OPERATION

With pump intake connected to supply tank or through hull fitting, and operation switch off, open outlet valve, then turn pump switch on. Water will begin to flow, when water is free of air turn valve off. When valve is shut off pump will stop. Should pump fail to stop, turn switch off and see the trouble shooting guide.

For portable use we recommend the pump be mounted on a base (i.e. 3/4” x 8” x 10” board or plywood), add a length of cable with alligator clips for battery connection or plug the 1 15V ac and 230V ac Models into a G.F.I. protected electrical outlet.

INSTALLATION

• STEP 1 Remove shipping plugs from Quad pump ports. Some water from factory testing may spill out.
• STEP 2 Install inlet A and discharge B port connectors. Firmly push slide clips C forward to lock port connectors in place.
• STEP 3 Slide rubber mounts D fully into 4 mounting tracks.
• STEP 4 Mount pump vertically, with pump head down or horizontally in an accessible location. If mounting vertically, motor up, attach motor mounts first, then pump head mounts while supporting weight of pump.
• STEP 5 Use 3/4” or 5/8” I.D. flexible hose (preferably braided or reinforced). Use hose clamps on the slip-on barb hose connectors.
• STEP 6 Install a 40 mesh in line strainer in accessible location between tank and pump inlet.

D.C. WIRING

• STEP 1 Use 14 gauge stranded wire to 20’, 12 gauge to 50’, from power source.
• STEP 2 Use a 15 amp rated on-off switch on the (+) positive (red) motor lead.
• STEP 3 Install fuse protection in the positive lead. 12V use 15 amp fuse, 24V use 7 amp fuse, 32V use 5 amp fuse.

NOTE: The 115 Volt model may be plugged directly into a 115V a.c. electrical outlet. A G.F.I. (ground fault interruption) outlet and switched circuit is required near water.

TROUBLESHOOTING

WARNING: before servicing pump, turn off pump and drain water from system!!

FAILURE TO PRIME – Motor operates, but no pump discharge

• Restricted intake or discharge line
• Air leak in intake line
• Debris in pump
• Punctured pump diaphragm (pump leaks)
• Crack in pump housing

MOTOR FALLS TO TURN ON

• Loose wiring connection
• Pump circuit has no power
• Blown fuse
• Pressure switch failure
• Defective motor
• Open thermal protector

PULSATING FLOW – Pump cycles on and off

• Restricted pump delivery. Check discharge lines, fittings and valves for clogging or under sizing.

PUMP FALLS TO TURN OFF AFTER ALL FIXTURES ARE CLOSED

• Empty water tank
• Insufficient voltage to pump (low battery)
• Punctured pump diaphragm (pump leaks)
• Discharge line leak
• Defective pressure switch

LOW FLOW AND PRESSURE

• Air leak at pump intake
• Accumulation of debris inside pump and plumbing
• Worn pump bearing (excessive noise)
• Punctured pump diaphragm (pump leaks)
• Defective motor

Quite often when a pump is worn or defective the one failed component has overburdened others. To avoid frequent aggravating repairs, Flojet offers service kit assemblies making repairs as quick and easy as possible.

DISASSEMBLE

PRESSURE SWITCH

1. Remove switch (9). Disconnect switch wires.

UPPER HOUSING

2. Loosen but do not remove four pump head screws and carefully remove upper housing assembly (1)
3. Inspect check valve (2) for debris
4. Reassemble new upper housing (1)

CHECK VALVE ASSEMBLY

FOLLOW STEP 2

1. Replace check valve (2)
2. Reassemble upper housing (1)

LOWER HOUSING, DIAPHRAGM, MOTOR

Follow step 2, then slide rubber foot from mounting track.

3. Rotate lower housing (4) so mounting notch opening on lower housing exposes set screw which holds bearing housing to shaft.
4. Loosen this set screw by inserting wrench 1/8” Allen wrench into mounting notch opening. Then, slide lower housing (4) off motor shaft.

DIAPHRAGM CONT’D

1. Loosen four cam piston screws with Phillips head screw driver and pull apart cam from inner pistons. (Pistons should always be replaced when a new diaphragm is installed.)

MOTOR CONT’D

1. REPLACE MOTOR

REASSEMBLE

MOTOR

1. Reassemble lower housing assembly (4) to motor. (Follow steps 4 to 10.)

DIAPHRAGM

2. Lower housing is assembled with:

• Flat side of diaphragm and outer pistons facing motor
• Hex stem of inner pistons must be aligned into hex holes in outer pistons (4).
• Outer pistons must be aligned with alignment slots on cam assembly making sum screw holes align in cam assembly, otherwise diaphragm will leak.

3. Tighten cam piston screws partially, center piston in diaphragm, then tighten screws securely (18 in. lbs. torque)

LOWER HOUSING

4. Reassemble lower housing assembly (4) to motor.
5. Retighten set screw securely. Set screw head must be positioned facing motor covering seam (indentation). (Positioning of this screw is critical to avoid misalignment and subsequent diaphragm damage.)

UPPER HOUSING, CHECK VALVE

6. Reassemble upper housing (1)
7. Properly seat O-Ring in check valve assembly (2) and check if few rules and screen a. in place on upper housing (1)
8. Install check valve (2) into upper housing (1) and push in.
9. Assemble on to lower housing (4), align 4 screws on to motor by rotating lower housing (4) if necessary to align feet
10. Tighten screws evenly to 30 in. lbs. torque.

PRESSURE SWITCH

1. Place switch against front of pump (9), insert screws and take care not to cross thread or strip out threads in housing.
2. Reconnect wires.

Frequently Asked Questions

is this pump wired for direct or 115V plug in?****

wired direct from on-off switch,(12V)

good day, please confirm if include port 3/4 to 90 degrees****

The pump comes with only a Straight 3/4 Fitting. you would need to order the Elbow by itself P/N 20381-010.

Is the 24 pump 4.5 gpm?****

Yes or more depending upon the size of the pipe input.

Will the 32v model run off of three 12v batteries/producing 36volts?****

For as long you wire the batteries in series, yes it will .

is this pump Variable speed?****

Only by using a variable rheostat but you really can’t get it to work below 19 volts.

Does this have a pressure switch and is it powerful enough to get through 3 filters?****

You should be using a pressure tank with it; it will shut off once it reaches about 40 psi. It is possible to increase the pressure by removing the outer cover at the wiring end and VERY carefully turning the screw in a 1/4 turn. I’ve had mine hooked up to 3 of the larger filters forever. A rope then paper then carbon filter. Without any problem. Remember if you increase pressure it decreases life of the pump.

I’ve tried ordering this pump in a 24 volt version 3 times now. Every time I get a 12 volt pump instead. Any suggestions?****

Here is the Model Number you need in 24VDC listed below.
-04325343A MPU 24V 4.3GPM

Product ships with in line Filter Screen Assembly?****

I think it arrived without the in-line filter assembly.

what is the warranty period****

We contacted the product technical specialist; David Mendoza and he was very helpful with our problem. He can be reached at
david.mendoza@xyleminc.com.

Picture doesn’t match description, is this a 40psi or 35psi?****

a like to buy 40psi not 35psi.

When it says no pressure nozzle, what does that mean? I may have ordered the wrong pump****

The pump does produce PSI. When you say no nozzle, do you mean a hand held nozzle? if so, you are correct. Does not come with. What you see in the picture is what you get.

Is this pump variable speed?****

I bought it to my boat, and it’s working very well! The speed is good! I mean, I’m satisfied with this pump.

Is it normal for this pump to be shipped with water in it?****

Yes, all of our pumps are tested before they leave the factory so there may be some residual water left in the pump.

Which one is it? Title says 4.5gpm, description says 3.3gpm!****

Depends on pipe sizes and amp input.

Does it include the strainer as pictured?****

Yes you can also get this pump without the strainer.
