mud pump pony rod seal installation manufacturer

High-contact force sealing lip design coupled with compression set resistant Resilon seal material retains lubricating oil in the power end, eliminating necessity of shut down to add fluid

One of the challenges oil and gas companies face is sustaining seal life in challenging applications. Parker’s proprietary Resilon® material offers superior wear resistance and the highest operating temperature on the market to ensure performance and reduce downtime due to seal failure.

Plunger pumps are the workhorse of oil and gas fracking and drilling operations. They circulate high pressure fluid down the well and back up the annulus in both land and off-shore operations. When pumps are offline for planned or unplanned maintenance to replace leaking fluid, or worn seals, your operations stop.

Parker’s patented pony rod seal extends continuous service with a longer lasting, reliable design that retains lubrication and prevents leakage of hydraulic fluid in the power end and also serves as a rod wiper to keep contaminants out.

Pony rod also called the intermediate rod, is an important part of the connection between the crosshead and the piston rod. It is the key component that connects the power end and the hydraulic end of the mud pump. One end is connected to the crosshead and the other end is connected to the piston rod by a clamp. Its outer circumference is filled with a packing box assembly. In the reciprocating motion, the outer circle of the intermediate tie rod and the sealing member in the packing box rub against each other. To ensure it"s wear resistance, the outer surface of the intermediate rod is hard chrome-plated.

We can offer a wide range of extension (pony) rods for triplex mud pumps that are made of high quality alloy steel (40Cr). After strict heat treatment of quenching and high temperature, the rods have the features of high intensity on surface and high tough inside. The surface is treated with galvanization or nitrogen for high intensity and low abrasion.

We developed the Sur-Line system to prevent mud and other fluids from passing into the power section from the fluid end section of the mud pump, and to prevent fluid from going from the power section into the fluid end section.

The Sur-Line system uses a unique floating seal system that bolts into the wall between the power section and the fluid end section. The seals inside this housing seal against the OD of the pony rod, thus preventing fluid from passing between the two sections of the mud pump.

We carry parts to fit pumps from most major manufacturers. Sur-Line® systems are simple enough to be installed by the rig crew, or can be installed by our technical service department at the rig site.

We are a large drilling tools, Drilling rig spares, Water well drilling and mining pump part, Drilling mud pumps and Fluid End Expendables and mud pump spare parts manufacturer in China.

We make all fluid end modules, Ceramic liners, Hy-chrome liners, rubber replaceable and bonded urethane pistons and all spares for popular brand mud pumps.

Kerr Pumps manufacturers a wide variety of high quality valves and seats. We offer plenty of configurations and materials to choose from such as our more popular salt bath nitrided 17-4 stainless steel. We also keep in stock a full line of Well Service inserted valves and o-ringed seats.

All of our pony rod glands are machined in-house on one of our many CNC lathes. The level of precision and finish in each gland gives an incredible repeatability from part to part. This consistency extends the life of each seal and pony rod which keeps you pumping longer in the field.And Many More!

We believe that making incredible pumps is just part of the game. Our main focus is taking care of our customers. That is why we stock a full line of pump replacement parts. We do our absolute best in meeting customer demands and continue to strive to be the most responsive pump company.

Polyurethane has been an industry standard for dynamic sealing in hydraulic applications for more than 30 years. But polyurethane materials are not all formulated from the same hard- and soft-segment chemistry. The specific diisocyanate and chain extenders used in the synthesis of a polyurethane affect its physical and mechanical properties. When looking to achieve the best performance with mud and frac pumps, Parker’s Resilon® polyurethane is recommended. Our proprietary PPDI (p-phenylene diisocyanate) TPU formulation is specifically suited for injection molding of both large and small articles while retaining superior high-temperature performance.

The characteristics common to Resilon formulations make this PPDI class of material a leading choice for high pressure, dynamic sealing applications. These characteristics include exceptional:

"Our sales team members receive inquiries from well completion operators who are frustrated when they are interrupted and have to shut down to replenish gallons of hydraulic fluid lost from leaking seals. These operators and their service technicians who are in the field doing the change-overs make it known they "want the the tan colored pony rod seal," referring to Parker"s recognizable tan-colored Resilon 4300 formulation. Some operators are so pleased with the performance of the Parker pony rod seal they are demanding that the mud pump manufacturers install it as a condition to deploy their pumps on the job site."

Suction and Discharge Cover Seals. Our HGP Profile suction and discharge cover seals provide four times the reliable service life compared to traditional elastomer D-rings. Owing to its combination of unique geometry and Resilon 4300 polyurethane material, the HGP Profile resists wear due to the abrasive fluid proppant, high pressure and vibrating motion generated by high frequency pulsating pressurization. The tough, rugged material improves sealing reliability and minimizes degradation of fluid end mating hardware.

With well conditions becoming increasingly challenging and taking a toll on equipment and expendables, you require sealing products that will enable you to achieve greater production efficiencies, improve performance and reduce down time. Whether you service frac pumps, run completion operations, or build frac pump equipment, Parker’s proprietary Resilon materials can improve your bottom line by:
