Performance Specifications P-98-220E pg.2
Pump Performance Is Dependent On Cycle Rate & Installation Head:
Volume is expressed in GPM (gallons per minute) and LPM (liters per minute)
Cycle Rate is the rpm of the motor divided by the ratio of the reducer. i.e. 1725 rpm / 31= 56
Head conditions are determined by the height, length and size of the installation plumbing to
and from the pump and the viscosity of the liquid.
General Specifications:
Static Head: Suction 18 ft / 5.48m Discharge 18 ft / 5.48m (1.5" Hose or Pipe)
Dry Suction Head: 15 ft / 4.57m (1.5"ID Pipe or Hose)
Continuous Duty Discharge Heads: Should be Limited to 10 ft. / 3m
Performance: 18 GPM / 68.4 LPM at 4 ft Suction Lift and 0 Discharge at
56 Cycles per Min. w/ 1.5" Pipe
Volume Charts:
Use these performance charts as a guide to determine the volume to expect from the
pump you are installing. Volumes are based on the suction height, discharge height and
speedofthe pump pumping water through1.5”pipe.Actual performance will varybasedon
lengthof the plumbingand the viscosity ofthe liquid beingpumped.

Important Plumbing Do & Don’ts
DONOTSHUTOFFDISCHARGEWHEN
THE PUMP IS RUNNING - Do not place the
pump in a situation were the discharge line
will be closed while the pump is running.
BECAUSE the Edson pump is a positive
displacement pump and it will continue to try
topump liquid through aclosed line. The pressure
created will cause damage to the pump.
DISCHARGEFITTINGS,PIPEANDHOSE
SHOULDALL BE THE SAME SIZEANDSHOULD
NEVERBESMALLERTHANTHEINLET
BECAUSE a smaller discharge line increases
work for the pump and increases the possibility
ofclogging.
DONOTINSTALLTHEPLUMBINGSOAIRIS
TRAPPED - Install pump and plumbing so any air
introducedinto the plumbing cannot be trappedbut
flow naturally through liquid and out of the system.
BECAUSEtrapped air cancompletely
restrict the flow or at the least will require
morework from the pumpresulting in early
diaphragmfailure.
SHOULDNOTINSTALL PUMPWITHPOSITIVE
HEADONTHEINLET-Understandard operating
guidelines the pump should be above the liquid it is
beingusedto transfer.
BECAUSE the Edson pump is a suction pump and
ituses flapper type checkvalves.Located below
the liquid the pump will start a siphon that may
beunsafeorundesirable.Understandardoperating
conditions a positive suction head will increase the
back pressure that will cause early wear and
possibledamage.
Self Priming:
The Compact Pump will develop a dry start vacuum of 13 to 15 inches of mercury, equal to a
height of approximately 17'.After prime vacuum pressurewill increase to 20”hg or more. This
featuredependson

Running The Pump Dry:
TheEdson Compact Pump willrundry indefinitely without damage.
Pumping Liquids with Suspended Solids:
KEEPSOLIDS IN SUSPENSION - When the pump
is used to pump solid matter such as sludge at
the bottom of a tank or to dredge out a section of a
lagoonmakesure the solids haveenoughliquid
mixed in to allow it to flow. Raking or stirring while
the pump is pumping will keep solids in
suspension.Ruleof thumb in pumpingviscous
liquids or combinations of liquids with solids, "If It
WillNot FlowThroughALineUnderGravity,The
Pump Will Most Likely Not Pump It." Fig.11
FLAPPER CHECK VALVESAND SOLIDS -
Solid matter can get trapped under the check
valves, especially when the pump is used in an
intermittent application such as sewage or sump
pump out. This will prevent self priming at the next
use. Flushing with water will generally clear out the
solidmatter.Installing secondary clear flapper
check valves right at the inlet and discharge will
improvethe dry suction start performanceofthe
pumpandmake clearing the valves easy. Order
EdsonClearCheckValves269CL-150for11/2".
Fig.12
PUMPINGATTHE PROPER SPEED - When
pumping liquid with solids the speed may be to
slow to keep some solids and the liquid combined.
The solids will stop moving and begin to clog the
line. Pumping at a faster rate or decreasing the
hose size to increase velocity may be the solution.
CheckWith Edson Customer Service.
USINGA STRAINER ON THE INLET- Likeany
vacuum used to pick up solid matter, if the solid
material is to large it will block the inlet or get
stuck in the suction line. Also a suction hose can
suck up on a flat surface cutting off all flow. Using
an Edson stainer will prevent these conditions.

Pump Speed:What speed is best depends on the application, what type of liquid is being pumped and the
head conditions. The following guidelines apply for this pump.
Maximum Cycle Rate is 60 RPM on the output shaft of the gear reducer.
The higher the viscosity the slower the pump. Viscous liquids need time to respond to
pumpingpressures.
11/4”ID plumbing requires pumpspeedsunder 45 RPM.
Smallsuction lines under1” ID requirespeeds under 20RPM.
Thehigher the backpressure the slower thepump RPM.
Maintenance
Diaphragm:Edson Pumps use ElastomerDiaphragmand Flapper Valves.These partswear and arein
need of periodic replacement. The ability to easily and quickly replace these inexpensive parts in
the filed is one of the major advantages of these pumps. Edson has packaged these parts as
Spares Kits. See the parts list for the order #s.
Changethediaphragmas required. Fig. 22
Visual inspection on a regular bases is recommended.
Continuous duty applications should be inspected daily until a life pattern is established.
Look for leaks, cracks or splits on the surface of the diaphragm.
Life expectancy is directly related to head conditions, run time and diaphragm material. The
higherthe suction anddischarge pressures theshorter the life.
Warning
Lock Out Electrical Service or Unplug the Pump Electrical
Line, Before Performing Any Service.
Failure to Do So Will Result In Bodily Injury
ValveAssemblies & The Valve Seats:Together with the raising and lowering of the diaphragm, the sealing
oftheflappervalvesare what make the diaphragm pumpwork.Ifthevalvesarenot sealing properly,
the pump will not be performing to full potential or may not be pumping at all. Thevalves tend to last
longerthan the diaphragm. When youchangethe diaphragm inspect thevalvesfor cracks and
delaminationandthevalve seats for pitting and anybuildupthatwillprevent the valve rubber from
sealingeffectively.Testingthepump is the bestwayto evaluate performance.
Changethevalveassemblies as required. Fig. 23
Inspectionand testing on a regularbases is recommended.For continuous dutyapplication,
inspect daily until a life pattern is established.
See Pump PerformanceTests (page 8) for how to test the pump.
Step 1. Unbolt the Inlet and the
Discharge Chamber.
Step 2. Inspect Valve Seats.
Surfaces should be smooth,
flat and free of foreign matter.
Step 3. Resurface, if neces-
sary. Use a flat belt sander or
medium grade emery cloth
wrapped on a flat piece of
wood. It is important that the
valve seat area remains flat.
Step 4. Install New Valves.
Insure Valve Weight Screws
are Tight and Valves are
Oriented Properly.

Volume Test -Tests overall performance of the pump installation.
1.Use a container with a known capacity of at least 2 gallons.
2.Empty the container using the suction side of the pump or fill it from the discharge.
When using the fill test make sure the pump is fully primed before filling the container.
3.Use a watch to record the time it takes. Repeat the test at least twice.
4.Establish GPM rate. Example 1: It took 7 seconds to fill a 2 gallon container. The
GPM rate is 17 Gallons Per Minute.(60 seconds divided by 7 seconds times 2 gal.)
Example 2: It took 35 seconds to empty a 2 gallon container. The GPM rate is 3.4
Gallons Per Minute.(60 seconds divided by 35 seconds times 2 gal.)
5.Record the cycle speed of the pump. Know the head conditions of your test and
comparethe results of yourtestwith the volumeofthe appropriate Volume Chart
on page 2. Every installation is different so use the charts as a guideline.
6.Example 1: The “fill test” at 17 GPM. The diaphragm is going up and down at 56
cycles per minute. The pump is approximately 6 ft. above the liquid. I disconnected the
installation discharge line and replaced it with a 3 ft. length of 1.5” hose so I could do
the fill test. Using the 56 cycle per minute Volume Chart from page 2, I know that at
a suction height of 5 ft. and a discharge height of between 0 and 5 ft. I should get
approximately17 GPM. The installationis performing within theguide lines.
6.Example 2: The “empty test” at 3.4 GPM. The diaphragm is going up and down at 30
cycles per minute. The pump was approximately 5 ft. above the 2 gal. container and
the discharge line goes up 4 ft. Using the 30 cycle per minute Volume Chart from page
2, I know that at a suction height of 5 ft. and a discharge height of between 0 and 5 ft. I
shouldget approximately 5.5 GPM.Theinstallation is performing belowtheguide-
line. For help in determining why, turn toTrouble Shooting page 9.
Manual Test - Testing the pump valves and valve seats without the use of a gauge.
1.Removeallfittings from theinletand discharge of thepump.
2.Turn onthepump.
3.Putyourhand over the inlet.Ifthe discharge valve isworkingproperly, you should feela
verystrong pulsing suction. Thepulsingcoincides with the raisingandloweringofthe
diaphragm. If you do not feel any suction, do the same thing again and listen for
airbeing sucked in aroundthediaphragm. If you hearairmovement, inspect for loose
boltsorwarndiaphragm.If you hear no air movement,removethedischargechamber
andinspectthevalve assembly and valve seat.Cleanorreplacethevalve and clean or
resurfacethevalveseatasappropriate.
4.Pressyourhand over the discharge.Ifthe inlet valve issealingproperly, thepressureof
the pump down stroke should push your hand away. If it does not and the air is forced
outtheinlet remove the inletchamberand inspect the valveassemblyandvalve seat.
Cleanorreplacethevalve and clean or resurface the valve seatasappropriate.See
Maintenance/ValveAssembliespg.7
Vacuum Gauge Test - Tests the performance of the discharge valve and valve seat.
1.Attacha 5’ lengthof non-collapsing hoseor pipe witha vacuum gaugeinstalled
to the inlet of the pump. Make sure the line is completely sealed and air tight.
2.Turn on the pump and let it run till the gauge stabilizes. Record the reading.
3.Turnoffthe pump and watch thegauge.
4.Ifthe discharge is workingproperly the gaugeshould build and holdat 13” to15”hg.
Do not be concerned if the vacuum pressure slowly returns to 0 within a minute or so.
5.If you do not get any vacuum reading or if the gauge does not get to 13” hg and
drops off to 0 as soon as the pump stops, do the same thing again. Listen for air
beingsucked in around the diaphragm.Ifyou hear air movement,inspectfor loose

1.Attach a 5’ length of non-collapsing hose or pipe with a 0 to 15 psi gauge installed
to the outlet of the pump. Make sure the line is completely sealed and air tight.
2.Turn on the pump and let it run till the gauge stabilizes. Record the reading.
3.If the suction valve is working properly the gage should build and pulse at 7 to 8 psi.
and when the pump is stopped the pressure may hold or slowly returns to 0.
4.If you do not get any pressure reading or if the gauge does not get to 4 psi and drops
off to 0 as soon as the pump stops, clean or replace the suction valve and clean or
resurfacethevalveseat as appropriate. See Maintenance/ValveAssembliespg.7

Trouble Shooting
P-98-220E pg.9
5.Problem
Pumpbase and/or lines
keep filling with solids.
PossibleCauses
a. Line velocity is too slow to
keep the solids in suspen
sion.
b. The percent of solids is too
high.
Action
Speedingup the pumpwill help increasethe
velocity. Using a strainer can reduce the size and
percent of solids. Diluting the slurry by increasing
the amount of liquid or by increasing the agitation
ofthe mix may solvetheproblem.Review
PumpingLiquids with Suspended Solidspage5
4.Problem
Diaphragmiswearing
outmuch earlier than
expected.
PossibleCauses
a. Liquid being pumpedis not
compatiblediaphragm
material.
b. Discharge and/or suction
back pressure too high.
Action
Consulta chemical resistancechart,review the
Installation guide lines pages 2 to 5. Call Edson
CustomerService.
3.Problem
Motoris running but
reducerisnot moving.
PossibleCause
a. Reducer Coupling hascome
lose on the motor shaft.
Action
Removethemotorand reposition and secure the
coupling to the motor shaft. See parts diagram
forpositioning instructions.
2.Problem
Motor is not coming on. PossibleCauses a. Electrical Supply or wiring
problem.
b. Motor worn out.
Action
Check electrical switch and/or circuit breaker. If
not familiar with electrical problems, call an
electrician. If circuit breaker is tripped for no
apparent reason or the motor is worn out
way too soon, check the pump and the line
for a blockage or restriction. Review the
Performance Specifications and installation
Guidelines pages 2 to 5.
1.Problem
Pumpis running, liquid
isnotmoving.
PossibleCauses
a. Suction line is blocked.
b. Suction line has air leak
betweenliquid and inlet ofthe
pump.
c. Dischargeand/orsuction
valvesarenotworking.
d. Diaphragm has aleak.
e. Discharge or suction line is
to high.
Action
If the cause is not obvious, isolate the source.
Disconnectthe inlet and dischargeplumbingfrom
thepump and perform theManualTest page 8.If
the cause is not in the pump check for a block or
an air leak in the suction line. Suction air leaks
can be cumulative and can be as simple as one
ortwofittings not being sealed properly.Review

Eccentric: Adisk called an eccentric is pressed onto the output shaft of the gear reducer. As it rotates
inside the bronze eccentric housing the diaphragm is raised and lowered. This assembly needs to
be greased with any good gear grease. Edson appliesMobil Grease HP Multiporpose
Premium Grease during the assembly of the pump. Failure to grease this part will result in early
wear.
