all correspondence regarding the unit. This will ensure
that the correct pump and/or parts are ordered in a
timely manner.
C. PARTS INVENTORY GUIDE. To avoid
unnecessary delays during maintenance of pump,
spare parts should be readily available for normal
service. Most matters can be handled with proper
usage of this manual. For every one to three pumps,
stock one spare set consisting of items listed in Table
5, Recommended Spare Parts. Part numbers
correspond to the drawings (figures 1 through 7)
found at the back of this manual.
A nameplate is attached to each pump. The data on
the nameplate should be recorded and filed for easy
reference. Nameplate data should be furnished to
Carver Pump Company or its representative when
ordering spare parts or requesting information.
D. PARTS ORDERING. Carver Pump Company

• Serial number of pump (located on
nameplate)
• Part name (refer to Table 6 and Table 7)
• Item number (refer to Table 6, Table 7,
and figures 1 through 7)
• Quantity of parts needed
Carver may ship an interchangeable part that is not
identical in appearance or symbol. This is done only if
the part has been improved. Examine the parts
carefully on receipt before calling the factory or a
company representative. Never return parts to the
factory without authorization from Carver Pump
Company.
If an impeller is ordered, specify diameter across
blade tips. Check to make sure diameter was NOT
trimmed further than diameter shown on Carver Pump
Company records.
If a motor/motor parts are ordered, specify the name
of the manufacturer and all other data found on the
driver nameplate.
E. SAFETY PRECUATIONS. This manual
contains descriptions and instructions, which are the
result of carefully conducted engineering and

II. INSPECTION AND STORAGE
A. INSPECTION UPON ARRIVAL. Upon
receipt of the shipment, check for missing or
damaged items. Unpack and inspect the pump,
driver assemblies, and individual parts. Carefully
inspect all boxes and packing material for loose
parts before discarding. Immediately report any
missing parts or damage incurred during
shipment to the factory and to the transportation
company. File your “damaged and/or lost in
shipment” claim with the carrier.
NOTE
The pump and equipment, as shipped from
Carver Pump Company, have appropriate
protection for short-term storage. If the
equipment is NOT immediately installed and
operated, store the equipment in a covered,
clean, dry, well-ventilated location, free from
vibrations, moisture, and rapid or wide
variations in temperature.
B. STORAGE OF PUMP. If the equipment is
NOT immediately installed and operated, Carver
Pump Company recommends rotating each shaft
several revolutions at least once every two weeks to
prevent flat spots on ball bearings.
Consider a unit to be in storage when any of the
following situations occur:
• The pump has been delivered to the job site and
is waiting to be installed.
• The pump has been installed but operation is
delayed pending completion of construction.
• There are long (30 days or more) periods
between operating cycles.
• The plant (or department) is shut down for
periods of longer than 30 days.
CAUTION
A pump, which is made of cast or ductile iron
that sits in extreme heat, high humidity, or
full or partially full water over 30 days will
rust and will most likely seize. If the pump
rusts and/or seizes, a complete overhaul and
repair may be necessary to refurbish the
pump.
Storage requirements vary depending on the
length of storage, the climatic environment,
and the equipment. For storage periods of
three months or longer, contact a
representative from Carver Pump Company
for specific instructions. Improper storage will
damage the equipment and will require nonwarranty restoration and/or non-warranty
product failures. Refer to Section VIII,
Service and Repair, for pump disassembly
and assembly procedures. When
disassembling the pump, replace and repair
rusted parts, as necessary.
NOTE
If the customer anticipates the
pump/equipment will be subject to an
extended period of storage after installation,
(for example, a unit used for seasonal
operation), contact a representative from
Carver Pump Company. If this is the case,
Carver will provide specific instructions for
the equipment during the extended period of
storage. In general, if a pump is to be shut
down for an extended period, the following
steps are recommended:
1. Shut down the pumping unit in
accordance with the operating
procedures outlined throughout this
manual.
2. Shut off system suction and discharge
valves.
3. Drain the unit.
4. Fill unit with mineral oil or suitable non-
corrosive protectant that is compatible
with the system.
5. Provide pump and motor with a
protective cover.

III. INSTALLATION.
V. OPERATION.
Skilled personnel should install the pump in
accordance with engineering standards. Faulty
installation will result in operating troubles and
premature wear of parts.
The pump and driver should be easily accessed with
enough headroom to perform periodic inspection and
maintenance. The pump should always be
submerged enough to prevent vortexes from forming,
which might allow air to enter the suction.
When pump is supplied with coupling, motor, and
baseplate, the complete set is assembled at Carver
Pump Company. After ascertaining that the unit has
suffered no damage in transit, one may install the
pumping unit. Proceed as follows:
1. Make sure the mounting surface is level.
Attach the base to the mounting surface.
Check that pump rotates freely.
CAUTION
Pipe strain will cause wear and/or damage to
parts.
2. Connect discharge piping. Extreme care
should be taken when connecting new piping
lines to be sure that no foreign matter such
as dirt, chips, tools, etc., is in the piping,
tank, or return piping as the debris will be
drawn into the pump and cause excessive
damage. Any debris caught in the pump
passageways will throw the pumping unit out
of balance.
3. Connect any necessary auxiliary piping and
gauge lines.
4. Since the pumping unit is shipped with
bearings packed, initial greasing will not be
necessary unless pumping unit has been in
storage for an extended period of time (refer
to section II).
5. Turn pump and motor shafts by hand to be
sure they rotate freely.
6. Connect wiring to motor. Due to high voltage
required to operate the pumping unit,
personnel working with the equipment
should be familiar with electrical safety
practices and modern methods of
resuscitation.
7. Connect electrical power supply to motor.
8. Open system valves.
IV. ALIGNMENT.
A flexible coupling connects the pump and motor.
The motor bracket aligns the pump and motor. No
further alignment is necessary.
A. PRESTART CAUTIONS.
1. Before starting or operating the pump, read
this entire manual, especially the following
instructions.
2. Before starting the pump, rotate shaft by
hand to assure all moving parts are free.
3. Before starting the pump, install closed
guards around all exposed rotating parts.
4. Observe all caution or danger tags attached
to the equipment.
5. Never run pump dry. Dry running may result
in pump seizure.
6. If excessive vibration or noise occurs during
operation, shut the pump down and consult a
Carver representative.
7. Use of a check valve in discharge piping is
recommended if there is a high volume of
reverse flow.
8. Check level in tank to see that the pump is
submerged in fluid.
B. STARTING THE PUMP. The pumping unit will
operate without operator intervention once system
valves have been adjusted to the specified pumping
conditions. The casing of the pump will be submerged
in the fluid being pumped, thus rendering it selfpriming. Proceed with operation as follows:
1. Make sure no one is working on the pumping
unit.
2. If the pumping unit has been idle for a period
of time, make sure unit is firmly attached to
its foundation.
3. Open valves to pressure gauges in system.
CAUTION
Check level of liquid in tank to be sure
casing is under liquid level.
4. Jog starter switch on motor to check
direction of rotation. Direction of rotation is
clockwise from fan end of motor.
5. Partially open discharge valve.
6. Start the pumping unit in accordance with
the directions on the electrical power supply.
7. Slowly adjust discharge valve to operating
condition required.
8. Pumping unit is now in full operation.
C. STOPPING THE PUMP. To stop the pump,
use the following process:
1. If pump is being stopped for overhaul, slowly
close the discharge valve. Otherwise leave
discharge valve set at condition.
2. Stop the pumping unit in accordance with the
directions on the electrical power supply.
3. If the pump is being stopped for overhaul,
close pressure gauge valves.
4
4. The pumping unit is now in the off position.
VI. MAINTENANCE.
Generally, the pump does not require continuous
supervision. Occasional visual checks are
recommended. Data should be recorded for each
pump to keep track of maintenance, which has been
performed and note operational problems. A pump
service record page is provided for this purpose in the
front matter of this manual.
Before disassembly/assembly, review Table A,
Torque Values to avoid equipment damage and injury
to personnel.

A. FIELD INSPECTION. Shutdown is not
required. Perform field inspection at regular intervals
and cover the following procedures:
1. Check and record the suction and discharge
pressures to establish differential head. It
should conform to the pump nameplate.
2. Check and record the power input and speed
of the driver.
3. Check and record pumping temperatures.
4. Check pump for quiet running.
B. STUFFING BOX. The stuffing box is equipped
with a throttle bushing which requires no regular
maintenance. The inside diameter of the throttle
bushing will increase with wear. The throttle bushing
should be inspected after pump disassembly. The
throttle bushing requires replacement if the inside
diameter is more than 0.020 inch out of round.
C. BEARING TEMPERATURE. Bearing
temperature should be monitored periodically. Normal
operating temperatures are 120 degrees F to 160
degrees F, depending on the ambient temperature.
Bearings may appear to run hot when pump is first
started. This is caused by the shaft seal, not the
bearing. When the seal is seated, temperature should
drop to normal.
Material
Steel (or
otherwise
noted)
316
Stainless
Steel
Check bearing temperature by placing a pyrometer
against the bearing frame while pump is running. A
temperature rise above 180 degrees F indicates
possible damage that requires checking. The most
common cause of high bearing temperatures is
overgreased bearings.
D. BEARING LUBRICATION. Lubrication
frequency depends on operating conditions. Normal
duty calls for relubrication every 1000 hours of
operation. Bearings are lubricated at Carver Pump
Company with Amoco Rykon Premium Grease No.
2EP, non-soap, polyurea thickened grease with a
drop point of 450 degrees F. This grease was
selected due to its suitability to extreme pressures
and its high temperature stability. Never mix greases
with differing properties.
Polyurea base greases are NOT compatible with
lithium or soda soap base greases. Therefore, the
type of grease added should not vary. However, if it is
necessary to change grease types, the bearings,
bearing frame, and bearing cap/cartridge should be
thoroughly cleaned and flushed with suitable solvent
to remove all traces of old grease. Disassemble
pump, remove shaft and bearings from bearing frame,
and follow these procedures:
1. Place bearings, bearing frame, and
bearing cap/cartridge in a wire or mesh
basket and suspend the basket in a light
mineral solvent. Allow it to soak,
preferably overnight.
2. After soaking and cleaning, the bearings,
bearing frame, and bearing cap/cartridge
should be rinsed in a clean, light mineral
solvent and agitated vigorously to remove all
loosened hard grease and dirt.
3. Dip bearings in clean, light oil and spin by
hand to determine that all foreign matter has
been removed.
4. After cleaning, repack bearings half full on
both sides with a good quality ball bearing
grease.
To relubricate bearings use the following procedure:
CAUTION
Overgreasing creates heat and is the cause
of many problems requiring repair. DO NOT
OVERGREASE.
1. Never relubricate pump bearings while unit is
running. If necessary, shut down pump
according to section V, paragraph C.
2. Remove plugs opposite grease fittings on
both ends of bearing frame.
