INTRODUCTION & SAFETY

Equipment and Safety Precautions

Sundyne Corporation manufactures centrifugal pumps to exacting International Quality Management System Standards (ISO 9001) as certified and audited by Lloyd’s Register Quality Assurance Limited. Genuine parts and accessories are specifically designed and tested for use with these products to ensure continued product quality and performance. Sundyne cannot test all parts and accessories sourced from other vendors; incorrect design and/or fabrication of such parts and accessories may adversely affect the performance and safety features of these products. Failure to properly select, install or use authorized Sundyne pump parts and accessories is considered misuse and damage or failure caused by misuse is not covered by Sundyne’s warranty. Additionally, modification of Sundyne products or removal of original components may impair the safety of these products and their effective operation.

Note: Sundyne pumps may handle

hazardous, flammable, and/or toxic fluids. Proper personal protective equipment should be worn. Precautions must be taken to prevent physical injury. Pumpage must be handled and disposed of in accordance with applicable environmental regulations.

Note: Safety procedures must be applied

prior to any installation, maintenance, or repair of a Sundyne pump. Failure to follow safety precautions may lead to injury!

Wearing Personal Protective Equipment To ensure safety, protective equipment must be worn at all times when installing, performing maintenance, or repairing equipment. The following safety recommendations must be adhered to for optimum safety:

• Safety glasses, with the minimum requirement of side shields, must be worn at all times.

• Steel-toed shoes must be worn when lifting equipment greater than 15 pounds (7 kg) or if pallet jacks or forklifts are operated.

• Hearing protection is strongly recommended at all times when noise levels exceed 85 dB during an eight (8.0) hour period.

Note: Chemical resistant gloves must be used

if chemicals are utilized (refer to Using Chemicals for additional information).

Note: A dust mask respirator must be worn if

chemicals have warning labels regarding fumes, dust, or mists.

When using more than one piece of protective equipment, consider their compatibility. For example, safety glasses will not interfere with hearing protection equipment. Be sure to clean all pieces of personal protective equipment immediately after each use.

Using Forklifts Any persons operating a forklift must have an active recognized operator license.

Note: Before initializing forklift operation,

verify that the lift is in a safe operating position.

Ensuring Electrical Safety All electrical sources must be powered-off before installation, service, or repair of equipment occurs.

Note: Sundyne recommends that a Lock-

out/Tag-out program be followed prior to altering the equipment. Locks or tags must be provided to warn employees that equipment is temporarily unavailable.

Once all work has been completed, the person installing the lock or tag must remove it according to company procedure.

Testing Equipment Prior to performing a test on newly installed, maintained, or repaired equipment; all personnel in the immediate area must be warned.

Note: Follow company procedures prior to

equipment testing at all times.

Using Chemicals Any chemicals to be used must be accompanied by a relevant material safety data sheet (MSDS), in accordance with government legislation. If applicable, use chemical proof gloves.

Note: An eye wash station (or equivalent)

should be available in the event of injury. If any hazardous or flammable chemicals pass through the equipment, a complete decontamination of the equipment is required.

Protection from Falling Fall protection and associated preventative measures are required when working on equipment located six feet or higher from the ground.

Note: Follow company fall prevention

procedures prior to working on equipment.

Preventative Machine Guards Preventative guards must remain in place on all equipment.

Note: Only remove the guards while

performing maintenance or repair.

Replace the guards immediately after working on the equipment and prior to start up.

INTRODUCTION This manual presents installation, servicing, troubleshooting, maintenance and spare parts information for the latest configuration of Sundyne LMV-333. Parenthetical numbers included in the text correspond to item numbers on the illustrated figures. The item number of a part is based on the part’s function, and the correct spare part can be ordered for any pump by referencing the item number and serial number.

Information that may be required regarding performance, alterations, or detailed technical data which is not included herein, may be found in the specification sheet and parts list accompanying the unit, or may be obtained from your Sundyne Corporation representative. Reference the pump serial number in any communication with the factory. Custom-made auxiliary equipment cannot be shown in this manual. Refer to the outline drawing for specifics.

I. INSTALLATION 1. INSPECTION

Check visually for shipping damage. If damage is found, notify the carrier and Sundyne Corporation promptly.

2. STORAGE If the pump is not to be installed immediately: A. Protect from exposure to moisture and dust. B. Shipping cover and pipe plugs must be kept

in place. C. Consult your Sundyne representative if

storage time will exceed six months. D. For driver storage (motor or turbine), observe

manufacturer’s instructions. 3. LONG-TERM STORAGE

Certain long-term considerations should be met for any Sundyne pump which will not be operating for a period of time exceeding six months from date of factory shipment. This action will insure minimum corrosion damage to the gearbox and fluid-end components. Because of storage location and other unknown site factors beyond our control, Sundyne Corporation will not accept any liability for damage to the equipment during the storage period, nor does Sundyne Corporation guarantee the condition of the equipment during and after the storage period. To insure the original quality of the Sundyne pump prior to commissioning after storage, all components must be inspected by an authorized Sundyne service engineer. Any components not of Sundyne manufacture (except mechanical seals) must be inspected by that particular

submanufacturer’s authorized service personnel. The cost of such service personnel and any component replacement will be at the purchaser’s expense. Factors which affect the quality of an uninstalled Sundyne pump are the humidity/temperature and the chemicals in the atmosphere surrounding the equipment. The method employed for long-term storage should prevent the humidity/temperature and airborne chemicals from making contact with the internal components of the equipment. When the equipment is to be stored in strong chemical environments or near salt water, protection should be executed immediately upon receipt of the equipment. Following is the Sundyne preferred list of recommended long-term storage procedures: A. Indoor, climate controlled building (maintains

constant temperature and humidity). B. Inert gas purging of the component internals. C. Oil flooding of component internals. D. Desiccant bags.

Because long-term storage of equipment is of a highly critical nature, it is recommended that Sundyne be contacted to provide more details on the above procedures. 4. SUCTION AND DISCHARGE PIPING A. Suction piping should have as few restrictions

as possible to avoid NPSH losses and to provide the NPSH required as listed on the spec sheet.

Page 8: Instruction and Operation Manual - Sundyne and Operation Manual ... Pump Mechanical Seal Troubleshooting ... of Sundyne manufacture (except mechanical seals)

2

B. A suction strainer is recommended to protect the impeller from damage by mill scale, weld slag, or other foreign particles. A cone shaped strainer with ¼ inch (6.35 mm) holes is preferred. For initial start-up, a screen with mesh openings of .060 inch (1.524 mm) can be attached over the cone then removed after the system is clean. Use caution not to run the pump with a clogged strainer.

C. A discharge check valve should be used if reverse flow is likely during shutdown.

Never leave the suction block valve closed with the discharge block valve open.

5. SEAL ENVIRONMENTAL CONTROL SYSTEM Depending upon the pump seal arrangement and application, a seal environmental control system may be required. A. Refer to the specification sheet and outline

drawing to determine the seal arrangement and system requirements.

B. Many sealing options exist. Consult your Sundyne representative if alternatives are required.

6. GEARBOX HEAT EXCHANGER A. The standard heat exchanger is a shell and

tube water-cooled type. B. Cool water should be provided at 150 psig

(11 kg/cm2) maximum pressure. Coolant flow should be controlled to maintain a gearbox sump temperature between 140°F to 200°F (60°C to 93°C).

C. The optional air-cooled heat exchanger should be controlled to maintain the same gearbox sump temperature as above.

NOTE Refer to the outline drawing for heat exchanger mounting configuration. The assembly should not be rearranged without consulting the factory. THE HEAT EXCHANGER IS NEVER MOUNTED HIGHER THAN THE GEARBOX MANIFOLD.

D. For more detail refer to section “II. LUBE SYSTEM”.

7. DRIVER AND COUPLING Drivers are normally shipped separately from the gearbox and compressor. When a splined

interconnecting shaft is supplied, this shaft must be lubricated at each end with one tube (5cc) of anti-fretting compound (Sundyne Part Number MP01AA10). Also available are solid shaft drivers coupled to the gearbox with a flexible coupling. See Section “IV. SERVICING” for further coupling information. Drivers are to be installed and maintained in accordance with the manufacturer’s instructions.

8. LOCATION The installation should provide clearance on either side for removal and service. Overhead clearance must be provided for lifting out the driver or gearbox assembly.

9. MOUNTING The vertical motor stand should be mounted on a rigid concrete foundation, secured in position by 7/8-inch diameter bolts and grouted in place. The bolts should be installed in the foundation as shown on the outline drawing. The length of the bolts should be sufficient to extend at least ¼ inch above the nut. The base mounting pads should be leveled prior to grouting. Grout must be allowed to set for at least 48 hours before tightening foundation bolts. Customer shall provide a 4” x 4” x ¼” thick steel plate under each leveling screw.

10. ALIGNMENT A. Spline driven units do not require alignment. B. For units driven by flexible couplings, refer

to section “IV. SERVICING”.

11. PIPING CONNECTIONS A. Drain lines from the seal housing ports may

be necessary. Refer to the outline drawing for port usage.

B. Port number 1 (shown in Figure 4) must always be open to atmosphere or piped to safety drain or flare with a backpressure not exceeding 7 psi (0.49 kg/cm2).

12. DIFFUSER CAVITY VENT The diffuser cavity vent must be open to atmosphere or to a safety drain with no back pressure. See figure “Wet End Components” for location.

Note: Process fluid may accumulate causing a

potentially hazardous situation if the diffuser cavity is not properly vented.

III. STARTING A. START-UP PROCEDURES

Perform the following tasks to start the Sundyne pump. 1. Run-in or pump: If the pump is to be run

under conditions which are considerably different from those conditions listed on the spec sheet (such as a change in specific gravity, suction pressure, flow rate, etc.) the factory should be consulted to insure that the run-in conditions are compatible with the pump.

2. Check to insure that the driver has been serviced according to instructions provided by the driver manufacturer.

Check driver rotation prior to start. Driver rotation must be in the direction of cast-in arrow on the pump case. Rotation in reverse direction will result in bearing damage.

3. Auxiliaries: Check utility connections; verify that auxiliary piping is per Sundyne drawings; verify switch and instrument connections and set points; calibrate flow instruments and other transmitters.

4. Flushing screens should be installed in all field assembled piping connections.

5. Check the spec sheet and outline drawings for seal environment requirements. Be sure housing port piping is properly connected. If double seals are used, buffer fluid must be pressurized before suction pressure is applied to the pump.

6. Check to ensure the diffuser cavity vent is

vented. 7. Remove the gearbox fill-vent plug and the

filter breather cap from the fill fitting on the gearbox. Fill the reservoir with clean lubricating oil (see section “IV. SERVICING”, Figure 3 for oil specifications) until the fluid level is at the top of the black circle in the sight glass. Lube system capacity will vary with the heat exchanger and piping configuration. The gearbox holds approximately 7 quarts (6.6 liters). Replace the filter breather cap on the fill opening fitting and replace the fill-vent plug. If a

prelube pump is not used, remove the plug on top of the oil filter manifold and fill the oil filter and heat exchanger with oil.

8. If an auxiliary lube pump is installed, operate the pump to fill the heat exchanger and filter. Add oil as necessary through the fill fitting until the oil level stabilizes in the site glass.

9. If no auxiliary lube pump is used, jog the main driver until oil pressure is observed on the pressure gauge. This should occur by the second or third jog of 2-3 seconds duration.

Never start the pump against a closed discharge valve. Always check to insure that the discharge valve is partially open.

10. If an auxiliary lube system is installed, it should be used in the following manner: A. At the initial start-up or after changing

the lube oil, run the pump for several minutes to work any trapped air out of the piping. Adjust the relief valve on the auxiliary pump to provide 25 psi (1.76 kg/cm2) oil pressure to the system.

B. The auxiliary system is intended to provide oil before starting the main driver. It should run for a minimum of 30 seconds maintaining an oil pressure of 5 psig before the main driver is started. Pressure switches and time delays can be used if automatic start sequences are desired.

C. After the start of the main driver, oil pressure will be supplied by the main lube pump inside the gearbox. An increase in oil pressure should be observed. Shut down the auxiliary pump within two minutes of the main driver start.

11. Adjust the heat exchanger cooling flow to regulate the gearbox sump temperature between 140° and 200°F ( 60° and 93°C). Approximately one hour may be required to stabilize the temperature.

B. PUMP CONTROL DURING START-UP Refer to Section “V. OPERATION AND CONTROL” for more detail. 1. SINGLE UNITS

A. Start pump with the suction valve open while throttling the discharge valve to bring the pump to the design flow operating point.

B. If the process fluid is near boiling, a seal cavity vent back to the supply vessel may have to be opened to fill the pump with liquid.

2. PARALLEL OPERATION Check valves must be placed in the discharge piping of each pump to prevent back-flow. It is advantageous to install separate bypass loops around each pump for additional operational flexibility. A. Start first unit as described above for

single units. B. Start second unit on bypass and maintain

flow. Open discharge valve on second unit and maintain the design flow of both units. It is preferable that the units not operate at their peak head capability.

C. Separate flow controls on each pump are recommended and provide a lower minimum flow range than can be achieved by pressure control.

C. CRITICAL START-UP CHECK LIST

1. KNOW YOUR MACHINE Prior to servicing and start-up of the Sundyne pump, carefully review the specification sheet, outline drawing, performance curves, and the instruction manual. It is important you become familiar with the pump configuration before starting and operating the pump.

2. DRIVER INSTRUCTIONS Follow installation and starting instructions of the driver manufacturer.

3. GEARBOX SERVICING Fill gearbox to the top of the black circle in the sight glass with lube oil which conforms to the specifications in Figure 3. Operate auxiliary lube pump to fill heat exchanger and filter. Add oil as necessary, approximately seven U. S. quarts (6.6 liters) through fill fitting until oil level stabilizes in sight glass.

4. ENVIRONMENTAL CONTROL SYSTEM Install seal environmental control system, if required, and drain piping.

5. PRESSURIZE FLUID LOOP Pressurize double seal buffer loop or external seal flush, if required, prior to admitting fluid into pump casing.

6. MOTOR ROTATION Rotation must be in same direction as arrow stamped on pump casing.

7. START PUMP Start pump with suction valve completely open while throttling discharge valve, to bring pump to design operating point.

8. HEAT EXCHANGER Adjust cooling flow to maintain gearbox sump temperature of 140° to 200°F (60° to 93°C).

9. 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.

10. DIFFUSER CAVITY VENT Ensure diffuser cavity vent is open. (Plug must be removed).

Note: Process fluid may accumulate causing

a potentially hazardous situation if diffuser cavity vent is not properly vented.

STEP 21

Visually inspect helical gear (122A), spur gear (122C) and pinion gears (132B and 132C) for pits, chips, gear tooth wear or excessive wear between gear and shaft. The thrust runner and gears are shrink fitted to the shaft. Use a 10 ton hydraulic press or equivalent for gear removal. A new gear can be installed on the low speed shaft by heating the part to 250°F (121°C) and pressing it into position on the shaft. Using a 10 ton press, the part should be pressed rapidly into place to avoid heating of the shaft. In 400 hp gearboxes heat the gear to 375° - 400°F (190° - 204°C) and cool the shaft to 0°F (-18°C). No more than 0.001 inch (0.03mm) gap should exist between the shaft shoulder, gears, spacers, and bearings. The high-speed shaft assembly is dynamically balanced; high-speed shaft gears cannot be replaced in the field.

NOTE

Remove lube jets and journal bearings. Clean all lube passages with solvent and blow dry with clean air. Clean all other parts thoroughly and lubricate with ATF or light turbine oil. Reinstall jets into housings immediately.

Page 44: Instruction and Operation Manual - Sundyne and Operation Manual ... Pump Mechanical Seal Troubleshooting ... of Sundyne manufacture (except mechanical seals)
Page 45: Instruction and Operation Manual - Sundyne and Operation Manual ... Pump Mechanical Seal Troubleshooting ... of Sundyne manufacture (except mechanical seals)

Step 29 Inspect anti-friction bearing (125C and 125D) for smooth rotation, worn outside diameter of outer races and snugness of the inner races on the shafts. Replace if bearings have been in operation for more than one year, if rotation is not smooth, or if outside or inside diameters are worn.

CAUTION It is essential to replace anti-friction bearings with the manufacturer’s approved replacement bearings. Non-approved replacement bearings may jeopardize mechanical integrity of the gearbox/pump. Anti-friction bearings should be pressed onto the shaft using a press which contacts only the inner race. Bearing damage will occur by pressing or pulling the outer race. No more than 0.001 inch (0.03 mm) gap should exist between bearings, spacers, gears and shaft shoulders. Do not use heat to assemble bearings to the shaft. Inspect the inside of the anti-friction bearing liners, see Figure 27. If a bearing liner inside diameter is more than referenced in Figure 27, replace the gearbox input housing (101B), gearbox output housing (101A), or bearing plate (102), whichever contains the worn liner. Bearing liners are not replaceable in the field.

Step 30

If the gearbox or lube system has been contaminated with particulate matter or process fluid, remove the pressure relief valve (175), lube jets (174 A, B, C, and D) and flush out the oil passages. The lube jets are drilled with a .032 inch (0.8128 mm) diameter hole. Take care not to use Teflon® tape downstream from the oil filter (i.e. oil pressure gauge fitting) because small pieces of the tape may block the lube jet.

Follow steps in reverse order for reassembly. Refer to pages 51 through 59 for clearance adjustments

Note: Before operating the pump, ensure that the diffuser cavity vent is open.
