several feet from the tank, above or below the fluid level. For
most applications, no more than 4 feet above the fluid level is
recommended. Note: This is not a submersible pump.
ecure Pump to desired fixture by inserting screws through the
S
rubber grommets in the baseplate of the pump. Ports must be
facing down. The pump must be protected by a housing able
to withstand the impact of a steel half ball of 25mm with a mass
of 1Kg and an energy of 7J. Refer to EN 13463-1 Par 13 for
urther details.

HOSE CONNECTIONS
Liquid In - Use 3/8”, 1/2”, or 3/4” I.D. reinforced hose or
equivalent. Avoid sharp bends that could restrict flow or
cause hose to collapse under vacuum.
Liquid Out - Use 3/8”, 1/2”, or 3/4” I.D. reinforced hose for
discharge tube. 3/4” I.D. hose must use 90° elbows when
using large muffler.
Air In - Make sure air regulator is set at zero. Use reinforced
1/4” I.D. hose. Connect “Air In” to air supply fitting on
regulator. If pumps are installed in an enclosed area, it is
recommended to connect a hose to the air discharge port
(exhaust) and vent air to atmosphere (Requires small
exhaust port PN# 20756103B not included)
.
PLUMBING
Use a flexible hose to avoid
excess stress on pump ports.
DO NOT crimp or kink hose.
All hose should be the same
size as the pump port fittings.
All fittings and hose must be
compatible with fluid being
pumped. It is recommended to use plastic fittings only.
The use of check valves in the plumbing system could
interfere with the priming ability of the pump. If unavoidable,
check valves in the pumping system must have a cracking
pressure of 2 PSI or less.
Use a minimum 40 mesh strainer or filter in the tank or pump
inlet line to keep large foreign particles out of the system.
Liquid inlet port must be equal to or larger than the liquid
outlet port.
OPERATION
At start-up, regulate air pressure to desired setting. For
most installations 20 PSI (1.4 bar) inlet will be adequate,
although DO NOT go below 20 PSI. Pump will operate
according to air supply. Flow and pressure can be adjusted
by increasing or decreasing air pressure to accommodate
varying product viscosities, length of lines or other
installation conditions. Review flow curves located on page
1 for further assistance. High viscosi ty fluids and hose
length will limit priming distance.
Compressors must have dryers and/or a water separator in
the air distribution system. Pumps that fail due to water in
the air chamber will not be covered under the limited
warranty.
Plastic air inlet ports do not have a check valve. Prior to
cleaning or servicing, purge the pump by carefully tilting the
pump so ports are facing up and remove suction line from
source. Turn air off and disconnect air inlet line. (Standard
brass air inlet ports have a check valve).
DISASSEMBLY PROCEDURE
First, remove inlet air line, muffler and suction/discharge
line from the pump. This is accomplished by using a flatbladed screwdriver to slide the retaining clips away from the
air inlet, muffler and suction/discharge fittings and pulling
the fittings away from the pump body. Now remove the muffler by sliding the retaining clip away from the muffler base
and pulling the muffler out of the pump body.
Using a Phillips screw driver remove the seven (7) screws
from the front end cap followed by the (7) screws from the
rear end cap. With the front end cap facing up and the rear
end cap facing down on the workbench, position a flat bladed screw driver into the slot located above the muffler port
and just below the pad marked Air/C02and lift off the front
end cap. The rear end cap can be removed by placing the
flat bladed screwdriver under the fully opened port retaining
clip and lifting off.
Note the position of the suction and discharge valves before
removing them from the pump body. The first diaphragm is
removed from the pump shaft by unscrewing in a counter
clockwise direction. The second diaphragm is removed by
placing the flat tip of a screwdriver into the exposed slot at
the end of the pump shaft and unscrewing the diaphragm
from the shaft. To remove the flange housing, place the tip
of the flat bladed screw driver into the air bleed hole on the
lower side of the flange housing and lift up the lower end
separating the flange housing from the pump body.
The slide valve assembly and pump shaft can be removed
by simply pulling them from the pump body. The pump shaft
then can be removed from the slide valve yoke assembly.
REASSEMBLE PROCEDURE
Assemble the slide valve and pump shaft with the yoke
placed between the (2) bumpers on the pump shaft. Install
the slide valve/pump shaft assembly into the pump body
making sure the O-rings in the slide valve are in place. To
install the flange housing, prelube the o-ring with Parker
Super “O” Lube and install on flange housing and place
housing over the pump body aligning the flange housing
with the pump body ribs pressing it into place.
Install the first diaphragm and O-ring on to the pump shaft
by threading on to shaft using a flat blade screwdriver to
hold the pump shaft until the diaphragm is tight. Install the
second diaphragm and O-ring on to the pump shaft turning
clockwise until tight.
Install the suction valves with springs facing into the pump
body and the discharge valves with the springs facing out.
See arrows on pump rear end cap below suction and
discharge ports.
Install the port retainer clips (large) into the pump end cap
(mounting base) and install the seven (7) Phillips screws
into pump body and cross tighten until snug and then cross
torque to 22-24 inch pounds. Install port retaining clips
(small) into the pump body with tabs facing out. Position the
front end cap and install the seven (7) Phillips screws into
pump body and cross tighten until snug and then cross
torque to 22-24 inch pounds.
Install the muffler in the center port by pushing it in and
sliding the retainer clip into place. Install the suction and
discharge ports and the air inlet port fitting and slide the
retainer clips in place. Check for leaks.

GENERAL SAFETY INFORMATION
Follow all safety codes and the Occupational Safety and
Health Act (OSHA).
These User Instructions contain specific safety markings
where non-observance of an instruction would cause hazards.
The specific safety markings are:
This symbol indicates safety instructions where non-compliance
would affect personal safety and could result in serious injury.
CAUTION
This symbol indicates safety instructions where noncompliance will involve some risk to safe operation and personal
safety and would damage the equipment and or property.
Do NOT pump Gasoline or flammable fluids with flash
point below 98°F (37°C) Explosion or serious injury may occur.
Incompatible fluids may cause premature failure of the
pump. It is the customer’s responsibility to ensure that
fluids are compatible with pump materials.
If used with C02or N
ventilated.
CAUTION
If pump is to be used in high flow, low pressure
be sure the area is well
2
applications, adjust air pressure to 20 PSI (1.38 bar) above
discharge pressure.
When using high pressure gas tanks make sure a
secondary regulator is used to avoid accidental damage to
pump.
CAUTION
Do not clean or service FLOJET pumps,
hoses or valves while the system is pressurized.
CAUTION
This is not a submersible pump - use only in
dry environments.
PREVENTIVE MAINTENANCE TIPS
Tips to help prolong your pump’s life.
• If pumping liquid other than water, pump should be
flushed with water (if applicable) after every use.
•
Before freezing conditions occur, pump must be liquid free.
• If mounting pump in an outdoor environment, shield
pump from environmental extremes (i.e. sunlight, water
from washdown spray, rain, etc.). Avoid high heat and
humid installations.
• When using an air compressor, use an inline air dryer
(PN# FJ520B) before the pump to limit water build-up.
WARRANTY
CAUTION
Do NOT Exceed 100 PSI (6.9 bar) Air Inlet
Pressure.
CAUTION
Continuous operation above 120°F (48.9°C)
will reduce pump life.
CAUTION
Inlet air must be dry and oil free - use an air/oil
filter and air dryer.
CAUTION
To Reduce the risk of static sparking, ground the pump
and all other equipment used or located in the pumping
area. Check your local electrical code for detailed
grounding instructions for your area and type of equipment.
Mount with ports facing down.
RETURN PROCEDURE
Prior to returning any product to FLOJET, call customer
service for an authorization number. This number must be
written on the outside of the shipping package. Place a note
inside the package with an explanation regarding the
reason for return as well as the authorization number.
