Cavitation is an undesirable condition that reduces pump efficiency and leads to excessive wear and damage to pump components. Factors that can contribute to cavitation, such as fluid velocity and pressure, can sometimes be attributed to an inadequate mud system design and/or the diminishing performance of the mud pump’s feed system.

When a mud pump has entered full cavitation, rig crews and field service technicians will see the equipment shaking and hear the pump “knocking,” which typically sounds like marbles and stones being thrown around inside the equipment. However, the process of cavitation starts long before audible signs reveal themselves – hence the name “the silent killer.”

Mild cavitation begins to occur when the mud pump is starved for fluid. While the pump itself may not be making noise, damage is still being done to the internal components of the fluid end. In the early stages, cavitation can damage a pump’s module, piston and valve assembly.

The imperceptible but intense shock waves generated by cavitation travel directly from the fluid end to the pump’s power end, causing premature vibrational damage to the crosshead slides. The vibrations are then passed onto the shaft, bull gear and into the main bearings.

If not corrected, the vibrations caused by cavitation will work their way directly to critical power end components, which will result in the premature failure of the mud pump. A busted mud pump means expensive downtime and repair costs.

To stop cavitation before it starts, install and tune high-speed pressure sensors on the mud suction line set to sound an alarm if the pressure falls below 30 psi.

Although the pump may not be knocking loudly when cavitation first presents, regular inspections by a properly trained field technician may be able to detect moderate vibrations and slight knocking sounds.

Gardner Denver offers Pump University, a mobile classroom that travels to facilities and/or drilling rigs and trains rig crews on best practices for pumping equipment maintenance.

Program participants have found that, by improving their maintenance skills, they have extended the life of fluid end expendables on their sites. They have also reported decreases in both production and repair costs, as well as reductions in workplace hazards.

Severe cavitation will drastically decrease module life and will eventually lead to catastrophic pump failure. Along with downtime and repair costs, the failure of the drilling pump can also cause damage to the suction and discharge piping.

When a mud pump has entered full cavitation, rig crews and field service technicians will see the equipment shaking and hear the pump ‘knocking’… However, the process of cavitation starts long before audible signs reveal themselves – hence the name ‘the silent killer.’In 2017, a leading North American drilling contractor was encountering chronic mud system issues on multiple rigs. The contractor engaged in more than 25 premature module washes in one year and suffered a major power-end failure.

Gardner Denver’s engineering team spent time on the contractor’s rigs, observing the pumps during operation and surveying the mud system’s design and configuration.

The engineering team discovered that the suction systems were undersized, feed lines were too small and there was no dampening on the suction side of the pump.

Following the implementation of these recommendations, the contractor saw significant performance improvements from the drilling pumps. Consumables life was extended significantly, and module washes were reduced by nearly 85%.

Although pump age does not affect its susceptibility to cavitation, the age of the rig can. An older rig’s mud systems may not be equipped for the way pumps are run today – at maximum horsepower.

This handy derrick and substructure safety inspection app replaces paper forms for drilling rig components. Instead of tracking everything by hand when you"re in the field, this form app handles everything electronically from your smartphone or tablet. From the drill pipe, drive shaft and pick-up lines, to the drill stem, crown block and centrifugal pumps, it"s important to make sure that all drill handling equipment is in proper working order before being used in the field. Regular use of this easy-to-use inspection app with all drilling equipment helps ensure that all areas of the handling equipment, mud pump and drill floor are ready to go.

This example models a triplex pump with a predictive maintenance algorithm that can detect which parts of the pump are failing simply by monitoring the pump output pressure.

The Simscape model of the pump can be configured to model degraded behavior due to seal leakage, blocked inlets, bearing wear, and broken motor windings. MATLAB code shows how to accelerate testing by reusing results from previous simulations. The model can be used to generate training data for the machine learning algorithm and can be used to test the deployed algorithm. MATLAB Live Scripts show you how to develop the algorithm.

Mechanical, hydraulic, and electrical parameters are all defined in MATLAB which lets you easily resize the pump. The pump housing is imported from CAD.

What"s equally as important as your automatic taping and finishing tools? You need a reliable mud pump. The drywall compound pump, or mud pump, is necessary to quickly fill your automatic tools such as a flat box or automatic taping tool, and keep the job moving with minimal delay. Without a reliable pump, you’ll be spending more time fiddling with a pump that is difficult to clean, or worse, resorting to hand-filling your tools, which is time consuming, and counter productive.

No pump = no tools, so you need a workhorse that will withstand a lot, and get through your workday, every time. TheLevel5 Drywall Compound Pumpis constructed of billet aluminum, making it much stronger, and more durable than your typical cast aluminum construction.

Another important quality is resistance to corrosion. Tools built of poor quality and materials are prone to rust and corrosion. The anodization on the Level5 Drywall compound pump makes it highly resistant to corrosion, as well as wear and tear!

A good seal is important too! Typically for compound pumps, a rubber seal is used, but the problem with rubber is that it will slowly deteriorate, and before you know it, you’re leaking all over the place. The Level5 Drywall Compound Pump uses a composite urethane cup seal, which provides much longer wear life vs. the traditional rubber seals.

Working with mud can be messy, and when you’re on the job, it"s important to be able to easily clean and maintain your compound pump. You should not be spending any extra time fiddling with small screws or components to clean your pump, or to switch valves.

That’s why the Level5 Compound pump has easy clean features, like grenade pins and easy-release latches on its tube and handle. It also comes with a wrench, and a built-in wrench mount so that you are always prepared to switch from gooseneck to box-filler valve, or make a quick adjustment with ease.

Theoretically, yes you can, but it"s a slow process, and at which point you may be better off hand finishing, as you will impede the speed of the work. The combination of your automatic tools and your mud pump will pay for itself fairly quickly by the speed and quality job that you can achieve.

We think the Level5 Drywall Compound Pump is the best drywall mud pump on the market, and truly the underestimated workhorse in the arsenal of any professional drywall finisher. LEVEL5’s drywall compound pump has been made to meet finisher’s demand for reliability, affordability and workability. This beast of a taping tool is built to withstand years of heavy use. In fact, the Level5 compound pump has been tested for over 250,000 cycles without the need or repair, or replacement parts.
