch is located on the back side of
the motor.
2. Place the outlet of the dispensing valve into
the fill tube of the vehicle.
3. Open the dispensing valve to the full open
position until the desired amount of fluid
has been dispensed.
4. To stop dispensing, close the dispensing
valve.
When system is not in use, always turn power
switch OFF. Failure to do so can result in a
spill if a hose ruptures or a leak occurs in the
system plumbing. If a leak occurs, pressure
will drop in the system signaling the pump to
turn on.
See Parts, page 10 for reference numbers.

Troubleshooting
8311307E
Troubleshooting
Problem Cause Solution
Motor runs but pump will not
prime.
Motor rotation wrong. Check wiring instructions for
possible problems (260112
only).
Dirt under pressure relief valve
or seal.
Remove pressure relief valve
and inspect, clean, or replace if
damaged.
Oil depth too high to prime. See Priming Pump, page 6.
Worn or damaged gears. Remove cover and inspect
gears. Replace if worn or
damaged.
Oil level low. Refill tank.
Cover seal damaged. Replace if worn or damaged.
Air leak in suction tube. Inspect all joints in suction
tube, make sure all joints have
sealant applied.
Air lock in system. This may occur if filter or meter
or automatic shut-off nozzle is
used. If this occurs, fill pump
and meter with fluid through
top of pump.
Motor does not run at proper
speed.
Check electric connections.
Ensure supply voltage is at the
proper level.
Oil leaking in motor mount. Faulty or damaged motor shaft
seal.
Replace shaft seal (4).
Motor shaft worn. Replace motor (5) if shaft has
groove worn in seal area.
Unit pumps but output flow is
low.
Air leak in suction tube. Check to make sure all joints in
suction tube are sealed.
Suction tube too close to tank
bottom.
Suction tube must have a 2 in.
(51 mm) minimum clearance.
Tank empty. Refill tank.
Tank not vented. Tank must be vented to atmo-
sphere.
Worn or damaged gears. Remove cover and inspect
gears (3). Replace if worn or
damaged.
Damaged motor. Replace motor (5).
Clogged hose or nozzle. Inspect and clean.

Troubleshooting
311307E 9
Motor stalls when nozzle is
closed.
Bypass relief valve is stuck. Inspect relief valve, making
sure ball is free. Replace if
damaged.
Low supply voltage. Check supply voltage.
Gears damaged and binding. Inspect gears. Gears should
turn freely. Replace if dam-
aged.
Faulty pressure switch. Replace pressure switch (20).
Motor overheating. Gears binding. Check to make sure gears turn
freely on shaft.
Clogged hose or nozzle. Inspect and clean if required.
Operating pump more than 30
minutes continuous duty.
Limit operation to 30 minutes
per hour.
Switch will not turn pump on. Blown fuse or tripped breaker. Replace fuse or reset breaker.
Electrical problem. Check that supply voltage is
proper and getting to pump.
Defective pressure switch (20). Check and replace if defective.
Damaged or defective motor. Check motor (5), replace if
damaged or defective.
Outlet pressure above pres-
sure switch limit.
Open dispense valve to relieve
pressure.
