Installation, Operation, and Maintenance Manual
1. INTRODUCTION
This installation, operation, and maintenance manual is designed to help you achieve
the best performance and longest life from your Summit Pump models 2196, 2196LF, 2196-R, and 2796.
This pump is an open impeller, centrifugal model with end suction / top discharge.
The pump is designed for handling mild industrial corrosives.
If there are any questions regarding the pump or its application, which are not
covered in this manual or in other literature accompanying this unit, please contact
your Summit Pump distributor.
For information or technical assistance on the power source, contact the power source
manufacturer’s local dealer or representative.
SAFETY
The following message types are used in this manual to alert maintenance personnel
to procedures that require special attention for the protection and safety of both
equipment and personnel:
WARNING!
Failure to comply with the warnings in this
manual could result in personal injury or
death.
CAUTION!
Failure to comply with the cautions in this
manual could result in destruction of or
damage to equipment.
NOTE: Identifies a condition or
procedure which is essential to
proper equipment operation.
Failure to properly lift and move pump
could result in serious personal injury.
Immediately upon arrival, carefully inspect the pump for evidence of damage
during transit. Immediately report any damage to your Summit Pump Distributor.
STORING THE PUMP
Store the pump in a clean dry place. Do not remove piping connection covers.
Rotate the pump shaft by hand at least once per week to maintain a protective
film of oil or grease on the bearings. If you anticipate long-term storage, special
treatment is available for purchase from Summit Pump, Inc.
When choosing a location for the pump, select an area that provides easy access
for inspection and maintenance. Locate the pump as close as possible to the
source which will provide NPSH (Net Positive Suction Head) equal to or greater
than that required by the pump at any capacity over its expected operating range.
FOUNDATION
Use a foundation that is sufficient enough to support all points of the pump baseplate. Level and grout the base-plate per standard construction practices (see
ANSI/HI 1.4.2-1997).
PIPING CONNECTION – SUCTION / DISCHARGE
All piping must be independently supported and accurately aligned to the pump
suction and discharge flanges. Ideally, you should place a short length of flexible
or bellows type spool piece in the connections directly next to the pump flange.
WARNING!
Lock out driver power before beginning to
work on pump.
CAUTION!
Never use force to align piping to the
pump flanges.
CAUTION!
Never operate pump with suction valve
closed.
At a minimum, use suction pipe that is one size larger than the flange. Use an
eccentric reducer to meet the suction pipe with the pump. Mount the reducer flat
side up. Elbows must be a minimum of ten diameters from the suction flange.
CAUTION!
Never operate pump with discharge valve
closed.
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.
ALIGNMENT
The alignment at the pump and drive shaft is one of the most important
considerations in the pump installation.
WARNING!
Lock out pump driver. Failure to do so
could result in serious personal injury.
TO ALIGN THE PUMP
1. Use flexible spacer couplings to achieve proper alignment.
2. Check and adjust the parallel and angular alignment to within .005 inches
prior to connecting the coupling halves.
3. Jog the motor to check rotation. Its arrow should match up with the arrow on
the pump.
4. Install a coupling guard when the pump is aligned.
Pumps in hot service will need an alignment check at operating temperatures.
STUFFING BOX
Packed Box
Braided packing is supplied as standard equipment on all pumps. Install gland
bolt nuts finger-tight only. Adjust the gland bolt nuts during start-up to achieve
40-65 drops of leakage per minute. Specific packing type is dependent on pH,
temperature, etc. of the liquid being pumped.
Table 1
Pump Model
STO MTO LTO XLO
Packing Size 7/16 5/8
Number of Rings 5
Clean and cool pumpage may be used to lubricate the packing. If the pumpage is
not suitable, you must supply an external source of lubrication.
Do not allow packing to run dry. It must
be lubricated.
See ANSI/ASME B73.1 M-1984 for
proper seal flush plans.
Cartridge Mechanical Seal
WARNING!
Determine the effects that a failure of the
mechanical seal might have on the
environment and personnel and correct
conditions to prevent personal injury.
WARNING!
Only work on seal when the pump is
locked out and the seal is depressurized.
Refer to the Burgmann installation, operating, and maintenance instructions.
Failure to do so can result in environmental damage, personal injury, and seal
malfunction and / or seal failure. Pay particular attention to paragraphs 4.2, 4.3
and 4.4.
Start Up
Read, understand and follow the Burgmann Operation section 4.0, paragraphs 4.1
and 4.2
Storage, Assembly and Disassembly
Refer to the Burgmann Seal Storage assembly and disassembly sections 3.0, 3.1,
3.2, and 3.3, paying particular attention to the seal drawing included in the
instructions.
Type 1 Mechanical Seal
TO INSTALL TYPE 1 MECHANICAL SEAL
1. MTO, LTO, XLO Slide the stuffing box cover over the shaft/sleeve. Bolt the
cover (184) to the frame adapter(108).
STO Slide the 6” or 8” stuffing box cover (184) with adapter ring (108) over
shaft and bolt to bearing.
2. Mark / scribe the shaft at the face of the stuffing box.
4. Locate the installation reference dimension on the seal installation drawing.
Normally this is the dimension from the face of the stuffing box to the rear of
the seal.
5. Mark the shaft with a felt marker or marking tool at the dimension (i.e. 1/32”).
6. Lubricate the shaft with silicon grease or soapy water. Slide the seal onto the
shaft. Line up the face of the seal with your mark and secure with set screw.
PUMPS ARE SHIPPED WITH NO OIL IN
THE BEARING FRAME! Oil must be
installed before operating the pump.
Ball bearings are very sensitive to both over and under lubrication, both being
detrimental to bearing performance. Either case is detrimental to bearing
performance. Use a thermometer to determine overheating. Excessive overheating
will reduce bearing life.
The relationship between temperature and pumpage temperature is an indication of
performance. Table 2 indicates the relationship between these temperatures.
Table 2
Degrees Fahrenheit
Pumping liquid temperature
Approximate normal line bearing temperature
60° 200° 300°
115° 140° 160°
The information shown in Table 2 is based on a room temperature of 70°F. Maximum
bearing temperature is 175°F. The temperatures shown above have a tolerance of plus
15°F. It is necessary to flush water on the shaft for liquid temperatures above 250°F.
This can be done either through a flushing gland or the stuffing box seal cage.
Oil Lubrication
Use only high quality turbine oil with rust and oxidation inhibitors. Service
temperatures determine oil viscosity. See Table 3.
Use a 300 SSU viscosity at 100° F for applications where pumping temperatures are
below 200° F. At pumping temperatures above 350° F, use 470 SSU at 100° F with
optional cooler.

Grease Lubrication
Regrease grease lubricated bearings with NLG1 No. 2 consistency grease for
pumpage temperatures -60° F to 350° F. Grease is not recommended for temperatures
above 350° F. Regrease bearings every three months.

TO REGREASE LUBRICATED BEARINGS
1. Wipe dirt and foreign matter from the fittings.
2. Remove grease relief plugs from the bottom of the frame.
3. Fill grease through fittings until it comes out through the relief holes.
4. Reinstall grease relief plugs.
ROTATION
TO ROTATE THE PUMP
1. Lock out power to the pump driver.
2. Remove the coupling guard and coupling.
3. Momentarily restore power and energize the motor to determine rotation.
4. Confirm that motor rotation coincides with proper pump rotation. The proper
pump rotation is counterclockwise when facing the pump’s suction. Lock out
power to pump driver.
WARNING!
Operating the pump in the opposite
rotation may dislodge the impeller
causing severe damage to the impeller
and/or casing.
5. Reinstall the coupling and coupling guard.
6. Unlock power to pump driver.
IMPELLER CLEARANCE
WARNING!
Check impeller clearance prior to starting
pump. Setting may have changed during
transit.
WARNING!
Lock out power prior to working on pump.
Impeller clearance is the measurement between the impeller vanes and the surface of
the casing. This clearance is set at .015 inches during assembly, but may need to be
adjusted before initial startup. (See APPENDIX A for detailed procedures on setting
the impeller clearance.)
PRIMING
Prior to starting a centrifugal pump, it is imperative that you prime the pump by
flooding the suction piping and casing with fluid. Priming will occur when you open
the suction isolation valve and the packing sealing liquid valve.
CAUTION!
Do not operate the pump without liquid in
the casing.
START UP
TO START UP THE PUMP
1. Rotate the pump by hand; making sure that the rotating element is spinning freely.
2. Be sure the suction valve is open.
3. Partially close the discharge valve.
CAUTION!
Do not operate the pump with the
discharge valve closed for an extended
period of time.
