mud pump valve seat failure brands

The valve seat often cracks inside of the seat flange area. Once the seat cracks, a wash point occurs, washing out the fluid end. Also, changing valve seats are one of the biggest maintenance headaches.

As a result of our extensive research, we have transitioned to our new patent-pending Super Seat® design. The Super Seat® is in full compression AND has tungsten carbide only where it matters - in the strike face or metal to metal seal area.

The new Super Seat® design enables us to offer a 4 series valve seat for only $89 and a 5 series seat for just $98! And, since there’s no flange to break, wash points in the fluid end are a thing of the past. This new seat will reduce downtime and protect a failure that happens much more often than it should.

Customers said they wanted long-lasting, easy-to-use valves and seats, and we delivered. Made from domestically sourced steel, GD Energy Products valves feature a two-piece friction-welded design, proprietary bonded inserts, and innovative geometry to deliver significantly longer life. GD Energy Products’ field proven Valves & Seats meet API Standard, and come with our “Ready Inventory” promise that we’ll have it in stock, when you need it.

Our full-open valves and seats are designed for use in GD Energy Products PZ, F-Series, and National 12P lines of triplex drilling pumps. This gives you options to use these parts across your whole fleet of pumps.

The Caliber® 4-web valve and seat are designed for today’s high pressure drilling conditions. Each piece is forged from a single piece of proprietary, high-strength alloy steel and is case hardened to precisely controlled levels. We have molded our high temperature, high impact resistant urethane to the valve body in order to eliminate the existing gap you will find on replaceable insert type valves.

The 4-web design holds the valve weight to a minimum by increasing the load bearing area. In order to allow quick flushing of solid matter we use a steep angle that also increases the metal-to-metal sealing area. Each part is individually inspected to ensure performance and satisfaction.

The Patriot Harsh Duty Valve is a bonded urethane valve that will hold up in the most extreme drilling environment. The Patriot HD offers the strongest urethane bond of any valve for increased service life and a stronger seal.

Superior Performance, Long Run Life, Excellent Abrasion Resistance and Sealing Surface coupled with the highest rated chemically resistant urethane make the Patriot HD Valve an excellent choice for any drilling application.

Mud Pump Valve & Seat are made of premium alloy steel through one-piece forging and carburizing treatment processes, thereby ensuring high intensity. In addition, the precise calculation is performed and CNC machining is conducted for the dimensional matching of the valve seat and valve body working angles to enhance the service life of the valve body and valve seat. Our valve products are able to work smoothly in normal mining and digging conditions for over 400 hours.

Mud pump valve seats are used in on-shore and offshore oil and gas drilling operations and in pumps used in land-based fracking operations. Valves used in these types of pumping equipment operate at a very high frequency – up to one hertz (one cycle per second) – and are prone to high wear and degradation from hysteresis. Parker’s premium grade valve seats feature our Resilon® Polyurethane which has a high modulus of elasticity to successfully withstand high frequency operation and resist hysteresis.

Where typical urethane valves may last up to 400 hours, our proven valve seat designs with Resilon Polyurethane have lasted up to 800 hours (400 hours longer) – greatly improving drilling productivity through longer life. Longer valve seat life means maintenance intervals can be extended and production jobs can be completed before service is required.

MKP provides a full range of full open, 3 web, 4 web and plate type design valves and seats available in API 4 thru 8 sizes to fit all major mud pumps and accommodate for all types of drilling conditions, mud properties and temperatures reaching up to 350°F.

According to the use of mud pumps in the jurisdiction, valve box puncture, bearing burnout, and abnormal noise are all frequent failures that affect the normal use of mud pumps. Therefore, carefully studying the causes of the above problems plays a key role in prolonging the service life of the mud pump.

The drilling mud pump valve box is an important component of the hydraulic end of the mud pump, because the working conditions of the mud pump valve box are harsh working environments such as high pressure, high sprint, and high abrasiveness.

The main reasons for the leakage of the valve box of the mud pump are: long-term high-pressure use, the material of the valve box is fatigued, and when penetrating cracks occur, the current conditions cannot be repaired.

Because the working conditions of the drilling pump valve are very bad, the valve disc and valve seat of the discharge and suction valves have an impact in each flush. The higher the pump speed, the greater the impact and scour wear.

Because of this, the working frequency of the drilling pump is not very high. Even so, the working life of the mud pump valve is still very short, and it is one of the weakest links in the drilling pump. The valve disc and valve seat need to be replaced frequently during work.

According to the valve box used and maintained, most of the puncture leakage occurs at the joint surface of the valve seat and the valve box. Therefore, it is necessary to replace the valve seat regularly.

At the same time, check the inner and outer walls of the valve box. When installing and replacing the valve disc and valve seat, the valve seat must be cleaned to ensure that the fitting surface of the mud pump valve box and the valve seat is clean and free of contamination, and there can be no anti-rust oil on the valve seat, and do not apply any oil stains.

Through correct installation and replacement of valve disc, valve seat and careful inspection of valve box, the fatigue limit of valve box can be reduced, thereby prolonging the service life of mud pump valve box.

When there is a puncture in the valve box, our current repair method is welding repair, but the effect is average. Generally, if the surface is punctured, or there are obvious cracks, it can be used through the car and then welded to the original size.

However, penetrating cracks cannot be seen with the naked eye. Now we basically rely on experience in repairs, and it is difficult to fundamentally solve the problem. Many valve boxes are dark wounds that cannot be determined penetrating during maintenance. Its use can be determined from the integrity of the surface of the valve box of the mud pump.

Some valve boxes with good appearance will be completely punctured as long as they are exposed to high pressure during the specific use process. Therefore, many repaired valve boxes will be seriously punctured within a few days after being put into the well, causing rework and making us overhaul. The service life of the latter pump head is significantly shortened.

Full open – Not only is the full open seat more evenly loaded but the full open design results in less stress transferred to the module overall. Notice even the highest stress areas are much lower (11,000psi) than the web seat.
