SECTION I
GENERAL DESCRIPTION
The Neptune Series 560 "dia-Pump" is a reliable metering pump of the hydraulically actuated diaphragm
type. Under constant conditions of temperature, pressure, and capacity adjustment settings, a plus or minus
range of 1 % metered discharge volume is maintained.
A plunger reciprocating at a fixed stroke displaces hydraulic fluid which actuates aflexible, chemically inert,
TeflonA, diaphragm to create pumping action. The capacity of the pump is regulated by controlling the
volume of hydraulic fluid which by-passes 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 eachstroke, 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.
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.
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.
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. Limit the total length of the
suction line to 3-4 feet suction lift or 6-7 feet flooded suction. Minimize bends, elbows, or
other restrictions.
Important
On single phase, integrally mounted motors, the rotation is set at the factory and must not
be changed.
On three phase, integrally mounted motors, rotation is determined by prying the 3/4"
diameter shaft cap from the top of the motor and noting the shaft rotation.
On all flange mounted motors the motor rotation may be viewed by removing the plug in
the opening on the side of the adapter.
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.

hydraulic fluid supplied through the fill opening at the rear of the pump. Pour fluid in slowly
until it has reached 1/4" below the bottom of the fill hole. Do not over fill as this can cause
damage to the motor.
Allow a few minutes for the hydraulic fluid to make its way into the pump chamber and then
recheck fluid level, reinstall Air Bleed Plug.

2.0 SUCTION PIPING
The suction piping to the pump must be absolutely air tight. It is suggested that the suction
piping be tested with low air pressure and a soap solution to assure that no leaks exist.
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 oper-
ate 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.
It is highly recommended that all solution tanks be purchased 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
3.0 DISCHARGEPIPING
3.0.1 It is recommended that the "dia-Pump" operate against a minimum discharge pressure of
50 psig. An anti-siphon spring is supplied loose with the pump. If 50 psig back pressure is
not provided by the application, the anti-siphon spring (FIG. #5666*) should be installed on
the pin under the vent plug (FIG. #5604*). Installation of the anti-siphon spring artificially
creates a discharge head.
*Refer to Drawing #C-OO2030 for appropriate N-5 pump part.
4.0 ADJUSTMENT OF INTERNAL RELIEF VALVE
4.0.1 All Neptune Series 560 "dia-Pumps" are supplied with an internally pre-set relief valve. THIS
RELIEF VALVE IS SET AT 175 PSI AND IS DESIGNED TO PROTECT THE PUMP SHOULD
A DISCHARGE PRESSURE BEYOND THE RATED LIMIT OF THE PUMP OCCUR.
If a customer order specifies a relief valve setting above those indicated above, the speci-
fied setting will be set at the factory. All pumps are tagged with the relief valve setting used
by the factory.
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 ifthe solution is by-passing through the valve
and returning to the tank, indicating a line blockage.
Drawing 5670 illustrates the location of the Internal Relief Valve (FIG. #5648 through #5652)
The drawing shows a passage connecting the hydraulic fluid reservoir with the hydraulic
fluid side of the diaphragm.
The passage is interrupted by the ReliefValve Ball (FIG. #5648) which is backed up by a
ReliefValveSpring (FIG.#5650).
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 ball is forced from its seat allowing the
hydraulic fluid to flow back to the reservoir.
6

4.0.2 To reset the relief valve to a higher pressure, (the relief valve setting cannot be reduced because
of 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 unt)1 all air is relieved from the discharge liquid (hand
valve open).
4.0.23 Remove ReliefValve Plug (FIG. #5651)c
4.0.24 Close hand valve; pressure gauge should read 175psi, depending on pump model.
4.0.25 Use 1/4" Allen wrench to adjust spring tension byturning Relief Valve Adjusting Screw
(FIG,#5652).
(1) Toincrease pressure, turn ReliefValveAdjusting Screw(FIG. #5652)In.
(2) To decrease pressure, turn Relief Valve Adjusting Screw (FIG. #5652) out.
4.0.26 After resetting or adjusting pressure, replace Relief Valve Plug (FIG. #5651).
CAUTION
Never turn Relief Valve Adjusting Screw (FIG. #5652) completely in.
Do not attempt to set the internal relief valve more than 200 psi in excess of name plate rating

5.0 INSTALLATION OUTDOORS
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:
Running of the pump when exposed to tropical sunshine with ambient temperature above
gooF (32°C) would cause excessive oil and motor temperatures. The pump should be shaded
and located in such a way as to permit ample air circulation.
Under cold conditions, the pump should be insulated and a heater should be supplied in order
to maintain the hydraulic fluid at an ambient temperature above 30°F (-1°C).
6.0 START UP PROCEDURE-FLOODED SUCTION
The following start up procedure is complete and does repeat instructions on filling the gear box
and pump.
Flooded Suction: Refer to Section I, Paragraph 1.0.9,for instructions on filling gear box with
hydraulic fluid. NOTE: Refer to Paragraph 12.3 for special start-up instructions after
replacing diaphragm.
6.0.2 After having let pump stand for 30 minutes and having rechecked fluid level, set pump capacity
indicator at approximately 30%. Be certain that pump suction and discharge tines are open.
Make certain that pumping chamber is flooded by loosening Vent Plug (FIG. #5604*) and
allowing solution to appear. Then tighten discharge vent plug. This procedure will also allow
airto vent from pumping chamber. The "dia-Pump" WILL NOT FUNCTION IF AIR IS TRAPPED
IN THE HYDRAULIC FLUID OR LIQUID PUMP CHAMBERS. Start pump.
'Refer to Drawing #C-OO2030 for appropriate N-5 pump part.
The pump is now ready for "on line" service. Calculate what the desired capacity as a per-
centage of either the maximum capacity rating on the pump data plate, or the nominal capacity
at the required system pressure.
START UP-SUCTION LIFT
7.0
7.0.1 Ifthe "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 suc-
tion line with one leg to the pump suction, one leg to the suction line, and one leg pointing straight
up and valved. Open valve and force prime pump and piping with water. Start pump.
WARNING: Beware of application where water is not compatible with chemica! to be pumped.
Example: Never force prime when pumping acid or oil based products.
8.0 START UP AFTER SUCTION HAS RUN DRY
In applications where the suction tank does not have a low level cutoff 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 SERVICE LIFE WILL BE SIGNIFICANTLY REDUCED WHEN THE
PUMP IS ALLOWED TO RUN WITH A DRY LIQUID Er<JD.
Before restarting a pump that has run dry and which has not damaged itself, follow the procedure in
Paragraphs 6.0 through 6.0.3 of Section II.

SECTION III
NORMAL MAINTENANCE
MAINTENANCE
Under normal conditions, the "dia-Pump" should not require any significant amount of maintenance.
It is advised that periodic visual observations be made of the oil level to make sure that it is within
1/4" of the bottom of the fill opening. The liquid end of the pump should also be inspected for leakage.
These observations should be made regularly, at least every 48 hours.
The hydraulic fluid should be drained and replaced TWICE a year, using the drain plug (FIG. #510)
on the side of the pump. This change can be scheduled with the normal factory maintenance at
seasonal periods.
CHECK VALVES: REMOVING, CLEANING, AND REPLACING
The "dia-Pump" incorporates a unique check valve design whereas the discharge and suction piping
NEED NOT be disturbed in order to service the valves.
Should the valves need cleaning, remove as follows:
10.0.1 Remove ventplug (FIG. #5604*)with anti-siphon spring (FIG. #5666*) ifinstalled.
10.0.2 Remove discharge cap (FIG. #5610*;
10.0.3 Remove suction cap (FIG. #5612*
10.0.4 With heavy wood dowel or bar of soft material, tap and push complete valve stack out of pump
from top through to bottom. The valve stack consists of:
4 Valve Balls (FIG. #2340*)
4 Valve Seats (FIG. #5695*)
1 Stack Spacer (FIG. #5693*)
3 Ball Guides (FIG. #5691*)
4 Valve Seat a-rings (FIG. #2342*)
10.0.5 Clean valve stack parts with suitable solvent. Replace in same order as removed from top to
bottom, putting suction valve cap (FIG. #5612*) in place with D-ring first.
*REFER TO DRAWING #C-OO2030 FOR APPROPRIATE N-5 PUMP PART.
CAUTION: Suction and discharge caps-Do not overtighten PVC 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.

SECTION VI
SPECIAL INSTRUCTIONS FOR SERIES 560 "dia-PUMPS" WITH
PNEUMATIC STROKE CONTROL
14.0 FUNCTIONOF THE PNEUMATICSTROKECONTROL 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. #5654).
The position change of the control unit can be observed on a capacity percentage scale seen through
the clear plexi-glass shell of the control unit.
The pneumatic control unit may be attached to any Series 560 "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. Ifthe 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 advice.
14.0.1 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. #5654) 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. #5654). The springs in the actuator and Moore control valves insure that the controlled
position is maintained without fluctuation. Only changes in the air signal will cause variations
in 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 the complete unit and the Moore control valve are included with the
instruction manual.
14.0.2 Maintenance
The Neptune "Pneumatic Stroke Control Unit" is normally maintenance free. Should,
however, any parts be required, use attached drawing No. 002387 and the parts list as an
assembly guide.
14.0.3 Moore Control Valve
If more complete information is required on the Moore Model 73N control valve, request
Moore Bulletin #8073-5 in writing from Neptune.

"N"-lndicates new part.
Valve stacks of all Series 560 (except PVC models) have been improved by the attention of close tolerance ball guides which allow
better accuracy and higher pressure performance.
Original and improved stack arrangements are shown in the figures on page 16.
Parts are currently furnished only for the improved version. When ordering replacement seats for an original valve stack design, order
the ball guides (FIG. #5691) and spacer (FIG. #5693). Installing these parts and discarding the old spacers (FIG. #2320 and FIG. #2326) will
upgrade the pump to the improved valve arrangement.
Ifseats are not replaced, it is not necessary to change the spacers and ball guides. If seats are replaced (the new seats are of a differ-
ent thickness) the ball guides and spacers must be replaced.
