How many times are pump operators forced to modify fasteners that are used to secure motors and/or pumps to baseplates? A warehouse spare is ready to be installed and nothing fits, i.e alignment is not successful, major piping does not bolt up cleanly, and operations are anxiously awaiting their new equipment.

During shop maintenance performed—probably at a well qualified OEM or independent repair facility—the solution would be to enlarge the through holes for hold down bolts. While not a perfect solution to frustrating installation issues, my experience has been that this simple modification can often provide almost instant relief.

Selecting the right pump and motor for a specific job can be challenging, so let us help! PumpWorks is dedicated to finding pump solutions to meet your needs. Our expert technicians ensure that your pump services and repair work is done right 100% of the time!

During the 1950’s the Mission” 1780 type “W” pumps were introduced to replace duplex pumps while creating the first low pressure mud system. The use of a high quality concentric type centrifugal pump allowed abrasive fluids to be mixed and transferred while reducing initial and maintenance costs for the drilling industry. The low-pressure mud system with Mission 1 780 Type “W” centrifugal pumps became the industry standard.

As well depths increased so did the need for heavier mud weights. When the mud weight began exceeding 14 ppg the need for a pump that could withstand greater horsepower loads arose. During the 1970’s Mission organized a design team that engineered the Mission Magnum. The Magnum was designed to have the same footprint, flange locations, and drive shaft diameter as the 1780 “W”. This allowed a 1780 to be replaced by a Magnum without any skid modifications. The Magnums were originally engineered with a 2-1/2″ shaft (3″ between the bearings), double row bearings with an engineered life of over 2 years at 200 HP, larger impellers and heavier frames. The Magnum allowed drilling contractors to upgrade their centrifugal pumps and mix heavier fluids.

The National Oilwell Varco” Mission centrifugal pump line has proven to be the best centrifugal design for handling abrasive mud. This pump line offers a broad selection of innovative features for a variety of routine, demanding, abrasive and corrosive applications. These pumps are designed for a wide range of flow rates, from a few gallons per minute to thousands of gallons per minute.

Each pump contains the finest materials, engineering and craftsmanship available in the industry. Described are like features of these pump lines and unique features are described on the following pages.

National Oilwell Varco utilizes unique design features developed for slurries. Three major differences from most pump designs include the concentric casing, wider impellers and increased re-circulation areas. Each feature contributes to reducing wear when handling abrasive fluids.

All of the pumps feature a concentric casing. This casing averages 37% thicker than conventional pump casings, and up to 50% thicker for the larger, mud pumping models. They are pressure rated at 1 .5 times the flange rating and are designed with a 1 /8″ erosion allowance. The concentric style casing has proven to offer the greatest pump life and reduced downtime. The walls of a concentric style casing are an equal distance from the impeller throughout the impeller circumference, which results in a smooth flow pattern. A volute style casing has a cutwater point that disturbs the fluid flow pattern creating an eddy. The concentric casing eliminates vibration, turbulence and aeration that is caused by the cutwater point in conventional volute pumps. It also reduces the high bearing loads and shaft deflection even at near shutoff flows.

The shaft is much larger in diameter than conventional pump shafts for heavy-duty performance, minimum deflection and increased operating life of the seal or packing. With a 2-1/2″ diameter at the seal area and 3″ diameter between the bearings these pumps can be direct connected or belt driven.

A properly serviced pulsation dampener is critical for your mud pumps’ efficiency, safety, and performance. Unfortunately, there aren’t many resources available to educate personnel on executing safe and effective servicing procedures. Please review the following steps with your personnel for safe pulsation dampener maintenance.

Pump failure can arise from some of the least conspicuous or expensive parts of the pump—the bolts and washers. Pump manufacturers should consider the following six factors when choosing bolts for their rotating assemblies.

Different process applications require specific bolt design, class, strength and Maintenance of Certification. Process application conditions such as speed, pressure, pump driver and other factors have an impact on

Rotary lobe pumps often operate at slower speeds, under 1,000 rpm, and higher viscosities compared to other pump designs such as centrifugal pumps, which are regularly run at 3,600 rpm. They often pump water and other low viscosity materials.

A bolt design that works perfectly in one pump style may fail quickly in another. Pump speed has a drastic impact on the rotodynamic bolt in pumps. The pump’s typical speed range needs to be considered when designing the bolt assembly. Low speeds will place a large amount of torque on the rotating assembly, while high speeds can lead to greater vibration on the bolt. Excess vibration can lead to the failure of pump components, including the rotodynamic bolts. Vibration causes a radial force on the bolt head and shank that can cause the bolt to loosen and shear the bolt (see Image 1).

The process pressure range will also cause failure in a similar manner to speed. The value of the discharge and suction pressure on the pump can cause vibration and destroy a bolt if it is not taken into account. Suction lift can be harsh on rotodynamic bolts. In an application where a pump is expected to regularly see more than 20 feet of suction lift on water, the bolting assembly should be examined. Applications with high vacuum cause excess vibration and radial forces and have been shown to break bolts that succeed in other applications.

The pump driver can also cause this same damaging vibration. The pump driver that can produce the largest amount of vibration is the diesel engine. The diesel engine drive imparts a greater vibration on the pump skid and therefore on the pump and bolt compared to an electric or hydraulic motor drive. A diesel engine drive combined with high suction lift and speed can be akin to a perfect storm for vibration and bolt failure.

The chemicals and temperatures that a bolt encounters are some of the primary considerations when designing the bolting assembly. Many rotodynamic bolts are subject to the process fluid of their respective pump and are subject to the same or more degradation than rotors, housings and other pumping components.

These bolts can be the hottest element in the pump and must often be constructed of a more resilient material than other pump components. These bolts are subject to tensional, axial and radial force in a relatively small cross-sectional area compared to other pump elements. All other decisions in bolt design must follow the material selection since every material has different guidelines.

Different bolt designs and geometries have varying strengths and weaknesses and should be chosen depending on the pump application and service duty. Socket head cap screws (SHCS) are a common bolt design in pumping applications. The SHCS bolt heads have a smaller diameter compared to similar hex head bolts and are therefore easily incorporated into almost any assembly. Due to their widespread use, these bolts are available in a near infinite number of combinations of diameters, lengths, grades and materials.

Hex head screws and bolts, particularly flanged hex head screws (FHHS), can also be used with success in many pumping applications. The FHHS bolts incorporate a flange that distributes the pressure where the bolt head sits. The flange design can prevent loosening in cases where a SHCS bolt will back out of the threaded hole and potentially shear. FHHS bolts are less common and may not be suitable for a pumping application depending on the chemicals and other elements present in the process fluid. The service duty of the pump must also be kept in mind. Reversibility and run time per day impact the bolts needed for rotodynamic pumps.

The application of a threadlocking product to the rotodynamic bolt threads is often necessary to prevent the bolt from rotating separately from the pump components. The manufacturer’s instructions must be followed to fully generate the strength of the threadlocker. These products may require up to 72 hours to cure depending on substrate material, bond gap, temperature or other factors. Threadlockers have been shown to be one of the most effective methods of reducing overall bolt loosening or relaxation.

Most people assume that a stronger—therefore higher grade—rotodynamic bolt will always last longer. But the bolt’s lifespan is not only affected by the strength. Bolt manufacturers rated different grades of bolts at different torques for a reason. The bolt recommended torque value helps the bolt to hold tension properly and ensures that the bolt does not loosen after installation.

The necessary torque value can be very high for some higher grade bolts. The limitations of the pump must be considered when choosing these bolts. It is not beneficial to the overall pump assembly to use a bolt requiring a recommended bolt torque that could cause too much force on the pump assembly. The use of torque that is too high can cause failure in another part of the pump and torque that is too low may not properly maintain the pump assembly.

A typical centrifugal pumpis constructed of a rotary pump shaft with one or more impellers attached. As the impellers rotate in sync, the pump converts enough energy to move fluids in the desired direction.

Centrifugal pumpscan be radial or axial, with radial pumps pushing energy through downstream piping and axial pumps generating asuction liftingeffect with the impellers. Either are simple enough processes, but something could go wrong. When that does, you’ll need to troubleshoot and fix the problem.

If yourcentrifugal pumpstops working as it should, is it time to replace it or call in a professional? Neither may be necessary if you can figure out the problem and solve it independently. Here are some of the most commoncentrifugal pump problemsand solutions.

Impellers rotating in the wrong direction is a common problem withcentrifugal pumps. If the impellers turn the wrong way, they could cause severe damage to the pump. When wiring power to the pump’s motor, it’s critical to verify which way the motor turns. You can “bump start” the motor to do this.

Another common problem with these types ofcentrifugal pumpsis leakage. When materials escape the pump and create a mess, this is a serious issue. Excessive temperature, corrosion, or pressure can loosen the joints and seals, allowing fluid and debris to escape.

But there may be a simple fix. Stopping your leaky pump could be as easy as tightening the fasteners surrounding the joints. In other cases, however, you may need to replace a gasket or mechanical seal.

There is probably something wrong with your pump if it takes too long to re-prime. The most common cause of a slow re-priming pump is excessive clearance, leading to inefficiency and overheating. But other possible reasons exist as well, such as a leaking gasket, a clogged recirculation port, or a worn-out volute.

Pump seizure can happen for several reasons, including foreign objects entering the pump, low flow operation, and off-design conditions. Inspect the pump for foreign objects and debris first and then check the impellers and power source.

When you begin to see the pump vibrating too much or notice usual noises coming from the device, this could signify a serious issue. Often, vibrations and noises tell you that you have failed bearings or a foreign object stuck inside the pump.

Start with the most straightforward thing first and look for debris or foreign objects. When noises and vibrations occur together, the pump could be experiencing cavitation and may need to be examined by a professional.

Debris in your pump can create havoc with many of its parts and systems. If your pump isn’t pumping or is less efficient than you want, check for a cloggedsuction pipeor debris in the impeller.

Incentrifugal pumps, overloading occurs when the driving motor draws excess current, which results in greater than normal power consumption. Pumps should start with a minimum load with discharge valves open. If the power drawn by the pump increases too much, it may ultimately lead to tripping or overloading of the motor. Some of the most common causes of pump driver overload include:

If you notice that the pump isn’t operating efficiently anymore, meaning it’s taking too long for it to pump out fluid, some of the most common causes of this problem include the following.

If yourcentrifugal pumphas become corroded, it could be due to a chemical compatibility issue. The wetted parts of a pump can be made from a variety of materials — ceramics, metals, thermoplastics, and elastomers. The resistance of these parts to various liquids, chemicals, and temperatures will vary. So you must select a pump designed with your particular application in mind.

Centrifugal pumpsshould not feel hot to the touch. When they do, this is a sign of trouble and something you want to address immediately. There may be a blockage in the suction strainer, the recirculation port, the valve, or the open-ended discharge line. The pump will be less efficient if you ignore the issue and may eventually fail.

There is a wide range ofcentrifugal pumpsavailable that will give your operation the fluid-transfer services it needs over the long term. These are excellent, low-cost solutions for most high-capacity, low-pressure situations. But if yourcentrifugal pumpisn’t operating efficiently or at all, this list of common problems may help you troubleshoot the issue.

If you aren’t currently experiencing any problems with yourcentrifugal pump, then it is a great time to look intopreventative maintenance to ensure issues don’t arise in the future.

A 2011 model year car is "generally" too new to have a bolt so stuck that it is broken on removal. It is possible the mechanic encountered a stuck bolt but simply used the wrong technique to remove it (common mistake). It is possible, but less likely, that the bolt was defective. Either circumstance can be determined, in a forensic examination of sorts, by examining what remains of the bolt, the amount of corrosion, and other standard engineering factors. Again, though, simply due to the newness of the vehicle I would be very suspicious of any "reasons" (or excuses) given to you for a bolt breaking. Unless the car is more than 10 years old, the real "reason" is almost always improper disassembly. Furthermore, charging $1,100 to fix a broken bolt is unheard of, unless you are working on the Space Shuttle, and so obviously there is more to this story. YourMechanic can take over the job, if the car were towed to your residence but then, of course, you would have to disentangle yourself from the present shop. Keep the old broken segment of the bolt and take photographs of the stub that is stuck in the head or block and the area upon removal. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
