IMPELLER REPLACEMENT
The impeller must be replaced if it is worn out or has been
damaged by debris or by running the pump dry. Symptoms of a
defective impeller are low pumping pressure and low flow causing
overheating of the boat engine. Poor pump performance can also be
caused by slippage of V-belts, so belts should be checked for tightness.
To replace the impeller remove screws and cover cover. Pull
out the impeller with nose pliers or two screwdrivers. Be careful not
to dent the pumping chamber with these tools. When inserting new
impeller, line up key slot in impeller with the key in the shaft. Use oil
on shaft and avoid forcing the impeller onto the shaft.
The impeller should also be removed for storage periods to
prevent the blades from taking a permanent set.

SEAL REPLACEMENT (Continued from front)
If water drips from the weep hole of from the area where the
shaft exits the pump, the seal is defective and must be replaced. While
the Teflon(R)* barrier seal provides a first line of defense, prolonged
running of the pump with a leaky seal can destroy the ball bearings
resulting in catastrophic pump failure and engine shut-down.
For seal replacement, the pump must be removed from the
engine and disassembled in order to gain access to the seal area.
4/01
www.oberdorfer-pumps.com
Where mechanical seals are used, both components (stationary and rotating member) must be replaced at the same time.
Lip seals must be pushed out of their press-fitted position and
new seals pressed into place, using a sealant on the outside
of the lip seal housing.
Refer to exploded view drawings for seal location and
part numbers for ordering purposes.
Specifications are subject to change without notice.

SEAL REPLACEMENT
If water drips from the weep hole of from the area where the shaft
exits the pump, the seal is defective and must be replaced. While the
Teflon(R)* barrier seal provides a first line of defense, prolonged running of the pump with a leaky seal can destroy the ball bearings resulting in catastrophic pump failure and engine shut-down.
For seal replacement, the pump must be removed from the
engine and disassembled in order to gain access to the seal area.
3/01
www.oberdorfer-pumps.com
Where mechanical seals are used, both components (stationary and rotating member) must be replaced at the same time.
Lip seals must be pushed out of their press-fitted position and
new seals pressed into place, using a sealant on the outside
of the lip seal housing.
Refer to exploded view drawings for seal location and
part numbers for ordering purposes.
Specifications are subject to change without notification.

FEATURES
SUCTION LIFT
• Bronze Corrosion Resistant Castings
• Special Cast Bronze Gears
• Stainless Steel Shafts & Fasteners
• Formed Ring Seal Packing (Lip & Mechanical
Seals on Special Order)
• Heavy Duty Carbon Bearings (Self Lubricating)
• Positive Displacement Flow
DRIVE
Either direct drive with flexible coupling or pulley drive
can be used. Make sure both flexible coupling halves are
properly aligned. When using a pulley, do not overtighten the
belt. Also, to absorb belt side thrust at higher pressures and
larger size pumps, an external ball bearing support is recommended -- consult
factory.
LIQUIDS AND TEMPERATURE
Service life will be increased substantially if the liquid
pumped is clean and has some degree of lubricity. These
positive displacement pumps have tight tolerances. Fine
abrasives like sand, silt, or powders in suspension will accelerate pump wear and reduce throughput.
Liquids compatible with bronze and stainless steel can
be pumped providing proper seal has been specified (see
chemical compatibility or check factory). When possible,
flush the pump after each usage.
Temperature extremes are detrimental to service life
and should be avoided. Basic metals of construction allow a
temperature range of -40 to 400oF. Some lip and mechanical seal elastomers have a limit of 212oF. (see engineering
data or check factory). Allowing a liquid to freeze in the pump
can cause damage.
www.oberdorfer-pumps.com
MODEL N1000R
Close tolerances and the positive pumping action make the
rotary gear pump capable of lifting water on the suction side as
high as 20 feet. Though gear pumps are self priming, a foot valve
is recommended. If possible, wet the gears with liquid to be
pumped for the first dry start. Liquid retained in the system and
gear chambers serves to “wet” the pump on subsequent starts.

BY-PASS AND ROTATION
The pump by-pass is not intended to be a
metering or flow control device. Its main purpose is
to function as a pressure relief when the desired set
point is exceeded, overheating can occur within 5 10 minutes if the discharge line is completely shut
off for extended periods.
Reversing rotation reverses the “IN” and
“OUT” ports and the location of the by-pass ports
have to be reversed.
The by-pass valve is factory set at 50 p.s.i. To
increase the setpoint, turn the by-pass valve adjusting screw in a clockwise direction.

PERFORMANCE
Liquids containing solids, abrasives, powders, or paint pigments are
definitely not recommended for gear pumps. If abrasives are unavoidable, use a
very low shaft speed.
The recommended liquid temperature range is from 32o F to 140o F for best
pump life. If more extreme temperature conditions exist, factory should be
consulted. Freezing of water-filled pumps can cause damage and must be avoided.
Oils at low temperatures are very viscous requiring a lower speed or extra power.
FEATURES
• Compact design eases installation and use in limited space areas.
• Construction is bronze and stainless steel wetted components.
• Close tolerance design allows for consistent performance.
• Helical gears for quiet operation.
GENERAL DESCRIPTION
Pump housings and gears are made of top quality bronze, shafts are 303
stainless steel. Bearings are designed of high performance carbon-graphite material selected for wear resistance and long service life.
Gear pumps are positive displacement pumps. Each shaft revolution displaces a definite amount of liquid relatively unaffected by the back pressure in the
discharge line. Shaft speed and flow are directly proportional. Recommended pressure limits are 100 PSI for water and non-lubricants, 150 PSI for oil and other lubricants. The maximum shaft speed is 1750 RPM.
SHAFT SEALS
Close coupled gear pumps are normally supplied with a Buna N lip seal. A
lip seal made of Viton®* is available as an option. For a Viton®* Seal, add S5 to
the pump model number.
LIQUIDS AND TEMPERATURE
These pumps are suitable for all liquids that are compatible with bronze.
Most common liquids are water, oil, and mild chemicals in the pH range of 4 to 11.
Viscous liquids require reduced shaft speeds of 1150 RPM or lower.
(Consult factory.)

pumps.com
MODEL
SUCTION LIFT
As a general rule, the suction lift should be kept at an absolute minimum by
placing the pump as close to the liquid source as possible. A gear pump in new condition can lift 20 feet of water in the suction line. A foot valve (preferably with built-in
strainer) is recommended at the beginning of the suction line. For a first start-up, the
pump should be primed to avoid dry running. MInimum size of the suction pipe is
the size of the pump inlet port. For longer suction lines (over 3 feet) or for viscous
liquids, the pipe should be at least one size or two sizes larger than the pump inlet
port.
ROTATION AND RELIEF VALVE
If the discharge line contains any throttling devices such as a shut-off valve,
a spray nozzle or other restrictive device, it is necessary to have a relief valve in the
system which returns the liquid to the suction side or to the tank. The relief valve is
also available as part of the pump itself (R-model pumps). However, built-in relief
valves are only good for intermittent service. If used continuously, the pump will
overheat. A built-in relief valve is strictly a safety device against overpressure. It will
not work successfully as a pressure or flow control device. For this purpose a separate relief valve in the pressure line must be used.
Unless otherwise specified, the pump motor unit is supplied by the factory
for shaft rotation counterclockwise from shaft end. Reversing motor will reverse “in
and “out” ports and also requires changing relief valve location. The relief valve is
always on the inlet side of this pump series. The factory pressure setting is 50 PSIG.
To increase pressure, turn the relief valve adjusting screw in a clockwise direction.

Extremes of cold and heat will affect impeller life. Limits of
40o to 140o F should be observed. Do not allow liquid in pump to
freeze. Drain pump by loosening cover screws. Use methyl alcohol based anti-freeze compounds such as Zerex, Shell Zone,
Pyro Permanent, Permagard, Dowgard.
SUCTION LIFT
Suction lift of 3 ft. is possible when impeller is wet. Suction
lines must be air tight in order for pump to self prime. A foot valve
at the beginning of suction line is recommended.
FEATURES
• Compact Size
• Bronze Construction - Corrosion Resistance
• Buna Seal
• Large Vent Openings Separate Pump & Motor
• Stainless Steel Motor Shaft
• Motor Shaft Slinger Protects Motor Bearings
• Rubber Motor Grommets for Noise Isolation
• Impeller and Cam Easily Replaced
• Garden Hose Threads (External) &
Pipe Threads (Internal) for Port Connections
• Available with 12, 24 and 32 volt D.C. Motor Drive
MOUNTING
Horizontal motor mountings - including sidewall mountings - are recommended. The pump can be mounted in any
of 4 positions 90o apart. Two screws attach pump to motor.
DRIVE AND ROTATION
Motor drive is clockwise facing pump end. Liquid flow
direction is right to left facing pump end. Correct D.C. voltage must be supplied to motor - 12, 24 or 32 volts as specified on motor name plate.
DO NOT RUN DRY
Rubber impellers generate high rubbing friction unless
lubricated by the liquid pumped. Lack of liquid will cause
impeller to burn up.
LIQUID AND TEMPERATURE
Liquids compatible with neoprene can be pumped
including fresh and salt water solutions and mild chemicals.
Do not pump severe solvents or acids. When possible, flush
pump with fresh water after each usage.
IMPELLER REPLACEMENT
The impeller must be replaced if it is worn out or has been damaged by debris or by running the pump dry. Symptoms of a defective impeller are low pumping pressure and low flow causing overheating of the boat engine. Poor pump performance can also be
caused by slippage of V-belts, so belts should be checked for tightness.
To replace the impeller remove screws and cover. Pull out the
impeller with nose pliers or two screwdrivers. Be careful not to dent
the pumping chamber with these tools. When inserting new
impeller, line up key slot in impeller with the key in the shaft. Use oil
on shaft and avoid forcing the impeller onto the shaft.
The impeller should also be removed for storage periods to
prevent the blades from taking a permanent set.
SEAL REPLACEMENT
If water drips from the weep hole or from the area where the
shaft exits the pump, the seal is defective and must be replaced.
While the Teflon(R)* barrier seal provides a first line of defense,
prolonged running of the pump with a leaky seal can destroy the
ball bearings resulting in catastrophic pump failure and engine
shut-down.
For seal replacement, the pump must be removed from the
engine and disassembled in order to gain access to the seal area.
Where mechanical seals are used, both components (stationary
and rotating member) must be replaced at the same time. Lip seals
must be pushed out of their press-fitted position and new seals
pressed into place, using a sealant on the outside of the lip seal
housing.
Refer to exploded view drawings for seal location and part
numbers for ordering purposes.

DO NOT RUN DRY
Rubber impellers generate high rubbing friction
unless lubricated by liquid pumped. Lack of liquid will
cause impeller to burn up. Standard impeller in
Neoprene (04), optional Buna impeller (05) available.
SUCTION LIFT
Suction lift to 15 ft. for model 211D is possible when
impeller is wet. Suction lines must be air tight in order for
pump to self prime. Always use foot valve at beginning of
suction line to keep suction line full and impeller wet.
IMPELLER REPLACEMENT
The impeller must be replaced if it is worn out or has been
damaged by debris or by running the pump dry. Symptoms of a
defective impeller are low pumping pressure and low flow.
To replace the impeller remove screws and cover. Pull out
the impeller with nose pliers or two screwdrivers. Be careful not to
dent the pumping chamber with these tools. When inserting new
impeller, line up key slot in impeller with the key in the shaft. Use
oil on shaft and avoid forcing the impeller onto the shaft.
The impeller should also be removed for storage periods to
prevent the blades from taking a permanent set.
SEAL REPLACEMENT
If water drips from the area where the shaft exits the pump,
the seal is defective and must be replaced. While the shaft slinger
barrier seal provides a first line of defense, prolonged running of
the pump with a leaky seal can destroy the ball bearings of the
electric motor.
For seal replacement, the pump must be removed from the
motor and disassembled in order to gain access to the seal area.
The Buna seal must be pushed out of the press-fitted position and
a new lip seal pressed into place, using a sealant on the outside

FEATURES
• All Bronze Construction
• Stainless Steel Shafts
• Portable
• Compact
• Easy Impeller Replacement
• Macerator Easily Replaced
• Reversible Wear Plate
• Vacuum Switch Shut-off Optional
GENERAL DESCRIPTION
Close coupled Rubber Impeller Pumps are made
of high quality bronze for maximum corrosion resistance. The rubber impeller is either directly attached to
the stainless steel motor shaft or the impeller is
mounted on a separate stainless steel shaft which is
counterbored on the outer end in order to slide over
the carbon steel motor shaft. Ball or sleeve bearings in
the motor support the shaft. Model 406M has a
mechanical seal. Impellers are made of Neoprene rubber, Buna N impellers are available on request.
Flexible blades on the periphery of the impeller
provide the pumping action. While the impeller rotates,
the liquid between the blades is continuously
squeezed out into the discharge port by a cam located
inside the pumping chamber. The flow may be throttled or shut off for a short period without the need of a
relief valve.
DRIVE ARRANGEMENT
Close coupled Rubber Impeller Pumps are
mounted directly onto the electric motor without the
use of a shaft coupling. This pump is coupled to a
standard motors with Nema C flange. It uses a bronze
adapter plate to accommodate the pump.
www.oberdorfer-p
pumps.com
LIQUIDS AND TEMPERATURE
Liquids handled by Rubber Impeller Pumps with
standard Neoprene impellers are primarily fresh or salt
water and water solutions. Rubber Impeller Pumps are not
suitable for pumping gasoline or solvents. Buna N
impellers can handle oil contaminated water and kerosene
at reduced impeller service life.
Liquid temperature range is from 40o F to 140oF. If
freezing conditions are expected, the pump should be
drained by loosening the cover screws and the pump
chamber should be filled with antifreeze. Viscous liquids
and oils can not be pumped with Rubber Impeller Pumps.
SUCTION LIFT
On initial start-up Rubber Impeller Pumps must be
primed to prevent dry-running of the impeller. Suction lifts
of 15 ft. are possible when pump is fully primed. A foot
valve with built-in strainer at the beginning of the suction
line is recommended. Suction lines should be as short as
possible.

MODEL
101M
PIPE SIZE 3/8”
Capacity - Water at 60 o F
FEATURES
• All Bronze
• Stainless Steel or Monel Shaft for Marine Use
• Teflon(R)* Barrier Seal to Protect Motor Bearings
• Carbon Face Mechanical Pump Seals
• Will handle difficult solutions with proper seals Viton(R)* (S10) or Teflon(R)* (S11).
• Explosion Proof Motors Available
• Will Handle Contaminated Liquids
• Extremely Quiet
• A Standard in the Marine Air Conditioning Industry
LIQUIDS
The special pump alloys used provide corrosion resistance to many liquids including water, water solutions, and a
wide range of commercial chemicals. Questions as to the
chemical compatibility of special liquids should be referred to
the factory.
Viscous liquids with a maximum viscosity of 2000
Saybolt Seconds Universal can be pumped. However, when
pumping viscous liquids as compared with water, a reduction
in flow and pressure occurs and the required horsepower rate
increases.
Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity.
Liquids contaminated with small solids or abrasives can be
handled, but a reduction in mechanical seal life must be
expected.
CHARACTERISTICS
This close-coupled pump uses a standard NEMA CFlange Jet Pump Motor with weld-on base and threaded shaft
end to accept the pump impeller. Single phase motors are
non-reversible and are wired for the proper pump rotation
which is counter-clockwise looking at inlet end of pump. See
the dimensional drawing on back. Three phase motors must be
checked out for proper rotation when pump is installed. Interchanging
of any 2 wires in a 3-phase system will reverse motor rotation.
The pump uses a mechanical type shaft seal with a Buna rubber element. It is suitable for water, oils, and some mild solvents and
it is limited to 212 o F. Viton® seals and Teflon® seals (Chemlon) are
available for severe solvents, difficult chemicals, and elevated temperatures.
These centrifugal pumps are not self-priming. They must be
installed below the liquid level so that the liquid flows to the pump by
gravity (flooded suction). However, if a foot valve is used at the beginning of the suction line, and all air is bled from the pump by manual
priming, the pump will lift on the suction side up to 15 feet. Such a
system relies entirely on the non-leaking foot valve for starting capability.
The flow of a centrifugal pump can be conveniently controlled
by a throttling valve in the discharge line without the need for a relief
valve. In centrifugal pumps, the horsepower demand will decrease as
the pressure increases. Maximum horsepower occurs with a wide
open discharge.

LIQUIDS
One of the outstanding features of this pump and
motor unit is its compact D.C. motor size. Although small in
size, adequate motor power is available for pumping water,
water solutions, and a wide range of commercial chemicals.
Questions as to the chemical compatibility of special liquids
should be referred to the factory.
Viscous liquids with a maximum viscosity of 2000
Saybolt Seconds Universal can be pumped. However, when
pumping viscous liquids as compared with water, a reduction
in flow and pressure occurs and the required horsepower
rate increases.
Liquids heavier than water require additional horsepower in direct proportion to the increase in specific gravity.
www.oberdorfer-pumps.com
CHARACTERISTICS
Oberdorfer centrifugal pumps have a single rotating impeller.
Liquid enters at the center and is thrown outward radially by centrifugal force. The impeller is not in contact with other pump parts
resulting in quiet, efficient pumping action. The flow produced is not
positive which permits the discharge line to be shut off completely
without danger of overloading motors or bursting lines.
Consequently, a relief valve is not required.
These centrifugal pumps are not self-priming. They must be
installed below the liquid level so that the liquid flows to the pump
by gravity (flooded suction). However, if a foot valve is used at the
beginning of the suction line, and all air is bled from the pump by
manual priming, the pump will lift on the suction side up to 15 feet.
Such a system relies entirely on the non-leaking foot valve for starting capability.
The flow of a centrifugal pump can be conveniently controlled
by a throttling valve in the discharge line without the need for a
relief valve. In centrifugal pumps, the horsepower demand will
decrease as the pressure increases. Maximum horsepower occurs
with a wide open discharge.

using a foot or check valve and a filled inlet line). A 1/2” pipe
plug on the tank top is for initial filling of priming chamber and
inlet line--pump priming is automatic thereafter. Pump seal is
mechanical carbon face type mated to ceramic wear face for
maximum durability. Other seal components are made of
Buna N with low swell characteristics for compatibility with a
wide range of liquids including many chemicals and solvents.
These pump models are widely used for the pumping of
Perchloroethylene. Must be operated in the horizontal
position. (As shown in picture)

FEATURES
• Bronze Corrosion Resistant Castings
• Stainless Steel Shafts & Fasteners
• Self-Lubricating Carbon Bearings
• Packing (Braided Acrylic yarn with special lubricant and Graphite)
• For Mechanical Seals, see Models N11HDM
DRIVE
Either direct drive with flexible coupling or pulley drive can be
used. For pulley driven pumps a pillow block bearing must be used
at the drive shaft end to absorb the belt forces. The drive shaft is sufficiently long enough to accommodate a pillow block in addition to
the pulley.
Correct alignment is absolutely essential for satisfactory pump
life. Recheck alignment after the piping has been connected to the
pump.
LIQUIDS AND TEMPERATURE
Service life will be increased substantially if the liquid pumped is
clean and has a lubricity value. These pumps have extremely close
tolerances. Fine abrasives like sand, silt, or powders in suspension
will destroy pumping ability.
Liquids compatible with bronze, stainless steel and the acrylic
graphite packing can be pumped. Solvent resistant packings and
Teflon(R)* packings are also available. See a chemical compatibility
table or check factory. When possible, flush the pump with water
after using.
Temperature extremes are detrimental to service life and should
be avoided. Basic metals of construction allow temperature range of
-400F to 4000F. the acrylic graphite packing is rated to 5000F.
Freezing liquid in the pump can deform or damage the pump.
Viscous liquids such as molasses or oils require a lower pumping speed, in extreme cases as low as 200 R.P.M. Consult factory
for recommended speeds and increased horsepower requirements.
Note: Dotted lines(---) recommended for intermittent duty only
due to accelerated wear at higher speeds and pressures.
Large suction lines are required to prevent cavitation which can cause
pump destruction.
Liquids with specific gravities heavier than water such as dry cleaning
fluids require an increase in motor horsepower directly proportional to the
increase in specific gravity over water.
SUCTION LIFT
A rotary gear pump is capable of lifting water on the suction side as high
as 20 feet. Though gear pumps are self-priming, a foot valve is recommended. For pumping water directly from streams or ponds, a wire mesh
strainer must be used at the beginning of the suction line to prevent stones
from entering the pump. Strainer and foot valve are commercially available
as combination units.

PERFORMANCE
FEATURES
• Bronze Body & Gears, Stainless Shaft
• Self-lubricating Internal Carbon Bearings
• External Ball Bearing for Heavy Duty Belt Drive
• N994-38 has 1/2” NPT Ports
N970-38 has 3/4” NPT Ports
N990-38 has 1” NPT Ports
GENERAL DESCRIPTION
Pump housings are made of top quality bronze, shafts are
stainless steel 303. Bearings are made of high performance carbon-graphite material selected for wear resistance and long service life. Viton(R)* lip seal is suitable for fuel oils and the external ball bearings are for heavy belt drive loads.
Gear pumps are positive displacement pumps. Each shaft
revolution displaces a definite amount of liquid relatively unaffected by the back pressure in the discharge line. Shaft speed
and flow are directly proportional.
LIQUIDS AND TEMPERATURE
These pumps are suitable for all liquids that are compatible with bronze. Most common liquids are water, oil, and mild
chemicals in the pH-range of 4 to 11. Viscous liquids require
reduced shaft speeds of 1150 RPM or lower. Consult factory.
Liquids containing solids, abrasives, powders or paint pigments are definitely not recommended for gear pumps. If abrasives are unavoidable, use a very low shaft speed. The recommended liquid temperature range is 32 o to 140oF for longest
pump life. If more extreme temperature conditions exist, our factory should be consulted. Freezing of water-filled pumps can
cause damage and must be avoided. Oils at low temperatures
are very viscous requiring a lower speed or extra power.
SUCTION LIFT
As a general rule, the suction lift should be kept at an
absolute minimum by placing the pump as close to the liquid as
possible. A gear pump in new condition can lift 20 feet of water
in the suction line. A foot valve (preferably with a built-in strainer) is recommended at the beginning of the suction line. For a
(Continued on back)
first start-up, the pump should be primed to avoid dry running.
Minimum size of the suction pipe is the size of the pump inlet port.
For longer suction lines (over 3 feet), or for viscous liquids, the pipe
size should be at least one size or two sizes larger than the pump
inlet port.

PERFORMANCE (continued from front)
ROTATION AND RELIEF VALVE
The relief valve is not intended to be a metering or flow control device. It main purpose is to function as a discharge pressure
relief when the spring tension is exceeded by the discharge pressure. Overheating can occur within 5-10 minutes if the discharge
line is completely shut off for extended periods.
Unless otherwise specified, the clutch driven pump is supplied by the factory for shaft rotation clockwise from shaft end.
Reversing the rotation will reverse the “in” and “out” ports and also
requires changing the relief valve location. The relief valve is
always on the discharge side in this pump series. The factory
pressure setting is 50 PSIG. To increase pressure, turn the relief
valve adjusting screw in a clockwise direction.
