GREAT PLAINS HP-100 Dual-Flo User manual

The GPI HP-100 DUAL-FLO
®
Petroleum Hand Pump is de-
signed to manually pump petroleum products compatible
with aluminum and Buna-N. The user has the flexibility of
operating the pump at two flow rates. A setting of 1/2-gallon
provides faster high-capacity flow. A 1/4-gallon setting al-
lows for easier pumping of fluids. The HP-100 Hand Pump is
designed for use on a tank with a 2-inch bung.
Read Me!
Observe standard precautions when handling fuel.
•Keep fuel away from open flame or spark.
•Do not refuel vehicles or equipment with engines running
or while equipment engine is hot.
•Do not smoke while refueling.
Use the HP-100 Hand Pump only with petroleum products
such as diesel fuel, kerosene, and gasoline. This equipment
should not be used to pump chemicals.
Damage Inspection
Upon receipt of your pump system, carefully inspect visible
components for any damage that may have occurred during
shipping. Note that the pump includes a suction pipe, dis-
charge hose, and nozzle. If any parts are damaged or
missing, please contact your distributor.

Install Pump on Tank
1. Before installing the pump, clean the tank interior of all dirt
and foreign material.
2. Lubricate the threads of the inlet cover with Teflon
®
tape
or a thread-sealing compound approved for use with
petroleum fuels.
3. Extend the adjustable suction pipe to its full length and
carefully insert it into tank opening. The suction pipe will
adjust to the length needed and rest on the bottom of tank.
NOTE: The suction pipe supplied has a variable length of 22
to 40 inches. If additional length is needed, order the 15-
inch Suction Pipe Extension Kit.
4. Thread the inlet fitting of the pump onto the tank and turn
the pump to tighten snugly.
NOTE: To prevent the buildup of pressure and possible fuel
leakage through the nozzle, make sure the tank is vented.
Install Hose and Nozzle Assembly
Apply 3 to 4 wraps of Teflon
®
tape to the threaded end of the
hose and hand-tighten into the outlet cover until snug.
Install Handle
The HP-100 Hand Pump gives the operator a choice of two
flow settings:
•1/4 gallon setting has low resistance and pumps 1/4
gallon per stroke cycle.
•1/2 gallon setting has higher resistance and pumps 1/2
gallon per stroke cycle.
Volume per stroke is determined by connecting the piston
shaft to the appropriate handle setting as outlined below.
NOTE: Clevis pins may be installed from either side of handle.
1. Slide the handle grip onto the pump handle.
2. To install the links on the pump, insert a long clevis pin
through the link ends and the pump’s link holes. Secure
with a small cotter pin. (Figure 1)

4. Insert a screwdriver in the piston shaft of the pump and
pull the piston out. Install the shaft on the handle at either
piston hole by placing a short clevis pin through the handle
and the piston shaft end and securing with the hitch clip pin.
NOTE: Select the upper piston hole on the handle for the 1/2-
gallon setting (Figure 3) or the lower piston hole for the
1/4-gallon setting. Flow settings can be changed at any
time by repositioning the piston shaft on the handle.
To Dispense Fluid
1. Remove the nozzle from its holder and insert into the
receiving tank of the equipment or vehicle.
2. Choose a handle setting for the desired flow rate:
–1/4-gal. setting for low-volume, low-resistance pumping
–1/2-gal. setting for high-volume, high-resistance pumping
3. To operate pump, manually move the handle in a push/
pull motion.
4. After dispensing the desired amount of fluid, drain the
hose and nozzle. Place the nozzle in its holder and return
the handle to its upright storage position.
During daily use, the GPI HP-100 Hand Pump is essentially
maintenance free. However, the pump should be inspected
periodically for signs of leakage. If leaks are present, make
appropriate repairs. Refer to the Troubleshooting section.

OPERATION & MAINTENANCE
NOTE: Lock the handle to the pump by pushing the handle
against the pump and inserting a padlock through either
of the top holes in the handle and through the pump’s lock
hole. (Figure 4)
SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION
A. FLUID LEAKS AROUND 1. Packing seals settled Tighten two screws on the retainer and torque to approximately 20 lb. in. (or hand
SHAFT SEAL tighten then another half turn until leak stops)
2. Seals worn Remove the two screws on the retainer and remove the retainer and bearing. Remove
all three seals and replace.
B. FLUID LEAKS AT 1. Anti-siphon valve or Replace vent plug assembly. Remove the black cap. Remove old vent plug assembly
ANTI-SIPHON VALVE O-ring damaged by turning counterclockwise. Install new vent plug assembly. Replace cap.
C. LOW FLOW RATE 1. Inlet screen clogged Remove the pump from the tank. Remove the suction pipe, spacer, and inlet
screen from the bottom of the pump. Clean the inlet screen and assemble. Place
the pump on the tank using installation instructions.
2. Suction pipe leak Remove the pump from the tank. Inspect the spacer and suction pipe to ensure
they are not worn or damaged. Replace as necessary and install the suction pipe
and pump again using installation instructions.
3. Piston ring or liner Remove the piston cover and inspect the piston ring and liner. Scoring and
worn severe scuffing on the liner indicates wear. If necessary, install an Overhaul Kit.
4. Piston cracked Remove the piston cover and inspect the piston. Install an Overhaul Kit, if necessary.
D. PUMP SEIZED 1. Debris in piston or Disassemble and clean the piston and liner. Check for debris lodged in the
liner piston ring or behind the liner. Small dimples in the liner indicate dirt, debris or
welding slag contaminants in the tank. Replace the piston ring and liner. If
appropriate, flush the tank of all contaminants.
