All PASAFE units offer economic, durable, and trouble-free discharge dampening. The dampener also include suction stabilization to protect against the stop and start motion of reciprocating pumps, as well as an acceleration-induced water hammer, activated by the opening and closing of the pump check valve.

  • Handles pressure requirements to 15,000 psi without any reduction of pulsation
  • Greater ease of use and economy of ownership with no replacements of internal parts
  • Available in carbon steel, stainless steel, duplex stainless steel, HDPE, and other materials for a customizable application
  • Broad capacity ranging from 1 to 600-gallons
  • In accordance with ASME Boiler and Pressure Vessel Code

Pulsation Dampeners


Annular BOP Equipment



Annular BOPs are a critical component of onshore drilling. They provide a pressure barrier by sealing around tubular goods, like drill pipes, during drilling operations to ensure optimal safety whenever a problem arises.

The annular feature only two moving parts, the hydraulic piston, and packing unit—reducing component wear. A replaceable packing unit wear plate eliminates metal-to-metal contact, extending time being overhaul and repair intervals.

The Hydril annular come in a variety of sizes ranging from 7 inch to 30 inch and have the below styles to choose from:

  • GK
  • GX
  • GL
  • MSP

Through one provider you get fast response, greater efficiency, assured accountability and more reliability–all leading to less downtime and  more production.
