The Caliber® well service valve and seat were designed for higher temperatures and pressures seen in today’s well service industry. The valves use our proprietary blend of urethane to ensure longer life.

Premium Oilfield Technologies offers a complete line of fluid end modules and components that are manufactured to OEM specifications and interchangeability. Our modules are machined to precise engineering tolerances. Each forging is machined and heat treated to maintain the best physical properties inside the module and on the surface, thus minimizing washing and stress cracking.

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...

Save time and eliminate the unsafe practices of using cheater pipes and sledge hammers to tighten and loosen valve covers. In current practice, one rig hand will hold a pipe in the valve cover holes and another will swing a large sledge hammer at the pipe in order to loosen or tighten the assembly. The Sur-Lock® Valve Cover system eliminates this unsafe practice and radically decreases the time it takes to remove valve covers, and replace valves and seats. Sur-Lock requires no special tooling and weighs about the same as a conventional valve cover assembly. With the use of an impact wrench or...

The Sur-Lock® Rod Link System was developed to provide a safer and faster way to unfasten the piston rod and remove the piston from the liner. Save time and reduce failure points by eliminating the need for a hydraulic pump. With our proprietary “taper lock” mechanism you simply use a standard wrench to unload the pins for removal. Our low profile water jet design can be used on pistons 4.5” and up. This system is fully interchangeable with P-Quip’s Rod Link System allowing you to effortlessly replace only the sub rod in “plug & play” fashion. .

Designed to drastically reduce the amount of time it takes to change a liner, the Sur-Lock® Liner Retainer eliminates the need for hammers to generate the necessary torque required by integrating a torque multiplying pinion and bull gear into a conventional liner retention system. We also reduced the weight of our liner nut to make change-outs safer and easier. The time to install a liner and tighten to the required torque is reduced to 45 seconds. .

Sur-Lock® Frac Fluid Ends come with the Sur-Lock Quick-Change Valve Cover. The fluid end is designed with the valve cover “threads” machined directly into the valve body. The valve cover drives straight into the body with an impact wrench or pneumatic torque wrench. Typically, a valve cover can be removed or replaced in seconds rather than minutes. Additionally, the valve cover can be torqued and pre-loaded to exact specified levels, thus preventing wash-outs from using other less-precise methods.

The Sur-Lock® strainer cover offers a 100% mechanical solution for increased operational efficiency, single person maintenance and reduced NPT (non-productive time). This new Sur-Lock system eliminates the unsafe practice of using cheater pipes and sledge hammers, and radically decreases the time it takes to remove valve covers and replace valves and seats. No special tools or hydraulics required Access strainer in seconds 5”10K flanged connection A...

Sur-Lock® Quick-Change products are designed to radically speed up the piston, valve/seat, and liner change process. Our Sur-Lock products eliminate the need for sledgehammers and greatly increase safety. SAFER. No more breaker bars and sledgehammers!FASTER. Dramatically reduce removal time for valves, valve seats, liners and pistons. EASIER. No special tooling required. No searching for hydraulic pumps or custom fittings. Installs easily with an impact wrench or torque wrench. View...
