SECTION I
GENERAL DESCRIPTION
The Neptune Series 500 “dia-PUMP” is a reliable metering pump of the high-pressure diaphragm type. Under
constant conditions of temperature, pressure, and capacity adjustment settings, a +/- 1% metered discharge volume
is maintained.
A plunger reciprocating at a fixed stroke displaces hydraulic fluid, which actuates a flexible, chemically inert, Teflon
diaphragm to create pumping action. The capacity of the pump is regulated by controlling the volume of hydraulic
fluid, which bypasses the diaphragm cavity.
Capacity adjustment can be made manually or automatically by instrument signal.
Metering accuracy is maintained by a control rod, which allows hydraulic fluid replacement and air venting
automatically with each stroke, while also taking into account temperature changes of the hydraulic fluid. Metering
accuracy is also insured by the use of double ball check valves on the suction and discharge of the pump.
PLEASE READ THE INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING THE PUMP.

SECTION II
INSTALLATION INSTRUCTIONS
1.0 GENERAL
1.0.1 When unpacking a pump or chemical feed system, be certain that no parts are thrown away.
Examine the equipment for possible damage. If damage has occurred, file claim with the common
carrier within 24 hours. Neptune will assist in estimating the repair costs.
1.0.2 The ‘‘dia-Pump’’ should be located so as to avoid an ambient temperature above 120°F, 50°C. Free
air circulation is important when considering the location of the pump.
1.0.3 The ‘‘dia-Pump’’ should be located on a level surface. Three mounting holes are provided to anchor
the pump securely to the mounting surface. PVC head pumps must be mounted on three, one-inch
spacers provided.
1.0.4 All piping to the pump should be supported to prevent stress on the pump input and out-put fittings.
1.0.5 Before connecting the pump, make sure that all fittings are completely clean by flushing thoroughly.
Any foreign matter entering the pump can damage the internal parts and severely limit the life of the
pump.
1.0.6 A ‘‘Y’’ STRAINER MUST BE INSTALLED IN THE SUCTION LINE OF THE PUMP TO INSURE
AGAINST FOREIGN MATTER ENTERING THE PUMP. ALL SUCTION LIFT APPLICATIONS
REQUIRE A FOOT VALVE STRAINER TO PREVENT LOSS OF PRIME, AND TO PREVENT
FOREIGN MATERIAL FROM ENTERING THE PUMP.
1.0.7 Shut-off valves and unions should be placed in the suction and discharge lines to facilitate servicing
the pump.
1.0.8 Care should be exercised when piping to PVC head pumps. In cases where vibration or stress is
unavoidable, flexible connections should be used.
1.0.9 The electrical supply to the pump must match the motor name plate characteristics. The motor
rotation is counter clockwise when viewed from the top of the motor, looking down on the pump.
(See Figure 1).
1.0.10 Discharge Piping should be the same size or larger than the discharge connection. Suction Piping
should be one size larger than the suction connection (1/2” pipe minimum). Limit the total length of
the suction line to 3-4 feet suction lift or 6-7 feet flooded suction. Minimum bends, elbows, or other
restrictions.
Important
On single phase integral motors, the rotation is set at the factory and must not be changed.
On three phase integral motors, rotation is determined by noting the fan rotation.
On some flange mounted motors, the motor rotation may be viewed by removing the cap on
the side of the flange. There is no viewing port or coupling access on the close coupled
flange mount motors. Rotation is checked by removing the oil fill plug an observing the gear.
Correct rotation is indicate by the gear teeth moving downward away from the oil fill hole.
Please note Figure 1, indicating the correct rotation. (An arrow on the gear box also indicates
proper rotation.) Operation with the incorrect rotation will damage the pump and motor.
Models 481 and 501 must be installed with a flooded suction. These models will not operate with
suction lift.

1.0.11 Set capacity knob to zero and remove Air Blee d Plug from the top of Oil Chamber, refer to dra wings HP-1102 (page 21)
for Series 500 and drawing 5024 (page 27) for Series 50 0-A and 500-E for location of plug. Fill gear box and p ump by
pouring the hydraulic fluid supplied through the fill opening at the rear of the pump. Pour fluid in slowly until it has
reached the correct level per Figure 1A. Do not over fill as this can cause damage to the motor.
Allow a few minutes for the hydraulic fluid work through the oil head and appear at the oil bleed plug. Recheck oil level.
When air is purged, reinstall the Air Bleed Plug.

High Pressure Oils
The 90 weight gear oil is used for high-pressure pumps using 1/2 horsepower motors or larger and rate d for operation
over 1000 PSI.
The 90-weight gear oil is also provided for the 481, 500, and 501 pump models at all pressures.
2.0 SUCTION PIPING
2.0.1
The suction piping to the pump must be absolutely air tight. It is suggested that the suction pipin g be tested with
low air pressure and a soap solution to assure that no leaks exist.
2.0.2 NEPTUNE RECOMMENDS THAT THE ‘‘dia-Pump’’ BE OPERATED WITH A FLOODED SUCTION, AS THIS
WILL FACILITATE START UP AND INCREASE THE SERVICE LIFE OF THE PUMP. It is, however, possible to
operate the ‘‘dia-Pump’’ with a suction lift of up to 5 feet, if absolutely necessary. A FOOT VALVE STRAINER
must be used on this type of application. Model 481 and 501 require a flooded suction.
2.0.3 It is highly recommended that all solution tanks be furnished with a low level cut off switch or low level alarm and
cut off switch to prevent the pump from running dry. OPERATION AGAINST A DRY SYSTEM WILL CAUSE
DAMAGE TO THE PUMP DIAPHRAGM AND REDUCE THE OPERATING LIFE OF THE PUMP.
2.0.4 The single, safest rule of thumb for selecting suction pipe size is to use the same size or one siz e larger than
the pump suction connection (1/2” pipe minimum).
5
3.0 DISCHARGE PIPING
3.0.1 It is recommended that the ‘‘dia-Pump’’ operate against a minimum discharge pressure of 50 psig. A
back pressure spring is supplied loose with the pump. If 50 psig back pressure is not provided by the
application, the back pressure spring should be installed on the pin under the discharge valve cap.
Installation of the back pressure spring artificially creates a discharge head. (Refer to Figures II and
III.) Note: Spring is not provided in 500-E Series.
3.0.2 Take care to use piping suitable for the discharge pressure.

4.0 ADJUSTMENT OF INTERNAL RELIEF VALVE
4.0.1 All Neptune Series 500 dia-Pumps are supplied with an internal relief valve preset to 200 psi.
The internal relief valve is designed to protect the pump itself should a discharge pressure beyond the relief
valve setting occur.
If a customer order specifies a relief valve setting above those indicated above, the specified setting will be
set at the factory. All pumps are tagged with the relief valve setting used by the factory.

4.0.1 (Continued)
4.0.2 To reset the relief valve to a higher pressure, (the relief valve setting cannot be reduced because of
To protect the external piping system, it is recommended that a relief valve as manufactured by
Neptune Chemical Pump Company, or equal, be placed in the discharge line of the pump. It is
further recommended that this relief valve be piped into return of the tank with clear PVC tubing so
that it can be determined if the solution is by-passing through the valve and returning to the tank,
indicating a line blockage.
Drawing HP-1101 (page 23) illustrates the location of the Internal Relief Valve for Series 500 (FIG.
#527 through #530). See drawing 5024 (page 29) for Series 500-A and 500-E.
The drawing shows a passage connecting the hydraulic fluid reservoir with the hydraulic fluid side of
the diaphragm.
The passage is interrupted by the Relief Valve Poppet (FIG. #527) which is backed up by a Relief
Valve Spring (FIG. #528).
If, during the pump operation, the pressure on the hydraulic fluid side of the pump exceeds the set
pressure of the internal relief valve, the poppet is forced from its seat allowing the hydraulic fluid to
flow back to the reservoir.
design considerations) instructions are as follows:
4.0.21 Connect a test set-up as shown in Figure IV below.
4.0.22 Start and run the pump until all air is relieved from the discharge liquid (hand valve open).
4.0.23 Remove Relief Valve Plug (Fig.#530).
4.0.24 Close hand valve; pressure gauge will read the internal relief valve setting which should
agree with the pressure setting on the tag if the pump is new. The desired setting is 100 psi
above the operating pressure of the system into which the pump is injecting. Do not adjust
lower than 200 psi.
4.0.25 To change the relief valve pressure setting, use the 3/16” Allen Wrench to adjust spring
tension by turning Relief Valve Adjusting Screw (FIG. #529).
(1) To increase pressure, turn Relief Valve Adjusting Screw (Fig. #529) in.
(2) To decrease pressure, turn Relief Valve Adjusting Screw (Fig.#529) out.
4.0.26 After resetting or adjusting pressure, replace Relief Valve Plug (Fig. #530).
Never turn Relief Valve Adjusting Screw (Fig. #529) completely in.
Do not attempt to set the internal relief valve more than 200psi in excess of name plate rating.

5.0 INSTALLATION OUTDOORS
6.0 START-UP PROCEDURE (FLOODED SUCTION)
PVC Head Pumps –Discharge Valve Cap (P/N 000256 on page 22) is loosened by loosening Valve Cap Screws
The “dia-pump” is a totally enclosed pump which can be used outdoors or indoors. When installed outdoors, make sure
that the pump is protected against extremes of nature as follows:
5.0.1. Running of the pump when exposed to tropical sunshine, with ambient temperature above 100ºF, 38ºC would
cause excessive oil and motor temperatures. The pum p should be shaded and located in such a way as to
permit a high degree of air circulation.
5.0.2 Under cold conditions, the pump should be insulated and a heater should be supplied in order to mai ntain the
hydraulic fluid at an ambient temperature above 30ºF, -1ºC. Heat may be provided by a 100 watt bulb or a
heater tape, etc.
The following start-up procedure is complete and does repeat instructions on filling the gear box and pump.
6.0.1 The gear bo x should be filled with hydraulic fluid per the inst ructions in par agra ph 1.0.11. Let the pump stand for
30 minutes and then recheck fluid level. Be certain that pump discharge lines are open.
6.0.2 Confirm that the liquid head is flooded and no air remains per the follo wing paragraphs. Pumps should not be
running. Wear appropriate protective gear when performing any step that involves contact with the chemical.
6.0.2.1 SERIES 500 and 500-A METAL HEAD
Make certain that pumping chamber is flooded and air is purged by loosening Discharge Valve Cap (FIG.#536
on page 21) approximately 2 to 3 turns and allo wing solution to appear. Then, tig hten discharg e valve cap. T his
procedure will also allow air to vent from pumping chamber. THE “dia-PUMP” WI LL NOT FUNCTION IF AIR IS
TRAPPED IN THE HYDRAULIC FLUID OR LIQUID PUMP CHAMBERS.
6.0.2.2 SERIES 500 AND 500-A PVC HEAD
(P/N 100250).
6.0.2.3 SERIES 500-E (See page 25)
6.0.3 Follow the procedur e below:
1. Make certain that the suction line, liquid end and discharge cartridge chamber are filled with water or
system fluid.
2. Set the capacity control knob to approximately 30-40% of maximum capacity.
3. On initial start-ups: Check for proper motor rotation (Refer to Paragraph 1.0.9). Run the pump for 10-20
seconds, then stop for 20-30 seconds. Repeat a few times. During these short runs, listen for an y abn or mal
motor or crank noises, and if present, refer to Trouble Shooting Chart.
8
4. On initial gearbox fill or after replacing hydraulic fluid, run pump for one-half to one hour to warm
up oil and allow air bubbles to dissipate. Check discharge line for indication of flow.
5. Once discharge flow is observed proceed to paragraph number 6; if no flow, repeat steps 3 and
4.
6. Increase capacity adjustment setting to 70% of maximum capacity and operate for 10-20
minutes.
7. Reduce capacity adjustment setting to 30-40% of maximum capacity and operate for several
minutes, then increase capacity adjustment back to 100% for approximately 10 minutes. Repeat
several times to insure that the air is bled from the hydraulic fluid side and the liquid side.
6.0.4 The pump is now ready for “on line” service. Calculate what the desired capacity as a percentage of
either the maximum capacity rating on the pump data plate, or the nominal capacity at the required
system pressure.
7.0 START-UP PROCEDURE (SUCTION LIFT) SERIES 500 AND 500-A.
(See page 24 for SERIES 500-E) MODELS 481, 501 AND 510 REQUIRE A FLOODED SUCTION.
7.0.1 If the “dia-Pump” is to be used where suction lift is required, A FOOT VALVE STRAINER MUST BE
INSTALLED on the end of the suction line. A pipe tee is installed on the top end of the suction line
with one leg to the pump suction, one leg to the suction line and one leg pointing straight up and
plugged. Remove plug and fill piping assembly with liquid. Replace plug. Start pump and follow
procedure per Paragraph 6.0.3.
Use the following procedure only if required:
7.0.2 Remove Discharge Valve Cap (FIG. #536). Then, using Allen wrench provided, remove Discharge
Valve Nut (FIG. #543). The Discharge Valve Nut (FIG. #543) is stamped with the letter “T” to indicate
the face which should be installed toward the top on reassembly. Finally, remove Discharge Valve
Cartridge (FIG. #539) using special blade provided. Fill the pumping chamber. Replace parts and
then follow instructions per Section II, Paragraph 6.0.3. Repeat entire procedure if pump loses prime
or runs dry. (See Figures VI and VII.)
NOTE
PVC Head Pumps –Remove Discharge Valve Cap (P/N 000256) by removing Valve Cap Screws
(P/N 100250). Next, remove Discharge Valve Cartridge (P/N 000259) using special round lug tool
provided. Fill pumping chamber. Replace parts and then follow instructions per Section II
Paragraph 6.0.3. (Refer to Figure VII.)
CAUTION
Do not overtighten PVC valves as the PVC material is not able to withstand excessive force and can
fail. Teflon® paste is an excellent thread lubricant and may be applied.
8.0 START-UP AFTER SUCTION HAS RUN DRY
In applications where the suction tank does not have a low level cut-off interconnected into the pump motor
circuit, the pump may occasionally run dry. THIS MUST BE AVOIDED BECAUSE DAMAGE TO THE PUMP
CAN RESULT AND THE SERVIC LIFE WILL BE SIGNIFICANTLY REDUCED WHEN THE PUMP IS
ALLOWED TO RUN WITH A DRY LIQUID END.
Before restarting a pump that has run and which has not damaged itself, follow the procedure in Paragraph 6.0
through 6.0.3 of Section II, except it is not necessary to warm up the oil.

SECTION III
NORMAL MAINTENANCE AND DISASSEMBLY INSTRUCTIONS
9.0 MAINTENANCE
Under normal conditions, the “dia-Pump”does not require any significant amount of maintenance. It is
advised that periodic visual observations be made of the oil level. See Page 5 for correct oil level. The liquid
end of the pump should also be inspected for leakage. These observations should be made regularly, at
least every 48 hours.
10.0 REMOVAL OF VALVE CARTRIDGES (See page 27 for SERIES 500-E; Page 30 for 500-V)
The “dia-Pump” incorporates a unique check valve design whereas the discharge and suction piping NEED
NOT be disturbed in order to service the valve cartridges.
Should the valves need cleaning, remove as follows:
10.0.1 Suction Valve: Remove Suction Valve Cap (FIG. #550) and using Allen Wrench provided, remove
Suction Valve Cartridge (FIG. #544).
NOTE
PVC Head Pump – Remove Suction Valve Cap (P/N 000256) by removing the Valve Cap Screws
(P/N 100250) and remove Suction Valve Cartridge (P/N 000259) using the special round lug tool
provided. Caution: PVC is fragile – do not use excessive force.
10.0.2 For removal of discharge valve, refer to instruction in Section II, Paragraph 7.0.2.
10.0.3 Please refer to Figures VI and VII showing valve cartridge removal.
11.0 CLEANING OF VALVE CARTRIDGES
11.0.1 The valve cartridge is a complete and integral unit and should not be disassembled for cleaning. If
the valves are found to be worn and in need of replacement, an entire valve cartridge, either suction
or discharge, should be ordered. The suction valve is the longer of the two valve cartridges.
11.0.2 To clean the valve cartridges, soak in strong detergent and then blow dry with compressed air.
12.0 REPLACING OF VALVE CARTRIDGES (See page 27 for SERIES 500-E)
12.0.1
Be certain that the Valve Seat “O” Ring (FIG. #549 for Metal Head Pumps, P/N 100185 for PVC
Head Pumps) is removed with the valve and that no other foreign matter is in the valve cavity.
Use a small amount of grease to hold the “O” ring in the groove in the end of the valve cartridge on
reassembly.
Reverse the procedure used to remove the valve cartridge. Do not over-tighten valve cartridge. Firm
tightening is enough to cause the “O” Ring to seal.

as an integral part of the pump itself.
The normal temperature rise for this motor is 40ºC above ambient temperature and thus, it might appear that the motor is
operating at a higher than normal temperature. This situation is normal and should not cause concern.
As a precaution against motor overheating, it is recommended th at the pump be located where adequate ventilation is
available. It is also highly RECOMMENDED THAT A MOTOR STARTER WITH THE PROPER OVERLOAD
PROTECTION BE SUPPLIED AS AN ADDITIONAL SAFETY DEVICE.
The Standard Series 500 “dia-Pump” (1/3HP/1/115V/60C/TEFC) motor is supplied with built-in thermal protection.
Automatic overload is provided on all pumps with standard motor with serial numbers higher than 9600-78D.
Should an overload occur on a standard motor unit which is not protected by a motor starter, or on such a unit where the
starter has failed, the motor will shut down automatically. It will take approximately ½ hour for the automatic thermal
overload switch to reset itself.

SEE ELECTRIC STROKE CONTROL INSTRUCTION MANUAL
FOR PUMPS FURNISHED WITH OPTIONAL ELECTRIC STROKE CONTROL.
SPECIAL INSTRUCTIONS FOR SERIES 500 “dia-Pumps”
WITH PNEUMATIC STROKE CONTROL
17.0 FUNCTION OF THE PNEUMATIC STROKE CONTROL UNIT
The Neptune pneumatic stroke control unit controls the capacity of the “dia-Pump” over the full operating
range. Control is normally effected by an instrument air signal of 3 to 15 psi applied to a Moore Products
Model 73N control valve (other air signal parameters also available), which is an integral part of Neptune
stroke control unit.
The variation of instrument air signal changes the air pressure on the Diaphragm (FIG. #583) in the control
unit, which in turn changes the position of the Pump Capacity Control Rod (FIG. #570).
The position change of the control unit can be observed on a capacity percentage scale seen throug h the
clear plexi-glass shell of the control unit.
The pneumatic control unit may be attached to any standard simplex or duplex Series 500”dia-Pump”.
The operating range of supply air may vary between 40 and 80 psi. The Moore control valve is preset at the
factory for a supply air pressure of 60 psi.
The “Pneumatic Stroke Control Unit” is accurately preset and tested at the factory. If the unit does not appear
to perform correctly, please contact your local representative or the factory. Do not attempt to adjust the unit
in the field without factory advise.
17.0.1 The Moore control valve which is attached to the Neptune actuator supplies a varying air pressure to
the Flexible Diaphragm (FIG. #583) which is in turn, balanced by Operating Spring (FIG. #587). The
Capacity Control Rod (FIG. #570) is attached to this system.
With the required air signal, the Moore control valve maintains the correct constant air pressure on
the Flexible Diaphragm (FIG. #583); i.e. constant position of the Capacity Control Rod (FIG. #570).
The springs in the actuator and Moore control valve insure that the controlled position of the
diaphragm (i.e. capacity control rod). Supply air and instrument input ports are clearly marked on the
Moore Control Valve.
The Moore control valve connections are marked for “Supply Air” and “Instrument Air”. It is important
that clean, dry air be furnished to the “Pneumatic Stroke Control Unit”. Cross sectional drawings of
17.0.2 Maintenance

The Neptune “Pneumatic Stroke Control Unit” is normally maintenance free.

NOTE: PRIMING PROCEDURE
Series 500-E pumps have no anti-siphon spring to defeat when priming, they also do not have a valve cap to vent and bleed air.
To bleed air on initial start-up it will be necessary to open a valve to the atmosphere in the discharge line before the first isolation
valve. If there is no valve in the particular installation, then breaking the piping connection at tubing joint or union will allow the air
to escape while the pump is primed. This is only required when first starting a new installation. Since there is no anti-siphon
spring, it is necessary to install a backpressure valve in the line when pumping to atmospheric or low-pressure injection poi nts.

SERIES 500-VS
HIGH VISCOSITY
INTRODUCTION
The Neptune Series 500 “dia-Pump” is available with a special liquid end to handle higher viscosity liquids.
Model numbers of pumps are for example 515-VS-N3 or 535-VS-N3.
This liquid end, which is only available in 316SS, is different than the standard liquid end as the suction
valve, back up plate, and liquid head are modified to allow oversized porting to enable thick liquids to be
drawn into the pump on the suction stroke. All other parts of the pump are identical to the standard pump.
Note, the suction connection is directly up from below and the normal suction connection is plugged. The
pump must be elevated as the inlet connection is plugged. The pump must be elevated as the inlet
connection extends below the plane of the gear box seat.
Maintenance instructions are identical to the standard pump. The four parts which are different from the
standard unit are shown below.

MODEL 481
LOW VOLUME PUMP
INTRODUCTION
A special version of the Neptune Series 500 Pump is the Model 481. This pump is different than the standard
pump due to the unique Low-Flow design, which involves a smaller Piston and Metering Device with extremely
close tolerances. (Correct installation is critical for proper pump operation.) The valves used in this p ump also
contain smaller ball checks and seats. Refer to Parts Drawing S00091 for cross-sectional details. This drawing
also indicates each part of the Model 481 that is not common to the other pumps within the Series 500.
Generally, the maintenance and repair procedures for the Model 481 are the same as those shown in the
Operating and Instruction Manual for the Series 500 and 500-A Pumps. Failure to follow these instructions
could cause pump output to become erratic, or stop altogether.
PUMP CALIBRATION
Each pump is tested at the factory prior to shipment to assure proper operation without leakage at the
maximum capacity and discharge pressure specified, with a constant flooded suction of 2 feet of water. For
precise capacity control in the field, a calibration test under actual operating conditions with the actu al piping
arrangements is frequently desirable. Use a calibration drawdown cylinder in the suction line.
After the suction and discharge lines are piped with a convenient sampling point in the suction line, and the
pump has been suitably primed, test samples are collected at 25%, 50% 75% and 100% capacity settings. A
straight line results when these points are plotted on graph paper. This graph can be used as a calibration
curve for an intermediate setting as long as suction and discharge conditions remain constant.
It is important to realize that the sample at 50% will not necessarily be 1/2 that of 100%, nor will any other
sample points be to a specific percentage of the 100% value, but the pump will give repetitive samples at the
same setting. This is due to the extremely low volume of the pump which results in a shifting zero flow point as
pressure increases and can be seen in the curve below.

DOUBLE DIAPHRAGM OPTION
ADDENDUM: Special instructions for Series 500, 500-A & 560 “dia-Pumps” with Double Diaphragm
THEORY OF OPERATION
The instructions below are for Neptune’s optional Double
Diaphragm Kit which is available for the Neptune Series
500, 500-A, and 560 “dia-Pumps”.
Use of a double diaphragm allows diaphragm to be
monitored and provides an early warning upon failure of
either diaphragm allowing repairs to be made before
process fluid mix with the pump hydraulic fluid.
Neptune’s double diaphragm is a kit which may be
retrofitted to any pump currently in service or may be
installed on a new pump at the factory.
Figure 1 illustrates a Double Diaphragm Assembly. An
intermediate plate is located between the oil and liquid
heads with one diaphragm on each side of the
intermediate plate. The Intermediate Plate is connected
to a rupture alarm or pressure switch via a capillary
system. The area between the diaphragms is
evacuated. Rupture in either diaphragm produces an
increase in volume and, therefore, a pressure increase,
which can be sensed by a pressure switch for alarm
purposes.
