SECTION I
GENERAL DESCRIPTION
The Neptune MP7000 Mechanical Diaphragm metering pump is a reliable metering pump of the low-pressure diaphragm
type. Under constant conditions of temperature, pressure, and capacity setting, a +/- 2% metered discharge volume is
maintained. Rugged contoured composite diaphragm designed for high metering accuracy over a full 10:1 turndown
range.
A reciprocating rod at a set stroke length and rate actuates a flexible, chemically inert, Teflon faced diaphragm creating
the pumping action. Screwing in and out a hand knob regulates the capacity of the pump. Screwing in shortens the stroke
length reducing the volume and screwing out increases capacity. A percentage of flow is read on the hand knob.
Precision-engineered liquid ends meters mild solutions, aggressive chemicals, high viscosity polymers (up to 200cP) and
slurries (hydrated lime slurries up to 4 lb/gallon of water, activated carbon slurries up to 1 lb/gallon of water). If metering of
liquids with higher viscosity is required please contact factory
Metering accuracy is maintained by the ball check valves in the suction and discharge pump heads. Screw-in cartridge
ball check valves eases maintenance.
Temperature limitations on the plastic heads are: 36 – 125°F (2 - 52°C) for PVC; 36 - 200°F (2-93°C) for PVDF.
PLEASE READ INSTRUCTION MANUAL COMPLETELY BEFORE INSTALLING PUMP.

SECTION II
INSTALLATION INSTRUCTIONS
1.0 GENERAL
1.0.1 UNPACKING & INSPECTION
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 a claim with the common carrier within 24
hours. Neptune will assist in estimating the repair costs.
1.0.2 The Mechanically Actuated Diaphragm metering pumps should be located on a level surface. Four
mounting holes are provided to anchor the pump base securely to the mounting surface. All piping to the
pump should be supported to prevent stress on the pump inlet and discharge fittings.
1.0.3 Before connecting the pump make sure that all fittings are completely clean by flushing thoroughly.
Foreign matter with sharp edges entering the pump can damage the diaphragm and severely limit the life
of the pump.
1.0.4 A “Y” STRAINER (AT LEAST ONE PIPE SIZE LARGER THAN SUCTION PORT SIZE OF THE PUMP)
MUST BE INSTALLED IN THE SUCTION LINE OF THE PUMP TO INSURE AGAINST FOREIGN
MATTER ENTERING THE PUMP
1.0.5 It is recommended that isolation valves and unions be placed in the suction and discharge lines if
possible. Such an arrangement will facilitate servicing the pump.
1.0.6 The electrical supply to the pump must match the motor nameplate characteristics. The motor rotation is
counterclockwise when viewed from the top of the motor or looking down on the pump.
1.0.7 Do not fill pump with oil. Pump is designed with oil free gearbox.
IMPORTANT: On single-phase units, the rotation is set at the factory and must not be changed
Page 10
9
NOTE: THE FACTORY SUPPLIED CHECK VALVES ARE FITTED WITH VITON O-RINGS. CHECK CHEMICAL
COMPATIBILITY, IF NOT COMPATIBLE REPLACE WITH SUPPLIED TEFLON O-RINGS.
All piping systems should include:
1.1.1 A separate system relief valve to protect piping and process equipment, including the pump, from excess
process pressures.
*An external relief valve is required to safeguard pump and the piping system.
1.1.2 Isolation valves and unions (or flanges) on suction and discharge piping. This permits check valve
inspection without draining long runs of piping. Isolation valves should be of the same size as
connecting pipe. Full flow ball valves are preferred since they offer minimum flow restriction.
1.1.3 An inlet strainer, if the product is not slurry. Pump check valves are susceptible to dirt and other solid
contaminants unless designed for that service, and any accumulation can cause malfunction. The strainer
should be located between the suction isolation valve and the pump suction check valve. It must be sized
to accommodate the flow rate and the anticipated level of contamination. A 100-mesh screen size is
recommended.
1.1.4 Check valve housings or other portions of the liquid head must not support piping weight, as the resulting
stresses can cause leaks. In piping assembly, use a sealing compound chemically compatible with the
process material.
SUCTION PRESSURE REQUIREMENTS
Although Mechanical Diaphragm metering pumps have suction lift capability, a flooded suction is
preferable whenever possible. The pump should be located as close as possible to the suction side
reservoir or other source keeping suction piping as short as possible.
The pump will self-prime with 10 ft. (3 meters) of water suction lift (wetted valves, zero back pressure, full
stroke and speed, water like solutions). A foot valve is required to maintain prime. Once primed, the
pump is capable of up to 20 feet (6 meters) of water suction lift.
Neptune Mechanically Actuated Diaphragm metering pumps are designed for continuous service at the
rated discharge pressure. The discharge pressure must exceed suction pressure by at least 25 psiA (or
1.75 Bar). This can be achieved where necessary by the installation of a backpressure valve in the
discharge line.
2.0 SUCTION PIPING
2.0.1 The suction piping to the pump must be absolutely airtight for optimum operation. Any leakage in the
suction line will reduce or even eliminate pumping capacity. Suction pipe should be at least one size
larger than suction port size of the pump’s Liquid Head. It is suggested that the suction piping be tested
with low air pressure and a soap solution to assure that no leaks exist. Limit the total length of the suction
line to 5-8 feet for suction lift or 8-10 feet for flooded suction. Minimize bends, elbows, or other restrictions
for better pumping efficiency.
2.0.2 NEPTUNE RECOMMENDS THAT THE MECHANICALLY ACTUATED DIAPHRAGM METERING
PUMPS BE OPERATED WITH A FLOODED SUCTION, AS THIS WILL FACILITATE START-UP AND
INCREASE THE SERVICE LIFE OF THE PUMP.
2.0.3 It is 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. Although the pump can run dry for a few
minutes, OPERATION AGAINST A DRY SYSTEM UNDER PRESSURE FOR A PROLONGED PERIOD
MAY CAUSE DAMAGE TO THE PUMP DIAPHRAGM AND REDUCE THE OPERATING LIFE OF THE
PUMP.
Page 11
10
3.0 DISCHARGE PIPING
3.0.1 It is recommended that the Mechanically Actuated Diaphragm metering pump operate against a suitable
back pressure to facilitate better operation of the check valves.
3.0.2 To protect the pump, it is recommended that an external relief valve as manufactured by Neptune Chemical
Pump Company, or equal, be placed in the discharge line of the pump to avoid over pressure.
3.0.3 Discharge piping should at least equal to discharge port size of the pump’s Liquid Head.
NOTE: All pipes and valves must have a working pressure at least twice the system maximum pressure.
CAUTION: Do not attempt to run the pump in excess of its nameplate rating.
4.0 INSTALLATION OUTDOORS
The Mechanically Actuated Diaphragm metering 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:
4.0.1 Running of the pump when exposed to tropical sunshine with ambient temperature above 100°F (37.8°C)
would cause excessive motor temperatures. The pump should be shaded and located in such a way as to
permit an ample degree of air circulation.
5.0 START UP PROCEDURE
The following start up procedure is complete and does repeat instructions on filling the gearbox and pump.
5.0.1 Open suction and discharge valves. (See recommendation 1.0.5)
5.0.2 Set capacity control knob to indicate zero by turning clockwise.
5.0.3 Adjust backpressure close to zero.
5.0.4 Start pump.
5.0.5 On initial start-ups: Check for proper motor rotation (Refer to Paragraph 1.0.6). Listen for any abnormal
motor or crank noises, and if present, refer to trouble shooting chart (page 21)
5.0.6 Adjust pump to required capacity by turning hand knob counterclockwise.
5.0.7 Adjust system pressure to requirement.

SECTION III
NORMAL MAINTENANCE
6.0 MAINTENANCE
Under normal conditions, the Mechanically Actuated Diaphragm metering pumps should not require any
significant amount of maintenance. The liquid end of the pump should also be inspected for leakage and check
the liquid head bolt torque. These observations should be made regularly.
6.1.0 CHECK VALVE REMOVAL CLEANING AND REPLACEMENT.
Should the valves need cleaning, remove as follows:
6.1.1 Disconnect the power source to the drive motor.
6.1.2 Relieve all pressure from the piping system.
6.1.3 Close the isolation valves on suction and discharge piping.
6.1.4 Loosen and remove the suction and discharge check valves gradually to drain any trapped
liquid.
6.1.5 Clean valves with suitable solvent. Both valves are complete and integral units and should
not be disassembled for cleaning. If the valves are found to be worn and in need of
replacement, an entire valve in either suction or discharge should be ordered.
6.1.6 To replace, reverse above procedures. Make sure that the port orientation is correct.
6.1.7 For valves with O-rings make sure that the O-rings are in good condition. Install new
O-rings if necessary.
6.2.0 LIQUID HEAD REMOVAL, INSPECTION, AND REINSTALLATION
CAUTION: If the diaphragm failed, process fluid will pass through the bleed hole located behind the diaphragm. Handle any liquid with appropriate care.
(Refer to liquid manufacturer’s SDS)
Mechanical diaphragms should operate for approximately 2000+ hours under normal operating
conditions; however, the accumulation of foreign material or debris and abnormal operating condition
or simply age can cause failure. Failure can also occur as a result of hot pumping fluid or system over
pressure. Periodic diaphragm inspection and replacement are recommended.
6.2.1 Adjust the stroke control knob to “0” and disconnect the power source to the drive motor.
6.2.2 Relieve all system pressure from the piping system.
6.2.3 Take all precautions described under “Caution” to prevent environmental and personnel
exposure to hazardous materials.
6.2.4 Disconnect piping to the Liquid Head and drain any process liquid.
6.2.5 Place a pan underneath the pump head adaptor to catch any liquid leakage.
6.2.6 Remove all but two top Liquid Head bolt. Process fluid will leak out between the pump head
adaptor and Liquid Head as the bolts are loosened.
Page 13
12
6.2.7 Tilt the head and pour out any liquids retained by the check valves into a suitable container,
continue to follow safety precautions as appropriate.
6.2.8 Remove the final bolt and rinse or clean the Liquid Head with an appropriate material.
6.2.9 Inspect the diaphragm. The diaphragm must be replaced if it is cracked, separated, or
obviously damaged. Remove the diaphragm if necessary, by turning counter-clockwise.
6.2.10 To install a diaphragm, first ensure that the critical sealing areas of: diaphragm, Liquid Head,
and pump head adapter are clean and free of debris. Assemble the diaphragm with backup
plate (item #35). For MP7015-D3N, 5, 8 install spacer nut (item #50) onto the diaphragm
threads.
6.2.11 Thread the diaphragm (clockwise) completely on the push rod.
6.2.12 Install the liquid head, faceplate (for plastic heads), and bolts. Tighten bolts in an alternating
crossing pattern to ensure an even pressure on all bolts. Recommended torque is 12-13 ft-lb
for heads on MP7015-DN3, DN5, N8 pumps.

SECTION IV
SYMPTOMS
CAUSES
REMEDIES
1. Pump Motor Will Not
Operate.
A. Blown Fuse.
Check for short circuit or overload
B. Open thermal overload device in
starter.
Reset.
C. Low liquid level in tank (where low
level cut-off is used).
Fill tank.
D. Broken wire.
Locate and repair.
E. Low voltage.
Check for too light wiring.
2. Pump Does Not Deliver
Rated Capacity
A. Starved suction.
Look for blockage in suction line.
B. Leaky suction piping.
Replace suction piping with larger size.
Pressure test, repair or replace defective piping.
C. Excessive suction lift.
Rearrange equipment location to reduce suction lift.
D. Liquid too close to boiling point.
Lower temperature or increase suction pressure slightly.
E. Worn or dirty valves or seats, or
both
Clean or replace valve assembly.
F. Viscosity of liquid too high
1. Reduce viscosity by heating or other means
2. Increase size of suction piping
3. Increase suction pressure slightly
G. Low discharge pressure
A minimum discharge pressure of 25 psi is required to
insure proper capacity control
Repair or replace piping.
3. Pump delivers
erratically.
A. Leaky suction line.
Clean or replace valve assembly.
B. Worn or dirty valves or seats, or
both.
Increase backpressure.
C. Excessive excursion of ball valves
from seats (indicated by ball chatter).
Increase suction pressure.
D. Insufficient suction pressure
Raise tank level.
E. Liquid too close to boiling point,
Reduce temperature or raise suction pressure.
F Leaky system relief valve.
Repair or replace relief valve
4. Motor overheats thermal
overload activates,
A. Power supply does not match motor.
Check power supply against motor nameplate data.
B. Overload caused by operating pump
beyond rated capacity
Check operating pressure against pump manufacturer
data plate maximum rating
5. Noisy Operation
5.1. In Pump
A. Pump Valves.
Valves must move to open and close, and they will make
functioning.
5.2. In Gear Reducer
A. Pounding noise at high discharge
pressure
Fluid compressibility causes reversal of load on gears at
end of pressure stroke, Not considered detrimental.
MOTOR OPERATING CONDITIONS
7.0 The normal temperature rise for standard motors is 40°C above ambient temperature and, thus, it might appear
that the motor is operating at a higher than normal temperature. This situation is normal.
As a precaution against motor overheating, it is recommended that the pump be located where adequate
ventilation is available, It is also recommended that a MOTOR STARTER WITH THE PROPER OVERLOAD
PROTECTION BE SUPPLIED AS AN ADDITIONAL SAFETY DEVICE.

a clicking noise as they operate. These noises are
sometimes amplified by natural resonances in piping
system. They are usually indications of normal valve
