mud pump valve seat for sale

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.

Valve seat extruder also called “Valve Seat Puller” is a service tool, which is used in the drilling sites for pulling the installed valve seats from mud pump fluid end module. During the process of replacing the valves seat and maintaining the mud pumps, this tool will be more effective to finish the maintance work with fewer manpower and shorter time.

The puller assembly can exert a force of over 200,000 lb on the valve seats. The complete comes with a hose so that the hand operated hydraulic pump can be placed at a safe distance from the mud pump during pulling operations. The hose, puller assembly, and pump are equipped with quick disconnect couplings for easy handling. The pump comes complete with a pressure gauge. The numerically controlled machined and heat treated puller head of high alloy steel offer maximum strength without the stress concentration characteristic of torch burned heads. The components are made from high quality cast steel for impact and wear resistance.

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 positive displacement mud pump is a key component of the drilling process and its lifespan and reliability are critical to a successful operation.

The fluid end is the most easily damaged part of the mud pump. The pumping process occurs within the fluid end with valves, pistons, and liners. Because these components are high-wear items, many pumps are designed to allow quick replacement of these parts.

Due to the nature of its operation, pistons, liners, and valve assemblies will wear and are considered expendable components. There will be some corrosion and metallurgy imperfections, but the majority of pump failures can be traced back to poor maintenance, errors during the repair process, and pumping drilling fluid with excessive solids content.

A few signs include cut piston rubber, discoloration, pistons that are hard to remove, scored liners, valve and seat pitting or cracks, valve inserts severely worn, cracked, or completely missing, and even drilling fluids making their way to the power end of the pump.

The fluid end of a positive displacement triplex pump presents many opportunities for issues. The results of these issues in such a high-pressure system can mean expensive downtime on the pump itself and, possibly, the entire rig — not to mention the costly repair or replacement of the pump. To reduce severe vibration caused by the pumping process, many pumps incorporate both a suction and discharge pulsation dampener; these are connected to the suction and discharge manifolds of the fluid end. These dampeners reduce the cavitation effect on the entire pump which increases the life of everything within the pump.

Poor maintenance — such as improper valve and seat installation — is another factor. Improper cleaning when replacing a valve seat can leave sand or debris in the valve seat area; preventing the new seat from properly forming a seal with the fluid cylinder, causing a pathway for a washout to occur. It is important to pull up on a seat firmly by hand and make sure it doesn’t pop out and is properly seated. The seats must be seated well, before resuming repairs. You should never reuse a valve seat if at all possible.

The fluid end is the most easily damaged part of the mud pump. The pumping process occurs within the fluid end with valves, pistons, and liners. Because these components are high-wear items, many pumps are designed to allow quick replacement of these parts.

A washout occurs when fluid and solids enter the area behind or underneath a valve seat and erode the sealing surface. Washouts are usually caused by one of three issues: a worn or cracked valve seat, improper cleaning of the valve seat and deck which creates a poor seat seal, and excessive sand content in your drilling fluid. Worn or cracked valve seats can allow fluid to enter the area around the valve seat and seat deck, creating a wash point on the valve seat and causing it to cut into the fluid cylinder and seat deck.

Additionally, the throat (inside diameter) can begin to wash out from extended usage hours or rather quickly when the fluid solids content is excessive. When this happens it can cut all the way through the seat and into the fluid end module/seat deck. This causes excessive expense not only from a parts standpoint but also extended downtime for parts delivery and labor hours to remove and replace the fluid module. With that said, a properly operated and maintained mud recycling system is vital to not only the pump but everything the drilling fluid comes in contact with downstream.
