MOUNTING
The FLOJET N5100 Series self-priming pump should be
mounted in a dry and adequately ventilated area. This
pump can be mounted 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.
This
is not a submersible pump.
Secure Pump to desired fixture by screws through the
mountng bracket.
Ports must be facing down.
HOSE CONNECTIONS
Product In - Use 3/8” (10 mm), reinforced, flexible,
non-collapsible hose or equivalent. Avoid sharp bends
that could restrict flow or cause hose to collapse under
vacuum.
Product Out - Use reinforced 3/8” (10 mm) I.D. hose
for discharge tube.
Gas In - Make sure gas regulator is set at zero. Use
reinforced 1/4” (6 mm) hose. connect “Gas In” to gas
supply fitting on regulator. If pumps are installed in an
enclosed area, it is recommended to connect a hose
to the gas discharge port (exhaust) and vent gas to
atmosphere. (Requires ‘small’ exhaust port)
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 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.
OPERATION
At start-up, regulate gas pressure to desired setting. For
most installations 20 PSI (1.4 bar) inlet will be adequate,
although DO NOT go below 20 PSI (1.4 bar). Pump will
operate according to air supply. Flow and pressure can
be adjusted by increasing or decreasing gas pressure to
accommodate varying product viscosities, length of
lines or other installation conditions. Review flow curves
located on page 1 for further assistance. High viscosity
fluids and hose length will limit priming distance.
IF PUMP IS T0 BE USED IN HIGH FLOW, LOW
PRESSURE APPLICATIONS, ADJUST GAS PRESSURE
TO 20 PSI (1.4 BAR) ABOVE DISCHARGE PRESSURE.
CONTINUOUS OPERATION AT 120°F (49°C) WILL
REDUCE PUMP LIFE.
AIR MUST BE DRY AND OIL FREE.
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.
GENERAL SAFETY INFORMATION
Protect yourself and others by observing all safety
information.
Follow
all
safety
codes
and
the
Occupational Safety and Health Act (OSHA).
DO NOT PUMP GASOLINE OR
FLAMMABLE LIQUIDS OR USE WHERE
FLAMMABLE VAPORS ARE PRESENT.
If used with C0
2
or N
2
be sure the area is
well ventilated.
CAUTION:
Do not clean or service FLOJET pumps, hoses or valves
while the system is pressurized. Plastic CO
2
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. (Brass
air inlet ports have a check valve.)
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.).
• When using an air compressor, use an inline air dryer
placed before the pump to limit water build-up.
