The NOV triplex pumps have three cylinders with single acting. The pistons are moved back and pull in drilling mud through open intake valves. When the pistons are moved forward and the drilling fluid is pushed out through open discharge valves.

NOV Emsco FB-1600 Triplex Mud Pumps have many advantages they weight 30% less than a duplex of equal horsepower or kilowatts. The lighter weight parts are easier to handle and therefore easier to maintain. The other advantages include;

One of the more important advantages of triplex over duplex pumps, is that they can move large volumes of mud at the higher pressure is required for modern deep hole drilling.

NOV Emsco FB-1600 Triplex Mud Pump are gradually phasing out duplex units. In a triplex pump, the pistons discharge mud only when they move forward in the liner. Then, when they moved back they draw in mud on the same side of the piston. Because of this, they are also called “single acting.” Single acting triplex pumps, pump mud at a relatively high speeds. NOV Emsco FB-1600 Triplex Mud Pump has three pistons each moving in its own liner. It also has three intake valves and three discharge valves. It also has a pulsation dampener in the discharge line.

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).

Seal all other pipe work (air, water, and electrical) with plastic caps of the correct size and style. Electrical J-boxes are to be encased in protective plastic wrap. Place two (2) one- pound bags of desiccant inside each J-box before sealing with tape. Wrap pressure gauges with bubble paper and plastic.

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.

For storage preparations for main drive motors, National Oilwell Varco recommends that the original manufacturers instructions be followed. If space heaters are supplied, the J- box plastic wrap must be removed and the heaters should be connected throughout the complete storage period.

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 Power End after storage and prior to start-up, remove all covers and thoroughly clean and inspect all of the parts and finished surfaces. Check all of the bearings to make certain they are clean and in good condition. Fill the power end with clean EP oil of the proper viscosity to the proper level. Make sure oil is poured into the oil distribution trough and is worked into all of the bearings. Replace all covers and install breather.

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.

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.

The shims on all installations should extend the full width of the skid beam flanges and have a minimum length of 12 (305mm).

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.

Coat pinion shaft with a light coating of anti-seize compound or light oil and install the drive sheave or sprocket hub. Tighten hub bolts as indicated below:

When a wrench or length of pipe is used to increase leverage in tightening draw-up bolts, it is imperative to adhere to the wrench torque values given in the chart below. This adherence is important, because in mounting the hub, the tightening force on the bolts is multiplied many times by the wedging action of the tapered surface. This action compresses the hub for a snug fit on the shaft. If the bolt tightening forces are extreme, bursting pressure is created in the hub of the mounted pulley; this pressure may cause the pulley to crack. The hub bolts should always be tightened alternately and progressively.

Before installing the V-belts, check sheave grooves for wear. Worn or rounded grooves will destroy V-belts rapidly. The side walls must be straight. Sheave grooves must be free of dirt, rust or other extrusions which could damage the V- belts.

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:

REFER TO GENERAL LUBRICATION BULLETIN for approved lubricants and additional specifications. If any discrepancy exists between the recommendations in this manual and the General Lubrication Bullletin, those in the Lubrication Bulletin will take precedence.

Since this is an independent system, it will require the same maintenance or service attention employed on any other piece of machinery, including:

- 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 p
