1. Introduction
1.1 General Description
Pulsafeeder’s Eclipse Standard/Eclipse Hypo Series pumps safely handle hazardous, highly corrosive, explosive
or toxic chemicals. Eclipse Hypo Series pumps were designed specifically for installation into Sodium
Hypochlorite applications. The Eclipse Standard/Eclipse Hypo Series pumps provide safe, leak-free service
because the magnetic coupling eliminates the need for traditional sealing methods, such as mechanical seals or
packing.
Eclipse Standard/Eclipse Hypo Series gear pumps mount to standard NEMA 56C, 143/145TC and 182/184TC
motors and IEC 63, 80, 100 and 112 B14 metric flanged (C-face) motors. This enables the pumps to be close
coupled, which provides greater assembled strength, complete isolated enclosure of all moving parts, and compact
design. This also eliminates the need for special base plate mounting, shaft couplings and guards, complicated
drives, and pump bearing lubrication and maintenance, while minimizing plant real estate for optimum pump
installation.
All Eclipse Standard/Eclipse Hypo Series pumps transmit rotational torque from the motor shaft to the pump shaft
by means of a magnetic drive coupling. The principle of operation of the magnetic drive coupling is that an
encapsulated driven magnet assembly is mounted on the end of the pump shaft. It is then contained by a closed
end containment shell or “containment can” which seals against the pump center housing with a static o-ring. A
drive magnet assembly attached to an electric motor shaft rotates around the containment can. When the drive
magnet assembly rotates, lines of magnetic flux or force cause the driven magnet assembly to rotate which in turn
causes the pump shaft to rotate.
All magnetic drive couplings are designed for satisfactory operation of the pump. The magnetic couplings have an
integral safety feature that allows them to “decouple” if the coupling torque limit is exceeded. This situation
might occur if foreign material were to jam the pump gears or if unusually high torque was developed on pump
start-up. Eclipse Standard/Eclipse Hypo Series pumps use permanent rare earth Neodymium Iron magnets that
can run decoupled without losing their magnetic strength provided magnet temperatures do not exceed 450
0
(232
C).
IF THE PUMP IS ALLOWED TO RUN FOR AN EXTENDED PERIOD OF TIME DECOUPLED, HIGH
TEMPERATURES COULD BE GENERATED THROUGH OPPOSING MAGNETIC FORCES THAT
ULTIMATELY WOULD CAUSE THE LOSS OF MAGNETIC STRENGTH
Eclipse Standard/Eclipse Hypo Series pumps feature continuous operation over wide temperature and pressure
variations, constant volume pulsation free flow, the ability to handle wide viscosity variations, and ease of
inspection and maintenance. Specific limitations are covered in this manual and summarized in Section 11,
Specifications.
To achieve successful operation and maximum life from your pump, make sure that the pump selection and
materials are compatible with the service and operating conditions of your application.

2. Equipment Inspection and Storage
Check all equipment for completeness and accuracy against the order and for any evidence of
shipping damage. Shortages or damage should be reported immediately to the freight carrier and
to your Pulsafeeder representative.
If the pump is not going to be installed immediately, the following steps should be taken:
Leave pump in original shipping carton.
Store indoors in a dry ambient atmosphere. Avoid temperature variations.
Leave all shipping plugs in place.
Contact the motor manufacturer for specific motor storage information.
These instructions should be read carefully by the personnel responsible for installation, operation and
maintenance of the equipment and kept in a convenient place for ready reference. It is recommended that a copy
of the order documents be kept with this manual as well as a written record of the pump model and serial number,
which is on the nametag attached to the pump.
Figure 1

3. Installation
Pump installation site should provide easy access for routine maintenance and protect the pump
from environmental elements and from leaks or drips from nearby process equipment. See
Figure 2 for typical installation diagram.
o Bolt the pump motor down firmly to mounting surface. Provide for air movement and circulation over electric
motor to enhance proper cooling.
o While looking at the pump from the magnetic drive end, the suction port is to the right when the pump drive
shaft rotates clockwise and is located below the ports. Reversing drive shaft rotation reverses flow and thus
suction and discharge ports. Since the Eclipse Standard/Eclipse Hypo series pumps can be installed both
vertically and horizontally, it is very important to verify proper motor rotation before final piping is
established.
o When installed horizontally, make sure the pump housing drain is on the bottom of the pump. If the pump is
installed with the drain facing upwards, the rotation of the motor will be incorrect and either needs to be
reversed or the pump orientation corrected. Reference the pump drawings in Section 18 of this manual for
drain location.
o Installation of vacuum or pressure gauges in the suction and discharge piping is recommended to properly
monitor system operation.
o Keep suction piping system short and straight to minimize friction loss to the pump. Make sure that the pump
will not run dry. Flooded suction or gravity fed fluid to pump inlet is generally preferred.
o Use only full-bore ball valves or gate valves in the suction piping. If suction strainers are used, size them to
minimize pressure drop and select those of a type that are easily cleaned and maintained.
o Arrange all suction piping and fittings to prevent formation of air pockets. Make sure all joints are airtight.
o Flush and blow out all suction lines prior to mating to pump. Use nipples and unions, for ease of maintenance.
Figure 2a – General Installation
3
o Do not force, bend, or spring either suction or discharge piping when mating up to the pump. Use supports or
hangers at intervals as required in an effort to compensate for piping strain due to vector forces and bending
forces. When necessary, install thermal expansion joints or accessories so minimal piping strain is placed
upon the pump.
o Check all bolts and nuts for tightness. Correct any conditions that could cause destructive vibration or
leakage.
o If start-up screens are used, be sure they do not clog and starve suction. Start up screens should be removed
prior to placing system into regular operation.
o If flexible suction lines are used, be sure their selection and installation will prevent wall collapse and thus a
starved suction condition.
o When taking suction from a tank or vessel, avoid entry of sludge or solids into suction line by placing suction
line inlet above maximum expected level of solids.
o Discharge line should be fitted with properly sized pressure relief valve to protect both pump and discharge
system. Pressure relief valve outlet should be piped back to the supply tank.
o When a by-pass system is used to control flow from the pump, the bypassed fluid should be piped back to the
suction vessel to prevent heat build-up due to recirculation cavitation. If it is absolutely necessary to pipe bypass back to the pump suction line, the point of entry should be at least one foot away from the suction inlet.
Provision for cooling should be made in the event of excessive heat buildup through fluid recirculation.
o Where pumped fluids may solidify, cry stallize, or precipitate, provisions should be made to thoroughly flush
pump and piping prior to periods of shutdown. Pay particular attention to proper flushing and draining of the
magnetic coupling area because this area may not completely self drain.
Figure 2b – Flow vs. Motor Rotation

4. Equipment Setup and Operation
Prior to operation, make sure all suction piping is air tight and clean. Check that electrical service to motor agrees
with nameplate ratings. Jog the motor to check rotation and for signs of binding. To check rotation, observe the
motor fan. Rewire motor if necessary. As noted in Section 3, Installation, Eclipse Standard/Eclipse Hypo Series
pumps are bi-directional, the direction of flow is determined by the direction of motor rotation.
ALTHOUGH THE ECLIPSE STANDARD/ECLIPSE HYPO SERIES PUMPS ARE DESIGNED WITH SOME RUN-
DRY CAPABILITY, IT IS NOT RECOMMENDED THAT ANY MAGNETICALLY DRIVEN PUMP BE RUN DRY. THIS
CONDITION CAN CAUSE SIGNIFICANT TEMPERATURE INCREASES RESULTING IN PREMATURE DAMAGE TO
WEAR SURFACES FROM LACK OF LUBRICATION AND
Pumping fluids containing abrasives should be avoided, as accelerated pump wear will result. Eclipse
Standard/Eclipse Hypo Series gear pumps are designed to handle clear fluids at viscosities up to 10,000 cps.
The pump is designed to self prime if fluid is supplied at the pump inlet. If foot valves are used, the valve should
be of the flapper type and sized to minimize friction loss.
If the pump operates near the boiling point of the pumped fluid, a recirculation loop can be set up between the
discharge and suction connections with provisions for flow control in the recirculation loop.
Power Monitors are strongly recommended for optimum protection of all magnetically driven pumps. Consult
factory for selection and support.
Do not operate the pump against a closed or blocked discharge. Doing so can cause the magnetic drive to
decouple. If decoupling occurs, stop the motor and restart after the obstruction has been cleared.
Operation against closed or blocked discharge can also result in casing pressure that exceeds the pump’s
published safe limits. This can result in damage to the casing parts and/or containment can.
As a safety precaution, a pressure relief valve by-pass system is highly recommended. Ideally, the pressure relief
valve is set for a low pressure at start-up to allow the pump to flood with liquid and evacuate air quickly. It can
then be re-adjusted to a setting appropriate to the application.
Hardware and fasteners can loosen during transportation and installation. All pump hardware should be checked
and verified tight before placing the pump in operation. Consult the table in Section 12 for the recommended
torque values for all pump hardware.
Pump hardware should be checked on a regular basis, especially if the pump is subject to temperature variations
or cycling that might cause it to loosen during operation.
Start pump with discharge and suction valves open and check for proper operation. Excessive noise or vibration
is an indication of harmful cavitation, which may be due to insufficient NPSH (Net Positive Suction Head).

5. Maintenance Overview
The timing for maintenance of the pump is established primarily on past performance. Each installation is
different. Therefore, regular inspections, and detailed maintenance records of past performance can be invaluable
for determining future preventative maintenance intervals. For motor maintenance instructions consult the motor
manufacturer.
BEFORE PERFORMING ANY MAINTENANCE REQUIRING PUMP DISASSEMBLY, BE SURE TO FLUSH AND
DRAIN PUMP THOROUGHLY WITH A NEUTRALIZING FLUID
EQUIPMENT WITH PROPER CARE
When changing a pump from one service to another, be sure to check that all wetted parts of the pump are
compatible with the fluid to be handled and that the motor is sufficiently sized for the application. If in doubt
contact your Pulsafeeder representative for assistance.
All magnetic drive couplings have a specific maximum torque limit. If this torque is exceeded
the drive will decouple. Operation in the decoupled mode should be avoided as high
temperatures could be generated.
.
. WEAR PROTECTIVE CLOTHING AND HANDLE
Whenever gear pumps exhibit reduced flow rates, inability to maintain pressures, noisy or otherwise abnormal
operation, first refer to the troubleshooting section at the end of this manual. If the problem cannot be resolved the
pump must be inspected for wear or damage. Eclipse Standard/Eclipse Hypo Series gear pumps can be easily
opened for cleaning and inspection without disturbing piping connections by removing the pump front housing
cover.
Where inspection shows wear, rebuilding the pump using a KOPKit is strongly recommended. Quite often,
original hydraulic performance can be restored by simply changing the KOPKit alone.
Magnets (both drive and driven) can attract small particles of debris during handling. Always visually
inspect the magnetic parts of the pump for cleanliness during re-assembly. Wipe carefully to remove
debris, particles, or other small parts without damaging the surface of the magnets.

5.1 Recommended Spares
KOPKits – The basic Eclipse Standard/Eclipse Hypo Series KOPKit consists of the following parts, which are
recommended as typical spare parts. The KOPKit provides an easy means to keep the right parts for your Eclipse
Standard/Eclipse Hypo Series pump close at hand.
Drive Gear and Shaft Assembly 1 each
Idler Gear and Shaft Assembly 1 each
Housing Liner 1 each
Bearings 2 each
O-Rings 3 or 4 each
The model number stamped on the pump nameplate identifies the pump type and other details. Refer to the model
number chart if you are unsure of exactly what type of pump you have, or when ordering parts or KOPKits.
Always refer to the full model and serial number in
Drawings and consolidated bill of materials for each size pump are included in this manual. Recommended spare
parts are identified on the consolidated bill of materials.
any correspondence with your Pulsafeeder representative.
5.2 Maintenance precautions for magnet-driven equipment:
Non-magnetic tools and non-magnetic work surfaces are recommended to perform any disassembly or
maintenance of the pump.
Do not wear a wristwatch in the vicinity of the drive or driven magnets, wristwatches may be damaged
by the transmission of magnetic flux.
The strong magnetic field will damage credit cards, security badges, or other magnetic data strips.
Keep them a safe distance from the magnets.
Take precautions in handling pump magnets if you have prosthetic devices, metal or medical inserts
installed in your body. Consult your physician for guidance in handling magnets.
Completely flush and drain pump prior to pump disassembly.
The exposed magnets on the drive magnet assembly are very fragile and will chip easily. Use extreme
care in handling them.
Take care to avoid magnetic particles or objects from attaching themselves to the drive magnets. It is
difficult to remove small particles, and larger objects could be attracted with enough force to break the
magnets.

2. Insert the containment can (item 19) and driven magnet (item 21) into the motor spool as shown. The driven
magnet is symmetrical and orientation does not matter.

4. Install o-rings (items 6, 15) into each side of the center housing (item 14) as shown. Some o-ring lubricant
may help keep the o-rings in place during assembly. Be sure both o-rings are fully seated into housing
grooves.
5. Place the center housing, with o-rings, onto the motor spool, aligning the port connections between any set of
motor spool bolt holes as shown. Add the retaining plates (item 32). Secure with eight bolts and washers
(items 16, 17). Tighten these bolts to the torque specified in Section 12. Always tighten fasteners in a
progressive “crisscross” pattern.

6. Insert a bearing (item 10) into center housing and slide to bottom of bore. Bearings are symmetrical and
orientation does not matter. Install the housing liner (item 11) and slide until it seats against the first bearing.
Install idler gear (item 12) into the top hole in bearing until the gear seats against the first bearing.
7. Install the drive gear (item 13), splined-end first, into the assembly until it bottoms out against the bearing.
The shaft may have to be rotated slightly to properly fit the splined-end into the drive magnet and mesh gear
teeth with the idler gear.
