MOUNTING

FLEXIBLE

HOSE

RIGID

PIPE

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

r below the fluid level. For most applications, no more

o 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)

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

perate according to air supply. Flow and pressure can

o 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).

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.

WARNING

DO NOT PUMP GASOLINE OR FLAMMABLE LIQUIDS OR USE WHERE FLAMMABLE VAPORS ARE PRESENT.

If used with C0

or N2be sure the area is

well ventilated.

CAUTION:

Do not clean or service FLOJET pumps, hoses or valves while the system is pressurized. Plastic CO2air 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.

DISASSEMBLY PROCEDURE

Remove all gas lines and suction/discharge fittings from pump. This is accomplished by using a flatbladed screwdriver. Slide the retaining clips away from the gas “in,” suction and discharge fittings. Then pull the fitting away from pump body.

Using a 5/16” (8 mm) socket, remove the 4 nuts and washers and pull out the body bolts.

The end caps, mounting brackets will separate from the pump. Grab a piston in each hand and twist each side counterclockwise. Remove the piston, diaphragm, piston seal and retaining washer from one side of the drive shaft.

Place drive shaft into a vise with wood block jaws and rotate counterclockwise to release old diaphragm. Install new diaphragm and hand tighten.

CAUTION: Do not damage the surface of the drive shaft.

Using a razor blade or sharp knife, cut label on the front of the pump along the seam in center of body.

With pump label facing you, slowly pull body apart. Disconnect exhaust hose from muffler and pull spool valve stem from body. Discard body gasket and old spool valve subassembly.

To assemble new spool valve subassembly, insert internal exhaust hose spring into exhaust hose. Connect hose to spool valve. Mount torsion springs into spool

valve straight side first. Push torsion springs through spool valve to bent/hook end. Lubricate spool valve stem and insert stem into left side of pump body making sure torsion springs are positioned in retaining niches. Carefully push spool valve into pump until torsion springs snap inward and lock into place. Reconnect exhaust hose to muffler fitting.

CAUTION: If exhaust hose is not reconnected to muffler fitting, pump will not operate.

Position new body gasket and the two o-rings and press pump body together. Reinsert gas “in’’ fitting, discharge and suction fitting into pump and slide retainer clips over fittings until they snap into place. This will help hold the pump together during assembly.

Lubricate and carefully reinsert the drive shaft through the pump body. Install new diaphragm and piston assembly onto drive shaft and hand tighten. Note positioning and direction each part is facing.

Position end caps onto pump body. Insert body bolts through pump body. Install washer, split washer and hex nut on each bolt.

Note: Remember to insert mounting bracket into niches on the body before installing end caps and bolts.

With a 5/16” (8 mm) nut driver, alternately tighten each body bolt maintaining even pressure around pump body. Using a 5/16” (8 mm) torque wrench tighten body bolts to 20 inch lbs.
