SECTION I - PUMP DESCRIPTION

The Union Pump Company VLK is a Vertical In-Line Centrifugal pump designed to satisfy a wide range of refinery and petrochemical services. The VLK pump is manufactured in accordance with and meets or exceeds the requirements of API 610.

SECTION II - INSTALLATION & HANDLING

Inspection

Upon receipt, carefully inspect the pump for damage and check against the bill of lading. Report any damage or shortage to the carrier's local representative and send a copy to Union Pump Company. When uncrating, be careful not to discard any small accessories that may be attached to the crate.

Handling

Lift the pump assembly without motor using the lifting eyes. Follow any special handling instructions on the Outline Drawing included in the final data package.

Short-Term Storage (Less than 6 months)

When it is necessary to store the pump for a short time before it can be installed, place it on a skid in a dry location. Protect it thoroughly from moisture, sand, grit and other contaminants. Do not remove the protective covers on the suction and discharge flanges

Long-Term Storage (Greater than six months)

More thorough precautions are required if the pump is to be stored for an ex-tended period. Perform the following at six-month intervals:

1. Coat all unpainted exterior machined surfaces liberally with a light petroleum grease or equivalent rust preventative.

2. Rotate pump shaft 3 -1/2 turns (180° from original position).

CAUTION: Motor lifting lugs are for lifting the motor only. Never lift the pump assembly using the motor lifting lugs. Pump assembly may be top heavy. When lifting, provide proper support so that pump cannot tip sideways.

Installation, Operation, and Maintenance Manual

3. Remove the protective covers on the suction and discharge flanges. Remove any visible rust on internal surfaces and coat with rust preventative. Replace protective covers on the flanges.

NOTE: Accumulation of condensation in the pump must be avoided. Store the equipment away from climatic extremes. Do not store the pump in areas of high ambient variation, as damage to bearings may occur.

Auxiliary equipment such as drivers, mechanical seals, and instrumentation may require additional preparation for long-term storage. Refer to the manufacturer's literature for specific instructions.

Location

Install the pump as close to the suction source as practical. Ensure sufficient clearance around the pump to allow for cooling and maintenance accessibility.

SECTION III - PIPING

General

Support suction and discharge piping independently near the pump so that when flange bolts are tightened strain will not be transmitted to the pump casing. Piping must align with the pump flanges. Never force piping into place at suction or discharge flanges.

If an expansion joint or non-rigid pipe coupling is used, install a pipe anchor between the fitting and the pump. Proper installation of the pipe anchor will eliminate any objectionable forces on the pump.

It is good practice to increase the size of suction and discharge piping leading to the pump nozzles in order to decrease the head loss due to friction. Arrange piping with as few bends and fittings as possible. Use large radius elbows wherever possible (Figure 1).

Flush all piping thoroughly to remove any foreign matter before connecting to the pump.

Suction Piping

1. The nominal suction pipe diameter must be as large as or larger than the nominal suction size. Suction piping should be as short and direct as possible.

2. Ensure that suction lines are sealed to avoid leakage and air pockets.

Installation, Operation, and Maintenance Manual

7

3. Reducers, if used, must be eccentric and installed with the sloping side down.The reducer must be located at least five (5) pipe diameters from the pump suction flange.

4. Suction strainers, if used, must have a net free area of at least three times the suction pipe area.

5. When working under suction head or flooded suction, install a gate valve in the suction line to permit closing the line for pump inspection and maintenance.

NOTE: Never throttle the pump with the suction valve.

Discharge Piping

1. A check valve and gate valve should be installed in the discharge line. The check valve, placed between the pump and gate valve, protects the pump from excessive pressure and prevents pumpage from running back through the pump in the event of driver failure. The gate valve is used in priming, starting, and shutdown of the pump.

NOTE: Close the gate valve before stopping the pump. This is especially important when pump is operated against high static head.

2. If increasers are used on the discharge, they should be located between the check valve and the pump.

SECTION IV - PREPARING FOR OPERATION

Driver Lubrication

Motor bearings should be serviced and lubricated as outlined in the motor manufacturer's instructions provided in the final data package.

Mechanical Seals

The VLK pump is fitted with a mechanical seal which complies with the service requirements outlined on the pump data sheet. The seals are factory installed and no adjustment is required prior to pump operation. Seal installation details are provided in the final data package.

NOTE: If your pump has cartridge type seals, rotate the locking plates away fromthe seal sleeve and secure before operating the pump.

Installation, Operation, and Maintenance Manual

Seal Flush Piping

Seal flush piping has been installed in accordance with the service requirements outlined in the pump data sheet and the seal manufacturer's recommendations. Refer to the Outline Drawing provided in the final data package for specific seal flush piping details. If the pump is fitted with an auxiliary seal flush reservoir, do the following before operating the pump:

1. Connect a vent line to the flange or union at the top of the reservoir. 2. Fill the reservoir and piping through the filler hole. 3. Pipe the gauge connection to a gauge or pressure relay.

NOTE: Be sure that the liquid level in the reservoir is between the minimum and maximum markings. Never overfill or under fill.

Shaft Alignment

The motor and pump shafts have been aligned at the factory, however, it is recom-mended that alignment be rechecked before operating the pump.

Rotation

Correct rotation for all VLK pumps is counterclockwise (CCW) as viewed from the top of the motor. To check rotation, remove the coupling guard and coupling. Make momentary contact with the motor starter to verify correct rotation.

High Temperature Operation

Pumps handling liquids at temperatures above 300 °F (150 °C) should be brought up to operating temperature before start-up. This can be accomplished by circulating hot pumpage through the pump. Control the circulation so that the pump casing temperature rise does not exceed 150 °F (66 °C) per hour. The pump casing temperature must be within 75 °F (24 °C) of the pumpage before start-up and operation.

WARNING: Be sure that power to the motor is off and locked out before removing or installing the coupling or coupling guard.

WARNING: Keep clear of rotating components when checking motor rotation. Be sure that tools and loose hardware are clear before starting motor.

Installation, Operation, and Maintenance Manual

SECTION V - STARTING THE PUMP

Start-up Checklist

Before starting the pump, check the following:

1. Rotation CCW viewed from top of motor 2. Seal locking plates removed 3. Seal flush connected 4. Vent and drain lines installed 5. Motor bearings lubricated 6. Pipe connections and plugs tight 7. Coupling installed and torqued 8. Pump shaft rotates freely 9. Coupling guard installed

10. Suction valve open 11. Discharge side in start-up position 12. Instrumentation connections made 13. Everyone standing clear

Priming

NOTE: The pump casing, suction line, and seal flush must be filled with liquid BEFORE the pump is started.

When the pump is located above the pumpage source, it must be primed to evacuate all air from the pump case and the mechanical seal chamber must be vented.

When the pump is located below the pumpage source or when there is positive suction pressure, the mechanical seal chamber must be vented. A connection is provided in the seal flush piping for this purpose. Open this connection during priming until liquid begins to flow from the vent. Close the connection before starting the pump.

Starting

A centrifugal pump usually requires less power to operate with the discharge valve closed than with the discharge valve open. For this reason, it is often an advantage to have this valve closed when starting.

NOTE: Open the discharge valve immediately after pressure is indicated on the discharge pressure gauge.

CAUTION: Hazardous or toxic liquids must be piped away from the vent connection to a safe containment unit.

Installation, Operation, and Maintenance Manual

10

Start the pump and bring it immediately to operating speed. Open the discharge valve slowly as soon as there is a discharge pressure indication. Continue opening the discharge valve until rated capacity and discharge pressure are obtained. If the

rated conditions cannot be obtained, refer to the Trouble Checklist in Section VIII.

SECTION VI - OPERATION

Operating Capacity

Centrifugal pumps should not be operated at greatly reduced capacity or with a closed discharge valve because the energy required to drive the pump is converted to heat and the temperature of the liquid may reach its boiling point. If this occurs, the rotating parts are exposed to vapor with no lubrication and damage to internal parts will occur.

There are several means to protect the pump from such possible damage:

1. Liquid temperature sensor to shut the pump down if the pumpage temperature exceeds a predetermined level.

2. Constant open by-pass between the pump discharge and the first valve in the suction source.

3. Suction pressure sensor to shut the pump down if the suction pressure drops below a predetermined level.

4. Vibration sensor to shut the pump down if the vibration level exceeds a predetermined value.

NOTE: Never throttle pump on suction side.

Freezing

During cold weather when the pump is not in operation, the pump should be drained to prevent the liquid inside from freezing.

Pumps used for stand-by service must be kept ready for operation. Circulate pumpage through pump and keep bearings lubricated. Contact Union Pump Company for recommendations concerning pumps used in stand-by service.

WARNING: If the pumpage is toxic, flammable, or corrosive, take proper precautions for handling pumpage before draining the pump.

Installation, Operation, and Maintenance Manual

11

Changing Operating Conditions

Before making any changes in the operating conditions of the pump, contact Union Pump Company and provide complete data on the new operating conditions.

Shut-Down

To avoid water hammer, it is recommended that the discharge valve be closed just prior to shutdown of the pump.

SECTION VII - OPERATIONAL CHECKS

First 60 Minutes

It is recommended that the following parameters be recorded at 10-minute intervals during the first 60 minutes of operation and periodically thereafter:

1. Suction and discharge pressures 2. Pumpage temperature 3. Vibration levels 4. Leakage

Satisfactory operation is indicated by correct capacity and discharge pressure. Keep records for future troubleshooting reference and performance trend analysis.

Periodic check of the items listed below will ensure the pump is maintained in its best operating condition.

Mechanical Seal

Check mechanical seals for leakage during the first hours of operation. Minor leakage through the seal usually stops after a short run-in period but if it continues shut down the pump and investigate the cause.

Excessive leakage past the seal generally indicates worn or broken parts requiring replacement. A chronic leakage condition should be reported to Union Pump Company for further investigation.

Lubrication

Motor bearings should be serviced and lubricated according to the motor manufacturer's instructions. Consult lubrication directions on nameplate and literature provided in the final data package.
