SERVICE AND OPERATING MANUAL
A WARREN RUPP PUMP BRAND
PLEASE NOTE!
The photos shown in this manual are for general instruction only. Your specific
model may not be shown. Always refer to the parts list and exploded view drawing
for your specific model when installing, disassembling or servicing your pump.
PRINCIPLE OF OPERATION
All Marathon pumps, including this Spill Containment model, operate on the
same basic principle. They are powered by compressed air which alternately
pressurizes the inner sides of the two diaphragm chambers while simultaneously
exhausting the opposite inner chambers causing the diaphragms, which are
connected by a shaft, to move endwise. Since air pressure is applied over the entire
surface of the diaphragm which is forcing liquid to be discharged by its other side,
the diaphragm is operating under a balanced condition during the discharge stroke.
This allows the unit to be operated at discharge heads over 200 feet (61 meters) of
water head.
Alternate pressurizing and exhausting of the diaphragm chamber is performed
by an externally mounted, pilot-operated, four way, spool type air distribution valve.
When the spool is at one end of the valve body, inlet air pressure is connected to one
diaphragm chamber and the other diaphragm chamber is connected to the exhaust.
When the spool is removed to the opposite end of the valve body, the porting of
chambers is reversed. The air distribution valve spool is moved from one end position
to the other in the valve body by means of an internal pilot valve which alternately
pressurizes the ends of the air distribution valve spool while simultaneously
exhausting the other ends. The pilot valve is positively shifted at each end of the
diaphragm stroke by the diaphragm plate’s coming in contact with the end of the pilot
valve spool and pushing it into position for shifting of the air distribution valve. The
chambers are manifolded together with a suction and discharge check valve for each
chamber to maintain flow in one direction through the pump.
This Marathon pump differs from other Marathons only in that it utilizes four
diaphragms instead of two, the two rod-connected diaphragms being the driver
diaphragms, and the other two (outermost) diaphragms being the actual pumping
diaphragms. Each driver diaphragm (of Neoprene or other elastomer), and the
pumping diaphragm (of Teflon), are separated by a chamber filled with liquid which
transmits the reciprocating motion of the driver diaphragm to the pumping diaphragm.
The Teflon pumping diaphragms, in turn, create the alternating suction and discharge
action to each outer diaphragm chamber. The outer diaphragms are the only ones in
contact with the liquid being pumped.
INSTALLATION PROCEDURES
Position the pump as close as possible to the source of the liquid to be pumped.
Avoid long or undersize suction lines and use the minimum number of fittings. High
vacuums reduce flow rate capability and shorten driver diaphragm service life.
Suction head is not recommended except where NPSH might so dictate.
For permanent installations involving rigid piping, install short flexible sections
of hose between the pump and piping. This reduces strains and permits easier
removal of the pump for service when required. At time of installation, inspect all
external gasketed fasteners for looseness caused by gasket creep. Tighten
loose fittings securely to prevent leakage.
FILLING OF DRIVER CHAMBERS WITH LIQUID
THE DRIVER CHAMBERS WILL BE FILLED WITH WATER AT THE FACTORY.
If you prefer to substitute another liquid, to prevent system contamination consult
the factory first to determine compatibility of the substitute with pump construction.
Follow the steps listed below to replace the liquid in the pump after disassembly
or liquid loss:
Model MP07D
Design Level 3
IMPORTANT
Read these instructions completely,
before installation and start-up. It is
the responsibility of the purchaser to
retain this manual for reference.
Failure to comply with the
recommendations stated in this
manual will damage the pump, and
void factory warranty.
WARNING
Take action to prevent static sparking.
Fire or explosion can result, especially
when handling flammable liquids. The
pump, piping, valves, containers or
other miscellaneous equipment must
be grounded.
BEFORE OPERATION
Before pump operation, all external
gasketed fasteners must be inspected
for looseness caused by gasket creep
after leaving the factory. Retorque
loose fasteners to insure against
leakage. Follow recommended
torques where called out. (A card is
attached to each new pump stating
this fact.)
CAUTION
This pump should not be applied in
pumping applications where the
driver liquid coming in contact with
the pumped liquid would create a
hazardous condition. This could
happen in case of a Teflon pumping
diaghragm failure since this
diaphragm normally separates the two
liquids. Also note that care must be
taken to guard against the operation
of this unit if it has been subjected to
freezing temperatures. Because of the
driver liquid used, possible
diaphragm failure may result.

1. Filling is accomplished through the pipe plugs at the top of the liquid driver
chamber. Remove the plugs.
2. Remove the entire discharge manifold assembly exposing the ports in the
outer diaphragm chambers.
3. With 5-10 PSI of air pressure at inlet, lock the spool to one side with locking pin
(safety clip; item 61) (Fig. 1). You will fill the opposite side diaphragm from the
“Locked Area.”
4. Fill with 2500MI. (84.53 fl. oz.) by volume with the driver liquid. It is imperative
that the driver liquid chambers be filled with the correct amount of driver liquid as too
little or too much will cause premature diaphragm failure and erratic pumping.
5. After filling with the proper amount of liquid, if the liquid does not come to the
top of the fill hole, pressure should be applied to the Teflon diaphragm with a blunt
tool through the material flow port in the outer chamber until it does come to the top.
Relieving air pressure will relax diaphragms at this point.
6. When the driver fluid rises to the top of the fill plug hole, screw the boss plug,
with o-ring installed, into the chamber. (Do not overtighten.) (Fig. 2) Remember to
keep pressure on the Teflon diaphragm until the boss plug is tight to prevent air from
drawing back into the chamber.
7. Filling the opposite side is accomplished in the same manner as described.
AIR SUPPLY
Do not connect the unit to an air supply in excess of 125 PSI (8.61 bars). Install
a shutoff valve in the air supply line to permit removal of the unit for servicing. When
connecting an air supply of rigid piping, mount a section of flexible line to the pump
to eliminate piping strain. In permanent installations, an air line filter is
recommended.
A NOTE ABOUT AIR VALVE LUBRICATION
The Marathon pump’s pilot valve and main air valve assemblies are designed to
operate WITHOUT lubrication. This is the preferred mode of operation. There may
be instances of personal preference, or poor quality air supplies when lubrication of
the compressed air supply is required. The pump air system will operate with
properly lubricated compressed air supplies. Proper lubrication of the compressed
air supply would entail the use of an air line lubricator (available from Marathon) set
to deliver one drop of 10 wt., non-detergent oil for every 20 SCFM of air the pump
consumed at its point of operation. Consult the pump’s published Performance
Curve to determine this.
It is important to remember to inspect the sleeve and spool set routinely. It
should move back and forth freely. This is most important when the air supply is
lubricated. If a lubricator is used, oil accumulation will, over time, collect any debris
from the compressed air. This can prevent the pump from operating properly.
Water in the compressed air supply can create problems such as icing or
freezing of the exhaust air causing the pump to cycle erratically, or stop operating.
This can be addressed by using a point of use air dryer (available from Marathon) to
supplement a plant’s air drying equipment. This device will remove excess water
from the compressed air supply and alleviate the icing or freezing problem.
EXTERNALLY SERVICEABLE AIR
DISTRIBUTION SYSTEM
Please refer to the exploded view drawing and parts list in the Service Manual
supplied with your pump. If you need replacement or additional copies, contact your
local Marathon Distributor, or the Marathon factory Literature Department at the number
shown below. To receive the correct manual, you must specify the MODEL and TYPE
information found on the name plate of the pump.
MODELS WITH 1" SUCTION/DISCHARGE OR LARGER,
AND METAL CENTER SECTIONS:
The main air valve sleeve and spool set is located in the valve body mounted on the
pump with four hex head capscrews. The valve body assembly is removed from the
pump by removing these four hex head capscrews.
With the valve body assembly off the pump, access to the sleeve and spool set is
made by removing four hex head capscrews (each end) on the end caps of the valve
body assembly. With the end caps removed, slide the spool back and forth in the sleeve.
The spool is closely sized to the sleeve and must move freely to allow for proper pump
operation. An accumulation of oil, dirt or other contaminants from the pump’s air supply,
If the pump has been subjected to
CAUTION
freezing temperatures, do not operate
until the unit is completely thawed.
Fig. 1 Safety clip.
Fig. 2 Tighten the boss plug.
DANGER
Before doing any maintenance on
the pump, be certain all pressure is
completely vented from the pump,
suction, discharge, piping, and all
other openings and connections.
Be certain the air supply is locked
out or made non-operational, so that
it cannot be started while work
is being done on the pump. Be
certain that approved eye protection
and protective clothing are worn
at all times in the vicinity of the
pump. Failure to follow these
recommendations may result in
serious injury or death.
Model MP07D Design Level 3 Type 4 Page 2 520-134-000 3/03
or from a failed diaphragm, may prevent the spool from moving freely. This can cause
the spool to stick in a position that prevents the pump from operating. If this is the case,
the sleeve and spool set should be removed from the valve body for cleaning and further
inspection.
Remove the spool from the sleeve. Using an arbor press or bench vise (with an
improvised mandrel), press the sleeve from the valve body. Take care not to damage
the sleeve. At this point, inspect the o-rings on the sleeve for nicks, tears or abrasions.
Damage of this sort could happen during assembly or servicing. A sheared or cut
o-ring can allow the pump’s compressed air supply to leak or bypass within the air valve
assembly, causing the pump to leak compressed air from the pump air exhaust or not
cycle properly. This is most noticeable at pump dead head or high discharge pressure
conditions. Replace any of these o-rings as required or set up a routine, preventive
maintenance schedule to do so on a regular basis. This practice should include
cleaning the spool and sleeve components with a safety solvent or equivalent,
inspecting for signs of wear or damage, and replacing worn components.
To re-install the sleeve and spool set, lightly lubricate the o-rings on the sleeve with
an o-ring assembly lubricant or lightweight oil (such as 10 wt. air line lubricant). Press
the set into the valve body easily, without shearing the o-rings. Re-install one end cap,
gasket and bumper on the valve body. Using the arbor press or bench vise that was
used in disassembly, press the sleeve back into the valve body. You may have to clean
the surfaces of the valve body where the end caps mount. Material may remain from
the old gasket. Old material not cleaned from this area may cause air leakage after
reassembly. Take care that the bumper stays in place allowing the sleeve to press in
all the way. Re-install the spool, the opposite end cap, gasket and bumper on the valve
body. After inspecting and cleaning the gasket surfaces on the valve body and
intermediate, re-install the valve body on the pump using new gaskets. Tighten the four
hex head capscrews evenly and in an alternating cross pattern.
OPERATION
Your Marathon pump has been tested prior to shipment and is ready for use as
received. It is completely self-priming and no initial filling with fluid is required.
If the unit is to be totally submerged, the air exhaust must be piped above the
liquid level to prevent the liquid and foreign material from entering the air
distribution valve mechanism.
Open the inlet air valve at least one turn to allow sufficient cycling rate for the
pump to prime (30 to 60 cycles per minute). After pumping starts, adjust the inlet air
valve for the desired pumping capacity. When further opening of the inlet air valve
increases cycling rate without increasing the flow rate, the pump is being starved of
liquid due to suction limitations. Further opening of the air inlet valve will waste
compressed air. Set the inlet air valve for lowest cycling rate that does not decrease
flow rate for most efficient operation.
FREEZING OR ICING OF EXHAUST
Icing of the air exhaust can occur under certain conditions of temperature and
humidity on compressed air power equipment. When pump performance suffers
because of icing, use of an air dryer will solve the problem. Icing is more likely to
occur at high discharge pressures.
AIR EXHAUST
Marathon pumps can be submerged if the materials of construction are
compatible with the liquid and the exhaust is piped above the liquid level. (See
OPERATION, above.) Piping used for the exhaust should not be smaller than 1"
pipe size. Reduced pipe size can restrict the exhausted air and reduce pump
performance.
CHECK VALVE SERVICING:
Need for inspection or service is usually indicated by poor priming, unstable
cycling, reduced performance or the pump’s cycling but not pumping.
DIAPHRAGM SERVICING:
Driver Diaphragms
Drain the driver diaphragm chamber by removing the boss plug on the
underside of the driver chamber. Remove eight bolts securing the two manifolds to
the chambers. Remove eight bolts securing the diaphragm chamber. This permits
inspection of the Teflon diaphragm and the driver diaphragm. Loosen the plate
In the event of diaphragm rupture,
CAUTION
pumped material may enter the air end
of the pump, and be discharged into
the atmosphere. If pumping a product
which is hazardous or toxic, the air
exhaust must be piped to an
appropriate area for safe disposition.
CAUTION
Do not use a wrench on the
diaphragm rod. Flaws on the surface
may damage the bearings and seals.
520-134-000 3/03 Model MP07D Design Level 3 Page 3
which secures the diaphragm and plate to the rod by keeping the diaphragm
engaged with the inner diaphragm chamber by inserting two or three capscrews
through the bolt holes so that the diaphragm cannot rotate when loosening. The
diaphragm plates, diaphragm and bumper will now come off the assembly. Repeat
all actions if the other diaphragm needs to be inspected or replaced.
Procedures for reassembling the diaphragms are the reverse of the above. The
diaphragms must be installed with their natural bulge to the outside, toward the
outer diaphragm plate. Install the inner plate with the flat face against the
diaphragm.
After all components are in position in a vise and hand tight, tighten with a
wrench to approximately 40 ft. lbs. (5.53 kilograms/meters) torque. After both
diaphragm assemblies have been assembled, thread one assembly into the shaft
(hold the shaft near the middle in a vise with soft jaws, to protect the finish). Install
this subassembly into the pump and secure by placing the outer chamber on the
end with the diaphragm. This holds the assembly in place while the opposite side is
installed. Torque the last diaphragm assembly to 30 ft. lbs. (4.147 kilograms/meters).
This final torquing will lock the diaphragm assemblies together. Place the remaining
outer chamber on the open end and loosely tighten the bolts. Replace the manifold
assemblies to square the flanges before final tightening of the remaining bolts,
alternating for progressive tightening, the eight capscrews that secure outer
chamber to inner chamber.
Make sure the o-ring between the Teflon driver chamber and Teflon driver
diaphragm is in place before final torquing of the eight capscrews that hold the
chambers together.
MAINTENANCE AFTER USE
When the pump is used for materials that tend to settle out or transform from
liquid to solid form, care must be taken after each use or during idle time to remove
them and flush the pump as required to prevent damage.
In freezing temperatures the pump must be completely drained when idle. This
model must be tilted to allow the liquid from the chambers to run out of the discharge
port.
MAINTENANCE NOTE
A preventative maintenance procedure should be established to check the
Teflon diaphragms for breakage. Even though this part was proven to be good for
millions of cycles, each application may present its own problems.
The choice of the Teflon unit would tend to show that the material being handled
would not be compatible with the standard Neoprene or other rubber. If a Teflon
diaphragm were to break, the unit would continue pumping via the driver diaphragm.
In a standard Marathon pump, a ruptured diaphragm would show up as air bubbles
in media being pumped or pumped material being blown out the exhaust muffler.
These events would not occur in the Teflon unit until the material in the driver
diaphragm had been attacked and destroyed. If it were to reach that point, the pump
as a whole would stand a chance of being lost instead of just a diaphragm.
SERVICE INSTRUCTIONS:TROUBLE SHOOTING
1. Pump will not cycle
A. Check to make sure the unit has enough pressure to operate and that the air inlet
valve is open.
B. Check the discharge line to insure that the discharge line is neither closed nor
blocked.
C. If the spool in the air distribution valve is not shifting, check the main spool. It must
slide freely.
D. Excessive air leakage in the pump can prevent cycling. This condition will be
evident. Air leakage into the discharge line indicates a ruptured diaphragm. Air
leakage from the exhaust port indicates leakage in the air distribution valve. See
further service instructions.
E. Blockage in the liquid chamber can impede movement of diaphragm.
F. Plugged or dirty exhaust muffler.
2. Pump cycles but will not pump
A. Suction side of pump pulling in air. Check the suction line for air leaks and be
sure that the end of the suction line is submerged. Check flange bolting. Check
valve flanges and manifold to chamber flange joints.
IMPORTANT
This pump is pressurized internally
with air pressure during operation.
Always make certain that all bolting is
in good condition and that all of the
correct bolting is reinstalled during
assembly.
Fig. 3 Pilot valve removal
Fig. 4 Pilot valve spool and o-rings
CAUTION
If a diaphragm fails, the pumped
product or fumes can enter the air side
of the pump. This side is exhausted
through the exhaust port (muffler).
When the product is a hazardous or
toxic material, the exhaust should be
piped to an appropriate area for safe
disposition.
When the product source is at a
higher level than the pump (flooded
suction), the exhaust should be piped
to a higher level than the product to
prevent spills caused by siphoning.
Model MP07D Design Level 3 Type 4 Page 4 520-134-000 3/03
B. Make certain the suction line or strainer is not plugged. Restriction at the suction
is indicated by a high vacuum reading when a vacuum gauge is installed in the
suction line.
C. Check valves may not be seating properly. To check, remove the suction line and
cover the suction port with your hand. If the unit does not pull a good suction
(vacuum), the check valves should be inspected for proper seating.
D. Static suction lift may be too high. Priming can be improved by elevating the
suction and discharge lines higher than the check valves and pouring liquid into the
unit through the suction inlet. When priming at high suction lifts or with long suction
lines operate the pump at maximum cycle rate.
E. Check driver fluid level.
3. Low performance
A. Capacity is reduced as the discharge pressure increases, as indicated on the
performance curve. Performance capability varies with available inlet air supply.
Check air pressure at the pump inlet when the pump is operating to make certain
that adequate air supply is maintained. Low flow rate as discharge pressure
increases can also be a sign of too little or no driver liquid in the driver chamber.
B. Check the vacuum at the pump suction. Capacity is reduced as vacuum
increases. Reduced flow rate due to starved suction will be evident when the cycle
rate can be varied without change in capacity. This condition will be more prevalent
when pumping viscous liquids. When pumping thick, heavy materials the suction
line must be kept as large in diameter and as short as possible, to keep suction loss
minimal.
C. Low flow rate and slow cycling rate indicate restricted flow through the discharge
line. Low flow rate and fast cycling rate indicate restriction in the suction line or air
leakage into suction.
D. Unstable cycling indicates improper check valve seating on one chamber. This
condition is confirmed when unstable cycling repeats consistently on alternate
exhausts. Cycling that is not consistently unstable may indicate partial exhaust
restriction due to freezing and thawing of exhaust air. Using the Warren Rupp
extractor/ dryer should solve this problem.
E. Check driver fluid level.
WARRANTY
This unit is guaranteed for a period of five years against defective material and
workmanship.
Before maintenance or repair, shut off
CAUTION
the compressed air line, bleed the
pressure, and disconnect the air line
from the pump. The discharge line
may be pressurized and must be bled
of its pressure. When the pump is
used for toxic or aggressive fluids, it
should be flushed clean prior to
disassembly.
CAUTION
Do not use a wrench on the
diaphragm rod. Flaws on the surface
may damage bearings and seals.
NOTE
See ‘‘Filling of Driver Chamber with
Liquid’’ for the correct procedure to
recharge the pump for operation.
NOTE
When electronic leak detector is used
with this model pump, the probes
must be fitted into special boss plugs,
to replace item 56, bottom. Order one
kit 475-098-000 for each pump.
