novatech mud pump parts factory

Nova-Tech offers a wide variety of parts to keep your chemical metering pumps in operation. Some of these parts include gaskets, washers, valves, tubing and much more.

The frac pump valves and seats are also called valve and seat assembly. There are valve body, valve insert, valve seat, and O-ring, these four parts consist of the frac pump valves and seats, which are very critical vulnerable parts in fracturing pumps. In higher pressure frac pumps, the mating surface of the valve body and valve seat is generally a conical surface. Frac valves and seats are the no. 1 expendables cost. 8620H or 20CrMo can be used for forged frac valves and seats. Both the valve body and valve seat would be carburized or nitrided to enhance their impact resistance and wear resistance. Polyurethane is often used as the raw material for the valve insert. Compared with rubber, polyurethane has better strength and elasticity.

This FAQ lists some questions about frac pump valves and seats for you. These FAQs shall be able to answer some queries related to the well-service pump valves and seats.

Novatech is a valves and seats manufacturer in the US. Its first welding valves were supplied nationally in 1982. As one of the oldest and strongest frac valves and seat manufacturers, a wide variety of valves & seats manufactured by Novatech are used throughout the world.

Novatech’s four streamlined guide legs full open seat valve have greatly increased the reliability and performance. The web-type valve seat was achieved to maximize the metal-to-metal bearing area. However, the loads applied to the seat webs are not uniform, the flow is not limited because of the Novatech four streamlined guide legs and the metal-to-metal bearing area is regained, the Novatech full open valve seat assembly can keep the impact loads uniformly transmitted to the frac pump fluid end. One-piece valve bodies, the insert retention groove acts as a circular channel beam to add superior rigidity to the valve body.

The plungers size defines the frac pump fluid end size. The frac pump valves and seats change with the plunger size but not all the same, some fluid ends of different plunger specs also share the valves and seats of the same size. You can find the following charts which list the general sizes of frac pump valves and seats:

The frac pump valve section is divided into the suction valve and discharge valve on the drawings. However, in order to make the disassemble and maintenance of the frac pump valve convenient, the suction and the discharge valve body adopt the exactly same design. The suction valve body is located at the lower part of the frac pump fluid end, and the discharge valve is located at the upper part of the frac pump fluid end.

By the reciprocating movement of the plunger, the suction valve and the discharge valve continuously open and close. When the suction valve keeps opening and the discharge valve closing, the liquid pours into the frac pump fluid end cylinder cavity through the suction manifold and the suction valve to complete the liquid suction. When the discharge valve keeps opening and the suction valve closing, the liquid discharge from the frac pump fluid end cylinder cavity through the discharge valve land the discharge pipe to complete the liquid discharge.

In the operation of the frac pump, the frac pump valves and seats are constantly opening and closing. Therefore, the closing speed of the frac pump valves and seats require special attention. There is a certain impact that emerges due to kinetic energy changing at the closing moment of the frac pump valves. The impact strength is related to the mass and closing speed of the frac pump valves and seats. The greater the mass and speed are, the greater the impact strength will be. The shock is the main factor that triggers the frac pump valves and seats to be damaged. It makes the allowable closing speed is a key parameter of the frac pump valves and seats design.

You need to prepare sufficient spare frac pump valves and seats parts. The quality of frac pump valves and seats directly affect the performance of the frac pump fluid end. Tianyu Mfg. serves low cost and superior performance frac pump valves and seats. As the valve body is manufactured as a one-piece, which increased resistance to abrasion and extrusion, also minimizes insert movement, leakage, and separation from the valve.

When the insert is almost damaged across the surface and caused the valve to leak, replace the insert. After replacing, no leakage keeps them working. Leakage till happened, replace the frac pump valve body. The leakage caused by the insert failure would arise the valve washout and fail easily tend to rapid erosion.

Increasing the metal-to-metal bearing area between the valve and seat is the only method to lengthen the life span of the frac pump valves and seats. The bigger this area, the bigger the area to absorb the high-impact energy from valve closing. We recommend the following tips for you as a reference.

Manufacturer of valves and valve seats. The company offers well service valves, pistons, mud pump valves and seats and drilling products. It offers its services to military/defense and commercial industries.

Novatech"s machining cells consist of two turning centers equipped with automated gantry loaders. This view shows the original cell that was installed in 2001.

Oil wells use lots of pumps. At almost every step in drilling or operating an oil well, pumps are needed to get various materials in and out of the ground. All of these pumps require numerous valves to control the flow of these materials, many of which are highly abrasive or corrosive. As a result, these valves and the seats they mate with wear out and need to be replaced. Novatech Corporation is in the business of manufacturing these replacement components.

This 19-person shop in Dallas, Texas, was making many of these parts before it became a pump valve company with its own product line. Novatech started out as a job shop, with precision turning as one of its specialties.

Because pumps come in many sizes and types requiring many different sizes of valves and seats to match each pumps capacity, pump manufacturers have to supply a wide variety of replacement parts. These companies were looking for job shops that could produce the pump valve components that need to be replaced frequently. These parts consist largely of axisymmetric shapes, so lathe work is a main part of their production. Because Novatech was experienced at turning, the shop was a good choice for machining these valves.

The company eventually expanded to become a job shop supplier for several pump manufacturers. It began making components for both "mud" pumps used in oil well drilling along with components for well service pumps used to keep an oil well operating. In the meantime, the company continued to do other job shop work, such as defense-related contracts.

The 1990s saw many changes in the oilfield industry. There was widespread consolidation among the oilfield equipment dealers and distributors, leaving many of the independent equipment sellers with gaps in their valve product lines. A number of these sellers turned to Novatech to fill the gap.

Mr. Pitzer realized that his shop could manufacture the most popular valve types very efficiently and be highly responsive to the independent sellers serving oil wells in the field. Novatech was in the right position to make and market its own line of pump valves. Yet Mr. Pitzer didn"t want the shop to lose its heart and soul of a job shop. The shop would need all of its job shop flexibility, creativity and constant focus on efficiency to succeed in its valve business.

Two, he needed to preserve as much flexibility as possible. Given the wide variety of valves and seats that would comprise Novatech"s emerging product line, producing small batches (200 to 300 pieces) would best meet customer orders without creating excess inventory. More important, batches in this range matched the number of pieces that the heat treater could carburize at one time. At this batch size, the heat treater could provide the best turnaround time and lowest cost per piece.

At the time, the valves and seats were being machined on the shop"s CNC lathes, which were manually loaded and unloaded. It was clear that this approach was inadequate to handle the optimal batch sizes that were a key part of the production strategy. Several factors were holding back the productivity of these machines. One was operator fatigue. The valve parts are heavy, ranging from 7 to 17 pounds each. Cycle times were around 2 to 3 minutes per part. That meant a lot of lifting and stretching for the operator during an entire shift. "At most, we could expect an operator to do 100 to 150 parts per shift, depending on the weight of the part," says Mr. Pitzer. "We needed to double that output per operator and make better use of their abilities."

The automatic gantry systems consist of a chain-driven carrousel with 25 stations, a vertical arm that raises and lowers the gripper, and a crossbeam that carries the arm back and forth between the machine and the carrousel. The double-sided gripper is designed to grasp and manipulate the workpiece. The construction of these systems is modular, allowing the loaders at Novatech to be configured for the specific machine tools in its cells. Because the machines face each other, the loaders are configured in right- and left-handed versions.

Simplicity is a key value in automation. It makes automation easy to understand and the benefits easy to see. Simplicity keeps costs down. "Automatic loading gives us the best cost-to-benefit ratio," Mr. Pitzer says. "More automation would give us diminishing returns." On a practical level, simplicity contributes to flexibility. Novatech"s gantry loaders do not require customized grippers or pallet fixtures. Changeover is quick. There is less chance of setup error.

Automation does not necessarily mean untended operation. For Novatech, the value of automation is in enhancing the productivity of the machine and the operator. The shop does not operate the cells in the untended mode. The goal for automation is to match the output of operator-tended shifts with production requirements. "We could run one more carrousel full of parts at the end of the day if we wanted to, but that hasn"t been necessary," Mr. Pitzer says. The automatic loaders allow the operator to act as cell supervisor, taking care of duties without interrupting production. Many of these activities could be automated, but at considerable expense and complexity. The efficiency of the machines would not increase significantly from additional automation, notes Mr. Pitzer. "So why do it?" he asks.

With any automation, attention to details is important.Chip control is a good example. Novatech experimented with various turning insert grades and styles to find those that provided the most reliable chipbreaking function. Avoiding long, stringy chips is critical because resulting "bird"s nests" can interfere with the gripper or the chuck. Details about the chuck jaws proved to be important. The shop installed the more expensive one-piece quick-change chuck jaws because they had fewer places for chips to get caught on. For certain parts, the corresponding chuck jaws have been modified for better flow of compressed air during the chip clearing cycle. Coolant-fed toolholders are also used wherever possible. Coolant gets to the right place even if the regular coolant nozzles are not positioned optimally. Finally, attention to details requires good communication. For example, all setup notes and reminders are stored as text lines in the part program. That way, the operator does not need paperwork on a daily basis.

Operations on an automated cell must be balanced carefully. In some cases, parts can be processed on the cells in two operations, one on each machine. Typically, valve seats are processed this way. One side is completed on one machine and then transferred to the other machine to complete the other side. This approach is effective because the two operations are close in cycle time. Valves, in contrast, are usually processed in two operations, but machining the valve body requires a considerably longer cycle time than the stem side. Because the two operations are so unbalanced, both machines in the cell are assigned to turn the flow side. The stem side is then machined on a turning center outside the cell.

Automation is only one part of the productivity picture. Novatech continually looks for every opportunity to reduce cycle time and production costs. For example, the company originally used one forging to produce three different valves. This approach reduced the cost of the forge tooling. As quantities increased, it became more cost effective to design separate forgings for each valve so that the forging was nearer to net shape. The new forgings used less material and required less machining. These savings more than compensated for the cost of producing new tooling.

Partnering with the heat treater has also resulted in savings. With the promise of substantial business from Novatech, the heat treater invested in a larger capacity furnace. This allows Novatech to flex batch sizes more liberally without creating a bottleneck.

Novatech also studies product design for ways to improve product quality or reduce costs. For example, many valve bodies require a urethane seal around the OD. The company has developed and patented a technique for molding this seal directly to the valve body, streamlining the process of valve assembly.
