i. Introduction to the Sunflo P-3000 Pump
The Sunflo P-3000 pump is a high pressure/high speed centrifugal pump which provides multi-stage
performance from a single-stage unit. The frame mounted configuration offers a greater degree of
performance diversity and added driver flexibility such as the use of standard electric motors, steam
turbines, and internal combustion. The close-coupled design incorporates the proven Sunflo design in an
integral pump and motor package. This configuration provides a compact lightweight unit that does not
utilize bedplates, couplings or belts. Installation is simplified and alignment of the pump and motor is not
necessary. Close-coupled pumps are ideal for OEM packages and other industrial applications where a
frame unit is not desired.
Common uses include pollution control, chemical, petrochemical, power system services, pulp and paper,
vehicle manufacturing, mining, food and beverage, and oil products.
ii. Safety Precautions

iii. Critical Startup Checklist
Know Your Machine
Before servicing and starting up the Sunflo P-3000 pump, carefully review the specification sheet, the
outline drawings, performance curves, and this instruction manual. It is important you become familiar
with the pump configuration before starting and operating the pump.
Driver Instructions
Carefully follow the installation and starting instructions provided by the manufacturer of the driver. This is
included in the final data package.
Auxiliaries
1. Check the utility connections.
2. Verify that the auxiliary piping conforms to Sundyne’s drawings.
3. Verify the connections of the switches, the instruments, and their settings.
4. Calibrate all measurement equipment (Flow meters, Current or Ampere meters, Pressure meters, etc.).
Environmental Control System
Install a system to control the environment of the seal, if required, and verify that Port 1 is properly
vented.
If required install overhead drain piping.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 7
Pressurized Fluid Loop:
Pressurize double seal buffer loop or external seal flush, if required, prior to admitting fluid into pump
casing.
Check Driver Rotation
Rotation must be in the same direction as the arrow stamped or cast on the pump casing.
Gearbox Servicing:
Where applicable, operate auxiliary lube pump to fill heat exchanger and filter. Add oil as necessary
through fill fitting until oil level stabilizes in sight glass. The gearbox alone requires approximately eight
U.S. quarts (7.5 liters).
Starting Pump
Start pump with suction valve completely open while throttling discharge valve, to bring pump to design
operating point.
Heat Exchanger
If a heat exchanger for the gearbox is installed, adjust the cooling flow to keep the temperature of the
gearbox sump at 120°-170°F (49°-77°C).
Check
Check total head, flow rate, and power consumption against pump specification sheet. Check that
specific gravity, viscosity and NPSH are in accordance with specification sheet. These conditions will
significantly alter performance of the pump.
Process Conditions
Do process conditions; suction pressure, suction temperature, discharge pressure, agree with
specification sheet information? Check with your Sunflo representative if you must test or run a different
fluid/specific gravity than shown on the specification sheet.
Auxiliary Lube Pump
If you have an auxiliary lubrication pump, unlock the electrical circuit and start it in the “hand” position.
Check for oil leaks and recheck the oil level.
Piping Connections
Are the following bolted/threaded connections tight:
a. Pump flange bolts?
b. Seal environment piping and port connections?
c. Cooling water connections to heat exchanger? (if applicable)
d. Gearbox oil drain plug?
e. Pump case drain plug?

Inspection
1. When you receive the Sunflo P-3000 Pump, check for any damage. If you find any, inform the carrier
and Sundyne Corporation promptly.
2. Use Outline drawings in the last section of final data package, and reference the Pump and Gearbox
bill of material to ensure that all auxiliary items are properly included.
3. Check the gear shaft carefully. Seal drag may cause it not to turn freely at first; this is normal. If the
gear shaft binds, it may be damaged, or may need adjusting.
Short-term Storage - 1 day to 6 months
1. If the pump is to be stored near strong chemicals or salt water, protect it immediately. To do this,
follow steps 5 through 10 from the long-term storage procedures below.
2. Protect the unit from moisture and dust.
3. Make sure that the factory’s shipping covers for the housing flanges and the seal ports are securely
in place.
4. Carefully follow the storage instructions provided by the manufacturer of the motor or turbine driver.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 9
Long-term Storage - 6 months or more
If you store the Sunflo P-3000 Pump for a long period of time, the following methods are very important.
If you require further instructions, please contact Sundyne Corporation at (303)-425-0800 USA and ask
for the Field Service Department.
1. Be sure the storage area is indoors and has: Humidity below 65%; and temperature range from 45°F
to 85°F (7°C to 29°C).
2. Do not allow contact of airborne chemicals with the internal components of the unit.
3. If the unit is being stored near strong chemicals or salt water, protect it immediately.
4. Protect the unit from moisture and dust.
5. Make sure that the factory’s shipping covers for housing flanges and seal ports are securely in place.
6. Prevent corrosion to the components of the gearbox and the fluid-end.
7. Use desiccant bags to absorb moisture.
8. Purge the internal components with an inert gas.
9. Flood component internals with oil.
10. After long-term storage, have an authorized Sundyne service engineer inspect all components and
supervise any necessary repair to be sure that they work properly. Any components not made by
Sundyne (except mechanical seals) must be inspected or replaced as determined by the
manufacturer’s authorized personnel, at the purchaser’s expense. Any Field Service work must be
clearly stated at the time of purchase to validate an Extended Warranty.
Because storage location and unknown factors at the site or storage are beyond our control,
Sundyne does not accept any liability for damage to the equipment during storage, nor do we
guarantee the quality of the equipment during and after the storage period. An Extended Warranty
will be null and void if the proper equipment preparation is not maintained.
Mounting
A. During pump installation, ensure that adequate surrounding space is available for inspection,
operation, and maintenance requirements.
B. The pump and driver for both the close-coupled and the frame mounted units should be bolted to a
concrete foundation or an adequately supported structure substantial enough to absorb any vibration
and to form a rigid support. If the pump and driver are mounted on a bedplate, the bedplate should
be mounted on a concrete foundation and grouted.
1. Choose a solid ground location and build the foundation form 3 inches larger overall than the
bedplate.
2. Use bedplate anchor bolts of the same size specified in the outline drawing. Provide pipe sleeves
with an I.D. 2.5 to 3.0 times the bolt diameter. Provide flat washers between the bolt head and pipe
sleeve to keep the bolt from slipping through the pipe sleeve.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 10
3. Bolts should be of sufficient length so that they will project at least one-fourth inch above the nuts
after allowing for bedplate, shim, and nut thickness. Locate the bolts accurately according to the
outline drawing.
4. Pour concrete and tamp or vibrate during the pouring process to ensure no hollow spot forms. This
is especially important around the anchor bolts. Do not allow any concrete to fall inside the pipe
sleeves.
5. Level off the concrete surface. Leave a rough finish to provide a good base for grout. Allow the
foundation to cure for one week before installing.
6. Hoist the bedplate above the foundation and lower into position over the anchor bolts. Anchor bolts
can be moved laterally in the hollow of pipe sleeve for ease of alignment with the holes in the
baseplate.
7. Using a precision level across the bedplate (front to rear and side to side), insert steel shims as
required next to each bolt until the bedplate is level in all directions. Secure the anchor bolt nuts
finger tight only.
8. Provide a wood dam around the base perimeter of the bedplate and thoroughly wet the top surface
of the foundation. The use of non-shrink grout is recommended. Grout should be of a consistency
to flow out under the bedplate against the wood dam. Grout should be puddled continuously as it is
poured to expel air and to completely fill the space under the bedplate. Fill to the level of the grout
hole.
9. Allow the grout to harden for at least 48 hours. Tighten the anchor bolts.
Figure 1
FRAMEMOUNT DRIVE UNIT INSTALLATION
A. Pumps supplied from the factory with a driver, base, and coupling are rough aligned prior to
shipment. However, stresses caused by lifting and shipment may cause minor distortion which will
alter the factory alignment. Check the coupling alignment after the baseplate has been leveled and
prior to grouting.
B. If the coupling alignment has been disturbed by improper leveling of the base-plate, correct prior to
grouting. After the base has been grouted and the piping connected, make a final pre-startup
alignment check. Additionally, a hot alignment check should be made once the pump has reached
normal operating temperature.
C. Coupling alignment should be verified only after the suction and discharge piping has been
connected.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 11
If a coupling is being used that was not supplied by Sundyne, it must be a flexible type,
vibration- damping coupling. Refer to the coupling manufacturer’s recommendations for
installation and alignment.
To prevent personnel injury, lock-out the starting switch on the driver.
D. Alignment of the pump and driver is vital to trouble-free mechanical operation. The following are
suggested steps to establish initial alignment of the unit using Sundyne stocked flexible couplings.
1. Clean all parts using a nonflammable solvent. Lightly coat the seal with grease and place on the
shafts before the mounting hubs.
2. Mount hubs on their respective shafts so the hub is flush with the end of its shaft. Tighten the set
screws when furnished.
3. Align the coupling. On the initial alignment, set the motor 0.003 to 0.004 inches (0.076 to
0.101 mm) higher than the pump to allow for thermal growth.
4. Tighten all hold down bolts on the pump and driver (and bedplate if used). Check the alignment
and realign if necessary.
FINAL ALIGNMENT
The motor shaft height should be equal to the pump input shaft height at operating temperature.
The final alignment should be re-checked after a week of operation
A. Final alignment can only be accomplished after the unit has been run under actual operating
conditions. The unit must be run for a sufficient period of time to bring the unit up to operating
temperature. After the warm up period has elapsed, stop the unit, disconnect the coupling, and check
the alignment. Repeat the alignment procedure and run the pump through another warm-up
procedure to verify the alignment.
B. Recheck the alignment after the pump has been running for about a week. This check must be made
immediately after the pump has been shut down and before it has a chance to cool.
Installing The Suction And Discharge Piping - Guidelines
A. Good installation practice dictates that there should be a minimum straight length of pipe on the
suction of the pump equal to ten (10) times the suction pipe diameter. This is to allow the liquid to
flow into the pump casing/impeller without turbulence. Furthermore, good installation practice
dictates the use of suction piping at least one or two sizes larger than the pump flange and reduction
of the pipe diameter at the pump flange. Use an eccentric reducer with the “Belly” side down. Do
NOT install with “Belly” side up. Never use suction piping of a smaller diameter than the pump suction
inlet.
B. Both the suction and discharge piping should have no unnecessary elbows, bends, and fittings as
they increase friction losses in the piping. The size of pipe and fittings should be selected carefully to
keep the friction losses as low as practical.
C. Suction and discharge block-and-bleed valve designs are recommended to isolate the pump during
shutdown and to drain the process piping when removal of the pump is necessary.
The rotation of the pump casing without a modification to the journal bearing
orientation will cause the pump to fail. Contact the factory or your authorized Sunflo
sales representative for assistance on how to modify the journal bearings.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 12
D. The pump casing can be rotating in increments of 90° to place the discharge connection in any of the
four positions: horizontal right or left and vertical up or down.
E. Do not rotate the seal housing. The seal ports must always be as shown in Figure 2.
Figure 2
F. Under no circumstances should the suction pipe be forced in order to align it to the pump suction
inlet. The flange bolts should slip into the aligned flange holes without straining the piping.
G. Gasket surfaces should be parallel and flange bolts should slip into the aligned flange holes without
straining the pipe to fit the pump.
H. Piping layouts should be designed to provide sufficient support and flexibility to minimize forces and
moments induced by the piping onto the pump.
I. All piping must be supported independently of the pump. Proper support for the suction and
discharge piping is essential in order to avoid pipe strain on the pipe casing.
J. The suction line should be clean and a temporary suction strainer of approximately 40 mesh should
be installed during initial startup to protect the impeller from damage by mill scale, welding slag, or
other foreign particles during initial startup.
K. Always provide a suction pressure gauge on all installations to monitor suction conditions. Install the
gauge as close as possible to the suction flange. When temporary suction strainers are used, ensure
that the gauges are installed on both sides of the strainer.
L. Always provide a discharge pressure gauge on all installations to monitor discharge conditions.
Install the gauge as close as possible to the discharge flange.
M. Check valves should be placed on all installations where back flow through the pump is possible. If a
check valve is installed in the discharge line, provisions should be made to vent the space between
the pump and the check valve or the pump may not prime.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 13
Auxiliary Piping and Seal Environment
A. Depending upon the pump seal arrangement and application, a seal environment control system may
be required. The pump seal environment must always be maintained as determined by the seal
arrangement. There are three different seal arrangements available for your Sunflo P-3000 pump:
The single seal, the double seal, and the tandem seal. It is important that the seal environment
control system piping be connected as shown in Figure 2 and that the seal drain port is always left
open.
B. For application data and available seal flush plans utilizing a process seal, please refer to Sunflo
Field Engineering Bulletin 40.2.58, “Sunflo Pump Seal Plans”. Contact your authorized Sunflo sales
representative if you do not have this bulletin.
If a seal flush system is not in use, then the seal flush port should be plugged to prevent
outside contamination of the seal cavity. The seal flush port is at the 12 o’clock position
as shown in Figure 2.
Regardless of what seal arrangement is being used, the process drain on the seal
housing must always remain open to atmosphere. Failure to leave the gearbox drain
port open will cause process fluid to accumulate in the seal housing and to eventually
leak past the gearbox seal into the gearbox oil sump.
Single Seal Flush System
C. A seal flush system utilizing the seal flush port is available for use with the single or tandem seal
arrangement. The seal flush must be cool, clean, and compatible with the process fluid and pump
materials of construction. When using an external seal flush, the seal must be flushed at 15 psi
(1.05 kg/cm2) above the seal cavity pressure and at a controlled rate of 2.0 gpm (0.4 m3/hr). Please
refer to Paragraph G of this section for details concerning seal cavity pressure rise. Seal cavity
pressure rise values are provided in Table 1.

02.10.02E, 6/2000 Visit our website at www.sundyne.com 14
Double Seal Liquid Buffer System
The buffer system must be in operation prior to flooding the pump suction. Failure to do
so will cause reverse pressurization of the in-board seal and may result in contamination
of the buffer system with the process fluid.
D. A liquid buffer system must be used with a double liquid seal arrangement to prevent process liquid
leakage out of the pump. The buffer must be cool, clean, and compatible with the process fluid and
pump materials of construction. The buffer is introduced into the “buffer in” port of the seal housing at
a pressure of 15 psi (1.05 kg/cm2) above the design seal cavity pressure rise. Please refer to
Paragraph G of this section for details concerning seal cavity pressure rise. Seal cavity pressure rise
values are provided in Table 1. A small portion of the buffer fluid flows across the inboard seal into the
process fluid and a small portion flows across the outboard seal and is vented from the drain port. A
buffer flow of 0.5 to 3 gpm (0.10 to 0.70 m3/hr) must be maintained through the buffer cavity to
properly lubricate and cool the seals. This flow should be regulated by a valve or orifice on the “buffer
out” port of the seal housing.
TANDEM SEAL LIQUID BUFFER SYSTEM
E. A liquid buffer system is used with tandem seal arrangement to cool and lubricate the outboard seal
and to contain process fluid leakage from the inboard seal. The buffer fluid must be cool, clean, and
compatible with the process fluid and pump materials of construction. The buffer liquid is introduced
into the “buffer in” port of the seal housing at atmospheric pressure and must maintain a flow of 0.5 to
3.0 gpm (0.10 to 0.70 m3/hr) through the buffer cavity to properly lubricate and cool the outboard
(secondary) seal.
PROCESS SEAL DRAINS
F. Piping may connect to the seal port drain. However, the piping should be arranged to prevent any
back pressure. Failure to prevent back pressure will cause a failure of the gearbox seal resulting in
the leakage of process fluid into the gearbox.
SEAL CAVITY PRESSURE RISE
G. Whenever a single seal with external flush, double, or tandem seal arrangement is used, the seal
cavity pressure rise must be known to determine the seal flush or buffer pressure. The area behind
the impeller, near the seal, is referred to as the seal cavity. Suction pressure plus the seal cavity
pressure rise plus a safety margin of 15 psi (1.05 kg/cm2) equals the required double seal buffer
pressure or the single seal flush pressure.
The required seal flush/buffer pressure may be determined for your pump model by using the values in
Table 1 and the method provided below:
1. Find the pump model that is applicable to your pump.
2. Determine the seal cavity pressure rise (based on water with a specific gravity of 1.0).
3. Multiply this seal cavity pressure rise value by the specific gravity of the process fluid.
4. Specify the seal flush/buffer pressure to equal the sum of the suction pressure, the specific
gravity corrected seal cavity pressure rise determined in Step G-3, and 15 psi (1.05 kg/cm2).

EXAMPLE:
Model: Sunflo P3-AJG
Suction Pressure: 19 psig
Seal Cavity Pressure Rise: 20 psig
(From Table 1)
Process Specific Gravity: 0.95
Required Seal Flush/Buffer Pressure
(RSFBP) = Suction Pressure + Seal Cavity Pressure Rise + 15 psig
RSFBP = 19 psig + (20 psig)(0.95) + 15 psig
RSFBP = 53 psig

Pre-Startup
Gearbox Oil Fill
Refer to Table 2 for lube oil system specifications.
Refer to Table 3 for gearbox lubricant specifications.
Overfilling the gearbox will cause excess foaming, increased power consumption, and oil leakage.
Make up oil can be added through the fill plug (P3-8) during operation.
A. Prior to initial startup and after any disassembly, the following oil fill procedure must be followed to
ensure proper priming of the high speed shaft journal bearings. Please refer to Figure 3.
B. Remove the plug (Item P3-214) on the lube oil manifold for use as an air vent.
C. Ensure that the gearbox oil sump drain plug is installed.
D. Remove the fill plug (Item P3-8) and fill the gearbox until the fluid level reaches the designated level
on the sight glass. Approximately 8 quarts (7.5 liters) are required.
E. Replace the fill plug and air vent plug.
F. Remove the oil filter, fill with oil, and reinstall.

Note: No additives are recommended.
In general, ISO VG 32 turbine oils or most synthetic oils will meet these specifications. The
properties of your oil should be verified by the oil manufacturer prior to use.
Dextron III type ATF is not recommended for use in Sunflo gearboxes. Problems with foaming may
occur and the additional additives compared to Dextron II could compromise the mechanical
integrity and reliability of your Sunflo pump.
Startup
Perform the following steps to start your Sunflo pump.
A. Review the pump specification sheet noting design parameters and possible seal system
requirements.
B. Check to ensure that the driver has been serviced per the instructions supplied by the driver
manufacturer.
C. Check to ensure that the screen has been installed in the temporary suction strainer.
D. If a buffer fluid or external seal flush is required, ensure that this system is pressurized prior to
flooding the suction. Failure to pressurize the buffer system will allow the process fluid to
contaminate the buffer fluid and may also allow contaminants in the process stream to damage the
seal face.
