"MAKE THE SHIFT”



The HPHT sealing stack that is reliable, easy to install, and easy on the bottom line.
The HPT Stack is a three-piece, HPHT, doubling acting piston or rod seal. Commonly used as a multi-vee seal stack replacement, such as the ATR or VTR sealing stacks. The HPT stack offers superior sealing performance and has good adaptation possibilities for diverse temperatures and media by the selection of suitable materials. The seal stack can hold 15,000 psi at 400°F (204°C) with passing ports at shifting pressures of 1,500 psi.
• Significant reduction in cost when compared with VTR/ATR, as well as other multi-component sealing Stacks
• 3-piece design with split guiding elements enables easy installation.
• Allows for reduced groove width
• Proven to operate at 15,000 psi at 392°F (200°C)
• Large element “lead-in” reduces the risk of damage while traversing ports.
• Pre-load can be modified to suit customer requirements.
Temperature Range: -40°C to 232°C (-38.2°F to 450°F)
Max Pressure: 20000 PSI
Max Surface Speed: 2.3 fps (0.7m/s)
All parts are measured on our Zeiss O-Machine and or Keyence CMM, which utilize optical and contact measurement technology in a comprehensive analysis. The O-Machine includes multi-sensor coordinate measuring, white light sensors for non-contact assessments and extremely accurate 3D scanners.
We follow AQL 2.5 levels 1 and 2 sample size quantities, and all molded parts are manufactured to RMA A2 tolerances.
Our rubber and plastic materials supply is diversified amongst the top compounders in North America. Each polymer has been qualified to meet typical exploration and production well conditions, including mechanical, tribological, thermal, and specific immersive properties.
