Centrifugal mud pumps are rotodynamic pumps utilizing a rotating impeller that creates flow by energizing a fluid (mud). Centrifugal pumps are commonly used to agitate liquids allowing them to flow through pipes. The fluid (mud) enters the centrifugal pump impeller near the rotating axis and is then accelerated by the impeller. From there, the fluid (mud) flows radially outward into a diffuser or casing chamber and then exits into downstream piping.

When choosing a size and type of mud pump for your drilling project, there are several factors to consider. These would include not only cost and size of pump that best fits your drilling rig, but also the diameter, depth and hole conditions you are drilling through. I know that this sounds like a lot to consider, but if you are set up the right way before the job starts, you will thank me later.

Recommended practice is to maintain a minimum of 100 to 150 feet per minute of uphole velocity for drill cuttings. Larger diameter wells for irrigation, agriculture or municipalities may violate this rule, because it may not be economically feasible to pump this much mud for the job. Uphole velocity is determined by the flow rate of the mud system, diameter of the borehole and the diameter of the drill pipe. There are many tools, including handbooks, rule of thumb, slide rule calculators and now apps on your handheld device, to calculate velocity. It is always good to remember the time it takes to get the cuttings off the bottom of the well. If you are drilling at 200 feet, then a 100-foot-per-minute velocity means that it would take two minutes to get the cuttings out of the hole. This is always a good reminder of what you are drilling through and how long ago it was that you drilled it. Ground conditions and rock formations are ever changing as you go deeper. Wouldn’t it be nice if they all remained the same?

Centrifugal-style mud pumps are very popular in our industry due to their size and weight, as well as flow rate capacity for an affordable price. There are many models and brands out there, and most of them are very good value. How does a centrifugal mud pump work? The rotation of the impeller accelerates the fluid into the volute or diffuser chamber. The added energy from the acceleration increases the velocity and pressure of the fluid. These pumps are known to be very inefficient. This means that it takes more energy to increase the flow and pressure of the fluid when compared to a piston-style pump. However, you have a significant advantage in flow rates from a centrifugal pump versus a piston pump. If you are drilling deeper wells with heavier cuttings, you will be forced at some point to use a piston-style mud pump. They have much higher efficiencies in transferring the input energy into flow and pressure, therefore resulting in much higher pressure capabilities.

Piston-style mud pumps utilize a piston or plunger that travels back and forth in a chamber known as a cylinder. These pumps are also called “positive displacement” pumps because they literally push the fluid forward. This fluid builds up pressure and forces a spring-loaded valve to open and allow the fluid to escape into the discharge piping of the pump and then down the borehole. Since the expansion process is much smaller (almost insignificant) compared to a centrifugal pump, there is much lower energy loss. Plunger-style pumps can develop upwards of 15,000 psi for well treatments and hydraulic fracturing. Centrifugal pumps, in comparison, usually operate below 300 psi. If you are comparing most drilling pumps, centrifugal pumps operate from 60 to 125 psi and piston pumps operate around 150 to 300 psi. There are many exceptions and special applications for drilling, but these numbers should cover 80 percent of all equipment operating out there.

The restriction of putting a piston-style mud pump onto drilling rigs has always been the physical size and weight to provide adequate flow and pressure to your drilling fluid. Because of this, the industry needed a new solution to this age-old issue.

As the senior design engineer for Ingersoll-Rand’s Deephole Drilling Business Unit, I had the distinct pleasure of working with him and incorporating his Centerline Mud Pump into our drilling rig platforms.

In the late ’90s — and perhaps even earlier —  Ingersoll-Rand had tried several times to develop a hydraulic-driven mud pump that would last an acceptable life- and duty-cycle for a well drilling contractor. With all of our resources and design wisdom, we were unable to solve this problem. Not only did Miller provide a solution, thus saving the size and weight of a typical gear-driven mud pump, he also provided a new offering — a mono-cylinder mud pump. This double-acting piston pump provided as much mud flow and pressure as a standard 5 X 6 duplex pump with incredible size and weight savings.

The true innovation was providing the well driller a solution for their mud pump requirements that was the right size and weight to integrate into both existing and new drilling rigs. Regardless of drill rig manufacturer and hydraulic system design, Centerline has provided a mud pump integration on hundreds of customer’s drilling rigs. Both mono-cylinder and duplex-cylinder pumps can fit nicely on the deck, across the frame or even be configured for under-deck mounting. This would not be possible with conventional mud pump designs.

The second generation design for the Centerline Mud Pump is expected later this year, and I believe it will be a true game changer for this industry. It also will open up the application to many other industries that require a heavier-duty cycle for a piston pump application.

As an oilfield drilling fluid centrifugal pump, it is used to power the desander, desilter, and jet mixing device. It can also be used as a mud pump auxiliary grouting and wellhead replenishment pump.

According to the large solid particle characteristics of oilfield drilling fluids and the liquid characteristics of complex and diverse chemical agents, the design of drilling fluid sand pumps should pay attention to the impeller and pump casing of the sand pump to comply with the law of two-phase flow to reduce wear and corrosion. The flow rate of the designed centrifugal pump should be consistent with the head and the matching of the hydrocyclone. The design requirements of the shaft end of the centrifugal pump need to meet the tight sealing standard. Because the centrifugal pump transports a large amount of sand-containing materials, the sealing requirement of the shaft end is relatively high. The medium conveyed by the centrifugal pump is corrosive and abrasive, and the internal structure of the pump is easily damaged. The design should have an effective blocking structure to block particles from flowing between the front and rear guard plates of the impeller.

Oilfield drilling fluid centrifugal pump specifications include: 5.5KW 7.5KW 11KW 15KW 18KW 22KW 30KW 45KW 55KW and other power centrifugal pump, mud sand pump. Generally, drilling fluid sand pumps are divided into horizontal and vertical centrifugal pumps.

Gravel pump is also a kind of centrifugal pump. The centrifugal pump plays an important role in the mud solids control system of the drilling platform.

Tobee® Mission Magnum I Pumps are proven as reliable, heavy-duty, low-cost slurry pumps. The 3×2×13 through 8×6×14 pumps all feature the same power end, which ensures production and reduced spare-part inventory requirements. The Mission MAGNUM I has been engineered for the toughest jobs in drilling, production, well-servicing, and industrial applications. The MAGNUM I is more powerful, more durable, and easier to maintain than any conventional pump in use today.

The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum is available in Magnachrome™, hard iron, stainless steel, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration).

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.
