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.

Features of Parker’s Resilon pony rod seal include

•Dual-function, single-seal design that replaces traditional two seal arrangements
•Chamfered metal can makes installation easy
•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
•Low drag excluder lip keeps contaminants out of hydraulic fluid
•Tough, wear-resistant Resilon polyurethane material resists compression set to maximize sealing performance and exclude debris
