This specification covers the preservation and storage procedure for shipment of new-build NOV Triplex Mud Pumps shipped from the manufacturing plant.

This specification is intended to provide preservation of new-build NOV Triplex Mud Pumps for six (6) months from the shipment of the mud pump from the manufacturing facility. If a pump is to be stored for a period of time exceeding six (6) months, additional precautions should be taken as outlined in this specification.

National Oilwell Varco recommends that all pumps are inspected for any signs of corrosion and for proper preservation at a minimum every three (3) months for pumps stored outside and every six (6) months for pumps stored indoors.

Drain all water and clean out liner wash tank. Remove drain plug in bottom of liner wash pump and drain water then reinstall plug. Remove discharge flange from liner wash pump and pour one (1) pint of inhibiting oil-based concentrate (Cortec VpCI 329 Vapor Corrosion Inhibiting oil-based concentrate or equivalent) into liner wash pump. Rotate two (2) revolutions by hand to distribute the product. Re-install discharge flange.

Drain all oil from pump power end sump and remove crosshead covers and inspection covers. Clean out oil sump as per National Oilwell PS-3081 (Mud Pump Cleanliness). Spray all internal machined parts of power end and crosshead area with inhibiting oil-based concentrate (Cortec VpCI 329 Vapor Corrosion Inhibiting oil-based concentrate or equivalent). Rotate pump turn and re-spray. Pour quantity of inhibiting oil-based concentrate specified in the table below into power end sump.

Mud Pump Models Quantity of Inhibitor 14P, FC 2200 5 Gallons 12P, 10P, HD or A1700/1400PT, FB/FC/FD 1600, FB 1300 3 Gallons 9P, 8P, B or A850-1100PT, F/FD 1000, F 800 2 Gallons 7P, A600PT, FD 500 1 Gallon

For pumps equipped with chain drives, spray internal machined parts inside chain cases with inhibiting oil-based concentrate (Cortec VpCI 329 Vapor Corrosion Inhibiting oil based concentrate or equivalent).

Remove fluid end valve covers, seals, valves springs and seats and treat internal cavities of fluid ends, discharge manifold, discharge strainer block and suction manifold with rust preventative (CRC SP400 or equivalent). Coat threads with anti-seize (KOPR KOTE 10002 or equivalent) and coat bottom side of valve cover with rust preventative. Reinstall seals and fluid end valves covers hand tight. Customer liners, pistons, piston rods, valves, seats, springs and liner retention parts are not used for plant testing. These expendables are checked for preservation when packed and then shipped with the loose parts.

Remove breather and pack with loose parts for later shipment with pump. Seal breather hole with a greased solid plug. Affix a warning label near the breather opening (see Exhibit 1).

Spray all machined unpainted loose parts and expendables to be shipped with pump with rust preventative (CRC SP400 or equivalent). All parts will be wrapped or boxed to prevent damage.

Affix one (1) warning label (see Exhibit 2) to the power end pump cover and one (1) warning label on the fluid end assembly of the pump. Affix warning labels on each loose part container. In cases where the equipment will be boxed at an offsite export packer, a sufficient number of warning labels will be supplied with the shipment.

Indoor storage is preferred whenever possible; but if outside storage is required, ensure pump is stored away from salt water spray, sand blast or other adverse conditions. It is highly recommended that ship loose parts be stored indoors to eliminate conditions that promote condensation and direct sources of moisture.

Note: It is recommended that inspections be carried out on six (6) month cycles when pumps are in indoors and three (3) month cycles when stored outside.

Any pump that has been in storage will need a thorough inspection prior to start-up to insure it has not been damaged in any way and that all parts are properly in place. Failure to observe the following points can result in serious damage. Before servicing the pump, the power end sump and chain drives housings will need to be drained of any inhibiting additive. The Cortec brand products used for preservation are compatible with all lubricating oils and need not be totally removed when putting equipment into service.

To service the Fluid End after storage and prior to start-up, remove covers and thoroughly clean and inspect inside of the fluid end cylinders. Properly install valves, pistons, liners and all other fluid end parts. Carefully tighten all bolts, nuts, studs and working connections to specified torque requirements.

The initial startup procedures are written to assist the operator in preparing the pump packages for normaloperation. The startup procedures are separated into two categories: Part I: Pre-Commissioning, and PartII: Commissioning Procedures. It is suggested that a copy of these pages be made for each pump to beused as a check-off sheet.

Note: The rust preventative on the internal surfaces of the pump is oil-soluble and is compatible with the lubricants recommended above. It is not necessary to flush and drain unless the preservative has become contaminated (water, sand etc.).

Megger test the motors. Check each motor separately for the correct rotation. Reconnect if necessary. Megger test the blower motors. Check blower motors for correct rotation and quantity of air flow.

Clean liner wash tank, if needed, and fill with fresh clean water. Ensure that supply hoses and spray nipples are installed correctly. Start pump and adjust regulating valve to maximum flow without splash onto the extension rods.

Check to assure that all liners, valves, and pistons are installed properly in accordance with the installation instructions. Ensure that the liner end covers are installed on the rear end of the liners. Ensure that the baffle discs are installed on the end of the crosshead extension rods. Clean grease and paint from the exposed parts of the extension rods, checking for burrs. Coat rods with a light oil.

NOTE: When charging the bladder, make sure that the mud pump suction line valve has been closed and that all pressure has been bled off of the suction manifold surrounding the suction desurger

If a dampener is used, charge dampener with a hand-operated air pump to 10 PSI (0.7 bar). Once pump operations have been started, check the operation of the suction dampener by inspecting the sight glass. Add or release air pressure through the Shraeder valve to keep the diaphragm between the midpoint and the bottom of the sight glass.

Check the installation and the setting. NO SHUT-OFF VALVE is to be between the pump discharge and the relief valve. Ensure that piping from the discharge port goes directly to the mud tank/pit and is securely tied down, with a minimum downward slope of 1/4 per foot. Ensure that piping has pressure rating equal to the relief valve highest setting.

Remove the strainer screen from the housing and assure that it is clean and free from obstructions. Check the stud nuts for proper make-up torque.

Check the chain guards to ensure that the chains will not drag on the guard. Check the oil pump to ensure that the relief valve is installed on the suction side. Start the pump and ensure that the spray nozzles are spraying oil over the full width of the chain. Adjust the relief valve to 15-25 PSI output with the warm oil. DOCUMENT OR DRAWING NO.

Your National Oilwell Varco pump has been completely assembled and test operated under pressure before being shipped to the field. Unless otherwise instructed, the lubrication is drained from the power end and the expendable parts are removed from the fluid end. Before putting the pump into service, the following precautions and operations must be performed or checked.

2 SETTING THE PUMP The skids under the National Oilwell Varco pumps are suitable for most any type of installation. It should be noted, however, that the box type construction of the power frame has high resistance to bending but relatively less resistance against twist. Therefore, the support under the pump must be level and adequate to support the weight and operating forces exerted by the pump.

2.1 Land Installations In land installations, a mat of 3 X 12 (76.20 mm x 304.8 mm) boards laid side crosswise to the pump skids for the entire length, or at a minimum, at the points indicated in Fig. 2, is usually sufficient. The boards should be a few feet wider than the width of the pump skid runners. Wet or marshy locations may require a more stable foundation.

Suitable means, such as National Oilwell Varco pump spacers as shown in Fig. 3, should be used to keep the pump anchored and the drive in alignment. National Oilwell Varco mud pump spacers provide 8-1/2 (215.9mm) adjustment. Any desired length may be obtained by lengthening the standard pipe spacer, which is made of 3 (76.20mm) extra strong pipe.

2.1.1 Permanent Installations On permanent installations such as barge, platform, structural base, or concrete slab, where pump skids are bolted down, it is essential that the skids be properly shimmed to prevent possibility of twisting or distorting the power frame. The pump skids must sit solid on all shim points with bolts loose.

On barge installations, the pump skids are generally bolted down to T-beams running parallel and in line with the pump skids. Install shims at points shown in Figs. 2 and 4 and observe caution of proper shimming to prevent twist or distortion.

On installations where the power unit or electric motor is mounted integrally with the pump skids, the preferred installation would be to set the pump package on the T-beam skids and provide retention blocks rather than bolts to hold it in place. This will allow the pump to float and minimize the transfer of barge deck or platform distortion into the frame.

2.1.2 Installation of the Drive The drive between the mud pumps and the power source, whether V-belts or multi-width chains, should be installed with the greatest care to assure maximum operating life with minimum of unexpected or undesirable shutdowns due to drive failures.

When installing the drive sheave or sprocket, make sure all grease or rust preventative is removed from the shaft and the bore of the drive. Remove all burrs or rough spots from the shaft, key, and keyway. Fit key to the keyways in both the shaft and drive and install key into shaft keyway.

The final alignment of the V-belt sheaves should be checked after the V-belts have been installed and adjusted to their operating tension. If the sides of the sheaves are of equal distance from the centerline of the groove, check alignment by stretching TWO strings (fish line or piano wire preferred) along one side of the two sheaves, one above and one below the centerline, and moving one of the sheaves until the strings touch four points on the side of the sheave rims. This will determine that the centerline of the drives are parallel and the faces of the sheaves are square.

Adjust the belt tension by moving the sheaves apart until all of the sag has just been eliminated from the tight side of the belt and some of the belts on the slack side. Then increase the centers approximately (13mm) for each 100 (2540 mm) center distance. Example: On 150 (3810 mm) center, move pump an additional (19.5 mm).

DO NOT OBTAIN BELT TENSION BY PICKING UP END OF PUMP AND ALLOWING BELTS TO TIGHTEN UNDER WEIGHT OF PUMP AS END IS BEING LOWERED TO THE GROUND.

Proper installation and maintenance of the sprocket and chain drives are essential if good service life is to be obtained. Since many factors, such as chain width, center distances, speeds, and loads must be considered when determining the allowable tolerance for sprocket alignment, no good rule of thumb can be applied. The chain alignment must simply be held as nearly perfect as possible. A more precise alignment can be made by stretching two steel wires (piano wire) along one face of the two sprockets, one above and one below the centerline, and moving one of the sprockets until the wires touch at four points. This will determine that the centerlines of the drives are parallel and the faces of the sprockets are square.

The pump drive chain lubrication system on the majority of National Oilwell Varco pumps is an independent system having its own oil pump, reservoir, and drive. Fill chain case to the indicated level with a non-detergent oil as follows:

- Daily check of oil level. - Daily check on condition of oil. - Frequent check on oil pressure. (5-15 psi) (.352 - 1.06 kg/cm) - Volume of oil being applied to chain. - Condition of nozzles in spray tube. - Condition of oil pump drive (V-belts or chain)

NOTE: Oil pressure may be adjusted with the pressure relief adjusting screw on the rear of the pump housing. Pressure drops may also indicate suction and discharge filter screens need cleaning.

3 SUCTION SYSTEM REQUIREMENTS Individual installation conditions will dictate the design of the suction system. The suction of the FD-series pumps must have a positive head (pressure) for satisfactory performance. The optimum suction manifold pressure is 20-30 psi (1.75-2 kg/cm) for maximum volumetric efficiency and expendable parts life. This head pressure is best supplied by a 5 x 6 centrifugal pump with 40 h.p. 1150 rpm electric motor. This type of drive requires a device to automatically start and stop the centrifugal pump motor simultaneously with the triplex pump. On DC electric powered rigs a signal can usually be supplied from the DC control panel to energize a magnetic starter when the mud pump clutch air line will provide a set of contacts for energizing the magnetic starter when clutch is engaged.

The charging pump can also be belt driven from the triplex pinion shaft charging type of drive is not as efficient at slow speeds with viscous fluids.

Under some conditions the FD-Series pumps may be operated without a charging pump, provided the fluid level in mud pits is higher than the top of the liners, fluid being pumped is low viscosity and suction line must be short, straight and of at least the same diameter as suction manifold inlet.

The suction lines should be piped with valve arrangements so the charging pump can be by-passed so operation can be continued in event of charging pump failure or for maintenance. Operation without a charging pump can be improved by replacing the suction valve springs with a weaker spring.

Suction desurgers are a very effective aid for complete filling of the liners and dampening pulsations in the suction line which results in a smoother flow in the discharge line. If your pump is equipped with a suction desurger it must be pre-charged with compressed air before operations are begun. See suction desurger manual for charging instructions.

3.1 Caution Do not pipe the return line from the shear relief valve back into the suction system as a relief valve operation will cause a sudden pressure rise in the system vastly greater than the system pressure ratings, resulting in damage to manifold, suction desurger and centrifugal pump.

4 PREPARATION OF POWER END Your National Oilwell Varco pump has been completely assembled and test operated before being shipped to the field. Unless otherwise instructed, the lubrication is drained from the power end, and the expendables are removed from the fluid end for storage protection. Before operating the pump, the following must be performed or checked:

Before installing lubricant, open inspection door in cover and check oil reservoir for possible accumulation of condensation, etc., and drain and flush by removing the pipe plugs on each side of the pump.

Add the proper type and quantity of lubrication in the power end. Refer to the Lubrication Section of this manual, or lubrication plate on pump frame for type and quantity required.

Recheck oil level after pump has operated for a period of 15 minutes. Shut pump down and allow approximately five minutes for the oil level to equalize. Check at oil level gauge, Item 1, Fig. 1. It is usually necessary for a few more gallons of oil to be added due to a certain amount being retained in the crosshead area and frame cavities.

With reference to Figure 5, remove the diaphragm stuffing box and plate (1) and rotate pump so that crosshead is at the front of the stroke. Thoroughly clean the front of the crosshead and the face of the crosshead extension rod. Insert alignment boss on crosshead extension rod into the crosshead bore and tighten the retainer bolts (2) to the following torque. Safety wire bolt heads.
