INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
SUMMIT PUMP MODEL 2996 IN-LINE 1
2 INTRODUCTION
This installation, operation, and maintenance manual is designed to help you achieve the best
performance and longest life from your Summit Pump. This pump is an open impeller centrifugal
type with an in-line suction/discharge. The pump is designed for handling mild industrial corrosives.
This pump is a centrifugal pump which generates pressure, not flow. Velocity imparted to the casing
from the impeller tip is converted from velocity energy to pressure energy; flow is a byproduct of the
differential pressure.
Fluid from the suction eye is dispersed through the impeller in the volume between the impeller
vanes. Fluid leaves the impeller at approximately the same speed as the vane tip and collides with the
casing wall; the velocity energy is converted to pressure energy. If allowed, the fluid will leave the
discharge port towards a lower pressure.
If there are any questions regarding this pump or its application, which are not covered in this
manual, please contact your local Summit Pump, Inc. Distributor.
For information or technical assistance on the driver service, contact the driver manufacturer’s local
dealer or representative.

Removal of this tag is highly discouraged. The
manufacturer and distributor use this information to
trace the origins of the pump and to help with
troubleshooting.
4.2 Model & Size
Summit 2996 pumps are primarily defined by the pump model and size. The size is made up of
three identifiers, “Discharge port size” x “Suction port size” – “Approximate maximum impeller
diameter”
Example: 2996 1.5x3-8
In this example, the pump is a 2996 with a 1.5 inch discharge and a 3 inch suction. The
approximate maximum impeller diameter is 8 inches.
4.3 Imp Dia
This field identifies the exact trim diameter of the impeller as it was sent from the manufacturer.
4.4 Max Dia
This is the maximum diameter of the impeller for this pump. This information is also found as
the largest trim size on the catalog pump performance curve for the pump.
4.5 ANSI NO
Model 2996 has pump sizes that conform to ASME B73.2 standard. Pump sizes that comply with
this standard will have the Dimension Designation as defined in ASME B73.2 printed in this
field. If the field is left blank the pump is not defined by this standard.

company as soon as possible.
5.2 STORING THE PUMP
5.2.1 Temporary
Temporary storage: less than six months.
1. Flush the pump with clean water. If pumped product is water reactive, remove the suction
and discharge line after draining the pump, and with compressed air blow all liquid from
cavity. Lightly cover all internal metal parts with oil and replace the suction and
discharge lines if needed.
2. Store pump in a clean, dry place, free from extreme swings in temperature and humidity.
3. Cover with a protective covering to reduce dust contamination.
4. Rotate the shaft once a week to protect the bearings from brinelling the raceway and/or
balls.
5.2.2 Long Term
Long Term Storage: more than six months.
1. Follow temporary storage guidelines 1-4 in section 5.2.1.

6 INSTALLATION
6.1 GENERAL
Summit Pumps are assembled at the factory, the pumps are ready to be installed. Make sure seals
have been set and all auxiliary piping is attached if applicable. Set impeller clearance and follow all
instruction tags on the pump. Ensure all fluid properties and application requirements have been
considered and relayed to manufacturer and/or distributor. Suction piping should be as short and
direct as possible.
6.2 LOCATION
If the pump is going to have a water flush, it should be located as close as possible to the supply of
water. Suction and discharge lines should follow standards provided in ANSI/HI 9.6.6
Rotodynamic Pump for Pump Piping and ANSI/HI 9.8 Pump Intake Design. Location
considerations are easy access for inspection, maintenance and ample overhead space for lifting
with crane or hoist. Pump should be located as close as possible to fluid source.
6.3 PUMP SUPPORT
2996 will be supported by the piping. Piping support must be located close to the pump and
designed to support the weight of the piping, pump and motor assembly. Supports under the pump
are not required but recommended. Installation design must be reviewed for pump supports.
Use a foundation that is sufficient to support all points of the pump and motor assembly as well as
the piping and piping supports.
6.4 PIPING
Piping, suction and discharge, should follow ANSI/HI 9.6.6 Rotodynamic Pump for Pump Piping
and ANSI/HI 9.8 Pump Intake Design. Ensure piping is aligned as to eliminate moments and forces
generated when connected to pump. Arrange piping to allow for pump flushing before pump unit is
removed, especially when product is hazardous.
DANGER
Lock out driver power before beginning to
work on pump.
CAUTION
Never operate pump with suction valve
closed
CAUTION
Never use force to align piping to the pump
flanges

INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
SUMMIT PUMP MODEL 2996 IN-LINE 9
6.4.1 Suction Piping
Use suction pipe that is the same size or one size larger than the flange. If needed use an eccentric
reducer to meet the suction pipe with the pump. Mount the reducer flat side up. Use non-obstructed
straight pipe, as a guideline, for minimum of 5 pipe diameters (10 diameters recommended) from
the pump suction flange.
6.4.2 Discharge Piping
The discharge piping should include isolation and check valves. The check valve prevents the
pump from rotating backward. Place the check valve between the pump and isolation valve. The
isolation valve is used for priming, starting, and shutting down the system. If you use pipe diameter
increasers, place them between the pump and the check valve.
6.4.3 Piping Inspection
Rotate the pump shaft after all piping and auxiliary piping is installed and attached to the pump.
Listen for rubbing and feel for any indication of binding. This is a very robust check, remove
piping and ensure alignment of piping if rubbing or binding occurs. If no obvious rubbing or
binding is present, shaft alignment should be checked at this point.
6.5 SHAFT ALIGNMENT
Alignment of the pump shaft (122) to the motor shaft is normally acceptable using the machine
fits of the pump build and C-face fit of the motor and motor support (240). It is possible to build a
2996 with a standard 2196 power end (grease lubed) of which standard shaft alignment practices
must take place as the 2196 is not machined to fit into the motor support.
If a shaft alignment of 0.002” T.I.R or less is required by the end user follow the procedure to fine
tune the shaft alignment. This procedure uses the casing bolts and a range of +/-10% of the
recommended torque setting to adjust the alignment of the pump shaft.
6.5.1 Fine Tune Shaft Alignment
1. Ensure all machined surfaces are free from debris and damage. Even the smallest particle of
dirt will affect the alignment.
2. Reset the pump components and motor my loosening the motor, motor support (240) and
casing (100). Loosen the bolts just enough to allow some movement with the components.
3. Increase the impeller clearance by using the jack bolts (370D) on the bearing housing (134). A
quarter turn is all that is needed to provide the extra space between the impeller (101) and
casing (100) to avoid any contact issues during alignment.
4. Tighten and torque down motor bolts (370U) in a four-point star pattern. Use Table 13-2 on
page 36 for recommended torque values.
5. Tighten and torque down motor support bolts (372J) to 90% of their recommended torque
value.

INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
10 SUMMIT PUMP MODEL 2996 IN-LINE
6. Tighten casing bolts (370) in a star pattern
to 60% of their recommended torque value.
Go around the star pattern again and torque
to 90% of the recommended torque value.
Recommended casing bolt torque values
can be found in Table 13-1 on page 36.
7. Connect a dial indicator to the coupling end
of the pump shaft (122) as shown in Figure
6-1. Mark the pump shaft (122) in one
location to indicate the position to take
measurements.
8. Rotate the motor and pump shaft together
taking dial indicator measurements every
90 degrees for a total of four measurements.
9. Increase torque on casing bolts (370) incrementally to adjust the alignment of the pump shaft
with the motor shaft. Do not exceed 110% of the recommended torque value. After each series
of casing bolt (370) adjustments repeat step 5 and 8 until desired shaft alignment is reached.
10. Reset the impeller clearance to the stated clearance in Table 7-3 on page 10.
6.6 SEALING
6.6.1 Packed Box
NOTICE
Packing must be lubricated. See
ANSI/ASME B73.2 M-2016
Braided packing is optional on all pumps. Install gland bolt nuts (355) finger-tight only. Adjust
the gland bolt nuts (355) during operation to achieve 40-65 drops of leakage per minute. No not
run packing dry. Specific packing type is dependent on pH, temperature, etc. of the liquid being
pumped. If process fluid is dirty, a clean liquid flush to the lantern ring (105) must be supplied to
keep packing (106) clean and lubricated.
Pumps are shipped with packing consisting of a total of 5 rings of packing (106) and one lantern
ring (105). Packing (106) is installed with ring ends 90 degrees apart starting with three packing
rings, followed by the lantern ring and two more packing rings moving inboard to outboard.

6.6.2 Cartridge Mechanical Seal
WARNING
Failure of the mechanical seal could
result in serious injury and environmental
damage.
DANGER
Lock out driver power and make sure seal
is depressurized before beginning work
Unless specified otherwise, pumps are shipped with mechanical seals installed in the pump. They
will NOT be set and will have clips still installed to separate the seal faces during shipment. The
seal must have clips removed and the seal must be set before operation.
Refer to the manufacturer’s installation, operating, and maintenance instructions. Failure to do so
can result in environmental damage, personal injury, and seal malfunction and/or seal failure. As a
guideline, Figure 6-3, Figure 6-2 and Figure 6-4 show inspections that should be done prior to
installing the seal.
Mechanical seals must not run dry or operate in dirty
liquids. Connect flush, quench, barrier/buffer or cooling
fluids as required.
6.6.3 Type 1 Mechanical Seal
Pumps are shipped with type 1 mechanical seals installed
in the pump. Type 1 seals are set and ready for operation.
Installing a type 1 mechanical seal requires a reference
dimension from the seal manufacture. This reference
dimension is usually from the shoulder of the sleeve or
solid shaft to the nearest face of the set collar of the seal.

7 OPERATION
7.1 CHECKING ROTATION
The pump can only operate clockwise rotation when viewed from the motor. If the pump has been
accidently operated in a counter-clockwise rotation remove the pump from the casing and ensure
damage has not occurred. (As a general note, the pump will produce about half the expected head
at an given flow if the pump is rotating counter-clockwise.)
DANGER
Lock out power to avoid personal injury or
death.
1. Lockout power to drive.
2. Remove the pump from the motor.
3. Unlock power to motor.
4. Clear personnel from immediate area, jog motor just enough to determine direction of
rotation.
5. If the motor is rotating in the wrong direction the electrical wiring will need to be adjusted
by qualified personnel. Then repeat Step 4 and 5.
6. Once rotation is in the desired direction, lockout motor and reattach pump to motor.
7. Check clearances connect piping to pump and check alignments.
8. Unlock motor.
7.2 FIRST RUN CHECK
Several items need to be checked before you put your pump into service. Each of the following
items needs to be addressed to make certain that your equipment is correctly installed.
1. Ensure all plugs, seals or packing is installed correctly.
2. Impeller clearance is set for the application. Refer to Section 7.4 on page 17
3. Proper alignment of pump.
4. All electrical connections.
5. All instruments and gauges should be in working order.
6. Correct pump rotation is checked.
7. Open the suction valve and crack open the discharge valve slightly. There must be some
resistance when starting and evacuate any air in the line.
WARNING

internals.
7.2.1 Start Up
1. Crack open the discharge valve to allow flow, yet still give the pump resistance.
2. Before operating the pump, it must be filled with liquid. If in a flooded suction, opening the
suction valve will fill the pump piping. The pump can also be primed by removing the
discharge piping and filling the pump with the pumped liquid or water. (Only use water if it
will not contaminate the pumping liquid.).
3. Ensure the motor rotation is clockwise when viewed from the top of the motor looking
towards the pump.
4. Ensure all plugs, gauges, seals are installed and any seal clips are removed.
5. Start the pump.
CAUTION
Immediately monitor flow and pressure
gauges. STOP pump if not primed.
7.2.2 Shut Down
1. If possible, flush the pump with clean water. (Only use water if it will not contaminate the
pumping liquid.)
2. Slowly close the discharge valve to minimum flow of the pump.
3. Shut down the motor.
4. Close both the discharge and suction valves after pump as come to a complete stop.
5. Lockout power to the motor.
